(Hot applied Polymeric sealing compound)

Material used to exceed federal specification SS-S-164

1.-W.R. Meadows Sealtight #164: Hot applied polymeric sealer that provides a positive seal during expansion and contraction of cracks in asphalt.

2.-Black Beauty: Slag product that is placed over the sealed cracks allowing immediate traffic flow. This method is only used when traffic flow may not be interrupted.

Application of Hot Crack Sealer

Prior to the application of crack sealer, cracks and joints over 3/8" shall be cleaned with an 8 hp wire wheel crack router. The crack router is used to remove all vegetation and debris from the cracks. The entire crack depth shall then be cleaned using air blowing techniques or compressed air to provide a crack free from all debris, dust, loose material, and moisture. The cleaned cracks shall then be sealed using a double oil jacketed melter applicator.

This machine heats the sealing compound to 370 degrees. (Any direct flame melter will burn the sealing compound and is not allowed to be used.) Application of the sealant is applied from the bottom up to the surface level. The cracks are slightly overfilled and immediately squeegeed to provide a neat uniform band approximately 2" wide. This sealant takes approximately 10 minutes to cure. After curing, the sealant provides a track free finish.
