microsurfacing & High Performace slurry Seal
Microsurfacing is the most economical choice for preserving pavement. This mixture of polymer modified asphalt emulsion, fine graded crushed aggregate, and mineral filler, creates a hard asphalt wearing surface.
When applied over asphalts beginning to show signs of distress, microsurfacing seals the surface from moisture intrusion, preventing future oxidation of the pavement.
This wearing course adds increased skid resistance, improves overall ride quality, and restores a uniform black appearance to the roadway.
Chip & CApe Seal
Chipseal is a pavement surface treatment that combines one or more layers of asphalt emulsion or modified performance grade asphalts with one or more layers of fine aggregate. This technique seals the pavement with an impermeable and skid resistant layer wearing course. Chip Seals are typically used on rural roads carrying lower traffic volumes.
Cape Seal is a process where a Microsurfacing or Slurry seal application is placed over the Chip Seal.
Life Extension:
Chip Seal 3-6 years dependent on application
Cape Seal 6-10

Ultra Thin Overlay
Ultra Thin Overlay is a high-performance surface course over either asphalt or concrete pavements. The one-pass construction process consists of a heavy application of polymer modified asphalt emulsion membrane followed by an ultrathin HMA, both placed by a single machine. The thick polymer membrane seals and protects the surface and provides superior bonding of the ultrathin mix to the pavement.
Life extension 8-10 years
Crack Seal
Cracking in pavement occurs when a stress is built up in a surface layer that exceeds the tensile of shear strength of the pavement causing a fissure or crack to open. Crack sealing and crack filling are methods which can be used to repair these cracks in pavement surfaces.
Crack Seal is a polymer modified rubber blend that produces a strong yet flexible repair to pavement cracks and construction joints. Ultimately, when applied at the right time, this seal will help keep out water from the subbase yielding longer pavement service life.
Life Extension
Crack Seal 1-3 years
Micro Joint 5-8 years
(Micro Joint Repair can be used to repair longitudinal cracking)
Fog SeaL
Fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged (oxidized) pavement surface. Fog seals are low cost and are used to restore flexibility to an existing HMA Pavement surface. They may be able to temporarily postpone the need for a surface treatment or non-structural overlay.
