Salt movement and accumulation within roads

摘要

A paper given at the 2011 RTA NSW Pavements Conference explores the mechanisms of road pavement salinisation with a focus on roads within areas at risk of environmental salinity, primarily dryland salinity. It reports a RTA-University of Newcastle project consisting of a number of components including; construction and monitoring of field-scale test pavement, a long-term laboratory column study, investigation of existing salt-affected roads and modelling of salt movement and accumulation within road pavements. Some preliminary results are also presented.
