PENGARUH LIMBAH BATU MARMER SEBAGAI PENGGANTI AGREGAT KASAR 10/10

Studi kasus lapisan ATB ( Asphalt Treated Base) terhadap nilai karakteristik

Abstract

The composition of the pavement material greatly determines the quality of the asphalt pavement mixture, considering that marble waste from marble stone processing in Gamping Village, Campurdarat District, Tulungagung Regency is not used as a building material, therefore this study aims to determine whether marble waste is suitable for use as a substitute for mountain rock aggregates. or black stone as a mixture of asphalt pavement. And what percentage of the recommended amount of marble waste is used. Based on previous research, it is known that marble stone waste has characteristics as a substitute for coarse aggregate, this study aims to determine the content of marble stone waste as a substitute for coarse aggregate 10/10 in the ATB layer, by examining its levels. marble waste 25%, 50%, 75% and 100%. From the results of the research conducted, it is found that: (1) Aggregates meet specifications and are suitable for use as a mixture of road pavements. (2) Marble stone waste as a material from coarse aggregate 10/10 on the ATB layer has an effect or gives a significant difference. This can be seen from the test results, where Fcount> Ftable. The stability value at 0% marble content was 1048.56 kg and at 100% marble content was 938.32 kg. the expected criteria value in the mix of limits set by the 2018 Highways Agency such as the value of stability, flow, VIM, VMA, VFA and MQ.
