The AASHTOWare Pavement ME Design program is a pavement analysis tool, which is typically used for design purposes through an iterative trial-and-error process. To help the designer with a reasonable starting point in this iterative process, this paper introduces a machine learning method to embrace the recently updated models in AASHTOWare Pavement ME Design software for pavement design. A total number of 79,600 pavement design scenarios (55,800 for flexible pavements and 23,800 for rigid pavements) were performed using the AASHTOWare Pavement ME Design software to consider various design inputs, such as: design life, traffic volume, climate zone, thickness, and modulus of pavement layers. The inputs and outputs of these design scenarios were used to develop the multioutput Random Forests model to simultaneously predict multiple pavement distresses and thicknesses of pavement layers. The results indicate that the multi-output Random Forests model can accurately predict pavement distresses and thicknesses for asphalt and concrete pavements. This tool will simplify pavement design procedure based on the models in the AASHTOWare Pavement ME Design software.
PaveXpress is a free web-based pavement design tool available for use by local agencies, engineers and architects who need a reliable way to quickly determine the necessary pavement thickness for a given section of roadway or project. PaveXpress creates technically sound pavement structural designs for both asphalt and concrete pavements based on widely accepted industry standards from the American Association of State Highway Transportation Officials (AASHTO).
PaveXpress was designed to be an extension of AASHTO 93/98 and has been adopted by public agencies such as the Washington State Department of Transportation as an accepted tool to help assess, scope, and design pavements. New features are added regularly. Since its initial release, PaveXpress has expanded to help users design asphalt overlays, porous asphalt sections, and life cycle cost analyses.
PaveInstruct, a web-based education system, has been developed with video instruction by leading industry experts on the use of PaveXpress. The education modules within PaveInstruct correlate with the design modules in PaveXpress and provide technically sound pavement design and instruction.
Stand alone software version of the pavement design portion of the CE CALC website. Runs on the Windows . NET platform. Performs civil engineering calculations for traffic/road geometry, surveying/earthwork, pavement, concrete floors and unit c
RoadEng is a site and road design software package. It works either as an add-on to other civil design software or as a standalone system. It includes functions for data collection, terrain modelling, contouring, volumes, profiles, sections, and road design.
The online version of the Mechanistic-Empirical Pavement Design Guide (ME-PDG) is available to anyone with Internet access who has an interest in evaluating the guide and software. The pavement design guide is provided in an Adobe PDF format that is read-only, non-save, non-printable, and non-editable. The software can be downloaded for installation on a local drive in executable form, but its copy-protection feature requires access to the Internet to check for a specific file on the Transportation Research Board web server at each use. Certain supporting technical reports from Project 1-37A are available online in an unrestricted PDF format. This version will expire when the guide and software are available from AASHTO or at another time determined by NCHRP. NCHRP may revise this version as necessary and provide updates on the Internet.
Intended Audience: Contractors and Consultants interesting in performing pavement design work for TxDOT. Also anyone interested in learning about the latest pavement evaluation and design tools.
In addition to providing participants with a forum for the exchange of information and ideas, the meeting updated participants on improvements to the ME design procedure and software, provided demonstration-based training on new software features and unique design applications, and discussed the future needs and activities of the ME Users Group.
This study was undertaken to locally calibrate the models in the AASHTOWare Pavement ME Design software and to compare the pavement designs done using the AASHTO 1993 and AASHTOWare Pavement ME Design software for jointed plain concrete pavement (JPCP) sections. Twenty-two newly constructed JPCP projects were selected to calibrate rigid pavement models; 17 of those projects were selected for calibration and five for validation. The traditional split sampling method was followed in calibration. Mechanistic-Empirical Pavement Design Guide (MEPDG)-predicted distresses of road segments were compared with the measured ones. Statistical analysis was performed using the Microsoft Excel statistical toolbox. The JPCP transverse joint faulting model was calibrated using sensitivity analysis and iterative runs of AASHTOWare to determine optimal coefficients that minimized bias. The International Roughness Index (IRI) model was calibrated using the generalized reduced gradient nonlinear optimization technique in Microsoft Excel Solver. The transverse slab cracking model could not be calibrated due to lack of measured cracking data. Eleven prospective and two in-service JPCP sections with varying design traffic levels were reanalyzed using both design methods. The results show that the 1993 AASHTO design guide yielded higher slab thickness than the AASHTOWare Pavement ME Design software for the projects with high traffic level. However, thinner slab thicknesses were obtained by the 1993 Design Guide for the projects with medium and low traffic.
There has been a continuous evolutionary process in asphalt pavement design. In the beginning it was crude and based on past experience. Through research, empirical methods were developed based on materials response to specific loading at the AASHO Road Test. Today, pavement design has progressed to a mechanistic-empirical method. This methodology takes into account the mechanical properties of the individual layers and uses empirical relationships to relate them to performance. The mechanical tests that are used as part of this methodology include dynamic modulus and flow number, which have been shown to correlate with field pavement performance.
This thesis was based on a portion of a research project being conducted at Michigan Technological University (MTU) for the Wisconsin Department of Transportation (WisDOT). The global scope of this project dealt with the development of a library of values as they pertain to the mechanical properties of the asphalt pavement mixtures paved in Wisconsin. Additionally, a comparison with the current associated pavement design to that of the new AASHTO Design Guide was conducted. This thesis describes the development of the current pavement design methodology as well as the associated tests as part of a literature review. This report also details the materials that were sampled from field operations around the state of Wisconsin and their testing preparation and procedures. Testing was conducted on available round robin and three Wisconsin mixtures and the main results of the research were:
For the project, engineers leveraged the ARA-developed AASHTOWare ME Pavement Design software, which helps public and private pavement engineers leverage effective pavement design and analysis tools to improve the cost-effective design and performance of roadway pavements.
The new Tech Corridor reconstruction includes 10 to 12 local traffic lanes and shoulders, all with concrete designed to last 40 years. The reconstructed pavement length represents about eight miles of I-15 that was originally built in the 1970s.
This project is the third major I-15 ARA design/build project. The I-15 work began in 2009 and extended until 2020 with over 38 miles of 10 to 12 lane concrete freeway plus adjacent roadways. Another major Design/Build project that included ARA as the pavement designer is U.S. 89 north of Salt Lake City which is under full-scale construction at the present time (2021). 2ff7e9595c
