New Mexico Chapter of ACPA Launches New Website

WELCOME to our new website!  The objective is to provide assistance not only to our members, but especially to all those interested in improving the quality and value of concrete pavements. We believe the employees and consultants of the New Mexico Department of Transportation (NMDOT) and other state, county, municipal and airport authorities, as well as owners and developers of  commercial and industrial pavements will find helpful resource content on this site; to plan, specify, construct and maintain cost-effective Portland cement concrete pavements (PCCP) and Roller- Compacted Concrete (RCC).

We encourage you to explore the site – there a many technical and educational resources that are available from the American Concrete Pavement Association (ACPA), the Concrete Pavement Technology Center (CPTC) and the International Grooving and Grinding Association (IGGA).   We will strive for a continuing effort to provide assistance that YOU seek and will find beneficial.  If you have questions and/or suggestions please respond in the Contact tab.

Re: New Mexico Chapter of American Concrete Pavement Association (NM-ACPA)

       Presented at Commission meeting Gallup NM

 

The contractors and cement companies listed below are pleased to announce the formation of the New Mexico Chapter of the American Concrete Pavement Association (NM-ACPA) as an affiliate of the American Concrete Pavement Association.

 

In the near term and beginning immediately, this Chapter through its members will represent the concrete paving industry in the NMDOT implementation of the Commission Policy CP-91 Alternate Bidding for Pavement Type Selection adopted in December 2013.  In the long term the Chapter will work collaboratively with NMDOT for continuous improvement of quality and value in project delivery, design, construction, and maintenance of concrete pavement in New Mexico.

 

The Chapter affiliation with ACPA (National) is a major benefit to NMDOT and NM-ACPA members, as ACPA is the largest repository of concrete paving resources, including technical and best practice resources available in design, software, construction and maintenance.

 

In an August 6th letter to Governor Martinez copied to Tom Church, Pete Rahn and Ken White, Enrique Escalante, President and CEO of GCC of America thanked the New Mexico Transportation policy leadership team for the adoption of Commission policy CP 91, Alternate Bidding for Pavement Type Selection in December 2013, stating:

 

“We are certain that a comprehensive, consistent and expeditious implementation of CP 91 will benefit the citizens of New Mexico; ultimately developing solid competition between two healthy industries, significantly lowering the life-cycle costs and improving the quality and value of pavements for reconstruction, major rehabilitation and new construction projects provided by both industries in New Mexico.

 

GCC has spent the better part of the last three years in the specific initiative “Ask NMDOT to Reconsider Concrete Pavement.”  With the unanimous (one abstention by Commissioner Wallach for potential conflict of interest) Commission adoption of CP 91 we take in good faith that the NMDOT policy team has reconsidered and now believes that competition from two healthy industries (asphalt and concrete) for pavement type is a good thing for New Mexico; and that full implementation will be accomplished as quickly as possible.

 

With this, GCC will now assume a different role; communicating with NMDOT as a member of a concrete pavement industry coalition. GCC has encouraged the formation of the New Mexico Chapter of the American Concrete Pavement Association ….”

 

Patrick R. Nolan, previously serving as a consultant for GCC in facilitating the GCC Initiative has been named as Organizing and Interim Executive Director for the Chapter.

Pavement Rehabilitation with Unbonded Concrete Overlays

This article for the nm.ACPA.org website was provided courtesy of the COWY Chapter – ACPA.  We plan to post two additional technical articles in early 2017: 1) Thin Bonded Concrete On Asphalt (BCOA), also commonly called 6x6x6 for 6″thick with 6′ longitudinal and 6′ transverse joints in a 12′ travel way placed on a milled asphalt surface; and 2) Concrete Pavement Restoration (CPR) best practices.

As noted in the May 2014 “Guide to Concrete Overlays” published by the National Concrete Pavement Technology Center (CP Tech Center), shrinking budgets and ever-increasing traffic volumes have necessitated the immediate need for engineering strategies to preserve and maintain the nation’s roadways. One such approach is an unbonded concrete overlay.

Unbonded concrete overlays are used to restore structural capacity to existing pavements ranging from moderately to significantly deteriorated. The term “unbonded” simply means that bonding between the overlay and the underlying pavement is not needed to achieve desired performance. Thus, the overlay performs as new pavement and the existing pavement provides a stable base.

There are several benefits of using unbonded concrete overlays, including the solution’s cost-effectiveness. According to the CP Tech Center, “dollar for dollar, they are one of the most effective long-term pavement preservation and major rehabilitation options for existing pavements.” Other benefits of unbonded concrete overlays include their quick construction, ease of maintenance, and sustainability assets.

In general, unbonded resurfacing is highly reliable, offering longer design life than road rehabilitation with asphalt. It has been used successfully by several states, providing on average more than 30 years of good-to-excellent performance, according to the CP Tech Center.

Innovative methods of construction are continuously being explored, and Route D south of Kansas City, MO was the first in the nation to use a fabric bond breaker in 2008. The 3.7 mile long unbonded overlay was constructed in 50 days with a 5” minimum concrete thickness and 6’ x 6’ jointing on a 24’ wide road carrying 9,300 ADT (5% trucks). The new surface has now been serving the traveling public for 8 years, and a 2015 visual distress survey demonstrated that it is performing extremely wellRoute-D-photos

The New Mexico Chapter of ACPA can provide further education on material considerations for long-lasting concrete overlays, and will gladly review potential projects to identify which option(s) are best for your situation. For more information, please contact us.
