全深式就地冷再生施工工藝主要采用就地冷再生施工設(shè)備對需要修復(fù)的破損瀝青路面進行冷銑刨、破碎以及篩選，再按比例加入新集料、再生結(jié)合料、水泥、石灰、水等，經(jīng)過常溫攪拌后，把這些物料鋪設(shè)路面上，再經(jīng)碾壓后成型。這一施工工藝是需要一整套工序在現(xiàn)場有序的完成。其中全深式就地冷再生包含著瀝青材料層與非瀝青材料層。

The full depth on-site cold recycling construction technology mainly uses on-site cold recycling construction equipment to perform cold milling, crushing, and screening on the damaged asphalt pavement that needs to be repaired. Then, new aggregates, recycled binders, cement, lime, water, etc. are added in proportion. After being stirred at room temperature, these materials are laid on the pavement and rolled to form. This construction process requires a complete set of procedures to be completed in an orderly manner on site. The full depth on-site cold regeneration includes both asphalt material layer and non asphalt material layer.

瀝青路面再生技術(shù)的優(yōu)勢

The advantages of asphalt pavement regeneration technology

(1)節(jié)約成本

(1) Cost savings

在瀝青路面的大、中修中使用全深式就地冷再生基層施工工藝與傳統(tǒng)的修整瀝青路面相比，極大的節(jié)約了修整成本。

Compared with traditional asphalt pavement repair, the use of full depth on-site cold recycling base construction technology in large and medium maintenance of asphalt pavement greatly saves repair costs.

(2)工期縮短

(2) Shortened construction period

在瀝青路面中使用全深式就地冷再生基層施工工藝能夠有效的縮短施工工期，盡快使得維修好的瀝青路面投入到使用中，同時也能有效的提高施工區(qū)域內(nèi)行車水平。這一施工工藝相比原來的施工工藝來說更加的簡便，同時也可以在施工過程中開放交通，保證道路的暢通，不會造成交通擁堵現(xiàn)象。

The use of full depth on-site cold recycled base construction technology in asphalt pavement can effectively shorten the construction period, quickly put the repaired asphalt pavement into use, and also effectively improve the safety driving level in the construction area. This construction process is more simple and efficient compared to the original construction process, and it can also open up traffic during the construction process, ensuring smooth road traffic and avoiding traffic congestion.

(3)節(jié)約資源

(3) Save resources

在全深式就地冷再生基層施工工藝中能夠有效的節(jié)約資源，促進對環(huán)境的保護。它在施工過程中能夠?qū)⒃驹跒r青路面建設(shè)中使用過的材料進行二次回收利用，特別是一些砂石材料，避免了再次開采這類資源，造成浪費。在回收利用這一系列材料中也能夠避免這些材料被廢棄占用土地資源，造成環(huán)境污染。

In the construction process of fully deep on-site cold recycling base layer, it can effectively save resources and promote environmental protection. It can recycle and reuse the materials originally used in asphalt pavement construction, especially some sand and gravel materials, during the construction process, avoiding the waste caused by the re exploitation of such resources. In the recycling and utilization of this series of materials, it is also possible to avoid these materials being abandoned and occupying land resources, causing environmental pollution.

(4)提高路面的平整度

(4) Improve the smoothness of the road surface

在瀝青路面修復(fù)過程中采用全深式就地冷再生基層施工工藝能夠有效的保留現(xiàn)有道路的完整性結(jié)構(gòu)與凈空，同時還能夠有效的糾正路面縱斷面以及橫坡現(xiàn)象，極大的提高了路面的平整度。

The use of full depth on-site cold regeneration base construction technology in the process of asphalt pavement repair can effectively preserve the integrity structure and clearance of the existing road, while also effectively correcting the longitudinal and transverse slope phenomena of the road surface, greatly improving the smoothness of the road surface.

(5)冷再生基層施工工藝能夠復(fù)原

(5) Cold recycled base construction technology can restore

冷再生基層施工工藝適用于修復(fù)大面積道路損毀，當采用這一施工工藝進行修復(fù)后，路面的使用性能與原先完整的路面無差別，新鋪設(shè)的路面基本符合原本的路面性能。

The cold recycled base construction technology is suitable for repairing large-scale road damage. When this construction technology is used for repair, the performance of the road surface is no different from the original complete road surface, and the newly laid road surface basically meets the original road performance.

全深式就地冷再生施工工藝與質(zhì)量控制措施

Full depth on-site cold regeneration construction technology and quality control measures

(1)全深式就地冷再生施工工藝原理

(1) The principle of fully deep on-site cold regeneration construction technology

全深式就地冷再生施工工藝需要將瀝青路面中全部厚度的瀝青面層與預(yù)定比例匯總的下臥層統(tǒng)一進行粉碎與攪拌融合在一起，以此來提供升級的均勻基層材料的維修技術(shù)。若舊材料中沒有足夠的力學(xué)性能與結(jié)構(gòu)強度承載預(yù)期中的荷載，那么就需要在其中加入新的集料，同時也需要按照一定的比例加入定量的化學(xué)穩(wěn)定劑，以此來達到預(yù)期的效果。

The full depth on-site cold recycling construction process requires the crushing and mixing of the entire thickness of the asphalt surface layer in the asphalt pavement and the predetermined proportion of the underlying layer, in order to provide an upgraded and uniform maintenance technology for the base material. If the old material does not have sufficient mechanical properties and structural strength to bear the expected load, it is necessary to add new aggregates and a certain proportion of chemical stabilizers to achieve the expected effect.
