Large-particle-size cement stabilized macadam and method thereof
The invention discloses large-particle-size cement stabilized macadam and a method thereof. The large-particle-size cement stabilized macadam comprises the following components in parts by weight: 25-35 parts of first broken stone; 20-30 parts of second broken stone; 15-25 parts of third broken stone; 20-30 parts of stone chips; 1-8 parts of cement; and 1-8 parts of water, wherein the particle size of the first broken stone is 19-37.5 mm, the particle size of the second broken stone is 9.6-19 mm, and the particle size of the third broken stone is 4.75-9.5 mm; the method comprises the following steps: S1, preparing raw materials of broken stone, stone chips, cement and water; s2, mixing a mixture; before the mixture is formally blended, blending equipment is debugged, and trial blending is carried out, so that the particle composition and the water content of the mixture meet the specified requirements; the water content of the aggregate is checked before mixing every day, the construction mix proportion of the day is calculated, all the materials prepared in the step S1 are classified according to the mix proportion and put into all stock bins, and the blending proportion of all the materials is controlled through the stock bins; coarse aggregate, fine aggregate, cement and water in each bin are mixed in th mixing bin according to a ratio; s3, performing vibration forming of the vibration mixing cylinder, and finally discharging through a conveying belt; the invention provides the cement stabilized macadam which is low in cost, high in strength, anti-cracking and anti-freezing and the method thereof.
本发明公开一种大粒径水泥稳碎石及其方法，大粒径水泥稳碎石包括以下组分及其重量份：第一碎石25‑35份；第二碎石20‑30份；第三碎石15‑25份；石屑20‑30份；水泥1‑8份；水1‑8份，其中，第一碎石的粒径为19‑37.5mm，第二碎石的粒径为9.6‑19mm，第三碎石的粒径为4.75‑9.5mm；方法包括S1、配置原料碎石、石屑、水泥和水；S2、混合料拌制；混合料在正式拌和之前，先调试拌和设备，进行试拌，使混合料的颗粒组成和含水量都达到规定的要求；每天拌合前检查集料含水率，计算当天施工配合比，按配合比将步骤S1准备的各类材料分类放至各个料仓，通过料仓控制各类材料掺配比例；先将各料仓中的粗集料、细集料、水泥、水按比例在拌合仓中拌合；S3、振动拌缸经振动成型，最后通过传输带出料；本发明提供了一种成本低、强度高、抗裂、防冻的水泥稳碎石及方法。
