THE CHARACTERISTICS OF BITUMEN WITH PLASTIC AS <br /> AN ADDITIVE AND ITS PERFORMANCE ON HRA <br /> MIXTURES, Yolly Detra Asrar, 2001, Program Magister Pascasaijana <br /> Teknik Sipil Pengutamaan Rekayasa Transportasi, Institut Teknologi <br /> Bandung. <br /> High temperature of road pavement, high rainfall and traffic loading <br /> are some several reasons caused some defects on asphaltic pavement in <br /> Indonesia. Many attempts have been done in reducing these tendency of <br /> defects and one ofthem is by introducing an additive agent in bitumen to <br /> change its physical properties especially in temperature susceptibility <br /> and stripping, and associated with aggregate to make a better asphaltic <br /> mixture suited to high temperature and heavy rainfall condition like in <br /> Indonesia. <br /> In this study, the use ofplastic as an additive in bituminous material <br /> agent is expected to change the physical properties of bitumen and <br /> improve mix stability and its resistance to deformation. The results show <br /> that the addition of 0% to 5% of plastic into the bitumen lead to a <br /> reduction in penetration value from 74,9 to 66,6 Although additional of <br /> plastic reduce softening point of bitumen, addition of I % to 5% plastic <br /> cause a relative small changes ofmixing and compaction temperatures <br /> The result ofMarshall test shown that the addition ofplastic up to 3% <br /> in bitumen, improves the stability, density, CAD and Marshall Quotient <br /> of HRA mixture. In line with the addition of plastic content in bitumen, <br /> permanent deformation ofmix resulted from the wheel tracking test are <br /> decreased and caused an improvement in dynamic stability of mix. In <br /> general, the results ofthis study shown that the addition of2% to 3% of <br /> plastic to bitumen gives a better influence to asphalt mix characteristic.
