Partnership with CDOT

For the last 14 years, ACPA has partnered with the Colorado Department of Transportation (CDOT) to provide a certification program for concrete pavement inspectors.

Since 2006, any person who inspects concrete pavement on CDOT
projects or projects using CDOT specifications, has been required to
hold a construction inspector certification. An inspector’s thorough
understanding of concrete pavement and the specific construction
processes required for concrete applications can lead to increased
quality and efficiencies at a project site.

Proper inspection plays a
key role in ensuring well-constructed, high quality pavement.
Attendees across the industry

Although CDOT appears in the course title, interested participants
need not be affiliated with CDOT projects to take this course and
earn the certification. By opening the class to all inspectors, ACPA
hopes to increase the understanding of good concrete paving and
inspection practices. Many local agencies have begun requiring
certification of inspectors, as well as contractor QC personnel. This
certification is offered to a wide variety of individuals across the
industry, contractors, consultants, and local agencies.

Updates to the training Program
The program is taught by Sarah Sanders, PE, Pavement Engineer for
the CO/WY Chapter of ACPA, and Val Niculae, PE, CDOT Concrete
and Physical Properties Program Support Engineer. Most classes
also feature guest speakers from the concrete pavement industry to
provide alternate perspectives. An overhaul of the curriculum was
recently completed, and updates were made to include new specifications, equipment, and best practices. The course also provides guidance on completing the required CDOT forms for documentation on a project. The focus of this course is to provide knowledge and understanding for an inspector to ensure proper paving practices are followed on the project site.

Additional topics help the inspector verify that pavement being placed will meet the long-term durability goals that are to be expected with concrete pavement.

The test was re-written to focus on the inspector’s understanding of important concrete paving and inspection topics instead of the ability to memorize specifications. Updated topics include:

• Performance Engineered Concrete Mix Designs
• Paving equipment
• Pavement placement, finishing & joints
• Smoothness Testing
• Contractor QC Plan and QC Notebook
• New testing technologies

2021 Classes
Classes are still being taught in-person following all CDOT COVID-19 Restrictions. Class sizes are limited and are filling up fast. For anyone interested in taking the class, study materials are available from the National Concrete Pavement Technology Center, Federal Highway Administration Concrete Clips series, and many other sources.

Visit the CO/WY ACPA website (www.cowyacpa.org/inspector-certification) for more information and to sign up for 2021 certification dates.

Submittals due January 22, 2021

The Colorado/Wyoming Chapter of ACPA would like to invite you to submit nominations for the 2020 Excellence in Concrete Pavement Awards. These awards are given annually to concrete paving projects of exceptional quality and recognize the owner, engineer, and contractor of each award winning project. All projects in Colorado and Wyoming completed and/or opened to traffic by December 31, 2020 are eligible for consideration.

All project submittals must be completed online at www.acpa.org/acpa-excellence-in-concrete-paving-awards/, which is on the National ACPA website.  If you do not already have a login, you will need to register as a new user in the box labeled “Online Paving Awards Login.”  After registering you will be able to generate your submittal, upload pictures, and edit your submittal until the submission deadline. You can create your submittal in multiple sessions by going to the link and logging back in using your username and password. Once you are logged in, click on “Begin an Application for a New Project.” Make sure to check the appropriate award category for your project and check “Colorado/Wyoming Chapter – ACPA” as the Local Paving Awards Program you are entering.

For consideration, please submit a completed online nomination form by January 22, 2021.  If you have any questions or need further assistance with the online submittal process, please contact Angela Folkestad.

Please join other members of the CO/WY Chapter – ACPA to discuss the goals and initiatives for the Association in the coming year.

Tuesday, October 06
11:00 am – 1:00 pm

Where: 
ACPA Office
6880 S. Yosemite Ct.

Colorado’s concrete paving industry is committed to reducing
Greenhouse Gas (GHG) Emissions in Colorado and around the world.
The concrete paving industry has identified three Stages of
Opportunities for Reducing Greenhouse Gas (GHG) Emissions:
Before Construction, During Construction, After Construction.

Reducing GHG Emissions Before Construction…
Optimizing pavement design and materials selection begins the
process of reducing GHG emissions in the beginning stages of
any pavement’s life. Designing with concrete means designing for
longevity and longevity of pavement life is the primary opportunity
for the reduction of GHG emissions as it allows for less frequent
reconstruction.
The production of cement is often the most referenced item in
regard to CO2 output. One way the concrete pavement and cement
industries have begun addressing this issue is by producing and
using Portland Limestone Cement (PLC) or Type IL. Blending
limestone into the cement reduces the amount of energy required
as well as the amount of CO2 produced. Alternative fuels are also
being used in these plants which burn cleaner than coal and
renewable energy options are being pursued.
Requiring Supplemental Cementitious materials such as Flyash
and Slag Cement utilizes byproducts from coal fire power and steel
production while increasing the durability of concrete pavements.
Specifying optimized gradations reduces the amount of cement
required and the use of recycled concrete can also greatly improve
the opportunity for reduced GHG emissions.

Reducing GHG Emissions During Construction…
Sourcing locally available materials is one of most effective ways to
prioritize sustainability during the construction process. The use of
mobile batch plants decreases the number of trucks hauling long
distances. Having onsite mining operations, 5,200 truck trips can
be avoided when producing 120,000 tons of sand. When recycling
pavement that is removed into 50,000 CY of base 4,200 truck
trips can be saved. All of these contribute to the reduction of
GHG Emissions.
By optimizing phasing of projects, identifying concrete mixtures for
specific situations, and performing nondestructive testing construction can be accelerated which reduces congestion.

Reducing GHG Emissions After Construction…
During its long lifespan, concrete reabsorbs a significant amount of
CO2 through a naturally occurring process called recarbonation.
Pavement preservations and restoration serves the main purpose of
extending the life of the pavement and minimizing disruptions to the
traveling public while maximizing the efficiency of resources.
Diamond grinding is a practice that is often combined with other
Concrete Pavement Repair (CPR) procedures. Diamond grinding can
extend a pavement’s life by 14-17 years per a study performed by
Caltrans. Improved smoothness, texture and reduced noise can all
be anticipated as a result of Diamond Grinding.
Concrete Overlays contribute greatly to pavement preservation and
are a great opportunity for reduced GHG Emissions after initial construction. Concrete overlays efficiently utilize resources and eliminate
the need for disposal of existing pavements. They are cost effective
and are constructed quickly while simultaneously extending the life
of the pavement.
It is imperative to consider all aspects of “use phase” of road construction and identify the areas before, during and after construction
where improvements can be made to create the most sustainable
and reliable roadways possible.
