3.0 SCOPE OF SERVICES:

The scope of work consists of providing all plant, labor, equipment supplies, material, transportation, handling, and storage, and performing all operations necessary to complete the application of seal coat of asphalt cement for roads and parking surfaces located at the National Geodetic Survey’s Training Center & Laboratory facility located at 15351 Office Drive, Woodford, VA 22580. There is approximately 29000 combined square feet of road and parking surface area requiring slurry seal application associated with Office Drive and associated parking areas. The associated tasks include:

4.0 MATERIALS:

Materials should meet standard Industry specification for Asphalt Based Pavement Sealers. See attached ASTM International Standard Specification for Asphalt Emulstion Pavement Sealer (Mineral Colloid or Chemically Stabilized Type), Designation: D8099/D8099M-17.

5.0 CONSTRUCTION METHODS:

5.1 SURFACE PREPARATION

Purpose: The surface to receive asphalt sealcoat must be free of all foreign material and dry immediately prior to sealcoat application.

Contractor Shall:

Clean surface by air blowing or mechanical sweeping, or other as approved by on-site property contact.

Pretreatment and scrap any oil / grease spots to insure prior adhesion of seal coating.

Cleaning of such areas can be scraping, burning and/or chemical cleaning. (Where chemical cleaning is to be the method of cleaning MSDA sheets on all chemicals must be submitted to the owner prior to use.)

Remove any vegetation in cracks and treat the areas with a non-oil base soil sterilant prior to treating the crack as outlined in this document.

Cracks in excess of ¼ inch, but less than 1 inch in width must be properly sealed, in a fashion consistent to the manufacture’s recommendations of the sealcoat product, prior to seal coat application. Crack filler shall be hot or cold applied product designed to be compatible with the seal coating and meet current MDOT standards.

5.2 APPLICATION:

Purpose: The sealer must be applied to sound pavements. It is not a method of resurfacing deteriorated pavement. The sealer is specifically formulated to shield against the drying action of the sun, resist damage from oil and gasoline leakage and prevent water penetration. The sealer can extend the life of the pavement IF applied to sound pavement on an as needed schedule. For optimal protection Rate (undiluted material) 2 coats at 30 gallons per 100 square feet (15 gallons each coat)

First application of the seal coat must be dry prior to the second application of seal coat.

Sealer should not be applied unless pavement temperature is at least 50 ºF (10 ºC) and the air temperature is 50 ºF (10 ºC) and rising.

Sealer should not be applied during rainy or wet weather, or when rain is anticipated within eight hours after application is completed.

Sealer should not be applied to hot surfaces under the summer sun (over 90 ºF, ambient) without first cooling the surface with clean water. Water should dampen the surface without leaving puddles.

Seal coat shall be applied uniformly, free of lumps and other inconsistencies, leaving no ridge or uncoated areas.

Application method shall be by an approved method as recommended by the manufacture of the product being applied.
