Abstract


The compressive and shear strength of mechanical behavior of asphalt concrete is related to resistance against plastic deformation, which reduces the rutting value. The tensile strength is related to adhesion with aggregates. As tensile strength increases, the adhesion between the mastic and aggregate increases, this is important to resisting cracking and dipping stripping. This study uses cement as a modifier for emulsified asphalt, which is mixed to form cement-asphalt mastic. As the strength of asphalt concrete is directly proportional to strength of the asphalt mastic, this study examines the mechanical strength properties of cement-asphalt mastic as a foundation for further research of cement-asphalt concrete. In this study, maximum values over 28 days of aging for various mechanical strengths of cement-asphalt mastic are 13400kPa compressive strength, 1200kPa tensile strength and 1670kPa shear strength.
