Basic Asphalt Recycling Manual | B.A.R.M

What you will learn:

The growing demand on our nation’s roadways over that past couple of decades, decreasing budgetary funds, and the need to provide a safe, efficient, and cost effective roadway system has led to a dramatic increase in the need to rehabilitate our existing pavements. The last 40 years has also seen a dramatic growth in asphalt recycling and reclaiming as a technically and environmentally preferred way of rehabilitating the existing pavements. Asphalt recycling and reclaiming meets all of our societal goals of providing safe, efficient roadways, while at the same time drastically reducing both the environmental impact and energy (oil) consumption compared to conventional pavement reconstruction.

The Board of Directors of the Asphalt Recycling and Reclaiming Association (ARRA), in their ongoing commitment of enhancing and expanding the use of asphalt recycling and reclaiming, recognized a need for a “Basic Asphalt Recycling Manual”. The manual was needed in order to expose more owners, specifying agencies, consultants, and civil engineering students to the value and current methods of asphalt recycling. To fill that need, this manual was produced to serve as a handy one-stop reference to those starting out in one of the various forms of asphalt recycling. In addition, it is hoped that this manual will provide additional useful information to those already in- volved in asphalt recycling.

This manual is not written in such detail so that one could use it to completely evaluate, design, specify, and/or construct an asphalt recycling project. It does however, provide information on:

• Various asphalt recycling methods
• Benefits and performance of asphalt recycling
• Procedures for evaluation potential projects
• Current mix design philosophies
• Construction equipment requirements and methods
• Quality Control/Quality Assurance, inspection and acceptance techniques

• Specification  requirements
• Definitions and terminology

Sufficient information is provided so that a rational decision can be made with respect to the feasibility and/or cost benefits of asphalt recycling. From that point, detailed design issues will need to be addressed by those experienced in asphalt recycling techniques prior to the final project design, advertising, tendering or letting and construction.

The benefits of asphalt recycling include:

• Reuse and conservation of non-renewable natural resources

• Preservation of the environment and reduction in land filling

• Energy conservation
• Reduction in user delays during construction

• Shorter construction periods

• Increased level of traffic safety within construction work zone

• Preservation of existing roadway geometry and clearances

• Corrections to pavement profile and cross-slope

• No disturbance of the subgrade soils unless specifically planned

• Such as for Full Depth Reclamation (FDR)

• Improved pavement smoothness Improved pavement physical properties by mod- ification of existing aggregate gradation, and asphalt binder properties

• Mitigation or elimination of reflective cracking with some methods

• Improved roadway performance
• Cost savings over traditional rehabilitation methods

It is important to recognize that asphalt recycling is a powerful method to rehabilitate pavements. When properly applied, it has long term economic benefits allowing owner agencies to stretch their available funds while providing the traveling public with a safe and reliable driving surface.

It is also important to recognize that, although asphalt recycling technology and methods has advanced, not all roadways are appropriate candidates for asphalt recycling. With the almost endless supply of roadways needing rehabilitation, it would be a dis- service to the public and the industry to use poor judgement in attempting an inappropriate recycling project. Hopefully, with this manual and the advice of those experienced in asphalt recycling, only projects that are suitable candidates will be undertaken.

The primary focus of the manual is on the in-place and cold recycling of asphalt pavements. Hot recycling of asphalt pavements through various types of asphalt plants is a well established recycling method. There is a wide variety of information on the subject available from well established sources and therefore has not been covered in any detail in this manual.

I-88 Rubberized Asphalt Project

Last year, Asphalt Plus conducted a trial project of dry process crumb rubber modified asphalt on Interstate 88 near Rochelle, Illinois. The project included the laboratory evaluation of two asphalt mix design and placement of two lane-miles of pavement on I-88.

The first mix was:

• Friction SMA (ILDOT)
• 34% ABR (5% RAS and 8 lbs of rubber mix per ton)
• No RAS content

Tests suggest comparable Hamburg and DCT performance between dry process CRM asphalt and PMA.

• 2 vs. 2.5 mm rut respectively
• 602 vs. 566 DCT respectively

The second mix was:

• 12.5 N75 Fine Surface Graded Mix (WIDOT)

Lab testing of the WIDOT mix with and without engineered dry process rubber showed the rubber additions significantly improved mix performance.

Presence of rubber improved:

• Hamburg rutting from 8.2 mm at 10,000 passes to 3.4 mm at 20,000 passes
• Increased DCT results from 358 to 482

Modifying The Plant

The Curran DeKalb plant was modified for dry process asphalt production in a matter of a few hours.

Using a loss-in-weight feeder system:

• Engineered crumb rubber was injected into production with a high degree of accuracy
• Plant production of CRM asphalt at full production rates occurred without interruption
• Two mix designs were produced in sequence with minimal waste

The asphalt mixes were trucked 40 miles on a cool day (55 F at start), and placement temperatures ranged from 235 to 280 F off the trucks.

