BS EN 13286-1:2021 PDF Download

BS EN 13286-1 is a part of a series of documents that is applicable to unbound and hydraulically bound mixtures. It specifies test methods for determining the relationship between water content and density of these mixtures under specified test conditions. The test results serve as an estimate of the achievable mixture density and provide a reference parameter for evaluating the density of the compacted layer. These results are used as a basis for specifying requirements for hydraulically bound and unbound mixtures, and also help in determining the water content required for satisfactory compaction.

This standard is relevant for manufacturers and suppliers of unbound and hydraulically bound mixtures, suppliers of binders, equipment suppliers, civil engineers, contractors, and highway and road transport authorities. It is especially important for those involved in pavement sub-base construction, where hydraulically bound mixtures are commonly used.

The use of BS EN 13286-1 helps ensure the quality and performance of hydraulically bound mixtures, reducing material production costs by eliminating quarrying, crushing, and screening operations. It also facilitates faster compaction times, potentially reducing congestion for road users. The updated version of the standard, BS EN 13286-1:2021, includes editorial revisions and a change to the particle size range in one of the test methods.
