来源：http://www.ycgjglcl.com/ 日期：2025-05-19
在道路基层施工中，水稳料（水泥稳定碎石）与压路机的关系，犹如琴弦与演奏家的共鸣——唯有精准匹配，才能奏出密实度的“完美乐章”。水稳料的粒径级配、含水量与水泥剂量，决定了压路机的选型、操作方式与性能边界。这种“默契配合”，既是对材料科学的尊重，也是对施工艺术的诠释。
In the construction of road subgrade, the relationship between water stabilized materials (cement stabilized crushed stones) and rollers is like the resonance between strings and musicians - only precise matching can play the "perfect melody" of compactness. The particle size distribution, moisture content, and cement dosage of water stable materials determine the selection, operation mode, and performance boundary of road rollers. This kind of 'tacit cooperation' is not only a respect for material science, but also an interpretation of construction art.
第一重匹配：压路机类型与水稳料特性的“对话”
First Matching: Dialogue between Roller Type and Water Stable Material Characteristics
水稳料的骨料粒径（通常5-31.5mm）与级配曲线，直接决定了压路机的“体型”。对于粗骨料含量超过60%的级配，需选用自重≥18吨的振动压路机，其激振力可穿透骨料间隙，形成“骨架密实”结构；而细骨料占比高的水稳料，则更适合轮胎压路机，通过柔性揉搓减少离析风险。
The aggregate particle size (usually 5-31.5mm) and grading curve of water stable materials directly determine the "shape" of the roller. For gradations with a coarse aggregate content exceeding 60%, a vibratory roller with a self weight of ≥ 18 tons should be selected, whose excitation force can penetrate the gaps between the aggregates and form a "skeleton dense" structure; Water stable materials with a high proportion of fine aggregates are more suitable for tire rollers, reducing the risk of segregation through flexible kneading.
更关键的是压路机的工作宽度。水稳层摊铺宽度每增加1米，压路机需延长0.3米的碾轮宽度，以避免边缘漏压。这种“宽度适配”原则，如同为摊铺机与压路机定制“情侣装”，确保压实无死角。
More importantly, the working width of the roller. For every 1 meter increase in the paving width of the water stable layer, the roller needs to extend the roller width by 0.3 meters to avoid edge leakage. This principle of "width adaptation" is like customizing "couple outfits" for pavers and rollers, ensuring that there are no dead corners in compaction.
第二重匹配：振动参数与水稳料响应的“共振”
Second Matching: Resonance between Vibration Parameters and Water Stable Material Response
压路机的振动频率与振幅，是激活水稳料密实度的“钥匙”。频率需与骨料粒径成反比——粒径越大，频率越低（通常25-35Hz），以避免骨料破碎；振幅则需与水稳料厚度成正比——每10cm厚度需对应0.5mm振幅，确保振动波能穿透至底层。
The vibration frequency and amplitude of the roller are the key to activating the compactness of water stable materials. The frequency should be inversely proportional to the particle size of the aggregate - the larger the particle size, the lower the frequency (usually 25-35Hz) to avoid aggregate crushing; The amplitude should be proportional to the thickness of the water stable material - every 10cm thickness should correspond to an amplitude of 0.5mm to ensure that the vibration wave can penetrate to the bottom layer.
这种“共振”效应在复压阶段尤为关键。当压路机以1.5-2.0km/h的速度行驶时，振动轮与水稳料产生“同步振动”，使骨料重新排列，空隙率降低至15%以下。而终压阶段的静碾，则如同“定型锤”，将密实度锁定在98%以上。
This "resonance" effect is particularly critical during the re compression stage. When the roller travels at a speed of 1.5-2.0km/h, the vibrating wheel and the water stabilized material produce "synchronous vibration", causing the aggregate to rearrange and the void ratio to decrease to below 15%. The static rolling in the final pressing stage is like a "setting hammer", locking the compactness above 98%.
