Analysis of mixed stiffness modulus of different asphalt levels for AC–BC pavement layer with pertamina 60/70 asphalt and 60/70 esso asphalt material

Abstract

Abstract Asphalt/bitumen is a brownies black material, is viscous so it will soften and melt when it gets enough heating. In general, asphalt is obtained from petroleum refining. Pavement construction in Indonesia, both road rehabilitation project, maintenance and construction of roads, generally. Pertamina 60/70 asphalt is used as a binder for the asphalt mixture. Apart from pertamina asphalt, there are several types of asphalt that ore often used in projects in Indonesia, one of which is esso 60/70 asphalt.Esso asphalt is a type of asphalt produced from foreign companies outside of Indonesia, so it is necessary to do a comparative research test on the Marshall Properties and the stiffness modulus of asphalt. The research was conducted to analyze the stress-strain relationship which show the stiffness and strength of the asphalt material by experimenting with several test objects using the Marshall tool. If the value of the stiffness modulus decreases, asphalt aging will occur which causes the pavement to crack easily when receiving heavy loads. The stiffness modulus analysis of the asphalt mixture is an analytic procedure for planning and evaluating the performance of asphalt mixture. Asphalt mixture is a material that is not perfectly elastic, so the use of the term modulus of elasticity (E) is not suitable, instead the term mixed stiffness modulus is used. The data needed is the value of the stiffness of the asphalt content mixture which was tested by the laboratory to obtain the stiffness modulus and asphalt content characteristic.
