n Ethiopia, every year, various projects on road repair, upgrading, new road construction, andrnroutine maintenance projects are undertaken, all of which rely on the usage of natural andrnindustrial resources. Reclaimed asphalt pavement material (RAP), the usage of RAP in Ethiopiarnis very limited , due to lack of clear standard and recommendations on how to use asphaltrnpavement wastes. Reclaimed asphalt pavement has advantages in terms of environmentalrnbenefits, cost savings, land fill, and, but it also has drawbacks such as ductility loss and harshrnmixtures when it is optimized. This research studies the effect of RAP on HMA with binderrntreated with molasses. The marshal mix method was used to create hot mix asphalt in thernlabratory. The volumetric test, stability, flow, moisture susceptibility, and rutting tests werernperformed on four different Reclaimed asphalt pavement contents (10, 20, 30, and 40%) HMArnwith a 3% molasses modified binder. Based on this study, when compared to the control mix, allrnof the modified mixes performed better in the tests undertaken for this study. When compared tornother RAP and molasses-modified mixes, the RAP and molasses-modified mixes had betterrnmoisture resistance and lower rut depth. The RAP and molasses modified mixes performed betterrnin terms of stability, flow, and volumetric qualities when compared to the other mixes, howeverrnbecause the RAP percentages utilized were 10%, 20%, 30%, and 40%, these attributes improvedrnon the higher RAP (30 & 40) percentages this may be due to the softening effect of molasses.rnMixes with RAP and molasses showed better resistance for moisture and lower rut depth, butrnmore studies should be conducted for different molasses and RAP contents with morernperformances tests to have more reliable data
