水泥稳定碎石串联式双拌缸两级拌合施工的研究与应用

水泥稳定碎石串联式双拌缸两级拌和是以混合料拌合工艺的改进研究为出发点,通过改进混合料拌合工艺后,进一步调整水泥剂量,改善了混合料材料性能,有效提高了铺筑效果,确保了工程质量,有效减少了裂缝、离析等质量通病。研究成果将更有效的促进和完善低剂量水泥抗裂型水泥稳定碎石混合料技术的应用,尤其对结构收缩应力大、有冻胀危害的寒冷地区道路施工,具有很强的借鉴意义。

Study and Application of Dual-mixing Cylinder Techniques in the Construction of Cement Stabilized Crushed Stone Basement

Through the improvement of mixing process, the dual-mixing cylinder is used in the construc-tion techniques of cement treated macadam base which can effectively improve the performance of the ma-terial mixtures, reduce the self-crack, segregation of the semi-rigid base structure and ensure the project quality. The research will contribute to improve the application of low dosage Cement Crack Resistance of cement stabilized gravel mixture technology, especially in cold area of frost heaving damage. It has great significance in promoting the construction of highway, and can provide the reference for the similar engi- neering.
