Impact of Plastic Waste on The Volumetric Characteristics and Resilient Modulus of Asphalt Concrete

Recently, the use of plastic in many products has led to a huge amount waste, which is typically difficult treat and expensive recycle. This problem been considered by researchers environmental organizations as requiring serious considerations about recycling reusing waste different fields, such asphalt mixtures. In this paper, aggregate passing 4.75-mm sieve was replaced 5, 7, 9, 11% bottles used for drinking purposes. The dry method adopted work, changes mixture’s volumetric properties were investigated using Marshall method. A repeated indirect tensile load test also conducted determine resilient modulus. Marshall’s stability, air voids, unit weight, flow, voids mineral aggregates examined. results compared analyzed with base sample. It observed that adding decreased consumption reduced optimum content (OAC). Additionally, mixture improved its service life extended after plastic. value modulus (RM) increased when percentage added well. Reuse mixtures achieves concept an environmentally friendly solution transportation area because it reduces costs Moreover, optimal paper achieved at 11%.
