Abstract
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.
Highlights
The highway is the main transport infrastructure in Indonesia and the total road length is 523,974 kilometres
The test results were shown by correlation chart between asphalt content with stability, flow, void in mixture (VIM), void filled with bitumen (VFB), and void in mineral aggregate (VMA)
Recapitulation value from correlation charts between asphalt content with stability, flow, void in mixture (VIM), void filled with bitumen (VFB), and void in mineral aggregate (VMA) that fullfiled for standard of Asphalt Concrete Wearing Course (AC-WC) mixture is showed on Figure 4
Summary
The highway is the main transport infrastructure in Indonesia and the total road length is 523,974 kilometres. There are two types of road pavement construction in Indonesia. It was flexible pavement and rigid pavement. It takes alternative material to replace cement as filler material Such alternative materials are preferred in many areas where there are road construction projects. The organic material content is lost due to the weather and leaves the nickel and iron substances that form a layer of soil and harden like a stone. In Borneo, laterite stones are used as subbase pavement layer because the material is easy to obtain and the quality is strong. It is hoped that with the results of this test the use of laterite stone can be used as an alternative to more expensive cement replacement
