One of pavement types generally used in Indonesia is Hot Rolled Sheet (HRS) type. This study used Coconut Shell Charcoal containing activated carbon to make test specimen mixture. The aim of this research was to investigate the effects of Hot Rolled Sheet WC mixture by adding coconut shell charcoal powder. Qualitative method was employed in this research for analyzing the result of marshal test. The researcher gave additional coconut shell charcoal powder in several levels, such as 0%, 2%, 4%, 6%, 8%, and 10%. Testing the coconut shell charcoal powder mixture got the optimum result by the content 4% having the highest stability value 1191.10 kilograms, marshal quotient value 374.17 kg/mm, VIM value 4.34%, and VMA value 18.65%. Accordingly, the stability, VM, and VMA increased and were in accordance with the general specification of Bina Marga 2018, but the values of flow and VFB decreased along with the coconut shell charcoal powder addition respectively by 3.18 and VFB 76.70%. Overall, the additional content 4% has met the general specification of Bina Marga 2018.
