The Association of Road Surface Dressing Contractors was formed in July 1942 and became the Road Surface Dressing Association in October 1962. There were substantial improvements in equipment and technique progressing from horse-drawn tankers and hand chipping to lorry mounted pressure sprayers and self-propelled chipping machines.
Surface dressing, also known as chipseal bituminous surface treatment, or seal coat, is a surface treatment comprised of an application of bitumen – in the form of emulsion, hot binder or cutback – to a pavement surface quickly followed by a layer of aggregate chippings. After application, the seal may be rolled to
Where a binder is to be applied on a granular surface, the surface shall be free of standing water and shall be prepared by dampening, fine grading, and compacting immediately prior to the application of the binder. The surface shall be finish rolled to ensure a compacted smooth and float free surface. 304.07.05 Binder Application Temperatures

What is surface dressing? Surface dressings can be applied to roads in order to preserve and seal the surface in one application. This work can be done by hand; however, it is not uncommon for larger applications to be done via spray tanker. Surface dressing also has many other benefits. For example, it offers the road permanent waterproofing.
