Method of providing a surface dressing for a roadway |
摘要 |
The invention relates to a method of providing a surface dressing for a roadway and includes contacting an aggregate (granular material) and a binder in situ on the roadway and heating the layer thus formed to a temperature measured at about 1mm. below the surface of the layer of betweeen 100 DEG C and 200 DEG C. The method can be applied either to a new surface dressing or to a repair operation and in the latter instance where the surface has become polished as a result of loss of aggregate from the surface, the aggregate is merely distributed over the polished surface and the heat applied to the required temperature.
