该技术主要针对旧水泥路面（如“白改黑”工程），利用移动破碎设备将刚性水泥路面全厚度破碎，就地改造成半刚性的水泥稳定碎石基层。

This technology is mainly aimed at old cement pavements (such as the "white to black" project), using mobile crushing equipment to fully crush the rigid cement pavement and transform it into a semi-rigid cement stabilized crushed stone base on site.

预破与一破：利用路面破板机（俗称“啄木鸟”）或多锤头对旧水泥面板进行简易破碎，为后续设备提供附着力；随后进行第一次全厚式破碎。

Pre breaking and first breaking: using a road breaking machine (commonly known as a "woodpecker") or multiple hammers to easily break old cement panels, providing adhesion for subsequent equipment; Subsequently, the first full thickness crushing is carried out.

精细化二破：使用全厚式移动破碎机进行第二次破碎。通过调整转子转速、刀头等参数，利用反击破与搓揉作用剥离粗集料表面的水泥砂浆，使骨料粒径和级配满足水稳基层要求。

Refined secondary crushing: Use a full thickness mobile crusher for the second crushing. By adjusting the rotor speed and blade head parameters, the cement mortar on the surface of the coarse aggregate is peeled off using the impact breaking and kneading effects, so that the particle size and gradation of the aggregate meet the requirements of a water stable base layer.

添加新集料与粉料：根据设计补充新碎石以优化级配，并使用粉料撒布车精确、均匀地撒布水泥、再生剂及活性剂。

Add new aggregates and powders: Add new crushed stones according to the design to optimize the grading, and use a powder spreader to accurately and evenly spread cement, rejuvenator, and activator.

再生拌和与压实：采用就地冷再生机将破碎料与粉料就地拌和成水稳混合料。随后使用大吨位羊足碾进行初压，平地机精准调平，最后用单钢轮和胶轮压路机组合进行终压收光。

Regeneration mixing and compaction: The crushed material and powder material are mixed on-site using a cold recycling machine to form a water stable mixture. Subsequently, a large tonnage sheep foot roller is used for initial compaction, a grader is used for precise leveling, and finally a combination of single steel wheel and rubber wheel rollers is used for final compaction and finishing.

保湿养护：施工完成后进行保湿养护，通常3~7天后基层即可具备较高强度并满足通车或面层施工条件。

Moisturizing maintenance: Moisturizing maintenance should be carried out after construction is completed. Usually, the base layer can have high strength and meet the conditions for traffic or surface construction after 3-7 days.
