Abstract:BAM Wegen constructed the first LEAB (in Dutch: Laag Energie AsfaltBeton; in English: Low Energy Asphalt Concrete) test sections in 2003 Compared to conventional hot produced asphalt mixes, the production temperature of LEAB reduced significantly using foamed bitumen. At first the LEAB concept was applied for asphalt concrete bind and base mixtures (AC bind and AC base mixtures). More recently also test sections with Porous Asphalt (PA) have been built with foamed bitumen. The mixture is called LEAB-PA. The sl… Show more
