The use of cement production waste to improve the properties of hot mix asphalt concrete
(JORDAN UNIV SCIENCE & TECHNOLOGY, 2019) Abed, Adil; Eyada, Saadoon
Cement bypass dust (CBPD) or cement kiln dust (Ki) is a by-product (waste) generated during the production of Portland cement. Thousands of tons per day are disposed to the land fill. This big amount of waste has an adverse effect on the environment and needs a lot of money and effort for recycling or disposal. In this study, in addition to Ki, lime stone dust is used as a control filler. Laboratory tests have been conducted in order to evaluate the properties of each type of filler. The tests cover: grain size distribution, specific gravity (Gs), specific surface area (SA), pore volume (PV), mineral composition, pH and chemical composition. To study the effect of Ki on the performance of HMA mixture, several tests are conducted, including Marshall stiffness, indirect tensile strength, moisture susceptibility and creep tests. A mechanistic empirical pavement design approach in conjunction with viscosity test have been used for further analysis. The test results showed that cement kiln dust enhanced Marshall stability, mix cohesion, fatigue life, mix moisture resistance and rutting life of asphaltic mixture. It is recommended to be used in order to enhance the properties of HMA concrete and reduce the pollution and cost of pavement production.
