National Highways is responsible for the operation of the strategic road network in England, comprised of motorways and major trunk roads.

On this network, there are nearly 50,000 geotechnical assets formed in, or from, the wide variety of geological materials that exist around the country. Whilst relatively young, and rarely undergoing significant failures, these assets do show signs of defects and deterioration.  The potential impact of this deterioration could increase in time if it is not understood and managed.

To this end, Mott MacDonald, in collaboration with Coffey Geotechnics and Winter Associates, have undertaken a task to model the deterioration of the assets.

This assessment has been undertaken based on analysis of nearly 20 years of inspection data for the assets, held in the Geotechnical and Drainage Management Service (GDMS).

This presentation will describe the work undertaken and the conclusions reached.  As part of the analysis, the potential impact of future climate change was modelled, using outputs from the ACHILLES research programme and expert judgement.

Tea and coffee from 17:45.

Dr Chris Power

Dr Chris Power (Chartered Geologist, BSc in Geology, PhD in rock mechanics) is a Technical Director in the Civils Asset Management group of Mott MacDonald.

After starting his career as an engineering geologist, he became involved in the developing practice of geotechnical asset management in the early 2000s and has worked in the area ever since.

Chris has helped UK transportation owners develop their geotechnical asset management policies, strategies and procedures over many years, and has a long involvement with the Geotechnical and Drainage Management Service of National Highways (previously known as HAGDMS).

He has also worked extensively with Network Rail to help them develop and improve their asset management procedures for earthworks.  He is a strong advocate for providing industry support to University research projects, and has supported many MSc dissertations at the University of Leeds and is the current chair of the Industry Advisory Group for the ACHILLES research programme.
