NYC DOT exploring WMA rubberized asphalt

Staten Island RMA

Trap Rock Industries is helping the New York City DOT evaluate rubberized asphalts that incorporate Evotherm warm mix technology. "There a plenty of positives to rubberized asphalt," Galileo Orlando, DOT deputy commissioner for Roadway Repair and Maintenance, said according to Staten Island Advance.  The rubberized asphalt should be more durable, quieter and offer environmental benefits.

According to Better Roads, "the city is curious to find out how well it will perform during New York’s varying seasonal climate. That’s why West Fingerboard, from about Radcliff Road to Steuben Street, will use three different types of asphalt: traditional asphalt, rubberized asphalt, and a cheaper form of pelletized rubber asphalt. The goal is to learn how each mixture will weather over the next few months." The city will watch the roadways through tree seasons - winter, spring, and summer- to evaluate performance.  


WMA Continues Growth


More contractors started using chemical additive WMA in 2013, growing by 2.7%,  while fewer contractor used plant foaming in 2013. NAPA and FHWA released their survey of 2013 construction practices, finding that almost a third of all asphalt produced used warm mix technologies. The 106.4 million tons of WMA produced in 2013 represents a 23% increase from 2012. 

Use of reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) also continues to rise with 73.5 million tons of RAP and 1.7 million tons of RAS used. NAPA notes that "reclaiming and reusing the asphalt cement in RAP and RAS saved about $2 billion in 2013 compared to the use of virgin materials."

More factoids:

  • EVERYONE uses RAP: 100% of contractors reported using RAP in 2013
  • OHIO had 100 contractors completing the survey, followed by California at 75 contractors.
  • TONNAGE reached a new LOW: overall estimated asphalt tonnage of 350.7 MM tons was the lowest since the survey's inception in 2009.
  • FLORIDA averages the highest RAP usage percentatge at 32%
  • NORTH CAROLINA increased their average RAP usage the most, from 15% in 2012 to 26% in 2013
  • MORE STATES reported using RAS and GTR in asphalt mixes

The survey was conducted in mid-2014. Results from 249 companies with 1,281 plants in all 50 states, the District of Columbia, and Puerto Rico, along with data from State Asphalt Pavement Associations for 38 states, were used to compile the report. A full copy of the survey, including state-by-state appendixes can be downloaded from www.AsphaltPavement.org/recycling.

Dedham - 1st in MA


For its FY 2015 paving program, the Town of Dedham, MA took a leading role and became one of the first municipalities in the Massachusetts Commonwealth to require the use of warm mix asphalt.  With the intent of creating longer lasting pavements, Dedham’s Public Works Director, Joe Flanagan, added a WMA requirement to his specification that called for the use of an additive capable of a minimum temperature reduction of 50o F.  With all of the paving being conducted in September and October, the extended workability of the mix was also appealing.   

Contractor TL Edwards chose Evotherm for the project because of previous experience they had out of their plant in Plymouth, MA.  This would be the first time they produced WMA at their Avon facility.  After using Evoterm on several projects, Plymouth Operations Manager Steve Edwards, said “I have seen a lot of changes in the asphalt industry over the years, and I am excited about Evotherm.  I can really see the benefits in using it”

About 5000 tons of WMA were placed in the first phase of the program in September.  With the arrival of the cool New England weather, morning temperatures were dropping below 40 oF.  Using Evotherm allowed the paving to begin at the scheduled time of 6:00 am on an unseasonably cold Saturday, keeping the project on schedule and minimizing user delay of a major arterial in town.  Even with the low temperatures, compaction wasn’t an issue.  The Town’s engineering consultant, Vanasse Hangen Brustlin (VHB) was tasked with quality assurance.  VHB Pavement Engineering’s Jose Otero, commented, “We did see an increase in density, but what we really noticed was a big increase in uniformity of density”.

Dedham’s annual paving program is expected to be about 15,000 tons total this year, all of it being Evotherm WMA.  Joe Flanagan summed it up by saying, “so far I’m impressed.  I’m looking forward to continued success with the rest of the program and making it a permanent part of our specification”.

VOTE! America's Transportation Awards

Colorado's September 2013 Flood Response is one of top 10 projects selected for the 2014 America's Transportation Awards competition sponsored by the American Association of State Highway and Transportation Officials, AAA, and the U.S. Chamber of Commerce. "These 10 remaining projects are the best of the best," said Bud Wright, AASHTO executive director. "This competition recognizes excellence in project delivery. It's about saving time and taxpayers' money and improving the ability of people, manufacturers, farmers and service providers to move themselves and their goods, reliably, every day."
The nation will decide through online voting which of the projects will receive the People's Choice Award. A panel of experts will select the Grand Prize winner. Online voting begans Sept. 8, and will continue through Friday, Oct. 24, at http://AmericasTransportationAwards.org. Individuals are welcome to vote up to 10 times per day for their favorite projects.
Colorado Department of Transportation's $50 million quick and efficient response to damage caused by the major September 2013 floods greatly improved the lives of state residents. CDOT coordinated with the National Guard, local leaders and residents, and private contractors to reopen the last of the closed roadways in December 2013, just 10 weeks after the catastrophic event. You can learn more about Evotherm's involvement in the project here.
The Grand Prize and People's Choice award winners will each earn a $10,000 donation from AASHTO on behalf of the winning state DOT to a charity or scholarship fund of its choosing. Both awards will be presented Nov. 23 at the AASHTO Annual Meeting in Charlotte.
