Performance Evaluation of Asphalt Mixtures under dry and wet mixing containing Sustainable Silicon Waste Material

Abstract

Across the worldwide modern infrastructure of transportation is very prominent for social beings in everyday life. With the passage of time gradually surge in growth rate as well as the number of trips. To enhance the performance pavement different agencies are research on the behavior and condition of the pavements. Development of sustainable infrastructure across the globe especially recycling and production by using waste material for road network. The two major predominant factors which relate with construction for developing of sustainable transportation network. Globally, a huge amount is produced of basic HMA and being utilized to produce a handsome volume of the finalization of road materials. This study relates with method of modification by addition of silicone covers of mobile as a waste material. In this study also present an innovational technique of mixing - by dry mix and wet mix and comparison between the performance of both mixing techniques. In our study, utilizing two different sources of aggregate Margalla crush and Sargodha crush 60/70 grade bitumen and silicone covers and used as a modifier. By using high shear mixer having 1100rpm rotating speed prepared Modified Bitumen (MB). Silicone waste are partially replacement at 5,10,15,20 and 25 respectively with bitumen, in this investigation. Basic test of bitumen (Penetration Softening point ductility flash and five points.) with addition of varying percentages shows variable results up to 20% replacement of silicone. Furthermore, for evaluation of pavement performance, Indirect tensile strength (ITS), Moisture Susceptibility Analyses and Rutting Depth resistance test perform on virgin HMA and Modified HMA with 20 % partial replacement of silicone. The result based on performance testing are promising and utilization of silicone waste material consequent impact on the life cycle cost of road infrastructure for sustainable development by reducing the quantity of bitumen which is cost effective. In mixing techniques, dry mixing yield better perform in rutting in term of stability, flow as well as moisture susceptibility. The test results showed that the evaluated quarry aggregates were suitable for use in road x paving. Each aggregate sample has different properties, which are very important from a design, economic and environmental point of view. Margalla aggregate was observed to provide superior mechanical properties compared to Sargodha crush. It is found that modified HMA having 20% silicone. To be economical for huge volume sustainable road construction as well as maintenance. Except having more other significant advantages like reduction in waste and increase sustainability.
