pavegrid is a pavement reinforcement product composed of a net of
infinite glass or polyester filaments stitched onto a non-woven
fabric (pavemat). Pavegrid combines the reinforcing capability of
glass or polyester filaments with the effective moisture proofing
function of paving fabrics, making it an ideal product to prevent
cracking and reflective cracking in pavements. Pavegrid pavement
reinforcing fabric was developed to prevent the development and
propagation of reflective cracking in asphalt pavements and through
this effect to significantly diminish frost damage, reinforce
pavements, improve pavement durability and help evenly distribute
loads. When using the products to compensate for substructure
defects and settlements, it is advisable to use them in combination
with other structural reinforcing methods. Pavegrid glass filament
fabrics can be used over the whole pavement area not only to
rehabilitate old roads built on weak sub grades but also on road
bases having cracked pavement. This will result in a durable and
permanent road at reasonable cost. The demolishing of the whole road
structure, the replacement or reinforcement of the existing road
base and the construction of the new road structure often present
very high costs to the road operator. In such cases the solution is
the use of the glass fibre reinforced fabric, because after the
pavement defects are repaired, permanent and significant quality
increase can be achieved by laying one layer of fabric on the
surface and installing one asphalt overlay. Due to the more even
load distribution the rate of road base deterioration will also
reduce.
A special field of application is the prevention of reflective
cracking in asphalt pavements constructed on existing concrete
pavements such as airport aprons, runways and taxiways. Pavegrid can
also be ued to prevent reflective cracking when making asphalt
overlays on cracked lean concrete pavements.
A
further special application is the construction of joints between
embankments and engineering structures and, in case of road
widening, over the boundary between the existing and the new road
sections.
