Types of Treatment

The type of preservation treatment applied is dependent on many factors including roadway condition, location, and age. The Pavement Condition Index, or PCI, assigns a rating to each roadway based on those factors. PCIs range from 0 to 100, with higher PCI values indicative of better pavement conditions.

Typically applied treatments 
  • Crack Seals - Filling cracks in the roadway with hot sealant to protect the pavement from water, which can enter the cracks and further damage the road.
  • Slurry Seals - Protecting existing pavement with a mixture of fine crushed rock and liquid asphalt cement applied over the entire roadway surface.
  • Overlays - Repaving the top layer of the roadway.
  • Asphalt or Concrete Replacement - Completing small asphalt or concrete patch repairs.
