This study aims to determine the effect of temperature on coefficient of tire grip on the cement track. This study uses artificial compound and compound the market as a comparison. The composition of the artificial compound consists of a mixture of raw rubber with chemicals that have not been vulcanized. Rubber used is natural rubber RSS and synthetic rubber SBR, while the chemicals used are plasticizers, fillers (fillers), anti-oxidants, accelerators, and other chemicals.
In the artificial compound rubber mixing with chemicals is done by using a two-roll mixing with temperature of ± 550C. The mixing process begins mix of natural and synthetic rubber so that it blends and soft, then mix the chemicals to converge ± 30 minutes. The next process of vulcanization by using a mold-pressed part to a temperature of 1600C for 15 minutes.
Based on the results of tests performed, the amount of temperature that is used greatly affect the grip coefficient of the tire. Tests on artificial compound with dry conditions resulted grip coefficient of 0,658 temperature 20oC, 0,633 temperature 30oC, 0,631 temperature 40oC, wet conditions resulted in 0,430 temperature 20oC, 0,455 temperature 30oC, 0,455 temperature 40oC. While in the market compound dry conditions produce a grip coefficient of 0,698 temperature 20oC, 0,688 temperature 30oC, 0,649 temperature 40oC and wet conditions resulted in 0,433 temperature 20oC, 0,460 temperature 30oC, 0,457 temperature 40oC. In testing the artificial compound shore A value of 68.333 and compounding market value of 60
