ABSTRACT
Aggregate and four kinds of asphalt (30#, 70#, 50# asphalt and SBS modified asphalt (I-D)) selected in this study were tested about main technical performance indexes based on Test Method of Aggregate for Highway Engineering (JTG E20-2005) and Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering (JTG E20-2011). The test results show that the technical performances of the selected raw materials are all qualified for the specification requirements.
