ABSTRACT:
A method of paving and resurfacing, with paving materials consisting of a matrix of particulate materials and a binder, utilizes a mat including a fabric layer with a plurality of rigid, upstanding tubular members spaced in a uniform array of staggered rows. When asphalt paving materials are employed, a conventional base layer is first coated by an asphaltic binder material. The mat is then spread over the binder material. A top layer of asphaltic paving material is applied over the mat, to a level above the tubular members. The top layer is then compacted within and around the tubular members. The mat may be applied selectively in only high volume traffic lane portions to minimize paving costs. The mat inhibits subsequent migration of the asphalt due to high temperatures and heavy loading. Other paving materials, of the type consisting of a matrix of particulate materials selected from the group of sand, gravel, crushed rock and crushed shell, and a granular binder selected from the group of lime, cement, and soil cement, may also be employed in conjunction with the mat. When such non-asphaltic paving mixtures are employed, the mat may be secured to the base layer by mechanical fasteners.
