Specifications include, but are not limited to: B.1 Asphaltic Material (1) Furnish asphaltic materials for seal coats and fog seals conforming to section 455 of the standard specifications. (2) Provide CRS‐2P or HFRS‐2P, asphaltic material for seal coat. Provide CRS‐2P or HFRS‐ 2P, asphaltic material for fog seal when fog seal is applied in conjunction with seal coat. The CRS‐2P and HFRS‐2P, asphaltic material for seal coat, and for fog sealing, shall meet the following requirements for the type and grade specified. Only Asphaltic Material supplied from a certified source is approved for use. (3) The asphalt emulsion shall be compatible with the cover aggregate. Provide the supplier of the asphalt emulsion test results from the aggregate sample. The supplier of the emulsion will provide a certification that the emulsion is compatible with the aggregate. (4) The emulsified asphalt shall meet the requirements of AASHTO M‐316 subject to the following modification: a) Polymer‐modified cationic emulsified asphalt, (CRS‐2P), and polymer‐modified anionic emulsified asphalt, (HFRS‐2P) shall be produced by using polymer modified base asphalt only. The use of Latex modification shall not be allowed. Any emulsion not meeting this requirement shall not be used. B.2 Aggregate (1) Provide aggregate conforming to section 475 of the standard specifications. Use aggregates, uniform in quality and free from wood, bark, roots, and other deleterious materials. Furnish aggregate conforming to the following table: Percent Passing By Weight Sieve Size #1 #2 #3 3/8 inch (9.5mm) 100 100 100 #4 (4.75mm) 90‐100 90‐100 85‐100 #8 (2.36mm) 45‐75 5‐10 10‐40 #16 (1.19mm) ‐ ‐ 0‐10 #40 (.425mm) 0‐8 ‐ ‐ #200 (.075mm) 0‐2 0‐1 0‐1 (2) At least two weeks before construction provide aggregate gradation to the engineer for review (3) The engineer may take a sample of the aggregate and re‐test the gradation of the cover aggregate during seal coat operations. B.3 Water Use potable water, compatible with the seal coat. B.4 Seal Coat Design (1) Provide the following to the engineer at least two weeks beforebeginning construction: a) Seal coat aggregate design application rate (Lbs/SY), b) Asphalt emulsion design application rate (Gal/SY), and c) Source(s) of aggregate and asphalt emulsion. (2) The department may postpone the start of work until receipt of the seal coat design and approval by the engineer. (3) If the aggregate material specified in Table 1 is unavailable or is cost prohibitive to obtain, the Contractor may submit a proposed seal coat design prior to providing a quote. The proposed design should include a listing of projects and roadways where the seal coat design has been utilized within the last four years. The proposed alternative design will be reviewed by the engineer
