BS EN 1097-8 is the eighth part of the BS EN 1097 series of documents that describes the reference method used for type testing and in case of dispute for determining the polished stone value (PSV) of a coarse aggregate used in road surfacings.
For other purposes, in particular factory production control, other methods are possible provided that an appropriate working relationship with the reference method has been established.
BS EN 1097‑8 on the determination of the resistance of aggregates is useful for:
Polished stone value (PSV) is a measure of the resistance of a coarse aggregate to the polishing action of vehicle tyres under conditions that simulate those occurring on the surface of a road.
BS EN 1097‑8 provides test methods to determine the polished stone value (PSV) of a coarse aggregate used in road surfacings providing detailed requirements for the control of materials. Also, provides information on the equipment used for the preparation of test specimens.
Overall, these test methods give the mean value for the PSV control stone to provide a comparison against which the results of the aggregate under test can be measured. Furthermore, BS EN 1097‑8 helps you with the measurement of the polished stone value (PSV) of a material used as road surfacing to provide a polished surface under the action of vehicle tyres.
