Tensile strains at the bottom of the asphalt layer were then computed. Layer moduli were backcalculated from the falling weight deflectometer (FWD) deflection data using the EVERCALC software. Fatigue lives of these sections were also evaluated based on bottom-up cracking.

This study revisited the design of these perpetual pavement sections using now available PerRoad and AASHTOWare Pavement ME Design software to investigate whether the design assumptions were correct. These cracks have been confirmed by full-depth cores. Four perpetual pavement sections were designed and constructed in 2005 and currently are scheduled for rehabilitation for top-down surface cracking. The pavement design begins with a strong, yet flexible bottom layer that resists tensile strain caused by traffic, and thus stops cracks from forming at the bottom of the pavement. All Rights Reserved.Perpetual pavements use multiple, durable asphalt layers to produce a safe, smooth, long-lasting road. ACPA developed a perspectives piece that supports the point that Pavement ME with national calibrations is a good place to start for concrete pavements, particularly for states that don’t have enough data to calibrate.”ĪCPA’s stance has long been that Pavement ME is a better tool than AASHTO 93, and educational efforts by ACPA engineers and others are aimed at providing both the training and tech transfer to support Pavement ME as it continues to evolve.įor the AASHTOWare website, please go to: Ĭopyright © 2022 International Society for Concrete Pavements. Eric said, “This can be a large effort, as many states want to calibrate the program for local performance and also build traffic and materials libraries.

Many states are still in the process of implementing Pavement ME. New design tool for unbonded concrete overlays of concrete pavements.

Updates on various National Cooperative Highway Research Program (NCHRP) Research Studies, which are being evaluated for inclusion into Pavement ME.

For the ISCP October 2020 article on titled “Upgrades to “” - Design Platform Now Better Than Ever!”, please go to: The 3-day web conference also had the opportunity to hear updates on research studies and presentations, including: The web version of the highway pavement thickness design resource will be similar to the web-based pavement design portal, co-developed and currently managed by American Concrete Pavement Association (ACPA), with support from Portland Cement Association (PCA), RMC Research & Education Foundation, and the RCC Pavement Council. One major development was the announcement that AASHTO is planning an online version of Pavement ME sometime in 2022. Canadian user group headed by Tim Smith, Cement Association of Canada (CAC) In addition to the host and sponsoring organizations, the meeting also included ARA is the technical, in-depth, and diversified research, engineering, and technical support services that provide answers to complex and challenging problems in the physical sciences. (ARA) with the opportunity to discuss Pavement ME design developments.

Hosted by APTech, the meeting provided AASHTO and Applied Research Associates, Inc. Mechanistic-Empirical Pavement Design user group AASHTOWare Pavement ME Design is the next generation of AASHTOWare® pavement design software, which builds upon the mechanistic-empirical pavement design guide, and expands and improves the features in the accompanying prototype computational software. A Mechanistic-Empirical Pavement Design user group met the week of December 7, 2020, in a 3-day web conference with about 200 participants, to discuss ongoing developments with AASHTOWare (American Association of State Highway and Transportation Officials) Pavement ME Design, according to Eric Ferrebee, Technical Service Director-ACPA and resident pavement design expert.
