Samenvatting
This paper details a quantitative evaluation of six commercially available chemical stabilising agents on a section of unsealed road in the far north of South Australia. Trial sections of unsealed road monitored over a three year period are reported. Evaluations included measurement of pavement stiffness, roughness, loose surface material and rutting. A concurrent rating survey of road user perceptions of surface conditions was undertaken during the full assessment period to link with quantitative assessments. Life cycle models were developed for estimating the rate of wear of sheeting and subsequent life cycle costing for three maintenance strategies evaluated for each product. (a)
