ANNOUNCING IT TO THE WORLD

The combination of the new research center and test track at the National Center for Asphalt Technology in Auburn, Alabama, represent a unique partnership of industry, academia, and the highway departments. The design of the test track fits with the concept of the perpetual pavement being developed by the hot mix asphalt (HMA) industry. Perpetual pavements use multiple layers of durable HMA. The goal of the test track is to accelerate truck traffic loading to perform 10 million equivalent single axle loads over a 2-year period. That is equivalent to 10-12 years of traffic on a fairly high-volume interstate highway. One of the first orders of business will be to characterize test track samples with a battery of different tests. Such tests will include the resilient modulus test, the indirect tensile strength test, various pavement deformation tests, extractions of the asphalt cement from the aggregate, and various tests on the asphalt cement binders and aggregates. The primary goal of the research is to find which test or tests can best predict rutting. Rutting tests include three loaded wheel testers, three types of creep testing, and tests involving properties of gyratory compactor samples. In addition, first-round test track research will include all types of surface distress, including cracking, friction testing, smoothness testing, and tests with the falling weight deflectometer.
