沥青基改性剂对灌注式半柔性路面性能影响的研究

Study on the Influence of Asphalt Base Modifier on The Performance of Perfused Semi-Flexible Pavement

本文提供一种高分子沥青基再分散改性剂,通过其在水泥基材料中的成膜反应,形成成片包裹水泥基材料的油膜,油膜阻止水分子和腐蚀性分子的扩散,因此提升了半柔性路面抗渗、抗盐腐性能,由于高分子弹性体的存在,半柔性路面的抗裂性能也同时得到改善。

This article discusses a polymer asphalt-based redispersion modifier.The modifier forms a bituminous oil film in cement-based materials.The oil film wraps the cement cementitious material and prevents the diffusion of water molecules and corrosive molecules.Therefore,the impermeability and salt corrosion resistance of the semi-flexible pavement are improved.Due to the existence of the polymer elastomer,the crack resistance of the semi-flexible pavement is also improved.
