Applied Research Associates delivered two pavement testing machines called Accelerated Transportation Loading System (ATLaS) to the Federal Highway Administration (FHWA) in Virginia.
Applied Research Associates, Inc. (ARA) recently delivered two of its pavement testing machines called Accelerated Transportation Loading System (ATLaS) to the Federal Highway Administration (FHWA) in Virginia.
ATLaS enables agencies like the FHWA to effectively evaluate, validate, and implement new construction materials, infrastructure design, construction practices, and new maintenance and rehabilitation technologies in a shorter amount of time that would otherwise take years to assess test tracks or long-term monitoring sites with live traffic.
Each ATLaS pavement test machine delivered to the FHWA is 77 feet long and weighs 75,000 pounds.
By implementing an accelerated pavement test (APT) program, an agency can save millions of taxpayer dollars by selecting the best construction materials, improving the construction specifications, and improving the infrastructure lifespan.
“The successful delivery of these two ATLaS platforms is a result of our dedicated team’s hard work, commitment to excellence, and strong relationship with our customer,” said Matthew Fordham, division manager of ARA’s Integrated Products Division.
“Our capture team, to the design and manufacturing team, are committed to excellence. As FHWA is the epicenter for accelerated pavement test systems, we are proud to work with their team, supporting efforts to build a better transportation future.”
ATLaS devices provide a unique full-scale state-of-the-art APT tool to generate applied infrastructure research that benefits an agency in a very short time. The ATLaS can operate 24 hours per day, seven days per week, 365 days per year to induce truck, airplane, or railroad loading to highways, bridges, and railroad systems.
ARA is the sole developer and manufacturer of the ATLaS, which is available in several models. Since ARA’s first ATLaS delivery in 1997 to Ohio University, ARA has delivered ten accelerated pavement testers to research institutes across North America and China.
Our 63,000-square-foot manufacturing facility in Randolph, VT, is home to experienced engineers, designers, and technicians with decades of experience in geotechnical fields.
All of our APT platforms are custom built to accommodate traffic-induced load capacities, budget constraints, and site restrictions.
ARA follows a rigorous standardized system engineering approach with a robust data-driven quality program. Other solutions include asphalt testing equipment, asphalt compaction testing equipment, and asphalt density testing equipment.
ARA also offers on-site, hands-on training covering all aspects of user operation, safety, maintenance, troubleshooting, and repair of the system. For more information on ATLaS, visit go here.
The ATLaS can produce 15,000 and 7,500 loaded passes at 7.5 MPH 24 hours in either bilateral and un-directional modes, respectively.
What is the range of applied loads that FHWA’s ATLaS can apply to their test areas?
The ATLaS delivered to FHWA can produce a range of loads between 9,000 and 22,500 pounds to the testing surface. The system can vary the loads over an experiment with our programable test matrix user interface.
What are the test for pavement or asphalt?
To ensure the quality of bitumen, several tests are performed, which are as follows.
– Ductility test.
– Flash and Fire point test.
– Float test.
– Loss on the heating test.
– Penetration test.
– Softening point test.
– Specific gravity test.
– Viscosity test.
What is the Accelerated Pavement Testing (APT)?
Accelerated pavement testing (APT) relates to the controlled application of a prototype wheel loading, at or above the appropriate legal load limit to a prototype or actual, layered, structural pavement system to determine pavement response and performance under a controlled, accelerated accumulation of damage in a compressed period.
