Pavement Design with Hot-Mix Reclaimed Asphalt Pavement (RAP) Bituminous Concrete as the Surface Course

Abstract

The scrap pneumas are pneumatics that can no longer be utilized to build them. The destruction or accumulation of discarded pneumatic garbage in landfills has several environmental problems and adverse effects on human health. One of the uses of discarded tires is Bitumen Pavement Amendment. The aim of this study is the examination of the different characteristics of bitumen produced by adding scrap value and checking the working ability of the mixture. Scrap pneumatic materials increase the physical characteristics of bitumen, including penetration and softening point, and a changed binder has a lower penetration and a better softening point in comparison with plain bitumen. The application of scrap The use of scrap tires has been demonstrated to enhance the physical characteristics of bitumen including penetrating points and smoothing, and a changed binder has less penetration and a greater softening point when compared with nice bitumen. Using waste pneumas enhances bitumen's physical characteristics. Hot-mix reclaimed asphalt pavement (RAP) bituminous concrete has a bulk specific gravity (Gsb) 2.604, apparent specific gravity (Gsa) 2.689, and effective specific gravity (Gse) 2.647 The static stability of hot-mix reclaimed asphalt pavement (RAP) bituminous concrete is 92.95%. The physical characteristics of bitumen, such as penetration and softening point, are improved when scrap is used. A modified binder has a lower penetration value than pure bitumen. Drink more softly in a modified binder. It happens in than ordinary bitumen.
