道路維護(hù)部門在修補(bǔ)路面時(shí)通常都會(huì)使用熱攪拌瀝青混合料，但是由于熱料修補(bǔ)受到天氣、溫度、坑槽大小、數(shù)量、損壞程度等因素的影響，對(duì)隨時(shí)出現(xiàn)的坑槽尤其是冬季坑槽，不能及時(shí)修補(bǔ)，必將造成損壞加劇，不但浪費(fèi)修補(bǔ)材料，甚至影響交通安全和降低道路使用壽命。

The road maintenance department usually uses hot mix asphalt mixture when repairing road surfaces. However, due to the influence of factors such as weather, temperature, pit size, quantity, and degree of damage on hot mix repair, if pits, especially winter pits, that appear at any time, cannot be repaired in a timely manner, it will inevitably exacerbate the damage, not only waste repair materials, but also affect traffic safety and reduce the service life of the road.

瀝青冷補(bǔ)料采用特殊的方法改質(zhì)瀝青，使得瀝青具有優(yōu)秀的粘結(jié)性、感壓性和粘彈性，在適當(dāng)壓實(shí)之后，能夠長(zhǎng)久的粘在修補(bǔ)處不脫落。瀝青冷補(bǔ)料以其可以在全天候條件下修補(bǔ)路面，操作簡(jiǎn)便，修補(bǔ)質(zhì)量好，存放長(zhǎng)久，節(jié)省費(fèi)用等諸多優(yōu)點(diǎn)，已經(jīng)被廣泛的應(yīng)用于各省市道路路面修補(bǔ)，且日益受到道路養(yǎng)護(hù)部門的認(rèn)可和歡迎。

Asphalt cold repair materials use special methods to modify asphalt, making it have excellent adhesion, pressure sensitivity, and viscoelasticity. After appropriate compaction, it can stick to the repair area for a long time without falling off. Asphalt cold repair materials have many advantages, such as being able to repair road surfaces under all weather conditions, easy to operate, good repair quality, long-term storage, and cost saving. They have been widely used in road surface repair in various provinces and cities, and are increasingly recognized and welcomed by road maintenance departments.

瀝青冷料施工工藝

Asphalt cold material construction technology

⒈清理坑穴：一般修補(bǔ)應(yīng)將待修補(bǔ)的坑穴內(nèi)及四周的碎石、廢渣清理干凈，坑穴內(nèi)不得存有泥漿、冰塊等雜物。高速公路、市政掘路工程的修補(bǔ)，被修補(bǔ)的洞穴、溝槽應(yīng)有整齊的切邊，廢渣的清除要見(jiàn)到固體堅(jiān)固面為止。

1. Cleaning of pits: Generally, for repairs, the gravel and waste residue inside and around the pit to be repaired should be cleaned thoroughly, and there should be no mud, ice or other debris inside the pit. The repair of highways and municipal road excavation projects should have neat cut edges for the repaired caves and trenches, and the removal of waste should be done until a solid and sturdy surface is visible.

⒉填滿坑穴：把足夠的冷補(bǔ)材料填進(jìn)坑穴內(nèi)，知道填料高出地面1.5cm左右，高速公路和一般公路修補(bǔ)，其材料的投入量可增加20％或10％左右。填滿后坑穴中央處應(yīng)高于四周路面并呈弧形。如路面坑穴破損深度在5cm以上時(shí)，填補(bǔ)工作應(yīng)以每3－5cm為一層，分層填補(bǔ)、逐層壓實(shí)。

2. Fill the pit: Fill enough cold filling material into the pit until the filling material is about 1.5cm above the ground. For repairing highways and general highways, the amount of material input can be increased by about 20% or 10%. After filling, the center of the pit should be higher than the surrounding road surface and be curved. When the depth of road surface potholes is more than 5cm, the filling work should be done in layers of 3-5 cm, with each layer filled and compacted layer by layer.

