Procedures

Installing SafeLane Surface Overlay is a simple process that follows AASHTO (American Association of State Highway and Transportation Officials) Task force 34 protocols. Here are the steps:

  • Surface preparation to clean off oil and contaminants, including surface repair if needed.
  • Concrete surfaces are shot-blasted to an ICRI (International Concrete Repair Institute) level of 5-7 to roughen up the surface and ensure a good chemical bond.
  • Crews mix and prepare the epoxy. Crews manually spread the epoxy using squeegees. The aggregate is then immediately broadcast across the surface using a shovel.
  • Overlay is applied in two applications for road and bridge projects. One application for commercial and airport uses.
  • The epoxy is left to cure for seven to eight hours depending on outdoor temperatures.
  • After it cures, loose rock is scraped off and vacuumed up by a sweeper truck, followed by leaf blowers.
  • Surface is reopened to traffic.
