通过改变路面结构设计和施工工艺提高沥青与集料的粘附性水侵害是沥青路面损坏的主要原因，其作用机理是:

Improving the adhesion between asphalt and aggregates through changes in pavement structure design and construction techniques. Water damage is the main cause of asphalt pavement damage, and its mechanism of action is:

在水的作用下，济南沥青料逐渐丧失与矿料的粘结力，从矿料表面脱落，并在车辆的作用下，沥青面层呈现松散状态，形成水损害。水损害产生的原因通常有下列几种：路面排水系统不健全；路面压实度不足；路面离析；半刚性基层反射裂缝造成雨水的渗入；路面结构设计不合理等。

Under the action of water, Jinan asphalt gradually loses its bonding force with the mineral material, detaches from the surface of the mineral material, and under the action of vehicles, the asphalt surface layer appears loose, forming water damage. There are usually several reasons for water damage: the road drainage system is not sound; Insufficient compaction of the road surface; Road segregation; Reflection cracks in the semi rigid base layer cause rainwater infiltration; Unreasonable pavement structure design, etc.

从设计角度讲，主要是设计健全的路面排水系统，若采用排水路面则须在沥青面层的下层用沥青含量高的沥青砂做下封层，其厚度应不小于2—2.5cm；优化路面结构；采用抗裂性好的基层，如水稳碎石等；采取措施减小半刚性基层反射裂缝造成的影响；采用SMA等新型防水性好、耐久的路面面层等。

From a design perspective, the main focus is on designing a sound road drainage system. If a drainage road surface is used, a high asphalt content asphalt sand layer must be used as a lower seal layer on the lower layer of the asphalt surface layer, and its thickness should not be less than 2-2.5cm; Optimize the pavement structure; Using a base layer with good crack resistance, such as water stabilized crushed stone; Take measures to reduce the impact of reflective cracks on semi rigid base layers; Adopting new waterproof and durable road surface layers such as SMA.

从施工角度讲，主要是优化施工工艺，提高沥青路面施工时的压实度和平整度。

From a construction perspective, the main focus is to optimize the construction process and improve the compaction and smoothness of asphalt pavement construction.

使用化学抗剥剂提高沥青与集料的粘附性

Improving the adhesion between asphalt and aggregates using chemical anti stripping agents

随着表面化学的发展，各种表面活性剂的开发，也已经开发了许多抗剥剂。实践证明，在沥青中添加大量环烷酸类高分子有机酸，尤其是添加钙、镁、铅，锰等各种类型 的金属皂，能够有效提高沥青与集料的粘附性。抗剥剂通过亲油基与沥青结合，亲水基与集料结合，使沥青与集料的粘附性得以提高，所以对集料表面带有负电荷的应采用阳离子型，表面带有正电荷的应采用阴离子型的表面活性剂，才能起到好的效果。由于酸性石料带有负电荷，抗剥离剂一般采用阳离子型的表面活性剂，当然这就使碱性石料采用抗剥落剂显得无能为力，而且对碱性石料也没有此种必要。

With the development of surface chemistry and the development of various surfactants, many anti stripping agents have also been developed. Practice has proved that the adhesion between asphalt and aggregate can be effectively improved by adding a large amount of naphthenic acid polymer organic acids, especially various types of Metallic soap such as calcium, magnesium, lead and manganese. Anti stripping agents combine with asphalt through hydrophilic groups, while hydrophilic groups combine with aggregates to improve the adhesion between asphalt and aggregates. Therefore, cationic surfactants should be used for aggregates with negative surface charges, while anionic surfactants should be used for aggregates with positive surface charges to achieve good results. Due to the negative charge of acidic stones, cationic surfactants are generally used as anti stripping agents. Of course, this makes it powerless for alkaline stones to use anti stripping agents, and there is no such necessity for alkaline stones.

综上所述，只要在沥青路面设计和施工时，采取相应的改善措施，对于提高沥青与集料的粘附性，防范沥青路面的水损坏效果还是比较明显的。

In summary, as long as corresponding improvement measures are taken during the design and construction of asphalt pavement, the effect of improving the adhesion between asphalt and aggregates and preventing water damage to asphalt pavement is still quite obvious.

在施工时，往往同时采用两种或两种以上的综合处理方法比单独一种效果要比较好。如选择低标号沥青或使用改性沥青，并同时用石灰水处理粗集料；采用掺加抗剥剂并用水泥替代部分矿粉；用石灰水处理粗集料同时用水泥替代部分矿粉等。更多相关事项就来我们网站咨询！

During construction, it is often better to use two or more comprehensive treatment methods simultaneously than a single one. For example, low-grade asphalt or modified asphalt shall be selected and Limewater shall be used to treat the coarse aggregate at the same time; Adopting the addition of anti stripping agents and replacing some mineral powder with cement; Limewater is used to treat coarse aggregate and cement is used to replace part of mineral powder.
