Available in PDF, EPUB and Kindle. Book excerpt: Currently, TxDOT uses the AASHTO 93 design guide for the slab thickness design of continuously reinforced concrete pavement (CRCP). The AASHTO 93 design guide was developed based on the AASHTO road test, where JCP (jointed plain concrete pavement) was the major pavement evaluated and CRCP was not included. From a purely technical standpoint, the AASHTO 93 design guide is not appropriate for the design of CRCP. With ever increasing traffic on major highways in Texas where CRCP is widely used, there is a need for a more mechanistic empirical (ME) based pavement design procedure for CRCP. An ME based pavement design method will allow TxDOT to optimize pavement structures to best utilize the limited financial resources available.To develop an ME-based CRCP design procedure, the mechanism of punch outs was identified by field evaluations of CRCP, which included coring, deflection testing using falling weight deflectometer (FWD), and other nondestructive testing. Once the punch out mechanism was identified, mechanistic modeling was performed using a three dimensional finite element program. Another important element in the ME based pavement design procedures is the accuracy of a transfer function. A transfer function was developed using the data from TxDOT PMIS. A CRCP design program based on ME principles was developed with a User Guide for the program. In the program, the effect of nonuniformity of subbase support, or the effect of erosion, was not directly addressed. From a theoretical standpoint, the effect is included in a transfer function. Sensitivity analysis was conducted to evaluate the effects of input variables and the reasonableness of the results. Since the reasonableness of TxCRCP ME depends on the accuracy of transfer function, further efforts are recommended to refine the transfer function by collecting more accurate information on traffic, construction information and distress data. Once an accurate transfer function is developed, further sensitivity analysis will be needed to evaluate the reasonableness of the TxCRCP ME. For the spalling issue, extensive field evaluations were conducted for the performance of spalling. A spalling model was developed and calibrated with field evaluation data.

Available in PDF, EPUB and Kindle. Book excerpt: As AASH is expected to eventually adopt the MEPDG at its primary pavement design method, it is critical that the SDDOT become familiar with the MEPGD documentation and associated design software. The research conducted under this project was a first step toward achieving this goal.

Download or read book Prestressed Concrete Pavements written by National Research Council (U.S.). Highway Research Board. Committee on Rigid Pavement Design and published by . This book was released on 1963 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design investigations and limited testing of model and prototype slabs indicate that prestressed pavements permit a more efficient use of construction materials in terms of required pavement thickness. Prestressed pavements can be designed with fewer joints and with less probability of cracking than conventional rigid pavements, thereby promising extended pavement life and reduced maintenance requirements. Information relative to the design and construction of prestressed concrete pavements is presented. Recommendations are developed on planning, design, and areas of engineering investigation and research. Minimum tests are recommended for experimental highway pavements. Design variables are discussed with factors affecting design.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mechanistic-empirical (ME) pavement design procedure allows for analyzing and selecting pavement structures based on predicted distress progression resulting from stresses and strains within the pavement over its design life. The Virginia Department of Transportation (VDOT) has been working toward implementing ME design by characterizing traffic and materials inputs, training with the models and design software, and analyzing current pavement designs in AASHTOware Pavement ME Design software. This study compared the measured performance of asphalt and continuously reinforced concrete pavements (CRCP) from VDOTs Pavement Management System (PMS) records to the predicted performance in AASHTOware Pavement ME Design. Model coefficients in the software were adjusted to match the predicted asphalt pavement permanent deformation, asphalt bottom-up fatigue cracking, and CRCP punchout outputs to the measured values from PMS records. Values for reliability, design life inputs, and distress limits were identified as a starting point for VDOT to consider when using AASHTOware Pavement ME Design through consideration of national guidelines, existing VDOT standards, PMS rating formulas, typical pavement performance at time of overlay, and the data used for local calibration. The model calibration coefficients and design requirement values recommended in this study can be used by VDOT with AASHTOware Pavement ME Design as a starting point to implement the software for design, which should allow for more optimized pavement structures and improve the long-term performance of pavements in Virginia.
