Abstract

The use of sea sand in construction work from an economic point of view does have advantages. One of them is increasing the income of the sea sand collectors who are spread throughout the area in Fakfak Regency. In addition, the potential availability of sea sand is quite large and is able to accommodate all types of concrete construction work in this area. This study aims to determine and analyze the use of sea sand in the AC-WC mixture of course by doing the Marshall test. This study uses variations in asphalt content of 5.0%, 5.5%, 6.0%, 6.5% and 7.0%, this study was carried out using Marshall testing in accordance with the general specifications of Bina Marga 2018. The results of the research conducted showed a relationship asphalt content and Marshall parameters such as stability value, VMA, density, MQ at an asphalt content of 5.0%-7.0%, meet the specifications of 1932 kg, 19.84%, 2.26 gr/cm3 and 1031 kg/mm. Values of VIM, VFWA and flow at 5.5% asphalt content are known to not meet the mix spasticity, namely 8.07%, 59.71% and 1.67 mm. Based on the Marshall parameter data, the Optimum Asphalt Content value is 6.5%.

从经济的角度来看，在建筑工作中使用海砂确实有好处。其中之一是增加分布在法克法克摄政地区的海砂收集者的收入。此外，海砂的潜在可用性相当大，能够容纳该地区所有类型的混凝土建筑工程。本研究旨在通过马歇尔试验确定和分析海砂在AC-WC混合料中的使用情况。本研究采用沥青含量为5.0%、5.5%、6.0%、6.5%和7.0%的变化，本研究是根据2018年比纳玛加的通用规范使用马歇尔测试进行的。研究结果表明，在沥青含量为5.0% ~ 7.0%时，稳定值、VMA、密度、MQ等马歇尔参数与沥青含量的关系为:1932 kg、19.84%、2.26 gr/cm3、1031 kg/mm。沥青掺量5.5%时的VIM、VFWA和流量值分别为8.07%、59.71%和1.67 mm，均不满足混合料的痉挛性。根据马歇尔参数数据，最佳沥青掺量为6.5%。
