簡單幾招快速辨別瀝青冷補料的好壞

來源：http://shyy66.com/ 日期：2022-08-26

層出不窮的不完整工藝生產(chǎn)出來的瀝青冷補料，讓人選擇不出來，而且選擇好的冷補料，讓修補效果事半功倍。咱們拿到瀝青冷補料，自己就能快速辨別好的冷補料的幾個方法，濟南瀝青料人員為您解答！

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、色澤烏黑發(fā)亮

1. Color: dark and shiny

瀝青冷補料一般選用70#或者90#石油瀝青配置母液，因此，咱們拿到的冷補料發(fā)黑、發(fā)亮，比較有光澤。

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、松散度適宜

2. Suitable looseness

松散度適宜，不松散、凝聚結(jié)塊。

The degree of looseness is appropriate, without looseness and agglomeration.

瀝青冷補料可以長時間常溫存儲和常溫施工，還要具備很好的粘聚性，因此，無論放幾個月，咱們打開冷補料包裝，一方面看到的材料應該是無明顯的凝聚結(jié)塊現(xiàn)象，且能用鐵鏟方便地拌和操作，和易性好；另一方面又不能太松散，集料之間應該是相互粘連，抓一把攥緊松開后，集料會緩慢分離，仔細看還能看到拉絲現(xiàn)象發(fā)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

專用設備生產(chǎn)的冷補料，具有合適的油石比，因此，一方面不會出現(xiàn)石料裹敷不好裸露的現(xiàn)象，另一方面，包裹過冷補料的紙巾，紙巾上會有石粒輪廓印記，不會出現(xiàn)成塊的油浸現(xiàn)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、水泡不脫落

4. Blister does not fall off

冷補料有良好的耐水性，混合料按水煮法或水浸法檢驗的抗水剝落性能（裹覆面積）不得小于95%，常規(guī)操作可以小塊壓實后泡入常溫純凈水中24小時，無松散坍塌現(xiàn)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、集料粗細搭配適宜

5. The thickness and fineness of aggregate are appropriate

集料粗細搭配適宜，拒絕見不到細料或細料比例超過80%的材料。冷補料的終末強度要能達到與熱拌瀝青混合料相當甚至更好，須選用級配石料。

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.

在路面修補過程中，雖然施工速度快、對設備和人員技術要求不高，但修補后的效果與熱拌瀝青混合料相比，無論是顏色、穩(wěn)定度，還是修補后的路面使用壽命，都是相當?shù)?。關注我們，了解http://shyy66.comhttp://shyy66.com更多！

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.
