连续配筋混凝土路面裂缝发展规律浅析

摘要

裂缝是混凝土路面的薄弱点，而裂缝宽度和间距是评价的直观指标。以耒宜高速公路为依托，对新、旧连续配筋混凝土路面进行裂缝调查，对裂缝形态、裂缝宽度、裂缝间距3个方面进行了分析、评价，并提出裂缝间距、宽度与龄期的关系，以供读者参考。%Crack is weak spot of concrete pavement,and crack width and spacing is intuitive eval-uation index.This paper,taking the appropriate Leiyang-Yizhang highway as the main body,to new and old CRCP crack investigation,and with crack morphology,crack width,crack spacing three aspects has carried on the analysis,evaluation,and put forward the crack spacing and width of its relationship with age,for readers reference.
