Bibliography

This document specifies a test method for determining the suitability of aggregates and cationic emulsions for slurry surfacings and, where appropriate, the effect of individual additives.This document applies to slurry surfacings.NOTE 1The procedure uses a standard mixture but the method may also be used to assess the effect of variations in the grading and binder content but this use is not part of the standard.NOTE 2Additives affecting the breaking behaviour may also be tested under standardised conditions. The test may also be used to study the effect of a particular type of bitumen or emulsifier.
