SURFACE DRESSING WITH K1-70 BITUMEN

As the most cost-effective maintenance processes available to the highway engineer surface-dressing appears to offer considerable growth potential and will play an increasingly important role in the future - both short and long term. The expansion in the use of bitumen road emulsion, particularly of the hot or "warm" applied k1-70 variety, is one of the major success stories in the bitumen road emulsion industry. Since its introduction in the early 1960's the use of K1-70 has now reached a point where over 30 per cent (approximately 70000 tonnes) has been sprayed up to 1980. Since all the surface dressing work done in the UK is carried out with emulsion there is every reason to believe, taking into account environmental, and particularly energy conservation considerations, that a steady increase in market share can be expected. The purpose of this article is an attempt to explain in a little more detail the mechanism of emulsions in respect of surface dressing and possibly the phenomenal rise in their usage. (Author/TRRL)
