Abstract

Buton asphalt is an alternative material for road surfacing from Indonesia. Cold paving hot mix asbuton (CPHMA) is one of the buton asphalt technologies that has great potential as an alternative to conventional asphalt pavement; however, it still possesses several limitations that remain the focus of ongoing scientific research.

The problem solved by this study is the improvement in CPHMA performance as the storage duration of the mixture increases, which is a controlling factor in conventional CPHMA products.

The results show that the use of candlenut oil modifier improves the CPHMA performance. The study is focused on the CPHMA performance with variations in the storage duration of the ready-mix.

This study shows that the highest resistance from fatigue and creep tests was obtained at a storage duration of 21 days. There was an anomaly in the stiffness modulus test, where the highest resistance was obtained from the 7-day sample. However, this value is somewhat questionable because the two samples used yielded a high standard deviation. Therefore, if to disregard the results from this sample, the sample with the highest resistance is the same as in the fatigue and creep tests.

The most distinctive feature of these results is the discovery of increased CPHMA resistance to dynamic loads that increases with storage duration. This contradicts the CPHMA product manufactured by the factory.

Regarding the scope of practical use, the results obtained in this study indicate that CPHMA modified with candlenut oil is very suitable for low-volume pavement applications, especially in areas that do not have an Asphalt Mixing Plant. Certain conditions of use, field application is ideally carried out during dry weather to effectively facilitate the evaporation of volatile bio-modifiers, ensuring the mixture reaches the desired stiffness as shown in the laboratory results
