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 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 ...
