Abstract

Concrete waste is a waste material that is difficult to dispose of. The success of the use of concrete waste as road surface embankment material is also not yet clear. According to several studies that have been researched, 3R practices and concepts have been recommended to manage materials and waste from construction works. This study was conducted to evaluate the success of using concrete waste as a road embankment material, in addition to recommending it as one of the methods of construction waste management. This study was conducted by using 3 types of material samples with different ratios of material mixtures. The first ratio is 100% use of coarse aggregate. The second ratio consists of 70% concrete waste and 30% coarse aggregate. The ratio of the last sample consists of 30% concrete waste and 70% coarse aggregate. All samples will be tested with 2 specific types of tests to determine the strength of the material, namely Los Angeles Abrasion and Aggregate Crushing. The results of both tests carried out were positive where each of the tested samples passed the minimum approval value that had been set. The findings of the analyzed study found that the use of mixed concrete waste is suitable to be used as embankment material. However, the results of this study only focused on the strength aspect of the material. There are several tests that need to be carried out to determine the suitability of using concrete waste as an embankment material in road construction, such as tests to assess aspects of durability and the material's response to weather and so on.
