For AC pavement cold joints, concrete to asphalt interfaces, and perimeters of patch repairs. |
The National Center for Asphalt
Technology (NCAT) study on longitudinal joints has determined that
Crafco Pavement Joint Adhesive is the winner for reducing
longitudinal joint cracks and joint failure over all other joint
sealant products and techniques tested. The studies took place over
a six-year period (Sept. 1995 - July 2001) and were performed in
five states: Pennsylvania, Colorado, Michigan, Wisconsin and New
Jersey. These tests confirmed that longitudinal joints in asphalt
pavement, if not treated, would encounter cracking, raveling and
eventually fail due to water infiltration, thermal movement and low
density. They have found that Crafco's hot-applied modified asphalt
composition effectively bonds paving passes together creating a
watertight seal during thermal movement resulting in improved
long-term performance of the joint with no significant cracking.
This product is also effective for waterproofing exposed edges of
asphalt concrete pavement areas such as at the curb gutter, and
shoulder interfaces. Additionally, waterproofing can be assured
where manhole covers and hand valves (gas, water, etc.) are
installed in asphalt concrete pavement. Like other Crafco products
this product is easy to apply using Crafco's Melter/Applicator
equipment. |
