Abstract :
Road construction in Indonesia mostly use this type of road pavement malleable (flexible pavement). In one of the flexible pavement hot mix asphalt that is often used as a road surface layer is a mixture of Asphalt-Concrete Wearing Course (AC-WC) is often called asphalt concrete (AC Laston-WC). In order for a mix function normally then there are some of the key aspects that make the mixture works well, it should be noted the level of stability, because stability is the ability to receive a load of asphalt to happen kelelehan (flow) is expressed in kilo gram. Flow (flow) is a state change in the form of an asphalt mixture that occurs as a result of a load, expressed in mm. Based on the results of research and discussion is done, it can be concluded that: The effect of the use of a spherical aggregate makes the stability of asphalt concrete decreases and the value of vim increases, VMA decreases, VFA decreased, Density decreases, the value of flow increases so that the porsentase cobblestone 20% and 30 % value of stability is getting smaller and are not included in the specification suggested by DGH 2010 revision III, while the cobblestone porsentase 0% and 10% goes to the standards suggested by DGH 2010 revision III. It is advisable to use a percentage rounded stones in the manufacture of asphalt concrete should not exceed 10%, or a maximum of 10%