The Finished Product:

• Finished without any tearing
• Vibratory rollers produced specified compaction without special effort and without stopping plant operations

Performance evaluations will continue in the field following a winter of service. The existing record of technology field performance in colder climates strongly suggests that the use of dry process engineered rubberized asphalt mix designs will be permitted as a competitive alternative to other forms of modified asphalt. The cost advantage suggests this process will benefit both producers and road owners.

Georgia Pavement Management Software

SOME state DOTs are telling their local agencies to use a pavement management system that is dated or not capable of running budget scenarios on the most cost effective treatments or take full advantage of pavement preservation….

WORSE than that they are not themselves using the actual software they are trying to get you to use….

MOREOVER, a local agency like yours no matter how small has hundreds of millions of dollars of valuable roadway assets, but you don’t have enough money to maintain them

Want to do this right, then call us to set you up, or at least get the book and go through IPMA Academy….404-953-0131

Ok, a quick disclaimer reminder here as you enjoy the book, we are not here to promote any one product, service or company.

We’ll talk about software like MicroPAVER™ and StreetSaver^® pavement management software, on the consulting side of the business, we set up about 14 or 15 local agencies in the Southeast with StreetSaver^® pavement management software. We also used MicroPAVER™ to do pavement manager for the US Corp of Engineers at Dugway Proving Ground in Utah. On the teaching side we cover both software in detail in IPMA™ Academy www.ipmaacademy.com and do private customized training on both. There may be many different ways to evaluate and manage your pavments, these two software programs we discuss may be the only two that follow ASTM 6433 verbatum. The reader is encouraged to look at all of the options, not just the ones that we discuss in this book.

That being said, know that many cities and counties across this country and the world use these two programs with great success.

CITY OF WINDER, GA

For those of you who are interested you can listen in to www.betterroadradio.com the only podcast on the planet dedicated to saving our crumbling roads, Episode 3 to hear a session from Blair and Scott as they discuss the key elements of setting up your pavement management system successfully.

At the end of the day even with all the people that have gotten involved in this loop for a mere 2 or 3 cents per square yard to implement a pavement management system and correlate all that back at their office and have this network level inventory of all the roads just like you said with the functional class codes what do we have for pavement types? What they heck are we going to do in 10 years, what are we going to do in 20 years?

Well the bottom line is in the case of Richmond which is a perfect example, if they can use the eco-efficient preservation in-place recycling techniques and save let’s say 20-30% of the budget so now they are saving $8.00 or $9.00 per square yard on any one given project, they are spending 3 cents that looks to me like a $7.97 net gain.

Now for those of you who don’t know how to collect that data or use your best guestimate or have your staff do the best guestimate you know we’ve had the IPMA™ Tip of the Week where we’ve had the fire hydrant where we taught you guys how to back calculate the base M&R date based on how many overlays we have, when was the subdivision originally built.

If you haven’t watched that episode, go to our YouTube Channel IPMATV and look up that www.youtube.com/user/ipmatv segment on the fire hydrant and back calculating the last M&R date. (as a reminder, if you register your Book on Better Roads at www.thebookonbetterroads.com/register you wont’ miss a single episode of IPMA™ TV).

Reno County Commission Introduced to Pavement Management by The Barnhardt Group

Written By: John Green

The Hutchinson News

jgreen@hutchnews.com

A Georgia-based pavement management contractor currently doing assessment work in Wellington made a presentation to the Reno County Commission Tuesday on the benefits of having a pavement management system.

Reno County Public Works Director Dave McComb, who is interested in developing such a system for the county, invited Blair Barnhardt of The Barnhardt Group to the meeting.

There is no money in the current county budget to implement such a system, but McComb said he would like the commission to be prepared to make a decision on whether enter such a contract in advance of the 2017 budget.

The purpose and benefit of a pavement management system, Barnhardt explained, is identifying preservation work that can extend a road’s life, rather than rebuilding roads after they have deteriorated, which is a more cost effective use of public works dollars.

Barnhardt’s company takes core samples from identified roadways to determine their makeup, assesses existing conditions of the road surface and subsurface, and then identifies up to 20 “distressers” that are impacting the life and condition of the road.

He gets down on his hands and knees, for example, Barnhardt said, to measure the length, depth, and severity of cracks in the pavement.

From the data gathered on the roads, a software program then makes recommendations on which of various methods of preservation work would best extend the life of the road at the most economical cost.

Spending 2 to 3 cents per square yard on assessment, Barnhardt contended, can save $10 a square yard on maintenance. Once the management system is in place, he said, “using the right treatments in the right place at the right time” can stretch road dollars by at least twice as much. Moreover, the industry is developing new preservation methods all the time.

So, rather than spending $1 million per mile to replace a deteriorated road, the county might be able to spend the same amount on preserving 20-plus miles of road and, eventually, with saved dollars, replace that deteriorated road.

David Edwards, of GSI Engineering in Wichita, which has partnered with Barnhardt in assessing projects identified by the management system, joined Barnhardt at the meeting.

