Abstract:Quick-Dry Asphalt Paving Seal (QDAPS) manufactured for Texas Refinery Corp. Fort Worth, Texas.
According to the manufacturer, the primary use for this product is "a moisture resistant preventative maintenance asphalt coating for coating and sealing and protecting black-top surface." A secondary use is to penetrate rejuvenate existing pavements that may have aged excessively due to lack of compaction.
The manufacturer's suggested application rate is 1 1/2 gallons per 100 square feet. This will provide 12.03 mil. thickness dry coverage.
On July 14, 1987, Mr. bill Miller, Independent Consultant, placed the product on the west parking lot of the Oregon State Highway Division Materials Laboratory. This area was judged to be suitable for testing QDAPS. While applying the product he explained about the sealing and penetrating ability of the product and showed us some pavement samples. Mr. Miller told us that full penetration (1 1/2'' or so) should occur in three to four days.
