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.Screen Shot 2016-05-19 at 5.49.06 PM

  • 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 PlantScreen Shot 2016-05-19 at 5.49.15 PM

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.

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.

The Barnhardt Group to Conduct Pavement Survey in Wellington, Kansas

    • City discusses street work

By Derrick Mead
Wellington Daily News

Posted Sep. 17, 2015 at 2:34 PM

It’s probably no secret that many of Wellington’s streets could use some work. A step has been taken in that direction, as last Tuesday’s city council meeting focused heavily on the discussion of city streets.

The resolutions portion of the meeting centered around potentially authorizing City Manager, Roy Eckert, to execute an agreement with the Barnhardt Group of Kennesaw, GA, to conduct a pavement management study in an amount not to exceed $24,000.

Jeremy Jones, Director of Public Works, was present at the meeting to present to the council the reason behind the move. Jones explained that many streets in town are made up of different surfaces and have different treatments on them and underneath them. Without a comprehensive knowledge of the history of the streets, it is difficult to go about properly maintaining them in the future.

“We know that we have a poor base material under a number of our roads,” Jones said.

Jones also referenced a past experience with “band-aid” fixes, which he acknowledged were sometimes necessary.

However, this move to bring in the Barnhardt Group will at the very least give the city the necessary knowledge to make more long-term improvements moving forward as opposed to the band-aid fixes of the past.

Jones stated that there are officials who have been around a long time who don’t even know what is underneath some of Wellington’s streets because of how long they’ve been around and the number of times they’ve been resurfaced. The survey by the Barnhardt Group would supply the City with all of that information, which should prove invaluable when it comes to future street rehabilitation and maintenance.

Councilman Kip Etter questioned whether Wellington had enough streets to justify this move.

“The City of Wellington is responsible for approximately 60 miles of paved streets and seven miles of gravel roads with an estimated value of $40 million,” Jones told the council.

“We’re going to spend this money one way or another, but I would feel much more responsible financially and sleep better at night if I knew I was spending money in the future that’s going to get us farther. Our current techniques simply aren’t working,” Jones added.

Etter also wondered if the results of the pavement management study would allow any capacity to adjust if the City has a preference of what streets they’d like to work on as a priority.

Jones told the council that the study would show the City what condition various streets are in and why, but that the City could still determine its own

“All of us up here realize that in order to move forward, Wellington has to know where it came from and where we want to go, and that is just part of that long-term strategic planning,” Mayor Shelley Hansel said.

“I recognize $24,000 is a lot of money, but it is about 0.5% of our total estimated value of our street system,” Jones added. “So we’re going to spend half a percent to do a study to see how to proceed over the next 10-plus years.”

The pavement management study, which was approved unanimously after about 30 minutes of discussion, is expected to begin soon and take about three weeks to complete.

Pavement Survey – Our Set Up – Easy Equipment Implementation

Over the years a lot of folks have asked Jason and I about our set up in the field for the RV, the Rhino, the core drills we use, the measuring wheels, the distance measuring instruments etc.

As you may have already figured out by now, I am basically an open book in this respect, pardon the pun here. What I mean is that my underlying goal in life is to get this country out of economic disparity by creating better roads for less money, and any one task that moves us closer to that goal, whether it is shortening your pavement management learning curve, hanging out with you in your city or county to help you put the pieces together, or to hand over the keys to the equipment that we use on a daily basis, my only goal is to provide you with the tools to get you to pavement management RockSTARDOM!

So I just took a few minutes in the yard the other day, gathering up all of our tools so Jason and I could start a new project in Colorado this week. So below is a bunch of photos of our set up for boots on the ground expert pavement distress evaluation. You can replicate this set up for under $20,000.00 and be performing your own work in two weeks. I went ahead and put a photo in of what some of our IPMA™ Academy are doing for their set up as well just for comparison sake.

