路桥工程中沥青路面开裂是普遍存在的现象,不管其基层是柔性的还是半刚性的。路面裂缝的危害在于从裂缝中不断进入水分,使基层甚至路基软化,导致路面承载力下降,产生唧浆、台阶、网裂等病害,加速路面的破坏。因此,探讨路桥工程中沥青路面裂缝产生的原因及预防措施。 Asphalt pavement cracking in road and bridge engineering is a common phenomenon, regardless of whether the grassroots are flexible or semi-rigid. The harm of pavement cracks lies in the constant infiltration of water from the cracks and the softening of the grassroots and even subgrade, resulting in the decrease of bearing capacity of the pavement, resulting in diseases such as grouting, steps and net cracking, and accelerating the destruction of the pavement. Therefore, the reasons for the cracks in asphalt pavement in road and bridge construction and the preventive measures are discussed.
