MICROSURFACING FOR HEAVILY TRAFFICKED ROADS

In recent years the general increase in community awareness of the need for improved road performance with respect to safety and comfort has resulted in the road asset owner focussing attention on a range of new surfacing options. The primary considerations for the road user are safety and ride, while surfacing durability and cost effectiveness are additional considerations for the owner or operator. The new generation of pavement surfacing and maintenance systems may be broadly described as either very thin or ultra thin and embody the principle of "separation of function" which holds that the user function of a road may be separated from the structural or load bearing function. This principle was formally realised by a French company, Screg Routes, in the late 1980s with the development of the ultra thin "paver laid sprayed seal". Following this development a number of competing processes have evolved. A detailed report on thin bituminous surfacings by Oliver provides a comparison of field performance of some of these systems in relation to properties desirable to the user. The types of surfacings reviewed include paver laid sprayed seal, thin asphalt, fibre reinforced sprayed seals, cold paver laid asphalt and slurry surfacing. This paper is essentially concerned with developments in the slurry surfacing system. (a) For the covering entry of this conference, please see ITRD abstract no. E202467.
