How to Repair Asphalt Cracks in the Road - Espina Paving Inc

Naturally, during a high quality asphalt construction job, the joints between the sections will be properly sealed together; if they are not, cracks can form along these joints. Even if the job was done properly, wide ranging temperature fluctuations, poor drainage and asphalt shrinkage can still cause cracks at these vulnerable joints.

What are the causes of longitudinal cracks and transverse ...

Longitudinal cracks in bituminous pavement are usually caused by fatigue failure under repeated traffic loading. In thin pavements, cracking starts at the bottom of the bituminous layer where the tensile stress is the highest and then it spreads to the surface as one or more longitudinal cracks.
