Joint and layer treatment method of asphalt concrete core wall in high altitude area
The invention relates to a joint and layer treatment method of an asphalt concrete core wall in a high altitude area, in joint treatment, transverse joints of the asphalt concrete core wall are reduced, when the transverse joints appear, the combination gradient of the transverse joints is made into a slope with the gradient being less than 1: 3, the transverse joints of the upper layer and the lower layer are staggered by more than 2 m, and rainwater deposition is reduced; in the layer surface treatment, the surface of normal concrete is kept rough and flat, rough surface treatment is conducted, laitance, milk skin, waste residues and adhesive substances on the surface of the normal concrete are all removed, bituminous mortar or diluted asphalt is smeared on the surface, the diluted asphalt needs to be smeared evenly, no blank or block mass exists, the color is consistent, and the thickness of the surface of each square meter of the normal concrete needs to be adjusted. The use amount of the diluted asphalt is 0.2 kg, the thickness of the coated asphalt mortar is 10-20 mm, the surface of the asphalt mortar is free of bumps and flowing, and the asphalt mortar is smooth and smooth, so that the construction quality can be improved, and the influence of the environment on the construction can be reduced.
本发明涉及一种高海拔地区的沥青混凝土心墙的接缝及层面处理方法，接缝处理中，减少沥青混凝土心墙的横向接缝，当出现所述横向接缝时，其结合坡度做成缓于1：3的斜坡，上下层横缝错开2m以上，减少雨水淤积；层面处理中，常态混凝土表面保持粗糙平坦，做毛面处理，将所述常态混凝土表面的浮浆、乳皮、废渣及黏着物全部清除，表面涂抹沥青砂浆或稀释沥青，涂抹稀释沥青时要涂抹均匀、无空白、无团块、色泽一致，每平方米的所述常态混凝土表面，稀释沥青的用量为0.2kg，涂抹沥青砂浆的厚度为10～20mm，沥青砂浆的表面无鼓包，无流淌，且平整光顺，有利于提高施工质量，降低环境对施工的影响。
