水泥混凝土路面全厚式移动破碎就地冷再生工艺流程共分为破碎和再生两个环节，预破、一破、二破（前三步为破碎环节）、添加新集料（如有需要）、水泥+再生剂+活性剂撒布、再生拌和、初压、整形、终压、养生（后七步为再生环节）10大步骤组成。

The on-site cold recycling process of full thickness mobile crushing for cement concrete pavement is divided into two steps: crushing and recycling. The first three steps are crushing, adding new aggregates (if necessary), spreading cement+rejuvenator+active agent, recycling mixing, initial pressing, shaping, final pressing, and curing (the last seven steps are recycling).

（1)预破：是指利用路面破板机（俗称“啄木鸟”）或者多锤头等（根据不同路段的路侧环境灵活运用）对旧水泥混凝土路面板进行简易破碎，为后续的就地破碎设备提供附着力。农村公路等水泥路面板不厚，强度不高的情况下，可无需预破。预破在破碎作业前开展作业，预破后的作业面，及时用压路机静压和振压各一遍，可供通勤车辆慢速通行，防止扎破轮胎。

(1) Pre breaking: refers to the use of road surface breaking machines (commonly known as "woodpeckers") or multi hammer heads (flexibly applied according to the roadside environment of different road sections) to easily break old cement concrete pavement panels, providing adhesion for subsequent on-site crushing equipment. When the cement pavement panels on rural roads are not thick and have low strength, there is no need for pre cracking. Pre crushing operations shall be carried out one day before the crushing operation. After pre crushing, the working surface shall be promptly subjected to static pressure and vibration pressure with a road roller, which can be used for slow traffic of commuting vehicles to prevent tire puncture.

（2）一破：是指利用全厚式移动破碎机，对经过预破的路面进行次全厚式移动破碎，形成10厘米左右的粗破碎料。破碎机转子旋转方向与行车方向一致，避免了铣刨类设备针片状含量高、设备损耗大、综合作业效率低的缺陷。破碎厚度通过电子标尺精确控制并带自动保护装置，如未破碎到底，则设备不行走。通常一个班组2~3台，日均作业4000~5000。

(2) One break: refers to the use of a full thickness mobile crusher to perform the first full thickness mobile crushing on the pre broken road surface, forming coarse crushed materials of about 10 centimeters. The rotation direction of the crusher rotor is consistent with the driving direction, avoiding the defects of high needle like content, large equipment loss, and low overall operational efficiency in milling and planing equipment. The crushing thickness is precisely controlled by an electronic ruler with an automatic protection device. If it is not completely crushed, the equipment will not move. Usually, a team consists of 2-3 units, with an average daily work area of 4000-5000 square meters.

（3）二破：是指利用全厚式移动破碎机，对经过一破后的路面进行第二次全厚式移动破碎，通过调整二破设备的行进速度、转子转速、刀头数量和粗细等进行组合，终使得二破后的集料满足水稳基层级配要求。

(3) Second crushing: refers to the use of a full thickness mobile crusher to perform a second full thickness mobile crushing on the road surface after passing through the first crushing. By adjusting the traveling speed, rotor speed, number and thickness of cutting heads of the second crushing equipment, the final aggregate after the second crushing meets the requirements of water stable foundation gradation.

二破设备与一破设备性质类似，只是转子、刀头、设备功率、转速等存在差异，转子方向与一破相反，刀头略小。通常一个班组1台，日均作业4000~5000。二破设备通过反击破+搓揉作用，可剥离粗集料表面的水泥砂浆，尽量保持原级配不变。

The nature of the second breaking equipment is similar to that of the first breaking equipment, except for differences in rotor, blade, equipment power, speed, etc. The rotor direction is opposite to that of the first breaking equipment, and the blade is slightly smaller. Usually one team has one unit, with an average daily work area of 4000~5000 square meters. The secondary crushing equipment can peel off the cement mortar on the surface of coarse aggregates through counterattack and rubbing, while keeping the original grade as unchanged as possible.

（4）添加新集料：添加新料的数量和级配，综合考虑设计厚度、级配范围，通过筛分和计算得到。对于单一粒径的集料可以采用堆方方法，通过挖机、铲车和平地机铺展，多档集料必须逐档单独添加，避免堆放和铺展过程中产生离析。添加新集料后的路面必须用压路机进行初步压实。

(4) Add new aggregate: The quantity and grading of the new aggregate are determined by screening and calculation, taking into account the design thickness and grading range. For single particle size aggregates, the stacking method can be used to spread them out using excavators, forklifts, and flat ground machines. Multi grade aggregates must be added separately in each grade to avoid segregation during stacking and spreading. The road surface after adding new aggregates must be preliminarily compacted with a roller.

（5)水泥+再生剂+活性剂撒布：是指采用粉料撒布车，将水泥+再生剂+活性剂等精确撒布破碎后（或者添加新集料后的）路面，粉料撒布车通过电脑控制，以确保撒布的精确性和均匀性。水性再生剂和活性剂也可参入水中进行掺配。水泥、再生剂和活性剂用量通过配合比试验确定，通常每平米每厘米厚度水泥用量不超过1kg。水泥通常采用P.042.5#即可。

(5) Cement+rejuvenator+activator spreading: refers to the use of a powder spreading vehicle to accurately spread cement+rejuvenator+activator, etc. onto the crushed (or newly added aggregate) road surface. The powder spreading vehicle is controlled by a computer to ensure the accuracy and uniformity of the spreading. Water based regenerants and activators can also be added to water for blending. The dosage of cement, rejuvenator, and activator is determined through mix proportion testing, and usually the dosage of cement per square meter per centimeter thickness does not exceed 1kg. Cement usually uses P.042.5 #.

（6）再生拌和：是指采用就地冷再生机，将破碎集料（含添加的新集料）、撒布的水泥、再生剂、活性

(6) Regenerative mixing: refers to the use of on-site cold recycling machines to mix crushed aggregates (including newly added aggregates), scattered cement, rejuvenators, and activated materials
