Abstract

The foundation on the road pavement plays a very important role in road construction because it is the fulcrum for transmitting and spreading the load to the construction section below it. In this study, the addition of waste teak sawdust as a filler material in the Asphalt Treated Base (ATB) mixture was carried out. The purpose of this study was to determine the feasibility of teak sawdust as a filler material in ATB and to analyze the percentage of the optimum value of the variation in the composition of teak powder as a filler material in the ATB mixture. This research was conducted with an experimental study approach in the laboratory to obtain the data needed for analysis. This research test guide uses the AASHTO (The American Association of State Highway and Transportation Officials) standards, BS (British Standard), and ATB (Asphalt Treated Base) specifications using the 2018 Highways Public Works Department guidelines. Analysis of test specimens includes analysis of aggregate strength. on impact, flatness index, angularity number, aggregate density, sieve analysis of fine and coarse aggregate, specific gravity and absorption of fine aggregate, specific gravity and absorption of coarse aggregate and aggregate wear using the Los Angeles tool. Testing of asphalt specimens includes inspection of penetration of bituminous materials, examination of flash and burn points, examination of softening points of asphalt and tar, ductility of bitumen materials, examination of specific gravity of hard and tar bitumen, and weight reduction of asphalt oil.testing Marshall includes stability, flow, VIM, VMA, MQ, VFA, and density. In view of the consequences of the examination, the outcomes acquired that teak wood powder can be supposed to be reasonable as a filler material in the ATB combination. The rate worth of the ideal sawdust content (SKO) in the ATB combination is 0.27% at the ideal black-top substance of 5.35% with the marshall test boundary worth of SKO steadiness of 1084.33 kg, stream 3.46mm, VIM 4.54%, VMA 16 .71%, MQ 312kg/mm, and VFA 72.81%. The aftereffects of the marshall test boundaries are still inside the base and greatest necessities indicated in the 2018 DPU Bina Marga Specifications for East Java Province. The SKO inundation record is 76.08%, so for this situation the ATB blend meets the necessities for the 2018 DPU Bina Marga Specifications for East Java Province which shows Marshall dependability worth of something like 800 kg and a drenching file of no less than 75%.
