Abstract
Waste glass is one of the waste materials that takes millions of years to decompose. One of alternative to processing waste glass apart from being recycled is to use it as material for flexible pavements. Waste glass that has been broken can be used as a substitute for fine aggregate asphalt mixture. The research was carried out with several tests, such as characteristics of the glass material and characteristics of the asphalt mixture using the absolute density method. Variations of glass material used as a substitute for fine aggregate are 0%,10%,20%, and 30%. The results showed that the use of 10% glass material as a substitute for fine aggregate in flexible pavement increased on the variable of density, flow, low asphalt content, and marshall immersion.
