Crack Sealing Machine uses visual inspection to evaluate pavement surface conditions. The key to a useful evaluation is identifying different types of pavement distress and linking them to a cause by using Crack Sealing Machine. Understanding the cause for current conditions is extremely important in selecting an appropriate maintenance or rehabilitation technique.
There are four major categories of common asphalt pavement surface distress, the most distress can be repaired by Crack Sealing Machine:
Surface Defects: Raveling, Flushing, Polishing
Surface Deformation: Rutting, Distortion—Rippling and Shoving, Settling, Frost heave.
Cracks: Transverse, Reflection, Slippage, Longitudinal, Block and Alligator Cracks.
Patches and Potholes. Deterioration has two general causes: environmental due to weathering and aging, and structural caused by repeated traffic loadings.
Obviously, most pavement deterioration results from both environmental and structural causes. However, it is important to try to distinguish between the two in order to select the most effective rehabilitation techniques.
