STRUCTURAL PERFORMANCE STUDY OF ASPHALT PAVEMENT IN WET-HEAT DISTRICT OF CHINA

This paper proposes a design procedure for structural strength of the asphalt pavement. A design example is presented. Through deflection monitoring of the reinforcing structural layers and comparison with control deflection values, it has been demonstrated that the structural layers meet the requirements of design strength as anticipated. Laboratory tests show that the strength, stiffness, and thermostability of ashplat concrete course will be satisfactory for heavy traffic. The main aggregates of the asphalt surface course should be a certain amount, say 50%, of hard sandstone aggregate added to enhance the coefficienct of friction of the pavement and also to maintain longer service life.
