Het toepassen van lichtgewichttoeslagstoffen in asfaltbetonspeciën ter bevordering van de levensduur en stroefheid van top- en deklagen in asfaltbeton.

Since 15 years experience has been gained with asphaltic concrete mixtures for wearing courses of highways in which part of the course aggregate has been replaced by electrodes slag whereas the sand fraction is composed of natural sand, crushing sand and a special clinker. A better durability and a lasting skidding resistance can be achieved in this way.
