Surface cracks are a natural function of the aging of asphalt. These types of cracks cannot be fully eliminated; however, the detrimental effects can be minimized with Hawk-Seal-E.  The low viscosity and multiple applications of Hawk-Seal-E allow it to flow into, penetrate and seal-off even small cracks. Existing cracks are sealed and future crack formation is inhibited because the asphalt binder is restored.

  Asphalt and concrete surfaces are subject to reflective cracking.  These are cracks appearing on the current surface which are actually reflecting the crack pattern in the pavement underneath.  After an overlay, these cracks will reflect back up to the surface at a rate of from ½ inch to 2 inches per year.  Reflection rate depends on quality of asphalt and installation, moisture, traffic loads and temperature changes.

Thermal or Block Cracking:
 is usually rectangular in shape. Block cracking is not load associated. These cracks are caused by the natural shrinkage of the asphalt and the stress/strain cycle of the daily temperature changes. 

Alligator - Fatigue - Pattern Cracking:
This is a series of interconnecting cracks caused by fatigue failure of the actual asphalt material, the base or the sub-grade. If left untreated, the area will need to be excavated and replaced.

Raveling:
The separation of the aggregate particles from the surface of an asphalt pavement. Hawk-Seal-E strengthens the binder and significantly reduces this process. The primary cause of raveling is water entering the pavement through cracks and voids. Long-term emissions from vehicles. The hydrocarbons act as solvents to asphalt and degrade the
surface. Horizontal shear stresses resulting from the action of traffic.
