Abstract: Infrastructure management decisions, such as condition assessment, performance prediction, needs analysis, prioritization, and optimization are often based on data that is uncertain, ambiguous, and incomplete and incorporate ...

Abstract: Pavement preservation programming often involves multiple objective considerations. Traditional single-objective optimization frameworks consider one single objective while imposing competing objectives as constraints in ...

Abstract: An experimental study was conducted to characterize the dynamic mechanical properties of elastomer-modified asphalt binders at intermediate and high temperatures. Two types of elastomeric modifiers, styrene-butadiene-styrene ...

Abstract: Measurement of pavement macrotexture by noncontacting means is often contaminated by erroneous readings made by the instrument. These errors can be caused by extreme diffusion or refraction of the light source by aggregate ...

Abstract: This paper investigates the possibility of using pavement deflection measurements obtained from a traffic speed deflectometer (TSD) for network-level structural evaluation on bituminous pavements in Virginia. Virginia ...

Abstract: This paper discusses the results of the field experimentation of a new system developed to help inspect the construction of asphalt pavements using digital video images. The system computes the gray-level co-occurrence ...

Abstract: This paper shows that the pavement structural condition as measured by the traffic speed deflectometer (TSD) has an impact on the rate of deterioration of the surface condition on a 6,469-km (4,020-mi) subset of the Virginia ...
