Low-noise asphalt pavement mixture and low-noise pavement construction method
The invention relates to the technical field of pavement materials, and particularly discloses a low-noise asphalt pavement mixture and a low-noise pavement construction method. Comprising the following raw materials in parts by weight: 6-10 parts of modified asphalt, 120-170 parts of aggregate, 2-4 parts of water, 3-7 parts of filler, 3-8 parts of rubber particles and 0.05-0.1 part of a stabilizer, the gradation of the aggregate is as follows: 100% of particles passing through a 16 mm mesh sieve, 85-100% of particles passing through a 13.2 mm mesh sieve, 55-75% of particles passing through a 9.5 mm mesh sieve, 11-26% of particles passing through a 4.75 mm mesh sieve, 6-11% of particles passing through a 2.36 mm mesh sieve and 2-4% of particles passing through a 0.075 mm mesh sieve; and the mesh degree of the rubber particles is 4-30 meshes. The basic performance of the asphalt mixture is improved, meanwhile, the damping sound absorption capacity of the asphalt pavement is remarkably improved, and the noise of the asphalt pavement is reduced.
本申请涉及路面材料技术领域，具体公开了一种低噪音沥青路面混合料及低噪音路面施工方法。包括以下重量份的原料：改性沥青6‑10份、集料120‑170份、水2‑4份、填料3‑7份、橡胶颗粒3‑8份和稳定剂0.05‑0.1份；所述集料的级配为：通过16mm孔筛的颗粒100％，通过13.2mm孔筛的颗粒85‑100％，通过9.5mm孔筛的颗粒55‑75％，通过4.75mm孔筛的颗粒11‑26％，通过2.36mm孔筛的颗粒6‑11％，通过0.075mm孔筛的颗粒2‑4％；所述橡胶颗粒的目度为4‑30目。本申请在改善沥青混合料的基本性能的同时显著提高沥青路面的阻尼吸音能力，降低沥青路面的噪音。
