Abstract

Indonesia's population is increasing exponentially, causing increased mobility. Therefore, it is necessary to increase the quantity and quality of roads to meet community needs. In Indonesia, hot mix asphalt, also known as hot mix, is the most common type of mix. Asphalt Concrete (AC) consists of asphalt as an adhesive, coarse aggregate and fine aggregate, and filler as a filling material, according to the 2010 BM specifications. All materials used in this research refer to the general specifications issued by the Directorate General of Highways in 2010 Revision 3, and the Marshall test will be carried out by replacing the Portland cement filler with Wood Ash in the Laston mixture. The asphalt used has a penetration of 60/70 and is used with compaction variations of 40, 50, 60 and 80 impacts. The research using wood asphalt as a filler showed a Marshall stability of 840.72 kg, a Marshall coefficient of 3.49 kN/mm, a film thickness of 6.64 μm, and an air mist volume of 4.59%.

Abstract

The MT Haryono highway in Malang City is a type 4/2 UD collector road which connects various places in both the economic and educational sectors in Malang City. The large number of activities that occur on this road result in a buildup of vehicles and high side obstacles, causing traffic jams during rush hours. To overcome this problem, an analytical study using the MKJI 1997 method is needed. The results of the analysis are the value of the degree of saturation for current road conditions >0.80, namely 0.94 at the service level (E) of unstable flow. Therefore, 2 (two) alternatives are given to reduce the DS value, the second alternative is recommended, namely changing the road type to a one-way road so that a DS value of 0.67 is obtained at a stable flow service level (C). Analysis of the performance of the MT Haryono Road section after alternative improvements for the next 5 years is still at a stable service level, with a DS value in 2028 of 0.76 at service level (D).
