Testing aggregates. Method for determination of frost heave

Status : Current, Confirmed   Published : April 2009



BS 812-124:2009 Testing aggregates. Method for determination of frost heave

Aggregates are the most commonly used construction minerals in the UK. They are widely distributed with a range of potential sources and are used in very large quantities. Testing these minerals is therefore very important.

BS 812-124 describes a test procedure for the determination of the frost resistance of unbound aggregate mixtures. It covers mixtures that have been compacted to form a cylindrical specimen with a predetermined water content and density.

BS 812-124 applies to unbound aggregate mixtures used in the construction of roads and other paved areas at a depth that might experience frost penetration.

BS 812-124 includes an option for the use of comparator specimens to confirm that the test chamber is working correctly.

Who will find BS 812-124 useful?

  • People working with the Highways Agency
  • Consulting Engineers
  • People dealing with quarry products
  • Civil Engineers
  • All those involved with testing materials/minerals.

BS 812-124 replaces BS 812-124:1989 which is now withdrawn.
