PG道路嵌缝料是在851聚氨酯防水胶的基础上,参照HDS填缝料实样的性能指标比较筛选、研制而成,是一种网状结构的聚氨脂类聚合物。试验和工程现场观测表明,这种嵌缝料可以冷作施工,与热沥青混合料相比,其粘结强度、弹性、失粘时间、低温脆性等均有所改善,且可减少环境污染。
PG road caulking material is based on the 851 polyurethane waterproofing glue, with reference to HDS sealant sample-like performance comparison screening, developed from, is a network structure of polyurethane polymer. Tests and engineering field observations show that this kind of caulk can be cold-worked. Compared with hot asphalt mixture, its bonding strength, elasticity, tack-free time and low temperature brittleness are all improved, and the environment pollution can be reduced.
