CP Tech Center Posts Concrete Distress Guide

Understanding, preventing and repairing distresses in concrete pavements has always been challenging, but thanks to a new guide, the task will now be much easier.

Published by the CP Tech Center, the “Guide for Concrete Pavement Distress Assessments and Solutions” allows readers to match various distresses with effective solutions. The 470-page guide is divided into two major sections that cover full-depth concrete pavements and concrete overlays, as well as a third section that covers, “Field Evaluation and Laboratory Testing Procedures.”

The guide is written for agency personnel and consulting engineers responsible for managing concrete pavement assets. Contractors also may find the guide to be useful as a quick reference or for training. Each distress type in the guide includes useful information that includes a description, severity, causes, evaluation, treatment and repairs, and references.

The manual was developed as part of a Federal Highway Administration (FHWA) cooperative agreement to support more sustainable concrete pavement technical solutions. To view/download the guide as a PDF, click here. To download the guide as an e-pub, click here.

CP Tech Center Awarded FHWA Cooperative Agreement

The National Concrete Pavement Technology Center (CP Tech Center) has received a cooperative agreement by the Federal Highway Administration.  The cooperative agreement was funded under the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) program.

AID-PT was the result of a legislative provision championed by ACPA and first included in the Moving Ahead for Progress in the 21st Century Act (MAP 21).  The program was also included in the Fixing America’s Surface Transportation Act (FAST Act), signed into law in December 2015.

AID-PT created both a mechanism and funding for the delivery of pavement technology for both the concrete- and asphalt-pavement industries. Since its inception, the program has resulted in benefits to the concrete pavement community, including other contracts and cooperative agreements with the National Concrete Pavement Technology Center (CP Tech Center), an ACPA Technology Partner.

AID-PT has had direct and tangible benefits for highway agencies, contractors, consultants, and academia. Concrete overlays and performance-engineered concrete mixtures (including the use of recycled concrete aggregates) are two technology initiatives that have received support in the form of outreach, education & training, and technology transfer.  Additional information about his cooperative agreement will be presented at ACPA’s 55th annual meeting next week.

CP Tech Center Offers PEM Resource

Performance engineered mixtures (PEMs) are gaining momentum and the attention of the concrete construction community, including owners and contractors. 

For contractors and others interested in more information about PEM, The National Concrete Pavement Technology Center (CP Tech Center) has published “Performance Engineered Mixtures for Contractors,” an 8-page tech brief written by Peter Taylor.

The tech brief provides guidance on properties, processes and recommended tests for the laboratory and the field. It also includes detailed information about tests available to gauge workability, air void system, unit weight (density), strength development, and transport qualities .

The brief also cites recommended tests for quality control and agency acceptance by the agency involved. This publication was sponsored by the FHWA, the National Pooled Fund Study TPF-5(368), and the concrete industry. To view or download the document, click here.

ACPA Presents at Concrete Pavement Workshop

In support of the Cement Association of Canada, an ACPA affiliate, Leif Wathne participated in the 2018 BC Concrete Pavements Workshop in Burnaby, BC, last week. He spoke about competition, asset management, and on concrete overlays.  In the concrete overlay presentation, Wathne cited several resources, including the CP Tech Center’s “Guide to Overlays,”  which is just one of a large collection of manuals & guidelines, reports, tech briefs and other overlay resources the Center offers. 

Workshop participants included industry and agency officials, Wathne says, noting that Omar Swei, Assistant Professor at the University of British Columbia, presented on improving infrastructure design and maintenance. LCCA and project examples from across Western Canada also were focal points of the workshop.

Wathne says, “An ongoing dialogue with the concrete and cement industry in BC can help agencies better understand what steps to take to start benefitting from inter-industry competition.”

ACPA Board Affirms Association Directions

The ACPA Board took several important actions during its third quarter meeting in Rosemont on October 11.  The board affirmed its support of the advancement of a new promotion plan developed jointly with Portland Cement Association. The plan is currently being refined and will be discussed with the Portland Cement Association Board later this month.

The ACPA Board also provisionally accepted a 2019 draft budget plan prepared by the Budget & Finance Committee, with the understanding that outstanding questions will be clarified between now and the annual meeting on Nov. 27-29.  Adjustments may be made as needed during the interim period, with final acceptance anticipated at the next board of directors meeting Nov. 29.  The Association anticipates a budget of $3.88 million to support pavement promotion.

In addition, directors affirmed the Association’s support of the CP Tech Center’s efforts on the performance engineered mixtures (PEM) research/development program and considered a new proposal from the Aggregate & Ready Mix Association of Minnesota to formalize a chapter affiliation agreement, supporting pavement promotion in the state.
