What is BS 10947 - Spray injection patching for highways and other paved areas about?
BS 10947 is a British Standard that discusses spray injection patching for highways and other paved areas.
BS 10947 specifies performance requirements and gives control procedures for spray injection patching. Spray injection patching is suitable for use on local roads and the strategic network.
Note: Spray injection patching is a product for undertaking permanent and temporary repairs to potholes, small-scale pavement repairs and pre-patching for surface dressing and slurrysurfacing. It can also be used for localized preventative maintenance.

Why should you use BS 10947 - Spray injection patching for highways and other paved areas?
Spray injection patching is a product produced by the process of injecting a mix of graded aggregates and cationic emulsion binder into a shallow surface defect.
BS 10947 specifies quality plan, mixture requirements, quality assurance systematic monitoring and evaluation of the various aspects of an innovative patching operation to maximize probability that minimum standard of quality are being attained by the production process and to achieve the desired level of in-service performance.
BS 10947 also provides guidance on assessment of cohesion, workability and binder drainage by the snowball test.
BS 10947 provides local authorities with a way of specifying a pothole repair process and helps them identify the best repairers. This can introduce greater choice in the market, reduce costs and increase quality. Most importantly, because the process is fast it can increase repair frequency, so potholed roads can be treated quicker and roads will be safer for all users in the longer term.
