Influence of unbound material properties on rutting potential of low volume roads

摘要: A B ST R C T More than 80% of roadway mileage in the world carries less 400 vehicles per day and these roads are classified as low volume roads. India has essentially a rural oriented economy with 72% its population living villages. The part tertiary road system, which consists other district village traffic conditions on distinctly different from major variety used for transportation goods roads, ranging bullock-carts to fast moving commercial vehicles. Permanent deformation unbound base sub-base layer is one distress types that require extensive maintenance. gradation most important property an aggregate can contribute performance pavement. In present study, attempt been made investigate rutting potential taking into account course gradation, field density, subgrade moisture content, California Bearing Ratio, volume. influence factors in-service pavements investigated response type model developed.
