该项新工艺技术将刚性的水泥路面就地直接改造成了半刚性的水稳基层，避免了传统的水泥路面碎石化后加铺新水稳基层或者ATB柔性基层等技术方案带来的一系列弊端。具有如下显著的比较优势：

This new process technology directly transforms the rigid cement pavement into a semi-rigid water stable base layer on site, avoiding a series of drawbacks caused by traditional cement pavement fragmentation and the addition of new water stable base layer or ATB flexible base layer. Has the following significant comparative advantages:

（1)低碳环保节更能：与传统的场破场拌再生只利用旧路面的粗集料不同，该技术旧水泥路面材料100%完全利用，而且再生后直接作为沥青路面最重要的承重结构层——基层，而不是传统的用作底基层，即无需在加铺新的水稳类机构层，而是可以直接加铺沥青面层，完全符合国家绿色、低碳新发展理念，也符合交通运输部路面废旧材料必须100%循环利用的要求。

(1) Low carbon environmental protection is more effective: Unlike traditional field breaking and mixing recycling that only uses coarse aggregates from old road surfaces, this technology fully utilizes 100% of old cement pavement materials and directly uses them as the most important load-bearing structural layer of asphalt pavement - the base layer, instead of the traditional bottom layer, which does not require the addition of new water stable structural layers, but can directly add asphalt surface layers, fully in line with the national green and low-carbon new development concept, and also meets the requirement of the Ministry of Transport that road waste materials must be 100% recycled.

（2）路面标高抬升小：相较于传统的碎石化加铺方案，该技术路面标高抬升幅度下降约2/3（跟板厚有关），大大降低了因标高抬升幅度过大而导致的路面有效宽度不足、水沟深度加大、护栏难以设置、平交道口难以接顺、施工工期较长，易造成公路管养部门与沿线居民的矛盾等一系列问题。

(2) Small elevation rise of road surface: Compared with the traditional crushed stone paving scheme, this technology reduces the elevation rise of the road surface by about 2/3 (related to the thickness of the slab), greatly reducing a series of problems caused by insufficient effective width of the road surface, increased depth of ditches, difficulty in setting guardrails, difficulty in connecting level crossings, long construction period, and conflicts between highway management and maintenance departments and residents along the line due to excessive elevation rise.

（3）消除隐患更彻底：旧水泥混凝土路面板破碎彻底，而且所有过程均可视化，彻底消除了传统碎石化“隐蔽工程”性质的弊端，彻底消除了碎石化不彻底、难以有效检验其效果、工后产生反射裂缝等诸多弊端、碎石化结构层本身不具有长寿命性能，为下一轮大修埋下严重隐患等缺陷。水泥混凝土路面再生成水稳基层后，下一轮大修时可对水稳基层再次进行再生循环利用，可大大降低路面全寿命周期的养护成本，具有显著的社会经济效益。

(3) Eliminating hidden dangers more thoroughly: The old cement concrete pavement slab is completely broken, and all processes can be visualized, completely eliminating the drawbacks of traditional "hidden engineering" properties of crushed stone. It completely eliminates many drawbacks such as incomplete crushed stone, difficult to effectively test its effect, reflection cracks after construction, and the fact that the crushed stone structural layer itself does not have long-life performance, which poses serious hidden dangers for the next round of major repairs. After the cement concrete pavement generates a water stable base layer, it can be recycled and reused in the next round of major repairs, which can greatly reduce the maintenance cost of the pavement throughout its entire life cycle and have significant social and economic benefits.

（4）施工作业影响：施工作业振动小、噪音小、扬尘少，对沿线房屋建筑、桥涵构造物、板下基层等损害几乎没有，对沿线学校、村镇居民的正常生产生活影响较小。更主要的是，可完全满足半幅施工半幅双向间断通行的要求。（5）节省造价有优势：与同厚度新铺水稳基层相比较，节省造价15%～20%（跟碎石等地材价格有关）；跟碎石化加铺ATB柔性基层技术方案相比较，大修补助标准高30元/平方米。

(4) Construction operation impact: The construction operation has minimal vibration, noise, and dust, causing almost no damage to buildings, bridge and culvert structures, and sub base layers along the line. It has a relatively small impact on the normal production and life of schools and rural residents along the line. More importantly, it can fully meet the requirements of half width construction and half width bidirectional intermittent traffic. (5) Cost saving has advantages: compared with the newly laid water stable base of the same thickness, it saves 15% to 20% of the cost (related to the price of ground materials such as gravel); Compared with the technology scheme of adding ATB flexible base layer to crushed stone, the subsidy standard for major repairs is 30 yuan/square meter higher.

（6）施工作业效率高：日台班3000~4000平方米，相较于碎石化加铺技术方案缩短工期约1/4~1/3。

(6) High construction efficiency: daily shift of 3000~4000 square meters, which shortens the construction period by about 1/4~1/3 compared to the crushed stone paving technology scheme.

（7)质量效果非常优：大量的工程时间表明，采用该项新工艺技术路面取芯效果非常好，通常7天无侧限抗压强度不低于5MPa，代表弯沉值不超过20（0.01mm)，压实度、平整度、平纵横计文件要烈情况远低干传统的等指标古或考求普诵新铺水稳

(7) The quality effect is very excellent: a large amount of engineering time has shown that the use of this new process technology for road surface coring has a very good effect. Usually, the unconfined compressive strength is not less than 5MPa after 7 days, and the representative deflection value does not exceed 20 (0.01mm). The compactness, flatness, and longitudinal and transverse meter files are much lower than traditional indicators, such as water stability
