This document specifies a method to measure the spreadability characteristics of bituminous mixtures which are able to vary with time. It can be used for the determination of the delay between manufacturing and laying. It is intended to be assistance for bituminous mixtures design rather than a type test.

This document applies to bituminous mixtures both those made up in laboratory and those resulting from work site sampling, with an upper aggregate size not larger than 31,5 mm. It is not applicable to mastic asphalt.
