Abstract:

In order to obtain new products or to use wastes as additive materials, intensive studies are performed on the usage and evaluation of waste materials in flexible pavement. The idea of reuse these materials with recycling reduces the use of limited sources of nature, prevents the destruction of the environment, increases efficiency in production, and minimizes the environmental problems that may occur as a result of waste storage. In this study, the evaluation of marble wastes usage in flexible pavement has been mentioned. Traditional bitumen and aggregate tests and in order to determine the performance characteristics of the bituminous mixture Marshall stability and flow tests have been performed. The modified Lottman test (AASHTO T283) has been applied on the specimens to determine the resistance on water-induced damages of the bituminous mixture specimens prepared with calcite based marble waste. The results that obtained have been compared with the Technical Specification of Highway (KTŞ). According to obtained, the physical properties of calcite-based marble waste aggregates as well as the stability and flow values of bituminous mixture have been found to be within the specification limits. It has been determined that the bituminous mixtures prepared with the hydrated lime additive increase the resistance on water-induced damages. Calcite-based marble waste aggregate is thought to be used as an alternative to limestone aggregate on medium and low volume traffic roads.
