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: Table 401.03.02-1 Tack Coat Application Material Spraying Temp, °F Gallons per Square Yard Season Cut-Back Asphalt: RC-70 120 to 190 0.05 to 0.15 Oct 15 to Apr 15 Emulsified Asphalt: RS-1 70 to 140 0.05 to 0.15 All year CRS-1 125 to 185 0.05 to 0.15 All year SS-1, SS-1h 70 to 140 0.05 to 0.15 All year CSS-1, CSS-1h 70 to 140 0.05 to 0.15 All year Correct uncoated or lightly coated areas. Blot areas showing an excess of tack coat with sand or other similar material. Remove blotting material before paving. Ensure that the material is not streaked or ribboned. Before paving, allow tack coat to cure to a condition that is tacky to the touch.
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.
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.
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.
Tack Coat. A tack coat of emulsified asphalt, RS-1, Item #409.15 shall be applied to any existing pavement at a rate of approximately 0.025 G/SY, and on milled pavement approximately 0.05 G/SY, prior to placing a new course. A fog coat of emulsified asphalt shall be applied between shim / intermediate course and the surface course, at a rate not to exceed 0.025 G/SY. Tack used between layers of pavement will be paid for at the contract unit price for Item 409.15 Bituminous Tack Coat.

Field conditions may warrant the use of additional signs as determined by the Resident. Road work Next x Miles Road work 000 Xxxx Xxx Xxxx Work Work Area At each work site, signs and channelizing devices shall be used as directed by the Resident. Signs include: Road Work xxxx ¹ One Lane Road Ahead Flagger Sign Other typical signs include: Be Prepared to Stop Low Shoulder Bump Pavement Ends The above lists of Approach signs and Work Area signs are representative of the contract Requirements. Other sign legends may be required. The Contractor shall conduct their operations in such a manner that the roadway will not be restricted to one lane for more than 800 m [2,500 ft] at each work area. To encourage quality paving in warm-weather conditions, the length can be extended to 4,000 ft depending on the traffic impacts. Where more than one work area restricts traffic to one lane operation, these work areas shall be separated by at least 1.6 km [1 mile] of two way operation. Temporary Centerline A temporary centerline shall be placed each day on all new pavement to be used by traffic. The temporary centerline, when specified of reflectorized traffic paint, shall conform to the standard marking patterns used for permanent markings. Failure to apply a temporary centerline daily will result in a Traffic Control Violation and suspension of paving operations until temporary markers are applied to all previously placed pavement. ¹ “Road Work Ahead” to be used in mobile operations and “Road Work xx ft” to be used in stationary operations as directed by the Resident. 3DJH RI 018080.10
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. 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 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
