It is caused by insufficient pavement thickness; lack of compaction of the asphalt, stone base or soil; weak asphalt mixes; or moisture infiltration. FIX: If rutting is minor or if it has stabilized, the depressions can be filled and overlaid. If the deformations are severe, the rutted area should be removed and replaced with suitable material.

 · They can be caused by settlement of the underlying material, soil drying, or lack of lateral support. Possible contributors can be nearby trees or shrubs. These should be cleared away. Filling with asphalt emulsion slurry will often take care of this problem. Drainage may need improvement. 2. Slippage cracking.

Root cracks are caused by tree roots growing underneath a paved asphalt surface. They appear as winding, raised linear bumps and can eventually open up to become larger cracks. 13. Linear Cracks. Linear cracks are long cracks that develop primarily when water is able to penetrate the surface of the asphalt pavement.
