沥青路面裂缝新型贴缝带的研制与应用

Development and Application of New Type Taped Seam for Bituminous Pavement Crack

沥青路面因车辆荷载、温度变化和路基结构等多方因素影响会产生各种各样的裂缝,由于路表水的浸入,裂缝两侧的路面结构层和土路基的含水量增大,致使路基和路面强度降低,在车辆荷载的作用下,加快路面的裂缝产生,大大缩短沥青路面的使用寿命。通过优化材料配方,研制出高性能、使用便捷的贴缝带产品,处理沥青路面早期裂缝,能有效延长沥青路面的使用寿命。

Bituminous pavement will produce all kinds of cracks due to the factors of vehicle load, temperature variation and subgrade structure. Owing to the immersion of surface water, moisture content of the pavement structure layer and subgrade between the two sides are magnified, which cause the strength reduction of subgrade and pavement strength. Under the function of vehicle load, the production of pavement cracks is speeded up and the service life of bituminous pavement is largely shortened. Through optimizing the material prescription, develop high - performance and convenient taped seam products, to deal with the early stage cracks of bituminous pavement, the service life of bituminous pavement is effectively extended.
