什么是冷再生材料成形?

冷再生材料成形
Cold recycling material forming
冷再生材料的性質(zhì)與傳統(tǒng)道路材料不完全相同,因而對成形的要求也不完全相同。冷再生材料按再生劑大致可以區(qū)分為兩類:
The properties of cold recycled materials are not the same as those of traditional road materials, so the forming requirements are not the same. Cold recycled materials can be roughly divided into two types according to regenerants
無機再生劑和瀝青再生劑,瀝青再生時往往加入少量水泥以提高其抗水損壞能力。較常用的無機再生劑是水泥,其他還有二灰、水泥粉煤灰等。
Inorganic regenerant and asphalt regenerant, when asphalt is recycled, a small amount of cement is often added to improve its water damage resistance. The more commonly used inorganic regenerant is cement, and the others are lime fly ash, cement fly ash, etc.
無機穩(wěn)定冷再生一般按照傳統(tǒng)的半剛性材料進行成形和養(yǎng)生。常溫下進行重型擊實試驗或者振動擊實試驗,在20℃或者25℃下養(yǎng)生7天。
Inorganic stable cold recycling is generally formed and cured according to traditional semi-rigid materials. Heavy compaction test or vibration compaction test shall be conducted at room temperature, and curing at 20 ℃ or 25 ℃ for 7 days.
通過含水量-強度關(guān)系確定其含水量。瀝青穩(wěn)定劑冷再生時的情況比較復(fù)雜,尚無統(tǒng)一方法。
The water content was determined by the relationship between water content and strength. The situation of cold recycling of asphalt stabilizer is complex, and there is no unified method.
冷再生材料組成設(shè)計方法常見的方法是用擊實法確定液體量,用馬歇爾穩(wěn)定度、干劈裂強度、濕劈裂強度中的一個或幾個達到優(yōu)來確定瀝青用量。
The common method of composition design of cold recycled materials is to determine the amount of liquid by compaction, and determine the amount of asphalt by one or more of Marshall stability, dry splitting strength and wet splitting strength.

冷再生路面結(jié)構(gòu)
Cold recycling pavement structure
國外的冷再生基本結(jié)構(gòu)是:熱拌瀝青混合料層+冷再生層+舊有基層。舊有基層一般是砂礫基層。
The basic structure of cold recycling abroad is: hot mix asphalt mixture layer + cold recycling layer + old base. The old base is generally gravel base.
目前國內(nèi)的冷再生道路其中使用較多的結(jié)構(gòu)有熱拌瀝青混合料層+再生層+半剛性層和熱拌瀝青混合料層+再生層。
At present, the most commonly used structures of domestic cold recycling roads are hot mix asphalt mixture layer + recycling layer + semi-rigid layer and hot mix asphalt mixture layer + recycling layer.
隨著我國大量的路面進入維修期,路面冷再生技術(shù)會得到更廣泛的使用。文章總結(jié)了國內(nèi)外再生的技術(shù)要點。
With a large number of pavements entering the maintenance period in China, the cold recycling technology will be more widely used. This paper summarizes the main points of regeneration technology at home and abroad.
國內(nèi)對冷再生前評價尚無專門的評價方法,需要進一步研究;冷再生材料開始一般作為基層使用,目前逐步作為下面層使用;
There is no special evaluation method for pre cold recycling evaluation in China, which needs further study;
在我國冷再生施工中,水泥作為再生劑較多其實驗方法已經(jīng)較為統(tǒng)一,主要的參考傳統(tǒng)的半剛性材料;而瀝青作為再生劑的冷再生實驗方法還不統(tǒng)一,需要進一步研究確定合理的實驗方法。
In the construction of cold recycling in our country, there are many cement as recycling agent, and its experimental method has been more unified, mainly referring to the traditional semi-rigid materials; while the experimental method of asphalt as recycling agent is not unified, so it needs further research to determine the reasonable experimental method.
