Improving the cost effectiveness of asphalt surfaced gravel roads

This project will update the guidance and design methods for thin asphalt surfaced gravel roads, used by jurisdictions to cost effectively manage their road networks. The project will strengthen the relationships between the real-world performance and the laboratory performance of pavement materials. Improved laboratory and field performance correlations should lead to cost savings and better risk management. The work is also expected to facilitate the assessment and introduction of innovative pavement solutions.

Improved guidance about thin asphalt surfaced pavements should see a reduction in the proportion of thin asphalt surfaced pavements failing earlier than expected (due to selection or design issues).
