High-strength and high-viscosity cold-mixed and cold-laid asphalt mixture and application thereof in pavement wearing layer
The invention relates to a road maintenance material and a preparation method thereof, in particular to a high-strength and high-viscosity cold-mixed and cold-laid asphalt mixture and application thereof in a pavement wearing layer. The high-strength and high-viscosity cold-mixed and cold-laid asphalt mixture comprises the following components: coarse aggregate, fine aggregate, high-viscosity modified emulsified asphalt, high-strength filler, high-strength basalt fiber, water-based acrylic resin and water. The components of the high-strength and high-viscosity cold-mixing and cold-paving material and the special mineral aggregate grading range are adopted for configuration, mixing and paving construction is completed in the advancing process of a special paving vehicle for cold-mixing and cold-paving, and after rolling forming, high-strength bonding with an old asphalt pavement and a cement pavement can be achieved; compared with a traditional micro-surfacing wearing layer, the micro-surfacing wearing layer has the advantages of being high in strength, good in fatigue toughness, high in skid resistance, good in water sealing performance, low in driving noise and the like, and can better resist base plane crack reflection.
本发明涉及道路养护材料及制备方法，尤其涉及一种高强高粘冷拌冷铺沥青混合料及其在路面磨耗层中的应用。高强高粘冷拌冷铺沥青混合料包括如下组分：粗集料、细集料、高粘改性乳化沥青、高强填料、高强玄武岩纤维、水性丙烯酸树脂、水。采用该高强高粘冷拌冷铺材料组分及专用的矿料级配范围进行配置，采用冷拌冷铺专用摊铺车行进过程中完成拌和与摊铺施工，碾压成型后，与旧沥青路面和水泥路面均能实现高强度粘结；与传统微表处磨耗层相比，具有强度高、疲劳韧性好、抗滑性能高、封水性能好、行车噪音低等优点，且能更好抵抗基面裂缝反射的能力。
