Abstract
An Open Graded Friction Course is an open-graded asphalt mixture with a high percentage of coarse aggregates, almost uniform in size, resulting in a high percentage of air voids, usually 15 to 25 percent. The main benefits of the mix are improved safety by increasing the frictional properties of the pavement surface and allowing surface water to drain through the pavement. One of the disadvantages of an Open Graded Friction Course is less stability, and a large void makes the layer easy to strip. An additional material that promises to increase stability and durability is hydrated lime Therefore, this study aims, to investigate the effect of lime on Modificated Open Graded Friction Course with cellulose fiber and lime on stability and durability. The method used in the study is the Marshall Stability and particle loss test. The result shows that modification of the Open Graded Friction Course with cellulose fiber and lime increases stability, and decreases particle loss
