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…

Selection of maintenance techniques is always a balance between the administering authority costs and social and environmental costs and outcomes. This project provides practical information and a methodology (including a worked example) for…

This Report examines the role of noise impact assessment in the management of road traffic noise. Part 1 provides an overview of noise impact assessment including issues such as the existing noise environment, route selection and route changes,…

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…

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).…
