Mechanistic-Empirical Evaluation of Pavement Damage and Cost Attributed to Overweight Single-Trip and Multi-Trip Scenarios in Nevada
… resources tomaintain the conditions of roadway pavements at an acceptable level.This dissertation presents an approach that allows the estimation of pavementdamage associated costs (PDAC) attributable to OW vehicle moves. The PDAC can beestimated for different OW axle loadings and configurations …

Effect of Varying Amounts of Sandstone on the Performance of Asphalt Mixtures in Arkansas
… can lead to performance issues and premature pavement damage. It has been suspected in Arkansas that an excessive amount of sandstone in asphalt mixtures may be a culprit of some of these premature pavement damage issues, especially regarding the moisture susceptibility of a pavement. This …

Quantification of the effects of heavy agricultural vehicle loading on pavement performance.
… Minnesota. There were both flexible and rigid pavement sections implemented with strain gauges, LVDTs and earth pressure cells at the MnROAD testing facility. The objective of this study was to investigate the effects of farm equipment on the structural responses (stresses and strains) of …

Reinforcement of pavement subgrade using granular fill and a geosynthetic layer
Engineers are often faced with construction of pavement structures over soft and compressible subgrade. Such conditions render the structures unable to withstand required design loads and thus are susceptible to high settlements associated with excessive distress leading to pavement damage. The use …

Multiclass Origin-Destination Estimation Using Multiple Data Types
… due to different emission characteristics, pavement damage, etc of trucks. This thesis proposes a bilevel optimization model and corresponding solution method for static multi-class O-D estimation using various types of data. Limited memory BFGS method with bounded constraints is used for …

Dynamic analysis of a modern urban bus for assessment of ride quality and dynamic wheel loads
… known to cause poor ride quality and excessive pavement loads. Such performance is partly due to the present status of urban roads and their rapid deterioration. On the other hand, variations in the dynamic tire forces of such vehicles are known to be a cause for acceleration of road damage and …

Influence of road roughness and directional maneuvers on the dynamic performance of heavy vehicles
… directional performance measures and the road damage potentials of the vehicle undergoing a directional maneuver. The directional performance characteristics and the road damage potentials are investigated for low speed cornering and high-speed directional maneuvers. A number of measured road …

Flexible Pavement Dynamic Response Analysis and Validation for Various Tire Configurations
Flexible pavement responses to vehicular loading such as critical stresses and strains, in each pavement layer, could be predicted by the multilayered elastic analysis. However, most of conventional approaches suffer from major drawbacks including material properties considered in the analysis, and …

Adjustment factors for MEPDG pavement responses considering three- dimensional analysis and wide-base tire
The Mechanistic-Empirical Pavement Design Guide (MEPDG) provides a superior methodology as compared to its predecessor in the design and analysis of pavement structures. The mechanistic (MEDPG analysis) calculates critical pavement responses due to pavement-tire interactions. On the other hand, the …

Analysis of tire-pavement interaction and pavement responses using a decoupled modeling approach
The proper understanding of tire-pavement interaction is important for the accurate analysis of load-induced stresses and strains in the pavement structure. This dissertation focuses on the analysis of the mechanism of tire-pavement interaction and the effect of tire-pavement interaction on …

Influence of tire-pavement thermomechanical interaction on contact stresses and rolling resistance
… infrastructure investments. Considering a loaded-pavement scenario, the behavior of flexible or asphalt-concrete-surfaced pavements is significantly influenced by both loading and environmental conditions. Heavy truck loads govern pavement responses and, thus, the eventual pavement damage. The …

Development of mechanistic rolling resistance model for pavement life cycle assessment
… It has been shown that a major component of pavement LCA results from rolling resistance (RR) between vehicle-pavement interaction. This study focuses primarily on the development of mechanistic RR model to capture the impact of excess fuel consumption (EFC) and dynamic wheel load (DWL) …

On Cross-Anisotropy of Flexible Pavement Layer Materials for Improved Pavement Responses
<p>Pavement layer materials are typically assumed to be isotropic in determining pavement responses, such as stress and strain. The main benefit of the isotropic assumption is that stiffness defined by modulus of elasticity (E-value) is equal in all directions. In reality, stiffness along vertical …
