Rubber cement stabilized macadam mixture and construction method thereof
The invention belongs to the field of cement stabilized macadam, and particularly relates to a rubber cement stabilized macadam mixture which comprises mineral aggregate, rubber particles, cement and water, the content of the rubber particles accounts for 1%-3% of the total mass of the mineral aggregate, the mineral aggregate is continuously graded within the particle size range of 0-26.5 mm, and the cement accounts for 1%-2% of the total mass of the mineral aggregate. The mineral aggregate is divided into 12 grades from high to low according to the particle size; the rubber particles replace mineral raw materials with the same particle size within the particle size range of 2.36-9.5 mm in an equal-volume mode; the invention also relates to a construction method of the rubber cement stabilized macadam mixture. By adding the rubber particles into the cement stabilized macadam, on the basis of ensuring the strength of the cement stabilized macadam semi-rigid base material, the toughness of the cement stabilized macadam semi-rigid base material can be improved, the rigidity difference of each structural layer of a pavement is relieved, the crack resistance of the cement stabilized macadam semi-rigid base material is effectively improved, and pavement reflection cracks caused by base cracking are reduced; the resource consumption and the construction and maintenance cost of the whole life cycle of the pavement are greatly reduced.
本发明属于水泥稳定碎石领域，具体涉及一种橡胶水泥稳定碎石混合料，包括矿物集料、橡胶颗粒、水泥和水，所述橡胶颗粒的含量为所述矿物集料总质量的1％～3％，所述矿物集料为0～26.5mm粒径范围内的连续级配，所述矿物集料按照粒径大小由高到低分成12档；橡胶颗粒等体积替换2.36～9.5mm粒径范围内相同粒径的矿物原料；本发明还涉及上述橡胶水泥稳定碎石混合料的施工方法；本发明通过在水泥稳定碎石中加入橡胶颗粒，在确保其强度的基础上，可以增加水泥稳定碎石半刚性基层材料的韧性，缓解路面各结构层刚度差异性，有效提高其抗裂性能，减少因基层开裂引起的路面反射裂缝，大幅降低路面全寿命周期的资源消耗与建养成本。
