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. 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. 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. 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. 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. Prior to placement of the APM, a tack coat shall be applied to all existing concrete and asphalt surfaces. The tack coat shall meet the specification for the emulsified asphalt, consisting of CSS-1h or SS-1h and conform to AASHTO M208 or M140.
B. The tack coat shall be applied at a rate of one-tenth (0.1) to three-tenths (0.3) of a gallon per square yard. The surface receiving the tack coat shall be dry and clean, and dust, debris, and foreign matter shall be removed. Tack coat shall be applied uniformly. The Contractor shall allow the tack coat to cure (dehydrate) prior to the placement of APM. If the tack becomes contaminated during construction, it shall be cleaned, and if necessary, additional tack coat shall be applied and allowed to cure before paving resumes.
Tack Coat. Contact surfaces of manholes, structures, vertical pavement edges, etc. shall be painted with a thin, uniform tack coat just before the material is placed against them. Emulsified tack coat material shall conform to Section 410.
