Roadsaver 522
Crafco RoadSaver 522 sealant is a hot-applied asphalt-based product used to seal and fill cracks and joints in both asphalt and Portland cement concrete pavements in cold to very cold climates. RoadSaver 522 is supplied in solid form which when melted and properly applied forms an adhesive flexible compound with high elongation and low stress development at low temperatures, while resisting flow during the summer. RoadSaver 522 can be used in highway, street, and airfield pavements and is applied using either pressure feed Melter applicators or pour pots. At application temperature, RoadSaver 522 is a free flowing, self-leveling product. RoadSaver 522 was developed specifically to perform in temperature extremes and movement conditions that exist in the coldest climates. Over the last 20 years, RoadSaver 522 has proven to be one of the best, if not the best performing crack sealant for very cold climates. Several states and Canadian provinces have adopted specification based on the exceptional performance of RoadSaver 522. Due to the softness of the product RoadSaver 522 is not recommended for use as crack sealant or filler in parking lots or other areas with high foot traffic.
