Landslide Monitoring and Modelling
Landslides can cause potentially costly damage and disruption to Scottish road infrastructure. Debris-flows, a fast-moving torrent of solids mixed with water, are by far the most frequent cause and are capable of wide-reaching impacts, due to their high mobility. Many debris flow events have been recorded across Scotland, particularly at the highly active A83 Rest and be Thankful (RabT). This report builds on previous work on debris flows in Scotland. It demonstrates the potential of Terrestrial Laser Scanning and modelling to enable a better understanding of the hazards, particularly runout. A key finding of the monitoring has been the segregation of slope failure processes into either the modification of existing hillslope gully systems (producing net deposition or scour), or the development of new channels or channel regions. Both effects are significant, as they may result in the release of otherwise consolidated/poorly consolidated sediment stores.
Renewable Energy Generation and Distribution from Road Network Assets

Study to consider how new surfacing materials are performing in service on the network, with outputs used to compare with Polished Stone Value (PSV) and inform improvements in skidding performance and value for money in terms of imported aggregate.
High Speed Friction Testing
Study to carry out high-speed friction testing on a range of road surfacing used on the Scottish trunk road network. A Pavement Friction Tester (PFT) will be used to collect important data on wet skid resistance. The overall aim of this research is to optimise the durability, sustainability and safety of surface courses used on the Scottish trunk road network.
The Value of the Trunk Road Network to Society and Economy in Scotland
Research to estimate the contribution of the motorway and trunk road network to the society and economy, and how to quantify the benefits of investment in maintaining the network. The research will demonstrate how this investment contributes towards the Scottish Government purpose of providing opportunities for all of Scotland to flourish, through increasing sustainable economic growth. The outcomes from the project will inform the case for continuing investment in the motorway and trunk road network in the upcoming Spending Review
Road Marking Durability & Adhesion to TS2010
Second phase of earlier study to investigate issues experienced by the road marking industry in applying signing and lining markings to TS2010 surfacing. The study will involve a literature review followed by network trials and development of a draft code of practice.
