Abstract

ABSTRACT This research is part of a long-term study in an effort to discover a kind of asphalt concrete mix that is both economical and highly durable at up to 600 celsius under flood water submersion. The research is conducted by testing the dynamic stability of hot mix asphalt concrete as to simulate vehicle wheel load on a flexible road pavement. The tested mix utilizes portland cement and stone dust as the filler aggregate, as well as soft-gradation stone ash bina marga 2010 with pertamina asphalt, asphalt concrete mix with retona asphalt, and asphalt concrete mix with superpave-gradation aggregate. All those mixes undergo the marshall stability test as well as residual stability and refusal density tests beforehand to achieve the most optimum composition. The marshall stability test is conducted with different submersion times, ranging from 24, 72 to 120 hours, at temperatures ranging from 300, 380 to 600 celsius. The dynamic stability of the mixes is tested by a wheel-tracking device at 300 and 600 celsius. The data is analyzed through the regression analysis method. After treatment, results showed that the mix of bina marga fine gradation with stone dust filler and retona asphalt 55has highest dynamic stability with lowest rate of deformation.

Abstract

Roads with flexible pavements whose surface layer consists of asphalt concrete have a high likelihood to get deteriorate due to frequent submersion caused by floods. This research aims to attain an economical asphalt concrete mix with high durability to submersion under the influence of high temperature. Performance is improved by making the asphalt concrete mix resistant to temperature changes through adding mineral water bottle wastes into asphalt until the optimum characteristics are attained. The filler aggregate used is stone ash. Research is conducted on the asphalt concrete mixture that submerged for 24.72 and 120 hours at 300, 380, and 500 celsius. Stability, flow, marshall quotient and pore contents are all tested by the marshall method. . Determination of the best mix with soaking time and temperature variation is done by the regression analysis method. Keywords: aggregate filer, asphalt concrete, mineral water bottle waste, submersion, stability, temperature.
