Section 32 01 16 73 Coal Tar Concentrate Pavement Sealer
Description of Work Cost shall cover the furnishing and installing of coal tar sealer on airfield pavements, roads, streets, parking areas, and other general applications. Installation procedures shall be in accordance with the product manufacturer’s recommendations. Demolition and removals of materials shall be as required to support the work.
Submittals required for each type of product indicated.
Products:
Product should be a highly concentrated material intended to be mixed with water and mineral aggregate to form a ready to use pavement sealer. (Polymer additives can be added as an option) Based on 100 gallons for ease of calculations) Coal Tar Concentrate Sealer 100 gals Water 25-50 gals Sealer V. M. Polymer 1-2 gal (optional) Sand 300-500 lbs (30-70 mesh AFS rating)
Physical/Chemical Properties: Coal Tar Concentrate is a premium quality pavement sealer that meets the following material requirements when tested in accordance with ASTM D 140, ASTM D 466, ASTM D 490, ASTM B117, ASTM D 529, ASTM D 2939, and ASTM D244 procedures. Material shall be homogenous and show no separation or coagulation that cannot be overcome by moderate stirring.

Installation Preparatory Work:
The asphalt surface must be structurally sound, surface cured, and free from all loose or foreign matter prior to the application.
Methods:
Place with mechanical equipment specifically designed for this purpose. Due to the heavy bodied nature of the slurry-mixed, application by means of specialized equipment is required. This equipment can be of two types, high volume positive displacement airless spray or mechanical squeegee. Both types must be capable of keeping material thoroughly mixed and homogenous throughout the application process by continuous agitation. All equipment used must be capable of supplying a sufficient quantity of material for uniform application over the entire width of the application mechanism to provide a uniformly coated surface.
Limitations:
Products shall not be applied when temperatures is expected to drop below 60°F or stricter product requirements at any time within a 24 hour period after applications
