SBS (Styrene-Butadiene-Styrene Block Copolymer) Modified Asphalt can significantly improve the pavement performance of asphalt, mainly in the following aspects: enhanced high-temperature stability, low-temperature crack resistance, fatigue resistance, bonding strength, and waterproofing performance,
Polymer modification of bitumen has been commonly performed since the 1980s to decrease bitumen (and pavement) susceptibility to high and low temperatures, reducing common failure mechanisms such as rutting and cracking in bitumen concrete and bituminous roads.[1]The addition of thermoplastic or elas
The use of (recycled) plastics and (waste) vulcanized rubber powder is the main polymer of raw materials, and composite organic additives are selected to fully combine with asphalt components. The physical and chemical reactions between different components are completed in dynamic mixing, establish
Styrene-butadiene-styrene’s block copolymers (SBS) is made up of three segments. The first and third segments on two sides are long chains of polystyrene (tough hard plastic), while the middle is a long chain of polybutadiene (rubber-like). SBS has a high range of operating temperature all the while
