This report comprises results from the first part of the three year research program which aims to develope criteria for asphalt and additives based on domestic pavement-performance. This year project intends to investigate the existing asphalt binder specifications and their related theories. And pilot section of PMA(Polymer Modified Asphalt) was constructed for the purpose of future field investigations. In this study, Superpave, which is new testing methods to characterize rheological, critical and durable properties of asphalt binder, is considered reliable for giving the asphalt binder properties. Thus, exising asphalt modifiers can be estimated through Superpave analysis system for the economical purpose.
