rock salt testing

Sandberg can undertake the testing of Salt for spreading on highways for winter maintenance  using the methods given in British Standard BS 3247:2011 incorporating Corrigendum No.1. Sandberg hold a UKAS accreditation to undertake the salt analysis.

About Rock Salt

Every winter, following a snow episode, our roads and highways need to be quickly cleared to allow people to carry on with their normal daily activities.  This is most easily achieved by a combination of physically removing the snow with snow ploughs etc, and/or spreading salt onto the highways.  Additionally with the aid of modern long term weather forecasts, those charged with keeping the roads clear can deploy the salt  in advance of any periods of freezing weather or snow fall.  Salt is at its most effective when it is applied before a freezing episode because it can prevent snow or ice from hard packing.

There are three main types of salt used for winter road maintenance:

Rock Salt - derived by mining natural salt beds

Vacuum salt - salt prepared by the evaporation under vacuum of brine

Marine salt - derived by solar evaporation of sea water

All types of salt work by depressing the freezing point of water.  The particle size distribution of the salt is also an important factor as this will govern the spread of the salt from the height of the salt distribution.  If the salt particles are too fine the with spreading machines conforming to BS 1622 with a height distribution of 300-350mm above the surface of the road the particle velocity may not be sufficient to give a wide spread on one pass. Similarly with particles that are too large they may be spread too widely and end up on the verge of the road.

All salt for spreading on highways for winter maintenance is covered by the British Standard BS 3247:2011 incorporating Corrigendum No.1.
