Tack Coat. A. Materials shall conform to the requirements below. For tack coats, a rapid curing cut-back, a cationic emulsified asphalt (CSS-1 or -1h), or an anionic emulsified asphalt (SS-1 or -1h) will be used. Dependent upon the texture of the base and the season of the year that the work is being performed, the Engineer will select the particular grade of the type of asphalt material that will be used. Samples of asphalt material will be tested according to applicable AASHTO or ASTM methods.
1. Rapid Curing Cut-back Asphalt (RC-70, -250, -800 or -3000) shall conform to the requirements of AASHTO M 81.
Tack Coat. When the same storage facility is utilized for Bituminous Materials to be used in Hot Mix Asphaltic Concrete, Bituminous Tack Coat, and/or Surface Treatment, the quantity used for Tack Coat shall be converted to tons (megagrams) and deducted from the quantities for the Bituminous Material used in the Hot Mix Asphaltic Concrete and Surface Treatment.
Tack Coat. Uniformly spray tack coat when placing HMA on paved surfaces. Apply tack coat only to areas to be paved in the same day. Apply tack coat as specified in Table 401.03.02-1: Material Spraying Temp, °F Gallons per Square Yard Season Cut-Back Asphalt: Emulsified Asphalt:
Tack Coat. Furnish CSS-1H, SS-1H, or a PG binder with a minimum high-temperature grade of PG 58 for tack coat binder in accordance with Item 300, “Asphalts, Oils, and Emulsions.” Specialized or preferred tack coat materials may be allowed or required when shown on the plans. Do not dilute emulsified asphalts at the terminal, in the field, or at any other location before use. The Engineer will obtain at least one sample of the tack coat binder per project in accordance with Tex-500-C, Part III, and test it to verify compliance with Item 300, “Asphalts, Oils, and Emulsions.” The Engineer will obtain the sample from the asphalt distributor immediately before use.
Tack Coat. The Applicant will be required to place a tack coat along the exposed vertical edges of asphalt concrete with Type RC of MC 70-250 bituminous tack coat when installing bituminous surfaces.
Tack Coat. A tack coat shall be applied between the existing bituminous surface and the bituminous concrete base course or wearing course. The tack coat may also be ordered by the Engineer between the bituminous base course and wearing course. The surface to be tacked shall be swept clean of all loose particles and dust immediately prior to the application of the tack coat, at the rate of 0.600 Kg/m2 of RC 250 or 0.300 Kg/m2 of residual bitumen from bitumen emulsion.
Tack Coat. Clean the surface before placing the tack coat. The Engineer will set the rate between 0.04 and
Tack Coat. Prior to the placement of surface course asphalt, a tack coat shall be applied over the entire surface of the base course asphalt, at the Owner's expense. The Owner shall clean the base course asphalt to the Town’s satisfaction prior to the placement of the tack coat.
Tack Coat. Furnish CSS-1H, SS-1H, or a PG binder with a minimum high-temperature grade of PG 58 for tack coat binder in accordance with Item 300, “Asphalts, Oils, and Emulsions.” Specialized tack coat materials listed on the Department’s MPL are allowed or required when shown on the plans. Do not dilute emulsified asphalts at the terminal, in the field, or at any other location before use.
