Straight Facts About Jointed Precast Concrete Pavements: New Developments and Future Directions

The following links are for the recorded version, as well as the combined presentations for the ACPA/NPCA webinar, “Straight Facts about Jointed Precast Concrete Pavements: New Developments and Future Directions” (July 15, 2014).   

Due to technical difficulties, some registrants did not receive the password for the live presentation.   The same issue impacted the beginning of the webinar, and so approximately 10 to 15 minutes of the recorded presentation are missing.   We regret the inconvenience, but are providing both the full presentation and the final 90% of the recorded presentation.

ACPA Offers LCCA Publication in Spanish

http://www.acpa.org/bookstore

ACPA’s life-cycle cost analysis publication (EB011) is now available in Spanish, thanks to the Cement and Concrete Institute of Chile.  The publication, “Análisis del costo del EB011 - Análisis del Costo del Ciclo de Vida_Page_001 de vida: Una herramienta para evaluar mejor las inversiones y decisiones técnicas en pavimentación,” is available at http://www.acpa.org/bookstore.   To find the publication, select “Top 100 products” and enter the keyword “ciclio.”

(English) This  publication begins by discussing LCCA in general terms and then providing detailed steps for conducting a single-project LCCA.  Examples with detailed analyses are provided for LCCAs of a local road, highway, and airport pavement.  The document also covers some applications and extensions of LCCA, such as the “mix of fixes” concept, sustainability in the context of LCCA, the role of LCCA in pavement type selection, the impact of material quantity specifications on LCCA results, and total ownership cost.  The appendices include a deterministic LCCA worksheet, a discussion on historical oil price trends and volatility, and all current federal policies on pavement type selection.

(Espanol) Este boletín técnico presenta los conceptos del análisis del costo del ciclo de vida (LCCA) con la finalidad de poder comparar alternativas de diseño de pavimentos equivalentes desde el punto de vista económico.  Se explican odos los factores que deberían ser considerados en un análisis económico y se entregan pautas para la selección de los valores de los factores sensibles del LCCA. Se presentan ejemplos de un LCCA de proyectos únicos para una calle urbana, una carretera y una pista de aterrizaje. También se discuten algunos temas avanzados del LCCA, como el análisis probabilístico, el impacto de la vida de servicio del pavimento en la red, el rol del LCCA en la selección del tipo de pavimentación y consideraciones relacionadas con la volatilidad de los precios de los materiales.

The engineering bulletin cost is $25 for ACPA members; $100 for non-members.

ACPA Strategic Advisory Committee Explores Short Slab Pavements

At a meeting on Wednesday, July 16, ACPA took another step in a careful evaluation of short-slab concrete pavement design technology. The Strategic Advisory Committee reviewed a proposal outlining how the Association might engage in further education of the pavement community on this new technology.  

Short-slab pavement design has been shown to address several challenges with pavement performance, including curling and warping, as well as cost-competitiveness.  The engineering behind short-slab designs could represent a major engineering evolution  for the industry. Independent pavement design and research experts have validated the technical approach, but some questions remain surrounding proprietary aspects of the designs.  

The Strategic Advisory Committee recommended to the ACPA Board of Directors the adoption of the concept of joint spacing as a thickness design variable in June 2013.  The concept is for joint spacing as a thickness design input versus leaving joint spacing as a selected feature after thickness is determined.

Also at question is whether ACPA can aid in overcoming the traditional thinking that sometimes limits technology transfer and implementation among public and private sector agency/owners.

No decisions were made at the July 16 meeting, and so, the Strategic Advisory Committee will continue to evaluate how ACPA could include short slab design technology in their technical and promotional programs.

Reminder: Register Today for Airfield Concrete Pavements Workshop

PrintRegistration  

There’s still time to register for ACPA’s comprehensive, three-day workshop covering best practices in airfield pavement design and construction.  The course will be held October 14 through 16 at ACPA’s Rosemont, Ill.-headquarters, located at 9450 W. Bryn Mawr Ave., Rosemont, Illinois.   This special training event will be held in the 3rd floor conference room.

The curriculum is well suited for contractors; airport owners and owners’ representatives; consultants/engineers; inspectors; military engineers; Federal Aviation Administration (FAA) personnel, and others with an interest in designing, constructing, and maintaining quality concrete pavements for commercial airports and military airfield applications.

Leading experts from the American Concrete Pavement Association, the Federal Aviation Administration, and other companies in the airport construction community will present information and lead open discussions.

Program Overview
In addition to providing comprehensive information about airport pavement design & construction, it will also cover various specifications (i.e., P-501, Unified Facilities Guide Specifications, etc.); advisory circulars; engineering briefs; and other resources.  


Just a few of the topic areas that will be covered in the workshop include foundation support, jointing, concrete mixtures, stockpiling, concrete plant management, acceptance criteria, smoothness, and much more.

Professional Development Hours
Participants will have the opportunity to earn up to 20 professional development hours (PDH’s) for the successful completion of the course.  ACPA encourages participants to confirm the acceptance of ACPA-issued PDH’s with licensing organizations in their state/province.

Registration Information
Registration for this three-day course is $750 for ACPA members, $900 for non-members, and $500 for government employees.
