This study aims to determine the effect of the Rice Husk ash as additive into bitumen 60/70 penetration of the bitumen characteristics, and determine the performance of a mix of -Wearing Course Asphalt Concrete (AC-WC) using bitumen with added Rice Husk Ash.This research, using the Marshall method that used in some variation of Rice Husk Ash content and asphalt content. Variations are used for grade Rice Husk Ash is 4%, 6%, and 8% by weight of bitumen and asphalt content 4%, 4.5%, 5%, 5.5%, and 6%.These results indicate that the physical addition of Rice Husk Ash making asphalt becomes brittle and adhesiveness decreases can be seen from the decline in value of 1.17% asphalt penetration at levels of 0% to 8%. Judging from the test results obtained that Marshall Stability value decreased by 28.57% of the value of the highest stability.
Forming sheet plastic into various new shapes and applications, this plastic is adjusted to the design we want with the help of heat, pressure and molding. The purpose of this study was to determine the energy and heat value released by PVC material with variations in heating and cooling temperatures in the forming unit,to determine the effect of PVC process temperature on thermal properties with DSC tools and to determine the effect of PVC process temperature on functional groups using FTIR tools.The calculation results show that the heat released by the A.1 material is 1,740 Watt and A.2 is 1,938 Watt. The energy received by the cooling water in the 30th minute on specimen A.1 is 5.571 Watt and A.2 is 14,857 Watt with each temperature increase of 0.5℃. The results of the DSC test samples A.1 (defective) and A.2 (good) show that the melting temperature of the two is almost the same, which is around 78oC but there is a difference in Tg (temperature glass) of 0.013 J/goC faster than the A.2 test specimen 115oC (Very nice). The results of the FTIR test samples A.1 (disabled), A.2 (good) showed the highest difference in wavelength up to 8.4% at the wave values of 3749.77cm-1 and 3740.90cm-1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
