Asphalt contg. particles of bitumen and filler - to produce a free flowing powder easy to handle and transport

摘要

A freely flowing asphalt consists of granular particles of inter-penetrating quantities of bitumen and filler material. Their mutual proportion can vary in a 7-93% interval. This product has a great chemical stability, can thus be easily handled and stored and can be produced by pulverising bitumen at 100-200 degrees C onto strongly agitated filler.
