Anti-cracking pavement base material, preparation method and construction process
The invention discloses an anti-cracking pavement base material, a preparation method and a construction process, and belongs to the field of building materials. The pavement base material comprises the following components in percentage by weight: 5-8% of cement, 0.5-1% of steel fibers, 0.3-0.5% of a bidirectional fiber mesh, 1-3% of nano zinc oxide, 1-2% of an exciting agent, 6-10% of water and the balance of a cementing material, the cementing material is formed by compounding and compacting broken stone, fly ash and modified asphalt according to the mass ratio of (15-20): (3-5): (1-3). The anti-cracking pavement base material disclosed by the invention has relatively good compressive strength and good anti-cracking performance, and completely meets the requirements of highway roadbeds and paving layers.
本发明公开了一种防裂路面基层材料、制备方法及施工工艺，属于建筑材料领域。所述路面基层材料包括以下重量百分比的组分：水泥5～8％、钢纤维0.5～1％、双向纤维网0.3～0.5％、纳米氧化锌1～3％、激发剂1～2％、水6～10％，余量为胶结料；所述胶结料由碎石、粉煤灰、改性沥青以15～20：3～5：1～3的质量比复配压实而成。本申请的防裂路面基层材料具有较好抗压强度和良好的防裂性能，完全满足公路路基和铺层的要求。
