1039.2.2.3 Epoxy Bonding Agents for Resin Anchor Systems

If a manufacturer requests to have material added to the list of qualified epoxy bonding agents for resin anchor systems, refer to the requirements of Sec 1039.40.4. Following the testing and evaluation, satisfactory products will be placed on the qualified list for bonding agents for dowels.

1039.2.2.4 Epoxy Polymer Concrete

If a manufacturer desires to have material added to the list of qualified Epoxy for Epoxy Polymer Concrete, refer to the requirements of Sec 1039.60.6 and 1039.60.7. Following the testing and evaluation, satisfactory products will be placed on the qualified list for Epoxy for Epoxy Polymer Concrete. A one-quart (1 L) sample of component A and B, accompanied by a technical data sheet and a material safety data sheet is submitted to Construction and Materials for evaluation.

1039.2.3 Basis of Acceptance

1039.2.3.1 Acceptance of Type II or III Epoxy, Epoxy Bonding Agent for Resin Anchor Systems, and Epoxy or Polyester Bonding Agents for Dowels

Material on the list of qualified Type II or III epoxy, epoxy bonding agent for resin anchor systems, or epoxy or polyester bonding agents for dowels may be accepted for maintenance and construction work on the basis of manufacturer's certification and random sampling and testing, when deemed necessary. Furnish the manufacturer's certification to the receiving district to certify that the material supplied is the same formulation as the material tested for manufacturer and brand name qualification. With approval from the engineer, epoxy bonding agents for resin anchor systems not found on the qualified list, Qualified Epoxy Agents for Resin Anchor Systems, may be used in the repair of prestressed concrete members for bridges.

1039.2.3.2 Acceptance of Epoxy Polymer Concrete

Material on the list of qualified epoxy for epoxy polymer concrete may be accepted for construction work on the basis of receipt of notarized certifications, sampling as designated by the engineer, and satisfactory performance in the field. Aggregate that is approved for use in Epoxy Polymer Concrete Overlays by Construction and Materials, and has been recommended for use by the manufacturer of the epoxy, is to be accepted based on required certifications, sampling as designated by the engineer, and satisfactory performance in the field.

1039.2.3.3 Acceptance of Sand for Epoxy Mortar

Sand for epoxy mortar may be accepted in the field on the basis of certification by the supplier that the material is in accordance with all requirements of the specification or any time that conditions warrant additional testing to verify compliance. Furnish the manufacturer's certification to the receiving district. Retain a copy of the certification in the district office.

1039.2.4 Sampling

1039.2.4.1 Sampling of Type II or III Epoxy, Epoxy Bonding Agents for Resin Anchor Systems, Sand for Epoxy Mortar, and Epoxy or Polyester Bonding Agents for Dowels

Take samples any time the certification indicates test results approaching the specification limits or any time that conditions warrant additional testing to verify compliance. When samples are taken, the sample size should be as follows:

Type II Epoxy

Component A - approx. 1 quart (1 L)

Component B - approx. 1 quart (1 L)

Type III Epoxy

Component A - approx. 1 quart (1 L)

Component B - approx. 1 quart (1 L)

Epoxy or Polyester Bonding Agents for Dowels (Bulk)

Approximately 1 quart (1 L) each of Component A & B

Epoxy or Polyester Bonding Agents for Dowels (Cartridge)

1 set of cartridges and a mixing tube

Epoxy Bonding Agents for Resin Anchor Systems (Bulk)

Approximately 1 quart (1 L) each of Component A & B

Epoxy Bonding Agents for Resin Anchor Systems (Cartridge)

1 set of cartridges and a mixing tube

Sand for Epoxy Mortar

Approximately 1 quart (1 L) in a friction top can.

Submit samples of material in bulk form to the Laboratory in friction top cans. Properly identify each can as to component. Submit samples of Bonding Agents for Dowels in cartridge form as received. Use SiteManager and include complete information as to brand name, lot number, and mixing ratio of components. Retain the manufacturer's certification for the lot sampled in the district office.

1039.2.4.2 Sampling of Epoxy Polymer Concrete

1039.2.4.2.1 Epoxy

Take samples when the total quantity of Epoxy Polymer Concrete Overlay, for all projects in combination, exceeds 1200 square yards (1000 square meters). If the total quantity is less than the amount indicated above, the material may be accepted by certification. When sampling and testing is required, take samples at the minimum rate of one set of samples per 2400 square yards (2000 square meters). When samples are taken, the sample size is as follows:

Epoxy for Epoxy Polymer Concrete

Component A - approx. 1 quart (1 L)

Component B - approx. 1 quart (1 L)

Submit samples of material in bulk form to the Laboratory in friction top cans. Properly identify each can as to component. Use SiteManager and include complete information as to brand name, lot number and mixing ratio of components. Retain the manufacturer's certification for the lot sampled in the district office.

1039.2.4.2.2 Aggregate

Take corresponding samples of aggregate for gradation testing when samples of epoxy are required.

1039.3 Report (Records)

If the material is accepted in the field, it is reported through SiteManager. The form must show all pertinent information regarding the material. Retain the certification in the district office. The report is to indicate acceptance, qualified acceptance, or rejection. Include appropriate remarks, as described in The Rounding Off Method, in the report to clarify conditions of acceptance or rejection.

Distribution of reports for materials purchased under a MoDOT purchase order is to be as described in in 1100 Maintenance Materials.
