Abstract: The Highway Economic Requirements System (HERS) is an analysis tool that was developed with the primary purpose of estimating the future investment requirements of the US road network, which directly informs the biennial ...

Abstract: The structural capacity of a pavement has been shown to be an excellent indicator of the required maintenance and expected performance of asphalt pavements, but studies reported in the literature have produced few indices ...

Abstract: In this paper, the difference sequence method is used to decompose traffic speed deflectometer (TSD) deflection slope measurements variability into “true” spatial variability that is due to pavement structural changes and ...

Abstract: This paper presents a network-level structural capacity indicator for asphalt pavements in the state of Virginia. A literature review revealed that several network-level structural capacity indexes have been proposed, and ...
