Sufficient aggregate needs to be stockpiled in the vicinity of the job. If the aggregate has been stockpiled for a long period it may need to be screened to remove contaminants. Aggregate should be separated into lots at the stockpile site, so that application rates can be adjusted to cater for variations in ALD.

Precoating is advisable and this may be done at the quarry or a plant, which is the most efficient method. However, precoating can also be done in the field. Both screening and precoating can be carried out in a single operation at the stockpile site.
