Managing the Impacts of Rising Watertables and Salinity on Remaining Pavement Life: Report of 2005/2006 Activities
This report comprises a technical review and update on new knowledge about salinity impacts and pavements. A review of recent literature and research outputs has indicated that there are knowledge gaps in the area of how salinity affects pavements…
Investigation of the Load Damage Exponent of Unbound Granular Materials Under Accelerated Loading
This report details the experimental program, analysis and findings of the assessment of the impacts of axle mass increases on road deterioration for sprayed seal surfaced unbound granular pavements. Load-damage exponents ranged between two and four…
Improved Distress Viscosity Model for Reseal Intervention
An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…
Development of an Aggregate Size Term for a Reseal Intervention Model
An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…
