Description
Technical field
The present invention relates to concrete patching technical fields, more particularly, to a kind of reparation of Old cement concrete
Remodeling method.
Background technique
Cement concrete, which refers to, forms whole engineered composite material by cement, sand, the mixing of Shi Dengyong water, usually uses water
Mud makees cementitious material, and sand, masonry gather materials, and cooperates by a certain percentage with water (adding or be not added additive and admixture), it is agitated, at
Type, oxidation and obtain.Cement concrete pavement refers to the road surface that surface layer is done using cement concrete as main material, is high grade pavement
One of primary structure form, be widely adopted in highways at different levels.Cement concrete pavement big, bearing capacity with rigidity
By force, the advantages that fatigue life is long, water-fast, high temperature resistant, durability is good, material source is extensive, good economy performance, the high speed in China are public
In road and urban road, cement concrete pavement occupies very big specific gravity.
With the increase of traffic volume of highway, road surface over burdening situation increases and the quickening of running speed, and most of cement is mixed
Solidifying soil surface in use, can generate crack and different degrees of breakage, influence the flatness and driving on road surface
Comfort；If carrying out pavement patching not in time, rolling repeatedly for vehicle can be such that situation gets worse, fracture development or damaged shape
It at recess, influences traffic safety and traffic accident even occurs, make subgrade settlement finally to scrap whole section of highway pavement.Cause
This, the crack of cement concrete pavement and breakage needs are repaired in time.Due to cost considerations, conventional method for repairing and mending
It is to remove damaged concrete, is repaired with normal concrete identical or high grade as the design grade on former road surface, but
Novel concrete is shunk greatly, shrinkage cracking occurs after easily leading to repairing；Normal concrete adhesion strength is low, at new-old concrete interface
To there is engaging portion cracking；Curing period, is long, and the time of open to traffic is long.
Summary of the invention
