Waste Tire as an Asphalt Cement Modifier for Road Pavement

Abstract

In view of the issue related to the rising cost of construction and need to contribute to the solution of the ever-growing environment backlog problems, the study paved the way for the recognition of using waste tire as an asphalt cement modifier for road construction to solve the current issue on waste disposal. In it’s entirely, this experimental study aimed to use Marshall and immersion-compression tests to determine the effect of waste tire as an asphalt cement modifier in Marshall Stability and flow, density and voids contents, and effect of water and compressive strength of compacted bituminous materials of highways. Observations from the tests performed were conducted in the laboratory where precise data were gathered and completely attained. Some interesting insights of the study are: (a) scrap waste tire is a partial replacement by 2% total weight of aggregate retained in No. 4 sieve has an average performance; (b) the use of scrap waste tire would result in the reduction of waste; (c) test result of specimens indicate the stability, and bonding strength of properties, and different reaction when gradation and scrap tire contents have varied and (d) marshall test having an appropriate workable mixing and right temperature gave sufficient compressive strength and lessen its flow or it deformation under a certain loads.
