A True Comparison of Paving Mats
Brought to you by:
It can be very confusing when deciding among different fiberglass paving mats in the marketplace. Although they may appear to have similar physical properties when comparing technical data sheets, it's important to have an understanding of the composition of these products that make their performance very different.
To demonstrate and quantify various products' ability to resist cracks, the Texas Transportation Institute (TTI) conducted an overlay fracture performance study. The TTI testing captured the stress and strain improvement provided by interlayers and allowed for the calculation of an interlayer product's ability to resist reflective cracking. The CMF (Crack Mitigating Factor) quantifies the combined improvement of the reinforced asphalt vs. unreinforced asphalt in terms of dealing with both stresses and strains.
