Mobile Asphalt Lab Testing

摘要

Since 2006, FHWA's Mobile Asphalt Lab has traveled to six WMA projects to conduct material sampling and testing, and mixture performance testing, with the asphalt mixture performance tester and Hamburg Wheel Track Device. The projects include the following:rnA Missouri Department of Transportation (MoDOT) WMA demonstration project in St. Louis included construction of asphalt pavements using two additives and a water foaming product. The lab fabricated a large number of Superpave volumetric and asphalt mixture performance specimens for testing, in addition to loose mix sampled for later testing to investigate any effects due to reheating and residual moisture.
