Index Retained Strength Mixture of Fine Stone Mastic Asphalt using Concrete Waste Aggregate

Concrete waste that is left untreated will cause its own problems for the environment. The purpose of this study is to analyze the Retained Strength Index for Stone Mastic Asphalt mixtures that use concrete construction demolition waste aggregate. The test method used is the Marshall method. Aggregate test results from waste concrete meet the requirements for use as a fine SMA material. This can be seen from the results of the aggregate resistance test and the specific gravity obtained. The results of the Stability and Flow tests as well as the VIM and VMA analysis show that the values meet the Bina Marga standards. The results of the Marshall Immersion test show that the Retained Strength Index Value is 92.71%. Based on these values, it can be concluded that road pavements using concrete waste aggregate in a mixture of fine Stone Matrix Asphalt (SMA) can withstand temperature and the length of time they are submerged in water.
