Lignin-modified bitumen: Exploring characteristics and performance
Abstract: The surge in crude oil prices has sparked interest in finding efficient and cost-effective alternatives to bitumen, a binder used in road pavement. Bitumen, derived from crude oil distillation or natural deposits, is primarily utilized in pavement grade bitumen, accounting for 83% of its usage. However, traditional hot mix asphalt, which relies heavily on bitumen, emits significant amounts of CO2, CH4, and N2O, contributing to environmental concerns. To address these …

Enhancing Bituminous Mixes with Recycled Polyethylene: Performance Analysis Using Marshall Stability Test
Abstract: This study investigates the impact of incorporating recycled low-density polyethylene (LDPE) and high-density polyethylene (HDPE) in bituminous mixes for potential use in flexible pavement construction. Utilizing a Marshall Stability Test, various proportions of LDPE and HDPE were analyzed to determine optimal stability and flow characteristics. The test maintained a fixed Zycotherm content at 1.5% and varied LDPE content from 2% to 5% by weight, while HDPE content was also tested …
