Abstract

The analysis of data from a kilometre of surface dressing which was laid in 1988 on the A413 at Amersham, Buckinghamshire, to provide a test site of varying micro-texture and macro-texture. This trial site provided a wide range of aggregate sources and sizes, all applied with the same binder on to a rolled asphalt substrate, part of which was left exposed as a control section. The macro-texture performance of this site has been closely monitored and the considerable quantity of data accumulated has been analysed to investigate possible relationships between surface dressing performance, aggregate properties, and the original design.
