ASSHTO Compliant

Our Tip Top Tack Coat meets and or exceeds the ASSHTO specifications set forth in there manual in Section 412. — ASPHALT TACK COAT

In sub section 702.03 for Emulsified Asphalt. It has to Conform to Subsection 702.04. When specified for tack coat, an equivalent anionic grade emulsion may be substituted for a cationic grade and vice versa. The sieve test in AASHTO M 140 and M 208 is not required.

(a) Anionic emulsions. Conform to AASHTO M 140. For RS-1h and RS-2h, conform to AASHTO M 140 for RS-1 and RS-2, except conform the following for the penetration on the residue. Ductility, 25 ºC, 50 mm/min, AASHTO T 51 40 mm min.
