Mats for use in paved surfaces

A paving mat (14) for use in a paved surface (10) includes a fibrous mat in the form of a paving mat. The fibrous mat includes a fibrous matrix containing a mixture of polymer fibers, first mineral fibers having a first median length, and second mineral fibers having a second median length that is d...

Zusammenfassung:A paving mat (14) for use in a paved surface (10) includes a fibrous mat in the form of a paving mat. The fibrous mat includes a fibrous matrix containing a mixture of polymer fibers, first mineral fibers having a first median length, and second mineral fibers having a second median length that is different from the first median length. In another embodiment, the paving mat includes a fibrous mat including a fibrous matrix which is bonded together by a binder. In one embodiment, the binder is a mixture of different binders. The fibrous matrix includes a mixture of mineral fibers in an amount within a range of from 61 wt% to 85 wt% and polymer fibers in an amount within a range of from 15 wt% to 39 wt%. The polymer fibers have a melting point greater than 320 DEG F (160 DEG C). The mat has a stiffness in the machine direction within a range of from 65 g-cm to HO g- cm. The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load
