SBS (Styrene-Butadiene-Styrene) is an effective toughening agent for recycled PS, addressing its inherent brittleness while maintaining processability. To balance performance and cost, here are key principles for selection:Molecular Weight Control: Optimal range is 80,000–200,000.Below 80,000: SBS t
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
