Use for installing dowels into hardened portland cement concrete or hardened Portland cement concrete to hardened Portland cement concrete. A) Type V. Use for bonding plastic portland cement concrete to hardened portland cement concrete.

.01 Epoxy-Sand Slurry for Concrete Bridge Deck Overlays. Conform to

ASTM C 881, Type III or AASHTO M 200, Class II.

.02 Reinforcing Bar Grout Adhesives. The Department will allow reinforcing

bar grout adhesives, from the Department’s List of Approved Materials, as an alternate to Type IV epoxies for doweling reinforcing bars into hardened concrete.

A) Category I. Conform to KM 64-209 utilizing a maximum one-hour cure time. B) Category II. Conform to KM 64-209 utilizing a maximum 24-hour cure time.

.03 Structural Adhesives with Extended Contact Time. The Department

will allow structural adhesives, from the Department’s List of Approved Materials, as an alternate to Type V epoxies for bonding plastic portland cement to hardened portland cement concrete.

826.02APPROVAL. The Department will approve epoxy resin systems based on review

of required independent laboratory data and Department conducted testing. Submit independent laboratory data conducted within one year of the date of product submittal for Department approval. Obtain Department approval for each epoxy resin system every five years.

.01 ASTM C881 Epoxy. The Department will approve ASTM C881 epoxy

for Type, Class, and Grade based on the ma nufacturer’s submission of independent laboratory data showing the actual test values for the ASTM specification requirements and submission of a product sample from a production lot for testing. C881 Type IV analysis shall include re-bar pull testing in accordance with KM64-209.

.02 AASHTO M 200. The Department will approve AASHTO M200 epoxy

based on the manufacturer’s submission of independent laboratory data showing the actual test values for the AASHTO M 200 specification requirements for Class II and submission of a product sample from a production lot.

.03 Reinforcing Bar Grout Adhesives. The Department will approve non-

epoxy Reinforcing Bar Grout Adhesives based on testing conducted by the Department in accordance with KM64-209.

.04 Structural Adhesives with Extended Contact Time. The Department

will approve Structural Adhesives with Exte nded Contact Time based on the manufacturer’s submission of independent laboratory data showing the actual test values for the ASTM C881 specification requirements for Type V, with the following modifications and submission of a product sample from a production lot.

A) Gel Time (Minimum) 90 Minutes

B) Compressive Strength (ASTM C109) (Minimum) 7-Day 5,000 psi

A) Bond Strength (ASTM C882 Modified*) (Minimum) 14-Days 0 Hour Contact Time 2,000 psi 16 Hours Contact Time 1,500 psi

*ASTM C882 is modified to allow for 16 hours contact time. Contact time is the time allowed between application of the bonding agent and placement of the plastic concrete.

826.03PACKAGING. Package the 2 components in separate containers. Identify the

containers as “Component A - Contains Epoxy Resin” and “Component B - Contains Hardener.” Include on the container the following information:

1) Type, mixing directions, and usable temperature range. 2) Name of the Manufacturer. 3) Lot or batch number. 4) Date of packaging. 5) Type of pigmentation. 6) Quantity contained in pounds and gallons. 7) Potential hazards according to the Federal Hazardous Products Labeling Act.

826.04CERTIFICATION. Submit manufacturer’s certification stating conformance to

the requirements of this Section for each shipment of approved epoxy resin system delivered for use on projects. Clearly state the manufacturer, product name, type, class, grade, and category; as appropriate for each epoxy resin system as listed in the Department’s List of Approved Materials. Identify the lot number(s), expiration date, and quantity of each component of epoxy resin system.

826.05ACCEPTANCE. The Department will accept epoxy resin systems based on

verification of inclusion on the Department’s List of Approved Materials, compliance of the manufacturers certification and verification the epoxy resin system has not exceeded the expiration date. The Department reserves the right to sample and test epoxy resin systems, at the Engineer’s discretion, in accordance with the Department’s Field Sampling and Testing Manual.

SECTION 827 EROSION CONTROL MATERIALS

827.01DESCRIPTION. This section covers the requirements for various materials used

for erosion control.

827.02AGRICULTURAL LIMESTONE. Conform to the requirements and provisions

of the Kentucky Department of Agriculture. The Department of Agriculture furnishes a test report and any required weight penalties to each agricultural limestone producer. Furnish the Engineer with a copy of the test report, curr ent within 9 months, as the basis of approval. The Engineer may sample any agricultural l imestone that appears to be of questionable quality upon visual inspection.

827.03FERTILIZER. Provide commercial fertilizer that complies with the Kentucky

Fertilizer Law, and contains the plant nutrien ts of nitrogen, available phosphoric acid, and soluble potash as specified in the Contract. Ensure that bagged fertilizer displays the following information on the bag or on a sticker or tag attached to the bag: 1) Net Weight 2) Brand and Grade 3) Guaranteed Analysis 4) Name and Address of Manufacturer

Ensure that the manufacturer includes a statement with the bulk fertilizer (dry or liquid) that contains the same information required for the bagged fertilizer. Provide either bagged or bulk (dry or liquid) fertilizer manufactured and sold under the jurisdiction of the Division of Regulatory Services of the University of Kentucky Agricultural Experiment Station. The Department must sample, test, and approve any other fertilizer prior to its use.

827.04SEED. Conform to the requirements outlined in the . “Kentucky Seed Law and

Provisions for Seed Certification in Kentucky” and the “Regulations under the Kentucky Seed Law”, with following exceptions:

1) Obtain seed only through registered dealers that are permitted for labeling of seed. 2) Ensure all deliveries and shipments of premixed seed are accompanied with a master blend sheet. 3) Ensure all bags and containers have an acceptable seed tag attached. 4) The Department may sample the seed at the job site at any time.
