Description
Technical field
The present invention relates to road construction methods.It is more particularly related to which a kind of base cures cold regeneration construction side
Method.
Background technology
The highway in China passes through the fast development of more than ten years, when building highway and factory site is hardened, using large-scale machine
Toolization is constructed, and mainly with the central mix of material, dispersion transport, the freight volume of material is very big, with the development of soil-solidified-agent,
Various soil and solid waste material are more and more used for the construction of base's even steady layer of water, therefore detail design is based on taking on the spot
The principle that material and solid waste utilize, also more extensive to the use of curing agent, traditional central mix is at stirring intensity, interval
Between, uniformity coefficient etc. all cannot be satisfied curing agent requirement in use, while the development of cold renewal equipment, improves and makees on the spot
The efficiency of industry, shortens the activity duration, strengthens the ability of stirring, combines other heavy duty work equipment, has had been provided with and made on the spot
The basis of industry.
In addition mileage in highway open to traffic and density raising are very big in recent years in China, and the maintenance and upgrade of highway improves task and follows on sb.'s heels
And arrive.Traditional highway upgrading is main due to being restricted by machinery, technology, and much having the limitation of the passage headroom of viaduct
If overlaying new high intensity base and road surface on old pavement.This mode primary disadvantage is that, the structure sheaf intensity on old road
It is low also uneven, it can only be used as roadbed, waste some quality materials, new road elevation improves, width narrows, and increases road
Base and base's quantities waste land resource.
Since common cold in place recycling construction is that the face layer of original path and base are become new roadbase (or bottom
Base), cause the steady layer of water of new road at least to start making on the basis of this absolute altitude, moreover in the road reformation of high standard
In, sometimes using regeneration zone as underlayment, the base materials such as two-ash broken stones are also overlayed on this basis, this allows for being transformed
Grade elevation later is more than the absolute altitude on original road surface, and along road structure, the design structure on road surface will change therewith.Such as
Fruit is constructed in urban road using this method, and original drainage system will also be influenced by some therewith.Therefore, for road marking
Height has the section more strictly limited, needs to regenerate after excluding using old road part.
With the immediate patent of present inventive concept《It is a kind of to be cured as the construction method of road steady layer of water using the soil body》(Shen
Please number：CN201710180391.3) the invention discloses a kind of using soil body solidification as the implementation of road steady layer of water, with
It builds based on the soil that spoir is transported to obtained by construction site or the on the spot mechanical scarifying of soil, mixes soil-solidified-agent and cement system
It at solidified earth, paves onto roadbed, after roller-compaction health, the water stability for becoming alternative Traditional foundations layer is very outstanding
Base, underlayment.The road steady layer of water that this method is implemented is high with intensity, water stability is good, durability is good, frost resistance is strong, cost
Low advantage can shorten the construction period, ensure construction quality, improve road structure performance, improve roadbed water stability, and extending road makes
Use the service life；Solve the problems, such as that conventional method of high cost, high energy consumption, later period maintenance are costly etc.；The soil body has largely been used simultaneously,
Traditional foundations layer is effectively substituted, resources and energy consumption and environmental pollution are reduced, there is significant economic and social profit.But this
The content of a patent disclosure of description in to(for) mechanical execution is inadequate, and mechanical work is not retouched for cement or aggregate etc. first
It states, curing agent is using water spray operation, all it cannot be guaranteed that the uniform incorporation of cement and curing agent, can not ensure operating efficiency and work
Industry quality.
Invention content
