This Standard sets out the method for determining the lime or cement content of pavement materials mixed with lime or cement which are sampled from a project under construction and tested within a limited period after the completion of mixing.

This Standard sets out the method for determining the lime or cement content of pavement materials mixed with lime or cement which are sampled from a project under construction and tested within a limited period after the completion of mixing.The method applies to crushed rock materials. (See Note.)NOTE: Inaccurate results may be obtained with calcareous materials, e.g. calcrete. This may be checked by examining the response of the unstabilized materials to the test procedure.
