The dynamic modulus of these samples were measured at frequencies ranging from 0.01 to 25 Hz at temperatures ranging from 5 to 55 ☌ and the mater curve was constructed and used in the pavement design. For material characterization, two types of bituminous mixture sample were fabricated in the laboratory satisfying the Bituminous Concrete grade-2 (BC-2) and Dense Bituminous Macadam grade (DBM) specification of the Ministry of Road Transport and Highways, India. The traffic data required for the design was collected from an existing National Highway and weather data used corresponds to Chennai city. In this investigation, the influence of temperature, vehicle speed and aging on the dynamic modulus of the bituminous mixture was considered and an IRC pavement cross section was analyzed using AASHTOWARE pavement ME design software. However, these factors influences the behavior of bituminous mixture and hence the pavement thickness. All Rights Reserved.In the current practice of flexible pavement design as per Indian Roads Congress (IRC), the influence of cyclic change in pavement temperature, traffic speed and aging on the material behaviour has not been considered. 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.

The impact of underlying concrete slabs on overlay design 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.

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.
