• Type II—For use in non-load bearing applications, bonding freshly mixed concrete to hardened concrete.

• Type III—For use in bonding skid-resistant materials to hardened concrete and as a binder in epoxy mortars or epoxy concretes used on traffic bearing surfaces (or surfaces subject to thermal or mechanical movements).

• Type V—For use in load bearing applications, bonding fresh concrete to hardened concrete.

• Grade 1—Low viscosity

• Grade 2—Medium viscosity

• Grade 3—Non-sagging consistency

• Class A—For use below 40F, to the lowest allowable temperature defined by the manufacturer.

• Class B—For use between 40F and 60F

• Class C—For use above 60F, to the highest allowable temperature defined by the manufacturer.

706.2Other Bonding Compound—Provide a bonding compound with a minimum 14 -day bond strength

of 1,500 pounds per square inch as tested according to ASTM C882. Obtain compound from a manufacturer listed in Bulletin 15. Certify as specified in Section 106.03(b)3 . Submit a copy of the manufacturer's recommendations for proper application to the Representative. Apply the compound according to the manufacturer’s recommendations.
