Owens Corning also makes TruPave® engineered paving mat for the pavement interlayer market
TruPave® mat delays reflective cracking, forms a nearly impermeable moisture barrier when applied with asphalt and does not shrink or melt like competitive products. TruPave® engineered paving mat extends the life of a hot-mix asphalt pavement overlay and lowers the cost of ownership.
TruPave® mat is also millable and recyclable at the end of the pavement life – a significant consideration since asphalt pavement is the highest volume recycled product in the U.S.
Originally introduced in 2001 after about two years in the development stage, TruPave® mat is a wet-formed mat comprised of fiberglass and polyester fibers that is applied with hot asphalt. The product provides a continuous, non-deforming water-resistant barrier under a new top surface of asphalt paving.
High temperature stability is a cornerstone feature of the TruPave® engineered paving mat. TruPave® engineered paving mat remains dimensionally stable up to 495°F and hence is ideal for rubberized hot-mix asphalt (HMA). HMA may reach temperatures in excess of 350°F, which is well above the melting point of many interlayer materials. Exceeding the melting point of an interlayer material can result in dimensional instability and diminished performance.
Pavement overlays that do not include TruPave® engineered mat will typically show reflective cracks within several months to a year. With low elongation and good tensile strength, TruPave® mat delays reflective cracking, extends the life of pavement and dramatically lowers repair and maintenance costs.
