Abstract

Roads are essential land transportation infrastructure; therefore, the quality of pavement must be maintained to ensure optimal performance and service life. One approach to improving the quality of flexible pavement in the Asphalt Concrete-Wearing Course (AC-WC) layer is by utilizing alternative materials as filler. This study investigates the effect of adding bamboo ash as an additional filler in AC-WC mixtures with PG 76 asphalt on Bulk Density and Marshall Stability. Bamboo ash contains silica (SiO₂) and exhibits pozzolanic properties that have the potential to enhance mixture performance. The bamboo ash content variations used were 0%, 0.5%, 1.0%, 1.5%, and 2.0% by total aggregate weight. Testing was conducted using the Marshall Test method in accordance with the 2018 Bina Marga General Specifications, Revision 2. The results showed that adding 1.0% bamboo ash produced the highest Bulk Density value of 2.310 g/cc, while the highest Marshall Stability value was obtained at 0.5% with 1,168.3 kg. All mixture variations achieved residual Marshall Stability values above the minimum requirement (≥90%), with the highest value of 91.47% recorded at 0.5%. Based on the balance between density and stability, the optimal bamboo ash content as an additional filler in AC-WC PG 76 is in the range of 0.5%–1.0%..Keywords: PG 76 asphalt, AC-WC, bamboo ash, filler, stability, density.

Abstract

This research is an experimental study aimed at investigating the effect of bamboo ash filler on the characteristics of Asphalt Concrete-Binder Course (AC-BC) using PG 76 hard asphalt. The variations of bamboo ash filler used were 0%, 0.5%, 1%, 1.5%, and 2% of the total filler weight. The tests conducted included the Marshall test to obtain stability, flow, VIM, VMA, VFB, and density parameters. The results indicate that the addition of bamboo ash as a filler affects the characteristics of the mixture. The stability values still meet the 2018 Bina Marga specifications (revision 3), although a decrease was observed at certain levels. Bulk density fluctuated with the addition of filler, while VIM, VMA, and VFB values changed according to the bamboo ash content. Overall, bamboo ash can be considered as an alternative filler in AC-BC mixtures, provided that the optimum content is maintained to avoid reducing the mixture’s performanceKeywords: filler, bamboo ash, AC-BC, PG 76 asphalt, Marshall

Abstract

Highways are an essential land transportation infrastructure, and the quality of pavement must be maintained to ensure performance and service life. One effort to improve the quality of flexible pavement on the Asphalt Concrete-Wearing Course (AC-WC) layer is by utilizing alternative materials as filler. This study examines the effect of adding bamboo ash as an additional filler in AC-WC mixtures with PG 76 asphalt on flexibility (flow) and durability (Marshall Retained Stability). Bamboo ash contains silica (SiO₂) and exhibits pozzolanic properties, which have the potential to enhance mixture performance. The bamboo ash content variations used were 0%, 0.5%, 1.0%, 1.5%, and 2.0% by the total aggregate weight, with testing conducted using the Marshall Test method. The results showed that the addition of 0.5% bamboo ash increased the flow value from 3.32 mm to 3.52 mm, while further additions above this level did not result in additional flexibility improvement. All mixture variations had Marshall Retained Stability values above the minimum requirement of PU Bina Marga 2018 Revision 2 (≥90%), with the highest value recorded at 0.5% (91.47%). Based on the balance between flexibility and durability, the optimal bamboo ash filler content for AC-WC PG 76 is 0.5%.Keywords : AC-WC, bamboo ash, PG 76 asphalt, flexibility, durability, Marshall Test.