Edwards noted that using the system might require the commission to allow already deteriorating roadways, which are already resulting in complaint calls to the commission, to deteriorate further while they do work on roads that appear in good condition, which may be politically difficult.

“You save what you can save first, and do the really bad roads down the road,” he said.

The commission will be able to point to hard evidence from the system that the decisions are more economically efficient, he said.

McComb, already interested in pavement management, learned more at a recent “lunch and learn” event sponsored by The Barnhardt Group.

The county has a system in place to sand seal so many miles of road each year, and pave so many miles of arterial with a cold asphalt mix, McComb said. However, he was interested in seeing what could be done, for example, to preserve the work done on Yoder Road 10 years ago, rather than spending millions to mill and asphalt the road again in 5 years.

“How can we get the best bang for our buck?” he said.

McComb also expressed a desire to have a system in place for determining road project spending that will still be in place when he is gone.

Asked by Commissioner Brad Dillon how their fee would work, Barnhardt said it is based on a per-mile contract, but it could be spread over several years, done all at once for a discount, or on a not-to-exceed pro-rated basis.

More Roads, Less Money, Less Carbon Footprint: Graniterock IPMA™ Charter Members Spotlight

From Graniterock Tools Newsletter:

Five reasons your roads need Cold-In-Place Recycling

As California faces a growing crisis of crumbling roadways, it turns out there is a way to tackle our aging, broken up streets without going broke or sending another bond measure to the voters. Cold-in-place recycling (CIR), a solution already used by many cities and counties throughout the San Francisco Bay Area, is a road rehabilitation technique that recycles the top 3-6 inches of existing pavement to improve roadway surfaces. CIR recycles your existing road, without the need for grinding or new materials, which eliminates waste sent to landfills and all the truck trips that go along with it. And, CIR is more affordable than traditional remove and replace methods. Graniterock’s CIR business uses the Wirtgen 3800CR, a highly trained crew, and a Caltrans-certified mobile laboratory to rehabilitate roadways while reducing  material waste and extensive trucking needs typically seen on base repair and overlay projects. Cold-in-place recycling has become an increasingly popular alternative to conventional road maintenance methods, for five big reasons: 1.) Saves 20%-40% of your road maintenance budget 2.) Cuts greenhouse gas emissions by 52% 3.) Reduces truck traffic 90%, creating a safer working environment 4.) “Zero waste” approach to pavement rehabilitation 5.) Faster construction times compared to traditional remove and replace methods The City of San Jose Public Works Department, responsible for 6,000 lane miles, has incorporated CIR as part of its pavement maintenance program for the past six years. Along with Caltrans, San Jose has created its own CIR specification to use on a project-by-project basis. “The main reason we like CIR is because it minimizes the traffic impact and the number of trucks coming in and out of the project site,” San Jose’s Associate Engineer Frank Farshidi said. “We don’t have to close the road and residents really like that. We’re not hauling new material from the plant, which makes it a more sustainable process.” Several engineers from the City of Santa Clara visited a recent Graniterock CIR job on Vistapark Drive in San Jose to watch the process and determine if it’s something that would help chip away at the backlog of crumbling streets. “CIR is a brilliant solution to one of our biggest problems – really old and aging residential streets,” said Jim Parissenti, principal engineer for the City of Santa Clara Public Works Department. “The CIR method will actually let us catch up on our backlog.”

Way to go Brian!  I found this is “The Kansan”…

An alternative roadway reparation technique utilized by the Harvey County Road and Bridge Department to save on costs has earned star marks after a recent round of testing.Over the past year the county has contracted out 19.3 miles of paved road to Dustrol Inc., Towanda, to be resurfaced using Dustrol’s hot-in-place recycling technique rather than a traditional surface overlay.

“What they decided to implement this year that they didn’t last year was a profilograph,” said Jim Meier, road and bridge superintendent for the county. “What the machine does is reads the defects in a road.”

The definition of a defect is any imperfection measuring 4/10 of an inch bump over 528 feet of roadway.The company administered the test on five miles of a recently completed stretch of East First Street starting at Rock Road and extending to the western border of Butler County.

“They read the results before and after (the work).” Meier said. “The before was a total of 361 defects on East First. When they took the profilograph back over that when they were done they had zero.”

Meier said the process cost the county just more than $1.5 million. He said that number is about 65-percent of the cost of a traditional two-inch overlay over the same mileage.

“Along with what else a two-inch overlay does is it raises the road,” Meier said. “Over time you actually narrow the road. The hot-in-place takes the existing two inches of pavement, in this case, picks it up and rejuvenates the aggregate.”

The fresh asphalt is then put back where it originally came from in a single operation requiring about 1,000 feet of equipment.

“We do still have roads that this is not a viable solution for,” Meier said. “Those roads will still get an overlay.”

Meier said while not a catchall solution for the resurfacing of county roads, he hopes to use the hot-in-place process as an ongoing solution for a significant portion of county mileage.
