WARM-MIX ASPHALT MIXTURE WITH LOW CARBON EMISSION

摘要

PURPOSE: A low-carbon medium-temperature asphalt mixture is provided to reduce the emission of carbon dioxide by lowering 30-50 degrees of construction temperature. CONSTITUTION: A low-carbon medium-temperature asphalt mixture is produced as follows. Aggregate having a 20 or 13mm size 92-96 weight%, straight asphalt 3.8-6 weight%, and middle-temperature reforming agent 0.2-4.0 weight% are put into a mixer and are mixed with 125-145 degrees of temperature. The porosity of a paved road is 3-5%, and the porosity of the aggregate is over 12%.
