About the event

Clause 950 of the Specification for Highway Works specifies requirements for Surface Preservation Systems. They are proprietary liquid coatings and their use is for extending the life of existing asphalt surfacing, ideally as part of a preventative maintenance programme. However, there are various types of treatment with different functions and recent studies provide a basis for developing new requirements and offer an effective asset management strategy on using them on our roads.

Why you should attend

This event will examine;

• The case for the greater use of surface preservation systems in a planned road maintenance programme
• Dr Chibuzor Ojum describes the different types of system and considers the relative benefits, with recommendations from the findings of the studies
• Sunni Samra gives advice about the use and performance of one type of asphalt preservation system.
