Effects of Dammar as the partial substitution of bitumen in HMA AC-WC containing Buton Asphalt

Petroleum asphalt is the residue of fossil fuel distillation. The flexible pavement material generally uses petroleum asphalt. The world’s need for bitumen increases from year to year to pavement materials. Meanwhile, the availability of bitumen as a non-renewable resource is limited. To meet the wo...

Description
Summary:Petroleum asphalt is the residue of fossil fuel distillation. The flexible pavement material generally uses petroleum asphalt. The world’s need for bitumen increases from year to year to pavement materials. Meanwhile, the availability of bitumen as a non-renewable resource is limited. To meet the world’s need for bitumen in the future, the utilization of natural polymers, such as a dammar, can be the best solution. This study aims to analyze the influence of dammar on the Marshall stability of HMA AC-WC containing Buton Granular Asphalt (BGA). This study was carried by using Marshall testing on the Asphalt Concrete Wearing Courses (AC-WC) containing Buton asphalt of 10%. Bitumen content is in all specimens amount 6,3%, bitumen content of BGA 50/30 is 22,48%, and the variation of dammar content is as the substitution of bitumen of 2.5-10%. Before mixing all material, it was first conducted the mixing of dammar and penetration at the temperature of 90°C to get a modified asphalt. The use of 10% dammar in asphalt mixtures meets the requirements of Bina Marga specifications. Utilization of Dammar content of 10% with BGA content of 10% can substitute petroleum asphalt by 45.68%.
