Abstract
Reinforcement of sugar palm fibers in asphalt concrete mixtures to increase strength and flow index due to increased traffic loads and temperature effects in order to reduce the potential for permanent deformation. The purpose of this research is to assess the extent of the influence of jute fiber as a reinforcing material in enhancing the cohesive and tensile strength of asphalt concrete mixtures, particularly in response to temperature changes. This research was conducted using an experimental method in the laboratory, employing jute fiber based on an optimum percentage of 0.6%, with a length of 8 mm, and tested under various temperature conditions. The test results indicate that asphalt concrete mixture reinforced with jute fiber (DP) has a total deformation of 1.09 mm at a testing temperature of 40°C. Its deformation rate is 0.0033 mm/minute, which is smaller compared to the asphalt concrete mixture without jute fiber (TS) with a total deformation of 1.19 mm and a deformation rate of 0.0040 mm/minute at the same temperature. At 60°C, the asphalt concrete mixture with jute fiber (DP) shows a total deformation of 1.83 mm with a deformation rate of 0.0107 mm/minute, while without jute fiber, the total deformation is 2.00 mm with a deformation rate of 0.0113 mm/minute. In the results, the indirect tensile strength of the asphalt concrete mixture without using palm fiber was lower, the stiffness of the mixture was lower than that of using palm fiber and decreased linearly with increasing temperature.
