Cold recycled asphalt for bridge deck and production method thereof
The invention relates to the technical field of cold recycled asphalt, in particular to cold recycled asphalt for a bridge deck and a production method thereof, and aims to solve the problem that thequality of the cold recycled asphalt in the prior art is not good enough. The cold recycled asphalt is prepared from the following components in parts by weight: 4.5 parts of modified emulsified asphalt; 86 parts of aggregate; 1.5 parts of cement; 3.5 parts of mineral powder; 4.5 parts of water. The production method of the cold recycled asphalt comprises the following steps: 1, preparing modifiedemulsified asphalt; 2, adding the modified emulsified asphalt, the aggregate, the cement and the mineral powder into a stirring device according to the proportion; and 3, adding the water into the stirring device in the step 2 according to the proportion, and uniformly stirring the components to obtain the cold recycled asphalt. The modified emulsified asphalt is added into the components of thecold recycled asphalt, and the quality of the cold recycled asphalt can be greatly improved by adding the modified emulsified asphalt, so that the cracking phenomenon of a bridge deck can be reduced,and the service life of the bridge deck is prolonged.
本发明涉及冷再生沥青的技术领域，具体是一种用于桥面使用的冷再生沥青及其生产方法，用于解决现有技术中冷再生沥青的质量不够好的问题。本发明按照重量份数计包括以下组分：改性乳化沥青：4.5份；集料：86份；水泥：1.5份；矿粉：3.5份；水：4.5份；冷再生沥青的生产方法，包括如下步骤：步骤1：制备改性乳化沥青；步骤2：将改性乳化沥青、集料、水泥和矿粉按照上述比例加入搅拌装置中；步骤3：再向步骤2中的搅拌装置中加入上述比例的水，并将上述组分搅拌均匀即可制得冷再生沥青。本发明中通过向冷再生沥青的组分中加入改性乳化沥青，改性乳化沥青的加入可以极大的提高冷再生沥青的质量，从而可以减少桥面的开裂现象，提高桥面的使用寿命。
