Généralement, les ouvrages utilisent le sol autant qu’un élément de l’infrastructure qui transmet la charge globale de l’ouvrage vers des couches de sol suffisamment résistantes. © International Journal on Advanced Science Engineering Information Technology. The 1.5% Styrofoam Asphalt ratio having the value of Voids in the Mixture is 4%, the Void in Mineral Aggregate is 19.2%, the Void Filled with Asphalt is 80%, and the Marshall Quotient is 260 kg/mm. Asphalt mixture with the addition of Styrofoam as much as 1.5% has a maximum Stability above 1500 kg with optimum binder content is at 7.4%, and the value of Flow is above 3 mm. The value of Flow is also increases when compared with asphalt mixture without Styrofoam. Based on the research, it can be concluded that the use of asphalt with the addition of Styrofoam as much as 0.5%, 1%, and 1.5% by weight of asphalt in an HRS-Base mixture improves the Stability of the mixture. This study was conducted to determine the effect of Styrofoam on Hot Rolled Sheet-Base (HRS-Base) by varying the addition of Styrofoam in the mix. Styrofoam is one type of waste that has characteristics that are nearly equal to asphalt, which are soften when heated and harden when temperatures return to normal. In this research, Styrofoam is added to the HRS-Base type of pavement to investigate the Marshall Parameter of its pavement mixture. ![]()
