The effects of sun, moisture, and traffic primarily cause asphalt cracking. The sun oxidizes asphalt cement, causing shrinkage, and creating separations and cracks.  Moisture reaches through these separations to the pavement's subsurface causing potholes.  Heavy vehicular traffic further accelerates the pavement deterioration.

Crack sealing is the placement of specialized treatment materials above and/or into working cracks to prevent the intrusion of water or incompressible material, such as sand, stone, and dirt.  Crack filling is the placement of  ordinary treatment materials into non-working cracks to substantially reduce infiltration of water and to reinforce the adjacent pavement.

Hot pour sealants are a blend of asphalt cements, extender oils, thermoplastic rubbers, antioxidants, and fillers.  One of the most  important characteristics of hot pour sealants is its ability to be relatively unaffected by what caused the pavement to fail.  P & T Products manufactures a variety of sealants to meet each pavement maintenance need.  P & T uses high quality raw materials in order to produce high quality sealants. 

Crack sealing is the most economical method to lengthen the life of a pavement.  Proper attention to cracks will prevent further problems such as potholes.  Dura-Fill prolongs pavement surface life by sealing cracks and surface joints from water penetration. 

YES!  Crack sealing is the most effective and least costly preventative maintenance program available.  Proper crack repair procedures can extend the life of asphalt and portland cement.

The sooner, the better. Any crack in the pavement will allow moisture to penetrate to the subsurface and shorten the life of the pavement.  Substrate and air temperatures must be above 40^o F and the surface should be properly prepared before sealing. 

Proper surface preparation will facilitate a strong adhesion to the surface.  P&T Products recommends routing all cracks prior to cleaning and sealing the surface.  The maximum extension and compression should not exceed 50% of the width.  Best results are obtained when joints are opened at least ½ inch wide.  Cracks must be free of moisture, dust, loose aggregate, and other contaminants.  P & T Products  recommends using oil free compressed air and heat to clean and dry the joint immediately prior to sealing.
