The highway is the main transportation infrastructure in Indonesia. Most of the highway pavement construction in Indonesia is flexible pavement. The filler commonly used in hot mixture asphalt is Portland Cement. Along with the issue of sustainable development and utilization of local materials, fillers are often replaced with cheaper and easily available materials. One material that can be used as a filler, cheaper and easily available is Laterite.
The experiment was proposed to find out whether laterite could be used as filler material on Asphalt Concrete Wearing Course (AC-WC). The method and technical specification of experiment referred to Asphalt Pavement Specification, that published by Public Work Ministry of Indonesia. The experiment had another objective. The experiment would be examine whether laterite percentage variation on filler material that mixed with Portland Cement, would effect on Marshall Stability value. The filler material was a mixture of laterite and Portland Cement, which the proportion of each were 0:100, 50:50, and 100:0. Each proportion of filler material compacted with 75 and 400 blows. There were 3 samples of each combination of the proportions of the filler material. The total number of specimens were 18. Furthermore, the Marshall stability value of each specimen would be tested using ANOVA test. And ANOVA test used Software Minitab 16.
The experiment result showed, Marshall Stability was greater than 800 kilograms as asphalt concrete wearing course (AC-WC) specification requirement. Analysis of Variance (ANOVA) test results using Minitab 16 software showed no difference in Marshall stability value on all specimens. Because, P-value of Laterite and compaction combination were less than 0.05.
