| 摘 要： | 水泥混凝土路面常见病害之一是路面出现裂纹或较大裂缝,严重影响了路面质量。如何提高混凝土的抗裂性、降低其脆性在路面混凝土中尤为重要。本文试验研究了骨料岩性对混凝土力学性能、极限拉伸、干燥收缩、自身体积变形、热膨胀系数等性能的影响,以期获得骨料对混凝土抗裂性能的正确认识。

| Abstract: | One of common diseases in cement concrete pavements is cracks or larger cracks on pavement so as to seriously influence on the pavement quality. How to enhance the crack resistance of concrete, to reduce its brittleness in the pavement concrete is important. The paper tests and studies on the influence of aggregate rock feature on concrete performance such as mechanics performance, ultimate stretching deformation, dry contraction, self volume deformation, thermal expansion coefficient etc. so as to obtain the correct understanding of aggregate to concrete crack resistance. |

| Keywords: | cement concrete pavement aggregate concrete crack resistance |
