1. DOT Submittal Requirements A Manufacturer’s Perspective Andrew S. Fulkerson DOT Market Specialist The Euclid Chemical Company

2. What do the following product types have in common? Rapid Setting Cement Based Repair Materials Epoxy Adhesives Non-Shrink Cement Based Grouts

3. They all have an ASTM Standard Specification that gives Pass/Fail Criteria. ASTM C 881 - Epoxy Adhesives ASTM C 928 - Rapid Setting Cement Based Repair Material ASTM C 1107 - Non-Shrink Cement Based Grouts

4. Does this matter? NO!!

5. Most DOT’s require independent laboratory testing for their specification. These testing requirements may include the following: ASTMASTM Modified ASTMModified ASTM State Test MethodsState Test Methods National Transportation Product Evaluation Program (NTPEP)National Transportation Product Evaluation Program (NTPEP)

7. Rapid Hardening Repair for Texas DMS 4655 – Concrete Repair Materials Type A-1-Horizontal Repairs < 4 in. Type A-1-Horizontal Repairs < 4 in. Type A-2 – Horizontal Repairs > 4 in. Type A-2 – Horizontal Repairs > 4 in. Type A-3 – Vertical or Overhead Repairs < 1 in. Type A-3 – Vertical or Overhead Repairs < 1 in. Type A-4 – Vertical or Overhead Repair between 1 in. and 6 in. Type A-4 – Vertical or Overhead Repair between 1 in. and 6 in. Type B – Ultra-Rapid Repairs Type B – Ultra-Rapid Repairs

8. Lets look at the following Section 930 – Materials for Concrete Repair Rapid Hardening Mortar Rapid Hardening Mortar Very Rapid Hardening Mortar Very Rapid Hardening Mortar DMS 4655 – Concrete Repair Materials Type A-1-Horizontal Repairs < 4 in. Type A-1-Horizontal Repairs < 4 in.

9. How do they compare?

12. The differences are as follows: Testing Age and method of Compressive Strength Testing Age and method of Compressive Strength Florida Requires ASTM C 109 @ 3 hrs, 24 hrs, 7D, and 28DFlorida Requires ASTM C 109 @ 3 hrs, 24 hrs, 7D, and 28D Texas requires ASTM C 39 @ 6 hr, 24 hrs, and 28DTexas requires ASTM C 39 @ 6 hr, 24 hrs, and 28D Method for Coefficient of Thermal Expansion Method for Coefficient of Thermal Expansion Florida requires ASTM C 531Florida requires ASTM C 531 Texas requires their own test method which requires higher temperaturesTexas requires their own test method which requires higher temperatures

13. How do they compare? The differences are as follows: Slant Shear Bond Strength ASTM C 882 Slant Shear Bond Strength ASTM C 882 Florida requires 24 hrs and 7 DFlorida requires 24 hrs and 7 D Texas requires 3 D with much higher value and gives a specified concrete mix design for the test cylindersTexas requires 3 D with much higher value and gives a specified concrete mix design for the test cylinders Shrinkage Shrinkage Florida Requires ASTM C 157 using 1 in. beams with a specified curing period that differs from ASTM C 928.Florida Requires ASTM C 157 using 1 in. beams with a specified curing period that differs from ASTM C 928. Texas requires ASTM C 157 using 3 in. beams with another specified curing period that differs from Florida and ASTM C 928Texas requires ASTM C 157 using 3 in. beams with another specified curing period that differs from Florida and ASTM C 928

15. NTPEP NTPEP is a testing program through AASHTO that utilizes the laboratories of certain DOT’s to test a wide array of products. Curing Compounds, chemical admixtures, polymer modified overlayments, and rapid setting repair materials, to name a few. Curing Compounds, chemical admixtures, polymer modified overlayments, and rapid setting repair materials, to name a few. Now lets throw more requirements into the mix!!!!

16. NTPEP Alabama Alabama Colorado Colorado Georgia Georgia Kentucky Kentucky Louisiana Louisiana Maine Maine Missouri Missouri New Jersey New Jersey Tennessee Tennessee Wisconsin Wisconsin All ten of the following States require this testing along with an independent laboratory report to show compliance to their actual specification for Rapid Hardening Concrete Repair.

17. What does this mean for Manufacturer’s 1. Additional cost for product approval 2. Delayed results, NTPEP testing is done once a year and has a two year testing cycle. Colorado requires this testing to be re- started every 3 yrs after approval. Colorado requires this testing to be re- started every 3 yrs after approval. NTPEP requires it every 5 yrs after initial testing is conducted. NTPEP requires it every 5 yrs after initial testing is conducted.

18. One example was given regarding the amount of testing required to get a product approved in multiple State’s. Manufacturer’s must choose the right product to meet the specifications but also to give a return on investment.
