Abstract

RAP (Reclaimed Asphalt Pavement) is the material of pavement waste which is taken directly from damaged asphalt pavement road. Its constituent material consist of asphalt and aggregate. Its asphalt tend already hard and brittle, while its aggregate tend already occurred degradation. One way of waste utilization is recycling RAP. Recycling RAP is an effort to fix problem about new aggregate limitation which is used continuously. Purposes of this research are knowing density and bearing capacity characteristic of RAP material and RAP aggregate using AC-WC (Asphalt Concrete-Wearing Course). This Research uses laboratory test method. The material of RAP is from Tegal, Jawa Tengah. Research is started with preparation of apparatus and material in Pavement Material UMS laboratory. The test of research are: RAP identity test, RAP physics test, density test, and CBR test. In density and CBR test, material RAP and aggregate RAP divide into three fraction: grain size > 10 mm, 5-10 mm, dan < 5 mm. Then doing density test to get maximum dry bulk density and optimum moisture content, and CBR test with variation hit 10 times, 35 times, and 65 times. Depend on analysis of density and CBR characteristic in RAP material using AC – WC gradation, in fact the test result of density and CBR indicate that RAP material and RAP aggregate which already engineered using AC-WC gradation can not be used to wearing course although the value of abrasion still in the specification. Asphalt condition and old RAP aggregate can decrease strength and bearing capacity, it should added new aggregate to get better strength and bearing capacity. It could be seen from the research was obtained value as follows: density test with modified proctor, maximum density of engineered RAP is 1,92 gr/cm3, optimum moisture content is 8,23 %, maximum density of engineered RAP aggregate is 2,01 gr/cm3, optimum moisture content is 7,24 %. The value of CBR RAP is 19,30 % while CBR value in RAP aggregate more bigger: 25,57 %.
