简单几招快速辨别沥青冷补料的好坏
来源:/ 日期:2022-08-26
层出不穷的不完整工艺生产出来的沥青冷补料,让人选择不出来,而且选择好的冷补料,让修补效果事半功倍。咱们拿到沥青冷补料,自己就能快速辨别好的冷补料的几个方法,济南沥青料人员为您解答!
The asphalt cold patching materials produced by endless incomplete processes are difficult to select, and the good cold patching materials can make the repair effect twice the result with half the effort. When we get the asphalt cold patching material, we can quickly identify several methods of good cold patching material. Jinan asphalt personnel will answer for you!
1、色泽乌黑发亮
1. Color: dark and shiny
沥青冷补料一般选用70#或者90#石油沥青配置母液,因此,咱们拿到的冷补料发黑、发亮,比较有光泽。
Generally, 70 # or 90 # petroleum asphalt is used as the cold patching asphalt to prepare the mother liquor. Therefore, the cold patching materials we get are black, shiny and shiny.
2、松散度适宜
2. Suitable looseness
松散度适宜,不松散、凝聚结块。
The degree of looseness is appropriate, without looseness and agglomeration.
沥青冷补料可以长时间常温存储和常温施工,还要具备很好的粘聚性,因此,无论放几个月,咱们打开冷补料包装,一方面看到的材料应该是无明显的凝聚结块现象,且能用铁铲方便地拌和操作,和易性好;另一方面又不能太松散,集料之间应该是相互粘连,抓一把攥紧松开后,集料会缓慢分离,仔细看还能看到拉丝现象发生。
Asphalt cold patching material can be stored and constructed at room temperature for a long time, and also has good cohesiveness. Therefore, no matter how many months we put it, when we open the cold patching material package, on the one hand, the material should be free of obvious agglomeration, and can be easily mixed and operated with a shovel, with good workability; On the other hand, the aggregates should not be too loose. The aggregates should adhere to each other. After grasping and loosening, the aggregates will be separated slowly. If you look carefully, you can see the occurrence of wire drawing.
3、不漏石料不泛油
3. No stone leakage, no oil flashing
专用设备生产的冷补料,具有合适的油石比,因此,一方面不会出现石料裹敷不好裸露的现象,另一方面,包裹过冷补料的纸巾,纸巾上会有石粒轮廓印记,不会出现成块的油浸现象。
The cold patching material produced by the special equipment has a proper oil stone ratio. Therefore, on the one hand, there will be no exposure of the stone material, and on the other hand, the paper towel wrapped with the supercooled patching material will have a stone particle outline mark on the paper towel, and there will be no oil immersion in the block.
4、水泡不脱落
4. Blister does not fall off
冷补料有良好的耐水性,混合料按水煮法或水浸法检验的抗水剥落性能(裹覆面积)不得小于95%,常规操作可以小块压实后泡入常温纯净水中24小时,无松散坍塌现象。
The cold patching material has good water resistance. The water peeling resistance (covering area) of the mixture tested by the water boiling method or the water immersion method shall not be less than 95%. The conventional operation can be carried out by immersing small pieces of compacted material into the pure water at room temperature for 24 hours, without looseness and collapse.
5、集料粗细搭配适宜
5. The thickness and fineness of aggregate are appropriate
集料粗细搭配适宜,拒绝见不到细料或细料比例超过80%的材料。冷补料的终末强度要能达到与热拌沥青混合料相当甚更好,须选用级配石料。
The coarse and fine aggregate shall be properly matched, and the materials with no fine aggregate or the proportion of fine aggregate exceeding 80% shall be rejected. The final strength of cold patching material shall be equal to or even better than that of hot mixed asphalt mixture, and graded stone shall be selected.
In the process of pavement repair, although the construction speed is fast and the technical requirements for equipment and personnel are not high, the effect after repair is comparable to that of hot mixed asphalt mixture in terms of color, stability and service life of the pavement after repair.
