| Summary: | Over the past decade, dramatic increasing in truck traffic, heavier axle loads, various
environmental impacts and higher tire pressure had contributed to severe pavement
distortions. In Malaysia, permanent deformation (creep deformation) is a continuously
pavement distortion problems which caused by effect of temperature, successive stresses,
excessive high bitumen content from improper mix design and insufficient compaction
during roadway construction. In bituminous mix, fine aggregate's recent trend is using
mining sand. Comparison in term of performance towards creep deformation between
marine sand and mining sand as fine aggregate are key purpose for the study. For
experiments, aggregate gradation are done for coarse aggregate; granite, fine aggregate;
marine sand and mining sand as "well as filler; ordinary Portland cement. It is to
determine the percentages of material used for making Marshall Mix sample. After
conducting Marshall Mix design, stability tests is conducted upon each of sample to
determine the optimum bitumen content by plotting graph of stability, density and void in
mineral aggregate versus binder content. Dynamic creep test is performed to compare the
performance of both samples. The result revealed that marine sand reaching stages of
failures is twice as much compared with mining sand. It proves that usage of marine sand
in bituminous mix increased its resistance towards permanent deformation (creep
deformation). |
