Abstract

Along with the times, people’s needs are also increasing. No exception is the need for road infrastructure, both in urban and rural areas. The road is an important access to carry out daily activities. One of the important processes that must be carried out in the design and formation of roads is the process of road paving. Paving roads are an important point in a development, especially in terms of infrastructure for transportation. Bangka Belitung has the potential for fine aggregate material in the form of kaolin sand and tin tailing sand which are waste from mining natural resources of tin and kaolin. In order to reduce the use of river sand as standard fine agregate, kaolin sand and tin tailing sand can be used as an innovation or alternative for replacement on river sand as standard fine aggregate materials in road pavement structure. Therefore, research was carried out to find out the characteristics of kaolin sand and tin tailing sand in the AC-WC (Asphalt Concrete Wearing Course), AC-BC (Asphalt Concrete Binder Course), and Hot Rolled Sheet-Wearing Course (HRS-WC). This study uses the Marshall Tests parameter. Based on Marshall test results, the best Optimum Asphalt Content of AC-WC mixture using kaolin sand is 5.73%, AC-WC mixture using tin tailing sand is 5.45% and AC-WC mixture using river sand is 5.7%. The Optimum Asphalt Content of AC-BC mixture using kaolin sand is 5.8%, AC-BC mixture using tin tailing sand is 5.6% and AC-BC mixture using river sand is 5.55%. Optimum Asphalt Content of HRS-WC using kaolin sand is 8.045%, HRS-WC mixture using tin tailing sand of 8.18% and HRS-WC using river sand is 7.965%. It can be concluded that the Optimum Asphalt Content of AC-WC mixture with the use of kaolin sand and river sand tends to be higher than the AC-WC mixture with the use of tin tailing sand. AC-BC mixture with the use of kaolin sand and tin tailing sand, the Optimum Asphalt Content tends to be more higher than the mixture of AC-BC using river sand. HRS-WC mixture with the use of kaolin sand and tin tailing sand, the Optimum Asphalt Content tends to be more than the mixture of HRS-WC with the use of river sand.
