    Abstract

    The problem of shortages of normally acceptable materials can be alleviated by using low- and marginal-quality materials through selective use of stabilization. In areas where coal is prevalent coke-oven tar, modified with small quantities of polyvinyl chloride (PVC), can be mixed with sand to produce good paving material. Static and dynamic tests performed on PVC tar-sand mixtures show that the addition of PVC produces vast improvements in the Marshall properties and the resistance to permanent deformation, with only marginal influence on the compatibility. Mix design based on repeated loading tests at various temperatures suggests that the addition of PVC reduces the optimum binder content.
