DOT Submittal
Requirements
A Manufacturer’s Perspective
Andrew S. Fulkerson
DOT Market Specialist
The Euclid Chemical Company
What do the following product types
have in common?
Rapid Setting Cement Based Repair Materials
Epoxy Adhesives
Non-Shrink Cement Based Grouts
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
Does this matter?
NO!!
Most DOT’s require independent
laboratory testing for their
specification.
These testing requirements may include the
following:
• ASTM
• Modified ASTM
• State Test Methods
• National Transportation Product
Evaluation Program (NTPEP)
Rapid Hardening Repair for Florida
Section 930 – Materials for Concrete Repair



Rapid Hardening Mortar
Very Rapid Hardening Mortar
MAPC (High Stress Areas)
Rapid Hardening Repair for Texas
DMS 4655 – Concrete Repair Materials





Type A-1-Horizontal Repairs < 4 in.
Type A-2 – Horizontal Repairs > 4 in.
Type A-3 – Vertical or Overhead Repairs <
1 in.
Type A-4 – Vertical or Overhead Repair
between 1 in. and 6 in.
Type B – Ultra-Rapid Repairs
Lets look at the following
Section 930 – Materials for Concrete Repair


Rapid Hardening Mortar
Very Rapid Hardening Mortar
DMS 4655 – Concrete Repair Materials

Type A-1-Horizontal Repairs < 4 in.
How do they compare?
How do they compare?
The differences are as follows:

Testing Age and method of Compressive Strength
• Florida Requires ASTM C 109 @ 3 hrs, 24 hrs, 7D, and
28D
• Texas requires ASTM C 39 @ 6 hr, 24 hrs, and 28D

Method for Coefficient of Thermal Expansion
• Florida requires ASTM C 531
• Texas requires their own test method which requires
higher temperatures
How do they compare?
The differences are as follows:

Slant Shear Bond Strength ASTM C 882
• Florida requires 24 hrs and 7 D
• Texas requires 3 D with much higher value and gives a
specified concrete mix design for the test cylinders

Shrinkage
• 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
928
Other Requirements Outside of
Testing







Packaging
Lot numbering
Born on Date vs. Use By Date
Shelf Life
Recertification
Re-testing frequencies
Certification Letter on each Lot
NTPEP
Now lets throw more requirements into the
mix!!!!
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.
NTPEP
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.





Alabama
Colorado
Georgia
Kentucky
Louisiana



Maine
Missouri
New Jersey
Tennessee
Wisconsin
What does this mean for
Manufacturer’s
1.
2.
Additional cost for product approval
Delayed results, NTPEP testing is done
once a year and has a two year testing
cycle.


Colorado requires this testing to be restarted every 3 yrs after approval.
NTPEP requires it every 5 yrs after initial
testing is conducted.
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.
