The Effect of Pavement Temperature on Frictional Properties of Pavement Surfaces at the Virginia Smart Road
Wet-pavement friction is a public concern because of its direct relation to highway safety. Both short- and long-term seasonal variations have been observed in friction measurements. These variations have been attributed to different factors, such as traffic, rainfall, and temperature. Since both …

Analytical solutions for temperature profile prediction in multi-layered pavement systems
Accurate prediction of pavement temperature profile is essential to better characterize the mechanistic properties of paving materials and predict pavement responses under traffic and environmental loadings. In practice, characterizing the field temperature profiles are desired in order to …

Mechanistic Analysis of in-Service Airfield Concrete Pavement Responses
The effect of temperature curling on pavement responses was analyzed. A theoretical analysis of the effect of pavement temperature distribution on total and load-induced responses is presented and complemented with Analysis of Variance (ANOVA). The analysis of in-situ interface condition was based …

Moisture Content Determination and Temperature Profile Modeling of Flexible Pavement Structures
… a granular base material. The strength of this pavement system is strongly influenced by the local environmental conditions. Excessive moisture in a granular base layer can cause that layer to lose its structural contribution by reducing the area over which loading may be distributed. Excessive …

Development of a Mechanistic-Based Approach to Evaluate Critical Conditions of Hot Mix Asphalt Mixtures
The performance of an asphalt pavement is significantly impacted by the properties of the asphalt mixture, pavement structure, and the imposed environmental and traffic loading conditions. In particular, hot mix asphalt (HMA) mixtures are believed to have a critical combination of temperature and …

The evaluation and modification of a prediction model for road surface temperatures
One version of a Surface Temperature Prediction Model has been evaluated and modified to precisely predict road temperatures and road conditions during winter nights under all weather conditions at rural, suburban, and urban sites. The Partial Differential Equation approach gives encouraging …

The Effect of Tree Shade and Snowpack Cover on Pavement Surface Temperature
… of tree shade on the surface and internal temperature of pavement structures can be significant throughout the year. While much work has been done in researching the influence of tree cover on localized urban heating during hot summer months, less effort has been put towards the research of …

Uncertainty quantification for pavement life-cycle stages
… rolling resistance (RR), a major component of pavement LCA use stage, has significant impact on transportation-related energy consumption. Pavement related RR mainly includes pavement structure, surface roughness (or smoothness) and texture. This research aims at addressing current challenges …

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 …

Development and validation of a novel testing procedure for the evaluation of rutting susceptibility of bituminous binders.
… resistance of asphalt mixtures used in road pavements. In the first phase of research four different types of asphalt binders were analyzed by subjecting them to a new protocol combining Single Creep-Recovery (SCR) tests with Multiple Stress Creep (MSC) tests on DSR. Low shear viscosity (LSV) …

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 …
