水泥混凝土路面在使用年限内开裂的原因及处理措施

Reasons and Treatment Measures for Cracking of Cement Concrete Pavement Within Its Service Life

水泥混凝土路面具有刚度大、承载能力强;耐久性优良、耐高温性强;抗弯拉强度高、扩散荷载能力强、疲劳寿命长;耐腐蚀性强;稳定性好、使用寿命长;日常养护费用低等诸多优点,被广泛应用于市政道路建设,在长期的运营过程中,各种病害随之涌现,最严重的就是裂缝破坏。在老路改建工程中,对针对该道路水泥路面贯穿性裂缝产生的原因及工程处理措施进行剖析,对该道路的路面裂缝处理后方可对老路进行改扩建。

Cement concrete pavement has high stiffness and strong bearing capacity;excellent durability and high temperature resistance;high flexural tensile strength,strong diffusion load capacity,long fatigue life;strong corrosion resistance;good stability and long service life;It has many advantages such as low daily maintenance costs,and is widely used in municipal road construction.During the long-term operation process,various diseases will emerge,and the most serious one is crack damage.In the reconstruction project of the old road,the reasons for the penetrating cracks in the cement pavement of the road and the engineering treatment measures are analyzed.
