Abstract

The objective of this research study is to compare the performance between normal asphalt concrete and glass asphalt (glassphalt) concrete by finding the optimum bitumen content of each sample. This is to prove the ability of the glass as a replacement to the normal aggregates. Glass cu11et, which is processed waste, can be reused as aggregates in order to reduce the depletion of source rocks. However, anti-stripping agent, which is hydrated lime, must be used to avoid the slipping between glasses surface. Sieve analysis had been carried out for both sample to determine the exact portion of coarse aggregates, fine aggregates and filler For the glassphalt sample, 10% of glass is being used for the test. The size of the glass sample for this research is below 3 35 mm. The Marshall Test then was carried out to determine the optimum bitumen content for the specific samples It is found out that for the normal sample, the optimum content is 6% while for glassphalt concrete is 6 5% The stability of the glassphalt concrete is slightly higher than normal aggregates. This research can be improved in the future by using various sizes of the glass. Glass might not give a great improvement on the stability of the asphaltic concrete, but it will save the environment by giving adequate strengths needed in asphaltic concrete.
