Low-noise asphalt mixture and method for manufacturing the asphalt mixture and construction method

摘要

The present invention relates to a low noise asphalt mixture and a method for producing and mixing the asphalt mixture. The present invention relates to a low noise asphalt mixture comprising 5-10% pure asphalt, 2-7% waste tire rubber powder, 3-8% A mixture prepared by mixing one mixture and the balance% of aggregate at a temperature of 180 ° C or higher; A first step of mixing the asphalt mixture in an asphalt mixing plant; A second step of transferring the mixture mixed in the first step to the site at a speed of 40 km; The mixture transferred to the second step is mixed with 80 to 84% of asphalt materials having an invasion degree of about 35 to 50 to 16 to 20% of a mixed solution of a polypropylene polymer, a thermoplastic resin, a pohutland resin, A third step of placing the manufactured waterproof body at 150 DEG C or higher; And a fourth step of compaction of the third stage with the vibration tire rollers when the third step is completed.
