RISEffects of Design and Site Factors on Roughness Development in Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper presents the relative influence of design and site factors on roughness development of in-service flexible pavements. The data from the specific pavement study (SPS)-1 experiment of the long-term pavement ...
Relating Axle Load Spectra to Truck Gross Vehicle Weights and Volumes
Publisher: American Society of Civil Engineers
Abstract: Axle load spectra have been used to develop the mechanistic-empirical pavement design guide (M-E PDG). Use of these load spectra provides a more direct and rational approach for the analysis and design of pavement structures ...
Estimating Optimum Timings for Treatments on Flexible Pavements with Surface Rutting
Publisher: American Society of Civil Engineers
Abstract: The evaluation of the pavement preservation interventions is the most important component of a pavement management system. There is a need for a rational methodology to evaluate pavement preservation alternatives to maximize ...
Impact of Local Calibration on Pavement Design in Michigan
Publisher: American Society of Civil Engineers
Abstract: The global Pavement-mechanistic-empirical (ME) transfer functions have been calibrated using the long-term pavement performance (LTPP) pavement sections at the national level. These functions may need calibration for local ...
Use of the Long-Term Pavement Performance Database in the Pavement Engineering Curriculum
Publisher: American Society of Civil Engineers
Abstract: In this paper the writers demonstrate the inclusion of the Long-Term Pavement Performance (LTPP-
Impact of Systematic Axle Load Measurement Error on Pavement Design Using Mechanistic-Empirical Pavement Design Guide
Publisher: American Society of Civil Engineers
Abstract: In traffic characterization, axle load spectra (ALS) are one of the most critical inputs in the new Mechanistic-Empirical Pavement Design Guide (MEPDG). Axle load spectra have a significant effect on predicted pavement ...
Closed-Form Solutions for Bimodal Axle Load Spectra and Relative Pavement Damage Estimation
Publisher: American Society of Civil Engineers
Abstract: The mechanistic-empirical (ME) design procedures utilize axle load spectra to characterize the individual traffic loadings for a site. These loading characteristics are employed to calculate pavement response and for ...
Local Recalibration of JPCP Performance Models and Pavement-ME Implementation Challenges in Michigan
Publisher: ASCE
Abstract: The AASHTOWare Pavement Mechanistic-Empirical (ME) Design version 2.0 performance models were locally calibrated in 2014. Subsequently, the software was updated to versions 2.2 (2015) and 2.3 (2016) since the last calibration ...
Impact of Climatic Data Sources on Pavement Performance Prediction in Michigan
Publisher: ASCE
Abstract: Detailed climatic data are essential for analyzing and designing pavements using AASHTOWare pavement mechanistic-empirical design (PMED). Hourly climatic data are used in the enhanced integrated climatic model in the PMED ...
Effect of Design and Site Factors on the Long-Term Performance of Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: Results are presented from a study to evaluate the relative influence of design and site factors on the performance of in-service flexible pavements. The data are from the SPS-1 experiment of the Long-Term Pavement Performance ...
