3、路沿石接缝处错位不超过1mm；侧石和平石必须在中间均匀错缝。

3. The misalignment at the joint of the curbstone shall not exceed 1mm; The side stones and flat stones must be evenly staggered in the middle.

4、路沿石侧平石应保证尺寸和光洁度满足设计要族亮求。外观美观，对弯道部猜圆分侧石应按设计半径专门加工弯道石，砌筑时保兆兆宽证线形流畅、圆顺、拼缝紧密。弧形侧石必须人工精凿后抛光处理。

4. The flat stones on the roadside should ensure that their size and smoothness meet the design requirements. The appearance is beautiful, and the side stones of the curved section should be specially processed according to the design radius. During masonry, it should be ensured that the line shape is smooth, round, and the joints are tight. The curved side stones must be manually chiseled and polished.
