GoToWebinar: This webinar, organised by CIHT East Midlands, will look at road foundations and the effect of having a functioning drain, with the aim to understand what should be the ideal pavement structural build-up (from a drainage point of view).
After a brief look at surface skidding/aquaplaning issues, our speaker, Nick Thom, will be introducing a method for working out just how wet it is in a road foundation, how that fluctuates through a typical year, the likely impact on rate of deterioration, and the effect of having a functioning drain.
The key factors that will be considered are:
The permeability of asphalt – cracked or not; the type (and permeability) of subbase and capping materials, the type of soil, and the crossfall.
This will lead to thoughts about the ideal pavement structural build-up from a drainage point of view.
Anyone concerned with road (or airfield pavement) life / design / construction / management. It should be of interest to all job levels, i.e. those dealing with the engineering detail and those dealing with things like budget management but particularly to anyone who might be a sub-surface drainage specialist.
Nick Thom, Assistant Professor at University of Nottingham
Nick has been involved in pavement engineering for nearly 40 years, in consultancy and then academia, including research.
Research topics have included non-standard materials, geogrids, SAMIs, and he is now focusing attention on surface deterioration (ravelling and potholes).
His motivation, both in practice and research, has been to predict performance as reliably as possible using relatively simple scientific principles, and the technique introduced in this webinar represents a recent advance in this area.
