Normal-temperature rapid repairing material for asphalt pavement rut diseases and repairing method of normal-temperature rapid repairing material
The invention relates to the technical field of pavement rut repairing, in particular to a normal-temperature rapid repairing material for asphalt pavement rut diseases and a repairing method of the normal-temperature rapid repairing material. The rapid repairing material comprises the following raw materials: modified emulsified asphalt, rapid cement, coarse aggregate and fine aggregate. The rapid repairing material provided by the invention does not need to add water during mixing, the emulsified asphalt forms strength after demulsification, water required by cement hydration is provided, the activity of the quick cement can promote demulsification of the emulsified asphalt, and the quick cement and the emulsified asphalt jointly accelerate the final setting time of the repair material and quickly improve the early strength. The rapid repairing material is suitable for repairing high-traffic-volume and serious-overload asphalt pavement ruts and pit slots, has the characteristics of no need of traffic closing, high early strength, good toughness, strong binding power, strong durability and impact resistance, small environmental influence on construction and the like, and can be finally set to form strength generally 20 minutes after mixing.
本发明涉及路面车辙修复技术领域，具体地说，涉及一种沥青路面车辙病害常温快速修复材料及其修复方法。该快速修复材料的原材料组成包括改性乳化沥青、快速水泥、粗集料、细集料。本发明所提供的快速修复材料拌和无需要加水，乳化沥青破乳后形成强度，并提供水泥水化所需水，快速水泥具有的活性能促进乳化沥青破乳，二者共同加快修复材料终凝时间和快速提高早期强度；适用于高交通量、超载严重的沥青路面车辙坑槽修补工作，其具有无需封闭交通、早期强度高、韧性好、粘结力强、耐久抗冲击性能强、施工受环境影响小等特点，通常从拌和起20分钟即可终凝形成强度。
