Wear-resistant embedded type anti-skid layer of new cement concrete pavement and construction method
The invention discloses a wear-resistant embedded type anti-skid layer of a new cement concrete pavement and a construction method, and relates to the technical field of highway engineering. The wear-resistant anti-skid layer comprises a wear-resistant material embedded in the surface of the new cement concrete pavement; when being used for tunnel pavements, the wear-resistant material includes high wear-resistant aggregates, pigments and a retroreflection material, and when being applied to other parts, the wear-resistant material only includes the high wear-resistant aggregates; and the highwear-resistant aggregates are natural or artificial stones each with a polishing value of not less than 45PSV. The construction method comprises the following innovated contents: base treatment and necessary preparation work; concrete layer concrete proportion design, workability requirement, a construction method for and process control over a surface mortar layer; a construction and control method for the wear-resistant material embedded anti-skid functional layer, a uniform spreading method for the wear-resistant material, an embedding and endurance method for the wear-resistant material,a skid resistance and flatness improvement method for he wear-resistant layer, and the like; anti-slip layer curing at a plastic stage, structure treatment and the like. The anti-skid layer can save scarce natural sand resources, makes full use of recycled aggregates, and realizes changing wastes into treasures.
本发明公开一种新建水泥混凝土路面耐磨料嵌入式抗滑层及施工方法，涉及公路工程技术领域，该耐磨抗滑层包括嵌于新建水泥混凝土路面表面的耐磨料；所述耐磨料用于隧道路面时包括高耐磨骨料、颜料和逆反射材料，其他应用部位仅为高耐磨骨料；所述高耐磨骨料是磨光值不小于45PSV的天然石或人工石；该施工方法包括；基层处理和必要的准备工作；混凝土层混凝土配合比设计、工作性要求、表面砂浆层施工方法及过程控制；耐磨料嵌入抗滑功能层施工及控制方法，耐磨料的均匀洒布方法、耐磨料嵌入耐久方法、耐磨层抗滑性和平整度提升方法等；抗滑层塑性阶段养生及构造处理等创新内容。本发明可节省紧缺的天然砂资源，充分利用再生集料，实现变废为宝。
