most common types of cracking

Cracksealing is the best investment that a business owner or property manager can make for the protection of their pavement. An economic hot-pour rubber material for large scale sealing, cracksealing will provide excellent cohesion and adhesive qualities that remains ductile and flexible at the low temperatures of winter. Additionally, crackseal will not flow or migrate during the high-temperatures of summer.

The Most Cost-Effective Solution

Longitudinal Cracking

  • Longitudinal cracks are parallel to the pavement's centerline or laydown direction. They may be caused by:
    1. Poorly constructed pave line joints
    2. Shrinkage of the asphalt cement surface due to low temperatures or hardening of the asphalt and/or daily temperature changes
    3. Reflective cracking caused by cracking beneath the asphalt surface course



Transverse Cracking

  • Transverse cracks extend across the pavement at approximately 90 degree angles to the pavement's centerline.
    1. They may be caused by shrinkage of the asphalt cement surface due to low and sudden changes to temperature
    2. Reflective cracking caused due to the hardening of the asphalt
    3. Transverse cracks are usually not related to load distress


Block Cracking

  • Block cracks are interconnected cracks that divide the pavement into rectangular pieces. 
    1. The blocks may range in size from approximately 1’ by 1’  to 10’ by 10’.
    2. Block cracking is caused mainly by the shrinkage of the asphalt cement and daily temperature changes.
    3. Block cracking is not load related distress.

WHY PROTECT  YOUR PAVEMENT WITH CRACKSEALING?


  1. Protects the sub-base and/or stone base from moisture infiltration in cracks 1/4 inch to 1/2 inch.
    • Usually develops into further damage like alligator cracking or potholes.
  2. Shields the pavement surface against an average of 36 freeze-thaw cycles per winter season.
  3. Helps eliminates the damaging effects of vegetation, dirt, and debris by removing all foreign matter with compressed air to both clean and dry the crack.
  4. Extends pavement life when applied every 2-3 years.
  5. Cracksealing is a cost-effective solution and critical to one's  Pavement Maintenance Plan (PMP).
