Long-Term Modelling of Composite Pavement Performance
The rehabilitation of rigid (concrete) pavements with the placement of an asphalt overlay is a common maintenance technique, which results in a structure known as a composite pavement. The most common form of distress in this type of pavement is reflection cracking which can be due to traffic …

Effects of basecourse saturation on flexible pavement performance.
… to the premature failure of flexible asphalt pavements. Basecourse saturation results in increased flexural strains in the asphaltic layer and increased rutting leading to cracking of the surface layer. To obtain a physical and quantitative understanding of the deformation characteristics of …

Validating the empirical distress prediction models within the AASHTOWare Pavement Mechanistic-Empirical Design, using Tennessee pavement performance data from the Long Term Pavement Performance database
The Mechanistic-Empirical Pavement Design Guide (MEPDG) represents a recent pavement design approach, developed to address the shortcomings of the 1993 AASHTO Guide for Design of Pavement Structures. The Pavement Mechanistic-Empirical Design (PMED) software is set to operationalize the …

Development of Pavement Performance Evaluation Subroutines for 3D-Move Analysis Software
Predicting the pavement performance of existing and new asphalt concrete (AC) pavements is an important and significant task of pavement engineers. It is important to quantifying the factors (material properties, environmental factors and traffic loading) that lead to the pavement deterioration. …

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 …

Low volume Portland cement concrete pavement performance evaluation and rehabilitation strategy selection
… of all 43 existing portland cement concrete pavements in Boone County, Iowa. The research was directed at the evaluation of the factors effecting the performance the county pavements. Equations relating the design parameters to the commonly identified concrete distresses in pavements are also …

Targeting aggregate marginality from a chemical and materials perspective to improve pavement performance
… comparatively lower cost in comparison to bound pavement layers, are extensively used in the construction of road pavements. Thus, it is not surprising that a careful testing and selection of these materials is required to ensure a longlasting pavement life that avoids early and costly …

Evaluation of In-Situ variability of concrete pavement characteristics and their effect on performance
Pavement performance prediction must account for uncertainties in pavement characteristics, climate, traffic loading, etc. Past research identified that concrete thickness and flexural strength were two pavement characteristics that significantly affected transverse cracking in Jointed Plain …

Asphalt Perpetual Pavement Design: Utilizing Existing Pavement Systems in Ohio
This thesis explores asphalt perpetual pavement concepts by investigating existing asphalt concrete (AC) pavements in Ohio. In 2010, twenty AC pavement sites were selected as candidates for a forensic investigation in Ohio. Field distress surveys, coring, Falling Weight Deflectometer (FWD), Seismic …

Comparison of LTPP-Bind V3.1 and MEPDG for the Selection of Binder Grades
Binders for five analysis locations and two pavement designs were selected using the LTPPBind V3.1 software. The recommended binders were then refined to meet realistic constraints of pavement construction in West Virginia. The performance of pavements with the selected binders, pavement structures …

Pedologic Based Subgrade Characterization for Low-Volume Pavement Design
Subgrade soils play an integral part in pavement performance. The nature and properties of subgrade soils must be considered in structural pavement design. Many highway agencies, particularly agencies that administer "local" or low-volume pavements, do not have the resources to conduct …

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) …
