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 in-situ cold recycled base construction technology in large and medium maintenance of asphalt pavement greatly saves repair costs.

工期縮短

Shorten the 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(shí)也能有效的提高施工區(qū)域內(nèi)行車(chē)水平。這一施工工藝相比原來(lái)的施工工藝來(lái)說(shuō)更加的簡(jiǎn)便，同時(shí)也可以在施工過(guò)程中開(kāi)放交通，保證道路的暢通，不會(huì)造成交通擁堵現(xiàn)象。

The use of full depth on-site cold recycling 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 can also open up traffic during the construction process, ensuring smooth road flow and avoiding traffic congestion.

節(jié)約資源

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(jìn)對(duì)環(huán)境的保護(hù)。它在施工過(guò)程中能夠?qū)⒃驹跒r青路面建設(shè)中使用過(guò)的材料進(jìn)行二次回收利用，特別是一些砂石材料，避免了再次開(kāi)采這類(lèi)資源，造成浪費(fèi)。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 of re mining 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.

提高路面的平整度

Improve the smoothness of the road surface

在瀝青路面修復(fù)過(guò)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(shí)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。

In the process of repairing asphalt pavement, the use of the full depth on-site cold recycling base construction process 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.

冷再生基層施工工藝能夠復(fù)原

The construction process of cold recycled base can be restored

冷再生基層施工工藝適用于修復(fù)大面積道路損毀，當(dāng)采用這一施工工藝進(jìn)行修復(fù)后，路面的使用性能與原先完整的路面無(wú)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 process is suitable for repairing large-scale road damage. After using this construction process for repair, the performance of the road surface is no different from the original complete road surface, and the newly laid road surface basically conforms to the original road surface performance.

全深式就地冷再生施工工藝與質(zhì)量控制措施

Construction technology and quality control measures for full depth on-site cold regeneration

全深式就地冷再生施工工藝原理

Principle of fully deep on-site cold regeneration construction process

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(jìn)行粉碎與攪拌融合在一起，以此來(lái)提供升級(jí)的均勻基層材料的維修技術(shù)。若舊材料中沒(méi)有足夠的力學(xué)性能與結(jié)構(gòu)強(qiáng)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(shí)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(lái)達(dá)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 upgraded and uniform base material maintenance technology. If the old material does not have sufficient mechanical properties and structural strength to carry the expected load, then new aggregates need to be added to it, and a certain proportion of chemical stabilizers need to be added to achieve the expected effect.
