Abstract

Natural rubber asphalt modification is the result of the mixing of asphalt with natural rubber plus chemical additives of vulcanization (sulfur) that are mixed into one in a hot state. The addition of natural rubber makes the asphalt more elastic and able to withstand loads from heavier vehicles, more heat-resistant, and more adhesive to aggregates that make the road surface more resistant to cracks and holes. The research aims to analyze indirect tensile strength values in asphalt-modified natural rubber. The research method is a laboratory experimental study referring to SNI 6753:2015, with immersion variations of  ½ hour, 24 hours, 48 hours, and 72 hours. The results of the study were indirect tensile strength values at congestion for 12 hours, 24 hours, 48 hours, and 72 hours in a row of 459,752 KPa, 427,571 KPa, 379,771 KPa, and 379,971 KPa. The resulting tensile strength ratio for each variation is 100%, 92.98%, 82.59%, and 75.52%. The study concluded that the tensile strength ratio at submersion for ½ hours, 24 hours, and 48 hours meets the requirements of the AASTHO T-283 specification.
