PolyChip is a unique combination of recycled tire rubber, polymer modified asphalt and coated aggregate which provides a waterproof membrane over the pavement surface.
The process begins with a thorough cleaning of the roadway surface utilizing high- speed air blowers and/or mechanical sweepers. Pavement cracks ¼ inch wide or larger are then filled with a hot-applied rubberized crack sealer. PolyChip oil containing recycled tire rubber and polymers is heated and applied to the surface from a distributor truck. Immediately following the oil application, aggregate is evenly placed using a chip spreader. A rubber tire pneumatic roller is used to help compact the aggregate in place. After curing, loose stones are swept from the pavement surface. The final step is the application of an asphalt emulsion known as “fog seal.” Fog sealing provides an attractive appearance while improving surface cohesion.
The PolyChip system remains flexible at cold temperatures and maintains integrity at high temperatures to help reduce reflective cracking. The finished surface requires very little maintenance and is extremely durable.
Over the last ten years, Sunland has completed nearly 60 PolyChip projects totaling $8.5 million. With offices in Arizona, Colorado, Nevada, and New Mexico, Sunland performs polychip services throughout the southwest.
