Abstract

Roads in coastal areas often experience problems with sea water inundation, namely the phenomenon of tides and tides that often occur in coastal areas. If seawater seeps into the pavement layer, it will cause the asphalt concrete pavement to become more easily damaged. The aim of this research is to determine the characteristics and influence of seawater and freshwater immersion in AC-WC mixtures using coconut shell charcoal as filler. This study used variations in asphalt content of 4.5%, 5%, 5.5%, 6%, and 6.5% of the total aggregate weight. The filler material is coconut shell charcoal (CSC) with an asphalt content in the asphalt mixture of 20% by weight. The soaking time is 4, 8, 12, 16, 20, 24, 28 and 32 hours. This research will be carried out at the Transportation and Highway Laboratory, Faculty of Engineering, Tadulako University. The temporary hypothesis is that the amount of damage to the asphalt concrete mixture during immersion in fresh water and sea water is caused by the salt content in sea water which causes the aggregate bond of the asphalt concrete mixture to become very weak and decrease when immersed in sea water. sea water, so that the pores in the asphalt concrete mixture are completely submerged. Sea water is filled with more water. Therefore, asphalt concrete mixtures that are submerged in sea water have the potential to reduce their stability. The results of the research show that the characteristics of the Asphalt Concrete Wearing Course (AC-WC) hot asphalt mixture which was added with coconut shell charcoal with an Optimum Asphalt Content of 5.8% and the addition of 20% coconut shell charcoal increased the durability of the concrete. Asphalt Concrete Use Course (AC-WC).
