DD CEN/TS 15324 on bitumen and bituminous binders is useful for:

it should be undertaken with care and should only be done when users are satisfied that it will not result in a lower level of reliability than the minimum level set in the first generation Eurocodes and associated UK National Annexes

The method is suitable for other bituminous binders than paving grade bitumen

It also depends on the depth of embedment of the load – the deeper it is founded
