PETROMAT Enviro is a paving fabric that features the strength properties of AASHTO M288, contains no fiberglass, installs directly onto a milled surface, and easily mills and recycles.
Installs directly on a milled surface
PETROMAT Enviro is engineered to install directly over a milled surface without a leveling course, saving and average of $4 per square yard. An elongation of twenty percent is needed to conform to a milled surface. Enviro has a minimum elongation of 25 percent, allowing it to easily conform to the entire surface of a milled pavement without breaking. In contrast, glass-based products have an elongation of around three percent, so leveling course must always be used.
Optimal stress absorption and moisture protection
Research shows that stress absorption and moisture protection are the most important qualities of a paving fabric. The thickness of an overlay will determine how well cracks and joints in the pavement are mitigated. The thicker the interlayer, the more crack inducing stresses are attenuated. When saturated with asphalt tack coat, Petromat ENVIRO is two to three times thicker than other paving interlayers, enabling resistance to reflective cracking comparable to an additional one and a half inches of overlay thickness.
PETROMAT Enviro is designed to easily mill and recycle, creating sustainable and environmentally friendly roadways. Enviro offers all of the benefits of a traditional paving fabric in an interlayer that easily mills and recycles.
