1017.01 GENERAL. This section covers the material requirements for
Epoxy Resin Adhesives (General Use) and Epoxy Resin Adhesives (Traffic Markers). For anchoring application, the epoxy resin systems shall comply with ASTM C881 (with the exception of the gel time requirement) and ICC -ES AC 308. For crack injection, the minimum gel time shall be 15 minutes.
1017.02 Epoxy Resin Adhesives (General Use).
1017.02.1 General: Epoxy Resin Adhesives shall comply with
AASHTO M 235 (ASTM C881) and the additional requirements of Table 1017-1. Use two component systems in accordance with the manufacturer's recommendations. Epoxy resin adhesives shall be from the Approved Materials List.
1017.02.2 Classifications: Epoxy Resin Adhesives shall be
classified by Type, Grade and Class.
1017.02.2 1 Types:
1.Type I - Use in non -load-bearing application for bonding hardened concrete to hardened concrete and other materials, and as a binder in epoxy mortars or epoxy concretes.
2.Type II - Use in non -load-bearing applications for bonding freshly mixed concrete to hardened concrete.
3.Type III- 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).
4.Type IV - Use in load -bearing applications for bonding hardened concrete to hardened concrete and other materials and as a binder for epoxy mortars and concretes.
5.Type V- Use in load-bearing applications for bonding freshly mixed concrete to hardened concrete.
6.Type VI- Use for bonding and sealing segmental precast elements, as in segment -by-segment erection and for span -by-span erection when temporary post tensioning is applied.
7.Type VII- Use as a non -stress-carrying sealer for segmental precast elements when temporary post tensioning is not applied, as in span-by-span erection. Note 1—Epoxy resin systems will adhere to a wide variety of materials, including wood, metals, masonry, and most plastics. Polyethylene, TFE - fluorocarbon, cellophane, and greased or waxed surfaces are among the few materials to which these systems will not adhere.
1017.02.2 2 Grades: Three grades of systems are defined
according to their flow characteristics and are distinguished by the viscosity and consistency requirements of AASHTO M 235, Table 1. Grade 1 - Low viscosity. Grade 2 - Medium viscosity. Grade 3 - Non-sagging consistency.
1017.02.2 3 Classes: Classes A, B, and C are defined for Types
I through V, and Classes D, E, and F are defined for Types VI and VII, in accordance with the range of temperatures for which they are suitable. Class A - Use below 40°F (4°C), with the lowest allowable temperature to be defined by the manufacturer of the product. Class B - Use between 40 and 60°F (4 and 15°C). Class C - Use above 60°F (15°C), with the highest allowable temperature to be defined by the manufacturer of the product. Class D - Use between 40 and 65°F (4 and 18°C) for Type VI and VII applications. Class E - Use between 60 and 80°F (15 and 30°C) for Type VI and VII applications. Class F - Use above 75°F (25°C) for Type VI and VII applications, with the highest allowable temperature to be defined by the man ufacturer of the product.

1017.03 Epoxy Resin Adhesives (Traffic Markers).
1017.03.1 General: Epoxy Resin Adhesives for bonding traffic
markers shall comply with AASHTO M 237, Type I and Type II, and the requirements of Table 1017-2. Use two component systems in accordance with the manufacturer's recommendations. Use epoxy resin adhesives from the Approved Materials List.
1017.03.2 Classifications: Epoxy Resin Adhesives shall be
classified by Types.
1017.03.2 1 Types:
Type I - Rapid Setting, High Viscosity, Epoxy Adhesive. This type of adhesive provides rapid adherence of traffic markers to the surface of the pavement. Type II- Standard Setting, High Viscosity, Epoxy Adhesive. This type of adhesive is recommended for adherence of traffic markers to pavement surfaces when rapid set is not required.
