Paving Fabric Installation
Cracked pavements allow surface water to permeate subgrade soils, which saturate and weaken the subgrade. Normal maintenance procedure is to repave with an asphalt overlay. This resurfacing procedure can extend the useful life of a pavement section at a lower cost than a full replacement. However, the extended useful service life of an overlay can be reduced by subgrade saturation/weakening which causes fatigue cracking and propagation of cracks from the original pavement through the existing overlay (reflective cracking). The addition of paving fabric into a pavement overlay reduces the effect of mechanisms which deteriorate pavements and increases the life of the overlay pavement section. When installed with a proper surface preparation and tack coat, paving fabric forms an impermeable membrane that prevents the penetration of surface water through the pavement and also provides a stress relieving layer which inhibits reflective crack growth.
The two most common paving fabrics used in today’s market are Mirafi®’s MPV-(series) and Owens Corning Trumbull’s Trupave®. Diversified Asphalt Products, Inc. uses specially modified John Deere tractors enabling us to install paving fabrics in a wide range of projects, from the tiniest parking lot to a major street renovation.