I think you know this already, but if you should have any questions at all along the way, shoot me an email 24/7 at blair@ipma.co and I will get you the answer that you need to set up your own equipment. I have provided our most up to date equipment photos, along with some upcoming equipment that we plan to acquire. If you are a consultant, or agency person I hope this BONUS Chapter helps you with your decision making process. There is no sense re creating the wheel here, and with 4 million miles of roads in USA, I think there is plenty of pavements to be managed by all!

Award Winning Cold-in-Place Project in Canada

For those of you who don’t know me, I spent the earlier part of my career in Canada growing the pavement management, in-place pavement recycling and preservation business across the country. I also spent several years on the board of directors with www.arra.org as the CORE Chairman, the committee on recycling education. I am putting this Bonus Chapter in for several reasons, some of which I will keep to myself, some I would like to share with you.

One, anyone in this day and age can set up a Google Alert on pretty much any topic they so desire. I choose to set up a handful on all things that we talk about in the book. So today, as I write the final chapters, I am sharing information with you from the internet that is current as of today’s date. You can see this just like me right here at http://www.bayshorebroadcasting.ca/news_item.php?NewsID=65323 and thanks for sharing this story with our audience Bay Shore Broadcasting in Canada!

Two, for decades I have asked local agencies to embrace pavement management, in-place recycling and pavement preservation. It WORKS! There are counties and cities across the world DOING IT!   It is not NEW! Let me repeat, it WORKS, there are folks just like you DOINT IT, and it WORKS!

Three, this is a great example of a success story, but reputable contractors teaming up to share their knowledge with the world via the internet. This same type of Internet sharing of knowledge will eventually show enough Stringbender™ success stories to crumble down the walls that the Naysayers have put up. Trust me on that one!

Four, we need more stories of success just like this one to CRUSH THE NAYSAYERS!

Five, when I listen to the MP3 here http://www.bayshorebroadcasting.ca/downloads/audio/mike_alcock_award.mp3 it reminds of when I used to live in Canada LOL!

Six, I immediately recognize all of the names in the story, having spent many long days working for these same folks at some point. Many that used to be local agency folks are now working on the private sector side of the fence!   Hope you all are doing alright up there folks!

Seven, I wanted to remind the readers and listeners here today that in addition to IPMA™ where local agencies join for free at http://ipma.co/ there are many other great trade associations out there. I have tried to stay on the high road throughout the book, and want to end on that positive note by asking you to consider taking part in other trade associations such as http://www.arra.org/ and http://slurry.org/ so you get a chance to hear things from a different perspective and formulate your own unique blend of wisdom back there at your office!

Eight, this is a great example of industry partnering together for a common goal. We need to all work together if we are to resurrect our economy. As the author of this book I want to remind the readers that we are willing to partner with any reputable association, firm, or person that will further our movement – blair@ipma.co

Nine, the consulting side of the business at http://thebarnhardtgroup.com/ works anywhere in USA and Canada to serve our local agencies in any way we can with their pavement management. I didn’t want you folks up there to feel left out in the book. Our RV can travel wherever we need to be to save our crumbling roads.

(Huron County)-


Huron County’s Public Works Department has copped an industry award for its asphalt recycling program.

At Huron’s Committee of the Whole Day One session Wednesday (April 9th), Bentley Ehgoetz of Lavis Contracting and Trevor Moore of the Miller Group made the presentation to the County’s Dave Laurie and Mike Alcock.

Alcock explains that the County’s Cold In-Place Asphalt Recycling Program, in operation since 1998, has won the 2014 Charles Valentine Award for Excellence.

The annual accolade is a presentation of the Asphalt Recycling and Reclaiming Association (ARRA), and submissions are made from all over North America.

The County’s Civil Engineering Technologist tells Bayshore Broadcasting News that fully half of Huron’s 730 kilometre road network is topped with the recycled asphalt mix.

Alcock says the process saves money by re-using the asphalt with new emulsion.

He says the blend is less prone to cracking.

Trevor Moore, the Corporate Director of Technical Services with the Miller Group notes that Huron County was a pioneer in the use of milling machines to achieve a wider road swath during the paving process.
