When RAP is processed for reuse, it is first placed into a crusher and then sent through a screening process to remove large pieces. In some cases, traditional paving fabrics have been difficult to process due to large fabric pieces clogging the scalping screen. It is not uncommon for large pieces of paving fabric to slow down, or even shut down, the screening process. The loss of efficiency is one reason some recyclers have started charging a premium for processing RAP with traditional paving fabric, and other recyclers have refused to process it all together. Petromat Enviro was developed to solve the milling and recycling issues associated with traditional paving fabric. This new, patent-pending paving fabric is engineered to easily mill into small pieces so it can be recycled into RAP without compromising its ability to provide moisture protection or stress absorption to slow fatigue and reflective cracking. Glass-based geosynthetic interlayers were also introduced in response to challenges of milling traditional paving fabrics. Because of their brittle nature, fiberglass strands do mill and recycle easily.

Petromat is used to extend the life of all paved areas, including highways, parking areas and airport pavements. It is a nonwoven fabric that is field saturated with an asphalt cement tack coat to create a continuous moisture barrier and stress absorbing interlayer in new or rehabilitated pavements. Petromat extends the life of new asphalt pavements and overlays by acting as a barrier to prevent water infiltration from the road surface into the base course. It also performs as a stress-absorber to reduce reflective and fatigue cracking.
Today it continues to be the most proven asphalt paving fabric in the market. No other product provides a better pavement moisture barrier or stress absorbing interlayer to prevent reflective cracking. Product Information.
Our experience with asphalt overlays is extensive. An asphalt overlay is a process in which an existing worn asphalt surface is paved over with a new layer of hotmix asphalt material and applied by an asphalt paving machine. Between the old and new layer of asphalt, a glue like binder called tack or SS-1h is applied and fuses the two layers together. Both of these options were very costly and we're now finding that it's rarely necessary. This approach of repair is following the same trends as the thin overlays being performed on streets and roads across America. Asphalt overlays are both the smartest and most economical approach to repairing your asphalt today. The reason for this is because asphalt overlays will give your parking lot that "brand new look" while utilizing most of your existing asphalt surface below. A petromat overlay is very similar to an asphalt overlay. The main difference is that between the old asphalt and the new asphalt, we include the installation of a nonwoven petroleum fabric that looks like a black cloth. This cloth is installed via a machine that pulls the material tightly and glues it to the tack emulsion on the existing surface.
