轻骨料混凝土是一种比较理想的建筑材料,具有轻质、保温、隔热等诸多优点。它是由粘土陶粒、粉煤灰陶粒等粗骨料以及常用的砂、水泥、水等材料制作而成。目前已广泛应用于桥梁以及各种工业民用建筑上,将陶粒使用于沥青混凝土意义在于陶粒与普通石料相比较具有比重轻,陶粒沥青混凝土用作桥面铺装,能够减轻铺装层荷载,具有显著的实效意义。其次,陶粒表面具有较粗的纹理,增大集料的表面摩擦系数,可以阻止混合料颗粒之间的移动,提高混合料的强度,陶粒沥青混凝土用作桥面铺装,能够减轻铺装层荷载,具有显著的实效意义。
Lightweight aggregate concrete is a kind of ideal building material, with many advantages such as light weight, heat preservation and heat insulation. It is made of clay ceramic, fly ash ceramsite and other coarse aggregate, as well as commonly used sand, cement, water and other materials made. Has been widely used in bridges and various industrial civil buildings, the use of ceramsite in asphalt concrete significance is that compared with ordinary stone ceramsite light weight, ceramic asphalt concrete used as a bridge deck pavement, can reduce the pavement Load, with significant practical significance. Secondly, the surface of the ceramsite has thick texture, increasing the surface friction coefficient of the aggregate can prevent the movement between the mixture particles and improve the strength of the mixture, and the ceramic ceramsite asphalt concrete can be used as a bridge deck pavement, Laying load, with significant practical significance.
