FRESH IDEAS SURFACE

The article outlines some of the latest developments in road maintenance techniques and materials. Cooperation between highways authorities, research organisations, and specialist contractors is stimulating valuable developments in road maintenance in the UK. The Highways Agency and County Surveyors Society Network are jointly developing a system for materials approval that extends design to approval for use. One of the most significant recent asphalt surfacing developments has been the introduction of thin surfacing to the range of wearing course materials. The two types of thin surfacing available in the UK are UL-M and Safepave. Other recent wearing course materials include: (1) Stone Mastic Asphalt, a binder-rich mastic designed to fill the void of a coarse aggregate skeleton; (2) micro-surfacing, a thin durable wearing course; and (3) permanent cold-lay surfacing materials for roads and footways. Developments for lower pavement layers include Foamix, a foamed bitumen product, and porous asphalt. Many of these developments rely on polymer-modified bitumens and on development of binders such as Multiphalte. There have also been improved surface dressings, anti-skid materials and materials for concrete and blacktop repair.
