Abstract
One of efforts for sustainability in Road Pavement Materials agenda is reducing virgin material in road pavement construction and increasing the use of waste materials as alternative materials in road pavement materials without reducing quality of pavement structure. The objective of this paper is to discuss the use of product waste materials from industry for road pavement construction in Indonesia. Waste materials used in this study as additive materials on road construction are Residium Catalytic Cracking 15 (RCC-15), lignin, slag and tailing. RCC15 addition showed an increase of soil bearing capacity and reduce the level of expansion on soil on composition of 2% RCC and 2% PCC, the addition of 4% lignin by weight of dry soil can increase the unsoaked CBR, the use 100% of slag will provide a better mix characteristic than the natural aggregate mixture and the addition of 45% tailing in mix gave good effect on stability of base and sub-base layer and Generally, test laboratory results showed that road construction containing waste materials have higher performance than conventional road construction.