第三重匹配：行驶速度与压实遍数的“黄金比例”
Third Matching: The "Golden Ratio" between Driving Speed and Compaction Times
压路机的行驶速度与压实遍数，存在一个“黄金比例”。初压速度需控制在1.5km/h以内，确保水稳料初步稳定；复压阶段可提升至2.5km/h，但每遍压实需重叠30cm轮宽，形成“碾压带”；终压速度则回落至2.0km/h，以消除表面轮迹。
There is a "golden ratio" between the driving speed of a road roller and the number of compaction passes. The initial pressing speed should be controlled within 1.5km/h to ensure the initial stability of the water stable material; During the compaction stage, the speed can be increased to 2.5km/h, but each compaction layer needs to overlap the wheel width by 30cm to form a "rolling belt"; The final pressure speed will drop back to 2.0km/h to eliminate surface wheel marks.
更精细的管控涉及“时间窗口”。水稳料从摊铺到终压的时间需控制在2小时内，否则水泥初凝将导致压实度下降。这种“速度与时间的博弈”，要求压路机操作手兼具经验与精准度。
More precise control involves a 'time window'. The time from spreading to final compaction of water stable materials should be controlled within 2 hours, otherwise the initial setting of cement will lead to a decrease in compaction degree. This' game of speed and time 'requires the roller operator to have both experience and precision.
第四重匹配：含水量与压路机操作的“湿度平衡”
Fourth Matching: Moisture Balance between Moisture Content and Roller Operation
水稳料的含水量（通常比最佳含水量高0.5%-1%）是压实质量的“隐形指挥棒”。含水量过高时，压路机需降低振幅并减少遍数，防止“弹簧土”现象；含水量过低时，则需在复压前补水，再通过轮胎压路机的揉搓促进水分均匀分布。
The moisture content of water stable materials (usually 0.5% -1% higher than the optimal moisture content) is the "invisible conductor" of compaction quality. When the moisture content is too high, the roller needs to reduce the amplitude and the number of passes to prevent the phenomenon of "spring soil"; When the moisture content is too low, it is necessary to replenish water before re pressing, and then promote even distribution of moisture through the rolling of the tire roller.
这种“湿度平衡”在高温干燥环境中尤为挑战。此时需采用“雾状补水”技术，将水雾化至50微米粒径，避免局部积水导致离析。
This' humidity balance 'is particularly challenging in high-temperature and dry environments. At this time, the "mist like water replenishment" technology should be used to atomize the water to a particle size of 50 microns to avoid local water accumulation and segregation.
第五重匹配：压路机维护与压实质量的“长期契约”
Fifth Matching: Long term Contract for Roller Maintenance and Compaction Quality
压路机的维护状态，是压实质量的“隐性保障”。振动轴承的径向间隙需控制在0.1mm以内，否则将导致振幅衰减；轮胎压路机的胎压需保持恒定（误差≤2%），否则将影响揉搓效果。
The maintenance status of the road roller is the "implicit guarantee" of compaction quality. The radial clearance of the vibration bearing should be controlled within 0.1mm, otherwise it will cause amplitude attenuation; The tire pressure of the tire roller should be kept constant (error ≤ 2%), otherwise it will affect the kneading effect.
更关键的是“压路机-水稳料”的适应性磨合。新购压路机需经过50小时的“走合期”，在此期间避免高强度作业，使机械部件与材料特性逐步匹配。
More importantly, the adaptive running in of the "roller water stabilized material" is crucial. The newly purchased roller needs to go through a 50 hour "running in period" to avoid high-intensity operations and gradually match the mechanical components with the material properties.
压实是材料与机械的“双人舞”
Compaction is the 'duet' of materials and machinery
水稳料对压路机的要求，本质是对施工系统的深度理解。它要求从业者兼具材料学家的严谨与机械师的敏锐，在参数匹配与操作细节中构建起质量、效率与耐久性的平衡。当压路机与水稳料形成“默契共振”时，我们看到的，是道路施工从“经验驱动”向“科学管控”的进化。这种进化，无关未来想象，而是对当下标准的极致追求。
The requirements of water stable materials for rollers are essentially a deep understanding of the construction system. It requires practitioners to combine the rigor of materials scientists with the sensitivity of mechanics, and to establish a balance between quality, efficiency, and durability in parameter matching and operational details. When the roller and water stabilized material form a "tacit resonance", what we see is the evolution of road construction from "experience driven" to "scientific control". This evolution is not about imagining the future, but about the ultimate pursuit of current standards.
