When reflective cracks migrate to the surface, the long-term integrity of flexible and composite pavements can be quickly compromised. Conventional practice in dealing with this type of distress is to mill the top few inches and overlay the remaining pavement with “fresh” asphalt. When a geogrid interlayer product is included within the overlay, the time for reflective cracks to appear again is typically extended two to three fold. Very similar to rebar for a concrete road way fiberglass geogrids enhance the tensile element of asphalt. Inclusion of geogrid interlayers can therefore significantly reduce the long-term maintenance costs for pavement owners. A variety of fiberglass road grid are available to help mitigate different crack types and degrees of severity.
