冷再生技术在旧路面处理方面的应用

来源:http://www.tclqgc.com/ 日期:2023-01-11 发布人:guanli
冷再生技术在原有公路实际情况基础上进行施工,不但对于原有路基没有影响,还有利于提高原公路等级,同时铺层厚度控制得更加准确。下面冷再生机出租厂家来讲讲冷再生技术在旧路面处理方面的应用!
The cold regeneration technology is constructed on the basis of the actual conditions of the original highway, which not only has no impact on the original subgrade, but also is conducive to improving the grade of the original highway, and at the same time, the layer thickness is controlled more accurately. Let's talk about the application of cold recycling technology in the treatment of old pavement!
在进行路面冷再生施工的过程中,先应按照设计方案要求的厚度刨除现有路面,铣刨机应保持匀速运行,速度控制在4—6m/min左右,铣刨完成的路面不得存在团结成块现象。
In the process of cold pavement regeneration construction, the existing pavement shall be planed according to the thickness required by the design scheme. The milling machine shall operate at a constant speed, and the speed shall be controlled at about 4-6 m/min. The milled pavement shall not be united into blocks.
旧有路面面层材料在破碎之后,应对其进行筛分,合理控制回收集料的尺寸与级配,避免存在过大粒径,并运送至指定拌合地点集中堆放。
After the old pavement surface material is broken, it should be screened, and the size and grading of recycled aggregate should be controlled reasonably to avoid excessive particle size, and transported to the designated mixing site for centralized stacking.
其次是修整下承层,将表面存在的杂物清除干净,调整路拱坡度,若存在坑洞、脱皮等现象,应及时进行处理,避免影响与再生结构层的粘结性能。待其质量验收合格之后,将乳化沥青透油层均匀撒布至下承层表面。
The second is to trim the lower bearing layer, remove the sundries on the surface, adjust the slope of the road arch, and timely deal with the potholes, peeling and other phenomena to avoid affecting the bonding performance with the recycled structural layer. After the quality acceptance, evenly spread the emulsified asphalt prime coat onto the surface of the lower bearing layer.

若原路面材料级配无法达到冷再生技术施工标准时,应当加入一定的新集料,所选取集料技术指标应符合相关技术规范。
If the gradation of raw pavement materials cannot meet the construction standard of cold recycling technology, a certain amount of new aggregate shall be added, and the selected aggregate technical indicators shall comply with relevant technical specifications.
为提升再生结构层早期强度,通常情况下再生混合料中应掺入适量水泥,宜采用初凝时间较长的水泥材料。在充分掌握各项原材料性能指标的基础上,通过多次试验确定佳配合比例,确保满足公路工程施工的要求。
In order to improve the early strength of the recycled structural layer, in general, the recycled mixture should be mixed with an appropriate amount of cement, and the cement material with a long initial setting time should be used. On the basis of fully mastering the performance indicators of various raw materials, the best mix proportion is determined through multiple tests to ensure that the requirements of highway engineering construction are met.
此外材料的选取和比例应该适当。施工方须根据整个路面的混凝土结构状况来界定佳材料混入比例,以达到大限度提升成型路面刚性的作用。例如在选取骨料时,应注意骨料好要大于5mm,在材料配比中至少要占到四成以上的重量。做到这一点才能保证成型路面的质量。
In addition, the selection and proportion of materials should be appropriate. The construction party shall define the mixing proportion of good materials according to the concrete structure of the whole pavement, so as to achieve the function of improving the rigidity of the formed pavement to a large extent. For example, when selecting aggregates, it should be noted that the quality of aggregates should be greater than 5mm, accounting for at least 40% of the weight in the material mix. Only by doing this can the quality of the formed pavement be guaranteed.
冷再生技术的不断改善可以很圆满的解决这些问题,在不禁止公路通行的前提下,完成道路的修整工作。更好的促进了经济的发展。更多相关内容,就来我们网站http://www.tclqgc.com进行咨询吧!
