| titleOfInvention | Sound-absorbing environment-friendly recycled asphalt concrete and preparation process thereof |
| abstract | The invention discloses sound-absorbing environment-friendly recycled asphalt concrete and a preparation process thereof, relates to the technical field of asphalt concrete processing, and solves the problem that urban noise cannot be effectively reduced in the use process due to poor noise reduction stability of the asphalt concrete. The paint comprises the following components in parts by weight: 75-80 parts of new aggregate; 4-6 parts of SBS modified asphalt; 0.2-0.3 part of mineral powder; 16-22 parts of a regenerated asphalt mixed old material; 0.04-0.08 part of a regenerant; 2.5-4.5 parts of a fiber filler; 4-6 parts of high-temperature resistant sound absorption material; 3-3.5 parts of expanded vermiculite; 0.6-1.2 parts of water glass; 0.4-0.8 part of microporous calcium silicate. The sound absorption environment-friendly recycled asphalt concrete has good sound absorption and noise reduction effects, can keep good stability in the using process, and has long integral service life. |
