Book Synopsis Improved Characterization of Truck Traffic Volumes and Axle Loads for Mechanistic-empirical Pavement Design by : Ala R. Abbas
Download or read book Improved Characterization of Truck Traffic Volumes and Axle Loads for Mechanistic-empirical Pavement Design written by Ala R. Abbas and published by . This book was released on 2012 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recently developed mechanistic-empirical pavement design guide (MEPDG) requires a multitude of traffic inputs to be defined for the design of pavement structures, including the initial two-way annual average daily truck traffic (AADTT), directional and lane distribution factors, vehicle class distribution, monthly adjustment factors, hourly truck distribution factors, traffic growth rate, axle load spectra by truck class (Class 4 to Class 13) and axle type (single, tandem, tridem, and quad), and number of axles per truck. Since it is not always practical to obtain site-specific traffic data, the MEPDG assimilates a hierarchal level concept that allows pavements to be designed using statewide averages and MEPDG default values without compromising the accuracy of the pavement design. In this study, a Visual Basic for Application (VBA) code was developed to analyze continuous traffic monitoring data and generate site-specific and statewide traffic inputs. The traffic monitoring data was collected by 143 permanent traffic monitoring sites (93 automated vehicle classifier (AVC) and 50 weigh-in-motion (WIM) sites) distributed throughout the State of Ohio from 2006 to 2011. The sensitivity of the MEPDG to the various traffic inputs was evaluated using two baseline pavement designs, one for a new flexible pavement and one for a new rigid pavement. Key performance parameters for the flexible pavement included longitudinal (top-down) fatigue cracking, alligator (bottom-up) fatigue cracking, transverse (low-temperature) cracking, rutting, and smoothness (expressed using IRI), while key performance parameters for the rigid pavement included transverse cracking (% slabs cracked), joint faulting, and smoothness. The sensitivity analysis results revealed that flexible pavements are moderately sensitive to AADTT, growth rate, vehicle class distribution, and axle load spectra; and not sensitive to hourly distribution factors, monthly adjustment factors, and number of axles per truck. Furthermore, it was found that rigid pavements are moderately sensitive to AADTT, growth rate, hourly distribution factors, vehicle class distribution, and axle load spectra; and not sensitive to monthly adjustment factors and number of axles per truck. Therefore, it is recommended to estimate the AADTT and the vehicle class distribution from site-specific short-term or continuous counts and obtain the truck growth rate from ODOT Modeling and Forecasting Section (Certified Traffic). As for the other traffic inputs, statewide averages can be used for the hourly distribution factors, axle load spectra, and number of axles per truck; and MEPDG defaults can be used for the monthly adjustment factors.

Book Synopsis Analysis and Determination of Axle Load Spectra and Traffic Input for the Mechanistic-Empirical Pavement Design Guide by : Yi Jiang
Download or read book Analysis and Determination of Axle Load Spectra and Traffic Input for the Mechanistic-Empirical Pavement Design Guide written by Yi Jiang and published by Purdue University Press. This book was released on 2008-03-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The values of equivalent single axle loads (ESAL) have been used to represent the vehicle loads in pavement design. To improve the pavement design procedures, a new method, called the Mechanistic-Empirical Pavement Design Guide (MEPDG), has been developed to use the axle load spectra to represent the vehicle loads in pavement design. These spectra represent the percentage of the total axle applications within each load interval for single, tandem, tridem, and quad axles. Using axle load spectra as the traffic input, the MEPDG method is able to analyze the impacts of varying traffic loads on pavement and provide an optimal pavement structure design. In addition, the new method can be used to analyze the effects of materials and the impacts of seasons, to compare rehabilitation strategies, and to perform forensic analyses of pavement conditions. The MEPDG utilizes mechanistic-empirical approaches to realistically characterize inservice pavements and allows the full integration of vehicular traffic loadings, climatic features, soil characteristics, and paving materials properties into the detailed analysis of pavement structural behaviors and the resulting pavement performance. In order to provide the traffic data input required by the MEPDG, the Indiana Department of Transportation (INDOT) made an effort to obtain truck traffic information from the traffic data collected through weigh-in-motion (WIM) stations. This study was conducted to create the truck traffic spectra and other traffic inputs for INDOT to implement the new pavement design method. Furthermore, the INDOT AADT data were used in this study to analyze the spatial distributions of the traffic volumes in Indiana and to obtain the spatial distributions of traffic volumes.

Book Synopsis Effect of Michigan Multi-axle Trucks on Pavement Distress by :
Download or read book Effect of Michigan Multi-axle Trucks on Pavement Distress written by and published by . This book was released on 2009 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the adoption of the new mechanistic-empirical pavement design method and the employment of axle load spectra, the question of evaluating the pavement damage resulting from different axle and truck configurations has become more relevant. In particular, the state of Michigan is unique in permitting several heavy truck axle configurations that are composed of up to 11 axles, sometimes with as many as 8 axles within one axle group. Thus, there is a need to identify the relative pavement damage resulting from these multiple axle trucks. The study looked at both flexible and rigid pavement systems, and comprised of three main components: (1) inservice pavement performance data; (2) laboratory testing under multiple axles, and (3) mechanistic-empirical analyses. The results from in-service pavement performance data indicated that multiple axle groups appear to cause less damage in fatigue per load carried for both pavement types, whereas they cause more damage in rutting of flexible pavements and roughness for rigid pavements. Laboratory testing of asphalt concrete confirmed that multiple axles cause less fatigue damage per load carried, and that rutting is nearly proportional to the number of axles within an axle group. Results from flexural concrete beam fatigue testing showed significant variability; multiple linear regression analysis (independent variables: stress ratio, stress impulse and initial modulus of elasticity) indicated, on average, similar findings to asphalt concrete fatigue for a given stress ratio; however, mechanistic analysis showed that multiple axles cause considerable stress reduction leading to significantly lower fatigue damage. The mechanistic analysis also showed that multiple axles cause more faulting in rigid pavements. Mechanistic analyses of flexible pavements confirmed that multiple axles cause less fatigue damage per load carried, and rutting damage that is nearly proportional to the number of axles within an axle group. However, the mechanistic-empirical results suggest that the AASHTO Load Equivalency Factors (LEF) for large axle groups may be unconservative. Finally, Full scale slab testing to study joint/crack deterioration in plain concrete pavements was inconclusive.
