1、易密实沥青混合料在公路预防性养护中的应用Application of modified asphalt mixture in preventive maintenance of highways一、引言Introduction随着我国经济的发展和交通运输的快速发展，公路上的车辆数量不断增加，公路网的维护难度也提高了。交通管理部门需要更多的资金来维护公路，以确保其安全、高效和经济。传统的养护方法不仅昂贵，而且过于依赖于维护人员的经验，而忽略掉公路预防性养护的重要性。With the development of economy and the rapid development of trans

2、portation and transportation in our country, the number of vehicles on the highway is increasing, and the difficulty of maintaining highway network is also increasing. The traffic management department needs more funds to maintain the highway to ensure its safety, efficiency and economy. Traditional

3、 maintenance methods are not only expensive, but also too dependent on the experience of maintenance personnel, ignoring the importance of preventive maintenance of highways.预防性养护是一种可以在公路网未发生显著变化时，就采取维护措施，以在未来阻止其发生损坏的行为。改性沥青混合料是道路养护的理想材料，它可以在路面上形成一层护盾，有效地阻止因水蚀、沉降、摩擦磨损等原因而造成的损坏。Preventive maintenance

4、 is a kind of maintenance measures taken to prevent damage from happening in the future when there is no significant change in the highway network. Modified asphalt mixture is an ideal material for road maintenance. It can form a shield on the road surface to effectively prevent damage caused by water erosion, settlement, frictional wear and other reasons.二、原变沥青混合料的特点2. Features of original modified asphalt mixture改性沥青混合料具有高抗裂性、高抗冻性、高耐磨性、高抗水渗能力、耐臭性良好、安装简便速度快等特点。它还能很好地抗拉伸和膨胀，减少公路表面的凹凸不平，防止路面局部损坏。改性沥青混合料还能有效地降低公路表面的温度，从而避免表面的热裂。此外，改性沥青混合料是一种抗腐蚀的材。
