Pengaruh Latek pada Kepekaan Terhadap Temperatur Bahan Pengikat Aspal

Abstract

Natural rubber (latex) is an additive that could be expected to enhance the physical properties of an asphalt mixtrure, particular its temperature susceptibility bitumen in the form of latex-bitumen in road construction merits consideration. The objectives of the research were to in investigate the effect of latex on the temperature susceptibility. Bitumen used was 60/70-penetration grade and the latex was Dry Rubber Content 60. The results of tests in binders containing 0%, 2%, 4%, and 6% by weight of bitumen indicated that penetration index increases with increase in latex content, indicating a reduction in temperature susceptibility.
