Laboratory Investigation of the Effect of “NICOFLOK” Polymer on the Compressive and Tensile Strength of Desert and Coastal Sand at the pavement Layers

Construction wastes can be found easily and are increasing by the developing of cities. Lack of sufficient knowledge and facilities for recycling these materials causes deposition of these materials and unfavorable scenes in suburban regions. Settlement of these materials makes some troubles for building constructions on them. Prevalence of disease, growing of vermin and also the low potential of these materials for raising plants are some of the problems which are the motivation for many scientific researches about recycling of these materials. In this study first brick, gypsum and cement contained wastes were collected and then 200 samples with 3, 6 and 12 percent of cement in 4 groups with different mixture of wastes were made. Compressive and indirect tensile strength tests and the test of durability against freezing and thawing were conducted to evaluate these materials to be used in stabilized base and subgrade layers. The results show that many mixtures of these materials have sufficient compressive strength and durability to be used in base and subgrade layers according to highway construction codes.
