Abstract

The materials commonly used as fillers in AC-WC road pavement mixtures are cement and fly ash, which are relatively expensive and in limited supply. Therefore, research is needed to use alternative materials as filler substitutes. One of the alternative materials is marlstone, which contains chemical compounds in the form of CaCO3. The purpose of this study was to determine the effect of marlstone in AC-WC mixtures on the Marshall value. The percentage variations of marlstone utilization as filler substitutes were 0%, 25%, 50%, 75%, and 100% of the total weight of the fly ash filler. This study used the Marshall test method which refers to the 2018 Bina Marga Specifications, Revision 2. In this study, the optimum asphalt content was 5.4%. The greater the percentage of filler used in the mixture, the VMA and VIM values increased, however, for the VFA parameter at variations of 0%, 25%, and 100% that met the 2018 Bina Marga Specifications, Revision 2. The stability values for the percentage of marl stone as a filler substitute ranging from the smallest to the largest were 2422.1 kg, 2396.195 kg, 2180.321 kg, 2167.369 kg and 1826.289 kg. Although there was a decrease in stability, it still met the established standards. The flow value in this study decreased and increased, but was still within the specification standards. In this study, the variation using marl stone filler did not meet the minimum requirements of the 2018 Bina Marga Specifications, Revision 2.
