PD 6689:2017 PDF Download

PD 6689:2017 is a published document that provides guidance on the use of two European standards, BS EN 12271 and BS EN 12273, related to surface treatments for road surfaces. The document is primarily aimed at public bodies, specifiers, designers, contractors, material suppliers, consultants, test houses, and highway authorities involved in specifying or delivering road surfaces or other trafficked areas in the UK.

The purpose of PD 6689:2017 is to ensure that road surface dressing and slurry surfacing products meet the necessary performance requirements and installation control procedures. It helps to choose products that are suitable for environmental conditions and optimize durability, safety, and efficiency. The document also helps prevent over-specification and minimizes the use of scarce resources. It provides guidance on specifying the level of end-performance required for different road classes, as the BS EN standards only define performance categories without indicating specific performance levels.

The updated version of PD 6689:2017 includes sections on surface dressing and slurry surfacing, updated information on CPR, Declaration of Performance, and CE marking. It also updates tables, performance categories, and sections on binders and chippings for surface dressing. The installation section has new guidance on tolerance and accuracy, while the sections on materials, design, and factory production control for slurry surfacings have been updated. The document also includes new information sheets and updated example specifications in the annexes.
