Perpetual Pavement Design Updated with PerRoad 4.3

UPDATE: PerRoad is now on Version 4.4 with performance improvements and bug fixes. The Asphalt Pavement Alliance is hosting a webinar on May 30 to introduce Version 4.3 of PerRoad Perpetual Pavement design software. Developed at Auburn University, PerRoad uses the mechanistic-empirical design philosophy to estimate stresses and strains that would prove detrimental for fatigue cracking or structural rutting.

A Race Against Time

The Mid-Ohio Sports Car Course is a permanent road course with both a 2.4-mile, 15-turn configuration and a 2.25-mile, 13-turn lay-out located in Lexington, Ohio. It was originally constructed in 1962 for weekend sports car racing by local businessmen. In 1972 and 1990, the entire 2.4 miles of road course was resurfaced. The track is often referred to as the “country club” of racetracks.

Hallet Motor Speedway

Hallet Motor Speedway is one of many racetracks across America that has benefitted from asphalt smoothness and quick speed of construction.   After opening in 1976, the track was beginning to show its age.  A quick construction turnaround ensured a safe surface for a highly technical racecourse in time for opening day.

Harris Hills Raceway Rehab

For those who live near San Marcos, Texas, Harris Hills Raceway offers the perfect opportunity for racing aficionados to get together, race their own vehicles on a challenging track, and enjoy the camaraderie of like-minded enthusiasts—all without the risk of getting a ticket! You could say that racetrack is an oasis for “civilians” with the need for speed. With a thriving client base to satisfy, the condition of the track is an important investment for the family-owned business. When owner Bo Rivers realized it was time for some much-needed rehabilitation, he began looking for a paving contractor that could meet the track’s unique needs.

Phase IV NCAT Pavement Test Track Findings

The NCAT Pavement Test Track, operated by the National Center for Asphalt Technology (NCAT), has been a successful pavement research program for many reasons. First, the 1.7-mile oval test track is a unique accelerated pavement testing facility that brings together real-world pavement construction with live heavy trafficking for rapid testing and analysis of asphalt pavements. Since the test track is funded and managed as a cooperative project, highway agencies and industry sponsors have specific research objectives for their section(s) and shared objectives for the track as a whole. The results of the experiments typically are not abstract or ambiguous; they are easy to interpret, so findings are quickly put into practice by sponsors.
