However,current pavement design procedures and modelsare based on the performance of older mixturesdesigned with the Marshall system. Therefore, it iscritical to monitor the performance and materialcharacteristics of Superpave project sections andto establish a database of observations so thatdesign procedures and models can be updated. Inaddition to the changes in this material system,the adoption by the American Association ofHighway and Transportation Officials (AASHTO)of a new standard for design, the Mechanistic-Empirical Pavement Design Guide, has createdadditional needs for field data to update designmethodologies
