Topps Asphalt  St Louis provides hot pour crackfiller for parking lots, roads and concrete streets.

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)

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

The hot pour crackfiller is a rubberized block, 27 - 35 lbs which is placed in a melter and heated to 350 degrees. It is typically used to fill cracks 1/4" to 3/4" wide and leveled out with a V-Shape squeegee.

The crackfiller is used in parking lots, roads and concrete streets. We do hot used the rubberized hot pour in driveways. The reason we do not hot pour driveways is because the melter needs to be idle ( can not drive with the melter on ) and needs approximately one hour to heat up the material for use.
