Recycled asphalt production
WebRecycled asphalt pavement (RAP) shows promise at reducing natural resource consumption and construction energy requirements. While reducing heat and increasing use of recycled asphalt are obvious tech- niques to make asphalt pavement more sustainable, the quantification of their benefits and impact on service life are unknown. WebWhile conventional asphalt is produced at around 170°C, the low temperature processes of today allow production temperatures of around 100°C. Lowering the manufacturing temperature eases energy needs, and therefore emissions, too. LTA impacts the entire production process – including drying, mixing sequences and recycling.