⒊壓實(shí)：鋪設(shè)均勻后，根據(jù)實(shí)地修補(bǔ)環(huán)境、修補(bǔ)面積大小和深度，選車適當(dāng)?shù)膲簩?shí)工具和方法進(jìn)行壓實(shí)。如：人工用鏟背、人力夯、震動(dòng)平板夯、平底鋁壓板、貨車輪胎、壓路機(jī)或攤鋪機(jī)等壓實(shí)方式。

3. Compaction: After laying evenly, select appropriate compaction tools and methods based on the on-site repair environment, repair area size, and depth for compaction. For example, manual backhoes, manual compactors, vibrating flat compactors, flat bottomed aluminum pressure plates, truck tires, road rollers or pavers, and other compaction methods are used.

瀝青冷補(bǔ)料的特點(diǎn)

The characteristics of asphalt cold repair materials

1、全天候型修補(bǔ)材料: 瀝青冷補(bǔ)料適用的環(huán)境溫度范圍寬，可在-30℃至50℃之間適用，無(wú)論雨天、雨雪或晴天均可施工

1. All weather repair material: Asphalt cold repair material is suitable for a wide range of ambient temperatures, ranging from -30 ℃ to 50 ℃, and can be used for construction on rainy, snowy, or sunny days

2、施工簡(jiǎn)單: 使用瀝青冷補(bǔ)料進(jìn)行路面坑槽修補(bǔ)時(shí)無(wú)需粘層油．備料可隨用隨取，不需要重型施工機(jī)械，可根據(jù)路面的不同修補(bǔ)情況采用沖擊壓實(shí)、人工壓實(shí)或汽車輪胎碾壓即可。并且用瀝青冷補(bǔ)料修補(bǔ)過(guò)的區(qū)域無(wú)需封閉交通，可立即通車，大大緩解因道路修補(bǔ)施工而造成的交通壓力。

2. Simple construction: When using asphalt cold patching material for repairing road potholes, there is no need for adhesive oil. The material can be prepared and taken at any time, without the need for heavy construction machinery. Depending on the different repair conditions of the road surface, impact compaction, manual compaction, or car tire rolling can be used. And the area repaired with asphalt cold repair material does not need to close traffic and can be immediately opened to traffic, greatly alleviating the traffic pressure caused by road repair construction.

3、修補(bǔ)質(zhì)量佳 : 瀝青冷補(bǔ)料具有極強(qiáng)的抗老化和粘結(jié)性能，修補(bǔ)后的坑穴，不易產(chǎn)生脫落、龜裂等不良現(xiàn)象，不需重復(fù)修補(bǔ)。

3. Good repair quality: the asphalt cold patching material has extremely strong anti-aging and bonding properties, and the pits after repair are not easy to fall off, crack and other undesirable phenomena, so there is no need to repeat the repair.

4、修補(bǔ)成本低 : 使用瀝青冷補(bǔ)料施工時(shí)，不受天氣和坑穴大小及數(shù)量的限制，且修補(bǔ)時(shí)無(wú)需加熱或攪拌，可根據(jù)實(shí)際用量隨時(shí)取用，剩余材料可在下次修補(bǔ)中繼續(xù)使用，不會(huì)造成材料浪費(fèi)．真正地100％利用。

4. Low repair cost: When using asphalt cold repair material for construction, it is not limited by weather and pit size and quantity, and there is no need to heat or mix during repair. It can be used at any time according to the actual amount, and the remaining materials can continue to be used in the next repair without causing material waste. It is truly 100% utilized.

5、綠色環(huán)保: 瀝青冷補(bǔ)料生產(chǎn)和使用過(guò)程中不會(huì)產(chǎn)生粉塵和黑煙，且成品不溶于水，因而不會(huì)污染大氣和地下水，有利于環(huán)境保護(hù)。

5. Green and environmentally friendly: During the production and use of asphalt cold repair materials, no dust or black smoke is generated, and the finished product is insoluble in water, so it will not pollute the atmosphere and groundwater, which is beneficial for environmental protection.

6、易于保存: 常溫下袋裝密封成品可存放達(dá)兩年之久，不會(huì)結(jié)塊。

6. Easy to store: Sealed finished products in bags can be stored for up to two years at room temperature without clumping.
