This study is basic experiment which prevents indiscriminate reclamation and recycles the wasted tire in order to solve environmental pollution according to generation rate of the wasted tire from recently industrial development. By applying as the substitute material of the lightweight aggregate among the constructional materials in order to evaluate the lightness of the wasted tire chip and suggest the recycling plan of the wasted tire chip. The prior experiment did the replacement ratio of the wasted tire with 20%, 40%, 60%, 80%, 100%, etc. and made a study on the strength and density properties. Based on the prior experiment of wasted tire, the replacement ratio was fixed at 15, 20, 25%, particle size of wasted tire was fixed at 0.2, 0.8, 1~2, 3~5, 5~7(mm). As a result, it is supposed that the best replacement ratio and particle size are 15% and 1~2mm, respectively.

In this study, wasted stone powders (WSP) obtained from sludge and Wasted Tire Chips (WTC) as fillers have been used to formulate polymer hybrid composites based on Unsaturated Polyester (UPE) resin. To further enhance not only the interfacial bond between the inorganic filler and the polymer matrix, but also the filler dispersion by wetting the particulate surfaces to uniformly spread the resin during the mixing, silane coupling agent[${\gamma}$-methacryloxy propyl trimethoxy silane (${\gamma}$-MPS)] was used. The influences of organic recycled fillers contents and the concentrations of coupling agent in polymer hybrid composite formulations have been investigated from a mechanical and microstructural point o view through Mercury Porosimeter and SEM.
