The road construction carried out at present faced with the improvement of the quality and cost of development. The development of research on material substitutes highway construction can be a solution to improve the quality of road construction materials. The aim of this research is to know the effect of the use of molasses as a partial replacement for Laston asphalt AC-BC and AC-WC.This study uses a 60/70 penetration bitumen, the bitumen content variation of 5%, 5.5%, 6%, 6.5% and 7% and variation levels of molasses as a partial replacement of asphalt 4%, 8%, and 12%. The combined aggregate grading is based on the specifications required by the 2010 revision of Highways 3, in order to obtain the composition of the asphalt mixture AC-BC and AC-WC using coarse aggregate to ACBC 50%, Fine aggregate 44.2% and filler 5.8%, for coarse aggregate AC-WC 41%, Fine aggregate 52.1%, and filler 6.9%, Testing was conducted by Marshall.The result of research shows that use of molasses as a partial replacement of asphalt on Laston AC-BC value Marshall test highest levels of molasses 4%, the value of Marshall test such as the value of VFB, stability and flow is lower, while the value of VIM, VMA and MQ tend to be higher, compared to with the normal mix with OBC 6%. In the Laston AC-WC with the use of molasses as a partial replacement of asphalt, the value of Marshall test highest levels of molasses 4%, the value of Marshall test such as the value of VFB, stability and MQ lower, while the value of Flow, VIM and VMA tend to be higher, compared to with the normal mix with OBC 6%
