New from the ARC:  Fatigue Testing Using the Asphalt Mixture Performance Tester 

 

The Asphalt Mixture Performance Tester (AMPT), a small servo-hydraulic testing device, was developed in the National Cooperative Highway Research Program (NCHRP) to measure the modulus and permanent deformation properties of asphalt mixtures in support of the AASHTO Mechanistic-Empirical Pavement Design Guide and future asphalt mixture design procedures.  Now, Asphalt Research Consortium engineers and technicians at Advanced Asphalt Technologies, LLC, of Sterling, Virginia, are expanding the capabilities of the equipment to measure the fatigue resistance of asphalt mixtures using continuum damage analysis.

Now’s the Time to Make

Conference (and Vacation) Plans!

 

The Petersen Asphalt Research Conference

(July 12 - July 14 in Laramie, Wyoming) brings you together with researchers, highway officials, producers and others working to advance the specification and performance of petroleum asphalts.

Research introduced and discussed at the Petersen Asphalt Research Conference has led to safer, longer-lasting and more cost-effective highways throughout the world for more than 45 years.

From fundamental research to field trials, the Petersen Conference is the essential forum for sharing and discussing current research now.

The Pavement Performance Prediction Symposium (July 15) lets you dedicate a full day to a single key aspect of pavement performance. (Watch for topic announcement.)

 

A Graphic Look at HMA Pavement Cooling Rates

in the Intermountain West

 

Asphalt Research Consortium researchers, highway agencies and motorists concur:  thermal cracking in the intermountain region of the United States is severe. Now, ARC partners at the University of Nevada, Reno, share their insights from studying pavement temperature histories and cooling rates of hot mix asphalt (HMA) pavements in ten states.  Click here to read more.
