MODEL PAVEMENT ASPHALT ROADS BY USE WASTE SPON AND WASTE TIRE

Indonesia is the world's biggest producer of asphalt in which raw materials are contained in the soil of the hill and the mountain located on the island of a button. Highway construction is one of the priority sectors of development. The impact of this activity is the growing need for natural asphalt and aggregate, both aggregate coarse and fine aggregates. Asphalt demand of 600,000 tons per year, usually asphalts obtained from the import because Indonesia only sells in the form of raw bitumen and asphalt to get ready so Indonesia bought from other countries, it clearly results in reduced foreign exchange and availability. For the various kinds of innovations made by the manufacturer of asphalt, one with a modified bitumen. The Method used is to mix pure bitumen pen 60/70 with sponge rubber waste and waste the old tires.Based on the research results, the mixed asphalt material sponge waste and waste tires in the composition of 2%, 4%, 6% are not in accordance with the criteria of modified bitumen according to the specification bina marga. Penetrate the sponge Waste and waste tires in the composition of 6% with a value of 56mm and 58mm. Waste ductility Spon composition of 2% with a value of 104, for waste tires in the composition of 2% 4% with a value of 140 and 120. Test Solubility Waste sponge with the composition 6% primarily to the value of 99.904%. Test softening point sponge waste composition 6% with a value of 54.4oC and waste tires in the composition of 6% with a value of 54° C. But after the return value of the elasticity of the sponge waste and waste tires in the composition of 2%, 4%, 6% the test results do not meet the specifications bina marga
