KINERJA CAMPURAN SMA DENGAN MENGGUNAKAN PASIR PANTAI INDRAYANTI SEBAGAI PENGGANTI AGREGAT HALUS

Abstract

Split Mastic Asphalt (SMA) mixture is one of the favored materials for flexible pavement in Indonesia. Due to the limitation of fine aggregate products from stone crusher, therefore, an alternative sand beach is used. This paper presents the results of determining the influence of the use of coastal sand as fine aggregate substitution on the Split mastic asphalt (SMA). This research has four phases, first testing of aggregate and asphalt properties, then the determination of optimum asphalt content 0%, 25%, 50%, 75%, and 100%. The next step was testing Marshall, Immersion, Indirect Tensile Strength, and Cantabro loss. The results showed that the use of Indrayanti's sand beach as a substituted fine aggregate on the Split Mastic Asphalt 0/11 mixture meets the standard. Based on Marshall's test stability and flexibility of all the mixture was higher, the Bina Marga specification. Indirect Tensile Strength increase in each addition of Indrayanti's sand beach. Cantabro Loss and Index Retained Strength on all specimens of Indrayanti's sand beach qualify Bina Marga standard.
