  • Road infrastructure plays an important role as one of the driving wheels of economic growth and development so that during its service life, it can provide good comfort and safety with quality that must be met. One of the efforts to maintain the quality of the pavement structure is the selection and modification of the materials used. Utilization and renewal of waste in the road construction sector has become an important issue. One of the waste materials in road construction that has been developed is gypsum powder, because the content of lime (CaO) is quite high. Resilience modulus is one of the fundamental parameters used in determining the quality of the material used as well as a measure of the stiffness of the asphalt concrete mixture. This study aims to determine the characteristics of the mechanical properties or the resilience modulus of the HRS-WC LATASTON asphalt mixture using polymer modified asphalt with gypsum powder as a filler. Based on the results obtained, it is known that the addition of gypsum filler into the LATASTON asphalt mixture can reduce the value of the resilience modulus so that the stiffness in the mixture is reduced and can make the mixture more resistant to repeated loads
