One effort to improve the performance of road pavement layers and the quality of asphalt mixes is through the modification of asphalt by polymeric materials addition. Latex is a polymer material that can be used and easily found in Indonesia, known as one of the world’s largest natural rubber producer countries. This study intended to improve the quality of Hot Rolled Sheet Wearing Course (HRS-WC) mixture by utilizing latex 1%, 2%, 3%, 4%, 5%, 6%, 7%, and 8% as a partial replacement of asphalt material through Marshall testing. From the test results, it can be summarized that the Optimum Asphalt Content (OAC) value of the HRS-WC mixture was 7%. Furthermore, the Optimum Latex Content (OLC) meeting the specifications was 1% with a Density value of 2.25, a VMA value of 19.68%, a VFA value of 76.78%, a VIM value of 4.57%, a stability value of 1766.44 kg, a Flow value of 3.14 mm, and MQ value of 629.01 kg/mm
