Description
Technical field
The present invention relates to pavement patching, be specifically related to the material that a kind of pavement patching is used.
Background technology
The maintenance of road is one of important topic of current road engineering field face.According to statistics, in recent years, the annual funds that are used for the highway maintenance maintenance of China just surpass 30,000,000,000 yuan, perfect gradually along with the highway in China transportation network, and the maintenance of highway more and more comes into one's own.The features such as intensity is high, supporting capacity is strong owing to having, applied widely, abundant raw materials, good endurance, cement concrete pavement occupies critical role always in the construction of highway in China net, be a kind of very important pavement structure form.But, under As-Is, cement concrete pavement does not often reach desired value work-ing life, a lot of entity project are open to traffic and still only have several years, the crack just occurs, come to nothing, the disease such as disconnected plate, need to take grouting, rubblization to dispose, change plate or overlay that the technique means such as cover are recovered its structural-load-carrying capacity or the road table uses function.In addition, traditional repair mode not only long in time limit, traffic is disturbed large, costly, and the reparation means are only effective for certain concrete disease form, and helpless when other disease forms are repaired.Therefore, the patching material of developing for the various Major Diseases of cement concrete pavement can be repaired fast and effect is lasting has very important realistic meaning.
The patching material of cement concrete cracks is generally flexible materials, as polyvinyl chloride (PVC) cement, pitch, rubber etc.These materials only can reach the effect in shutoff crack, thus can not supporting crack two walls can not be jointly stressed with the both sides road deck as a whole, so can cause the crack diffusion and enlarge when vehicle fracture two walls have pressure; In addition, because contraction, the swelling property of these materials and cement concrete material differs greatly, cause easily be extruded its summer, the material that is extruded comes off from the original place under the effect of wheel, thereby when the cold weather concrete panel shrinks, the place, crack produces the seam sealer inefficacy of larger space; And, due to flexible patching material and the cement concrete pavement colour contrast large, the perfusion after forms black line on the road surface, comparatively seriously affect the use properties on road surface.
Top layer class disease for cement concrete pavement, the traditional method of highway maintenance department is to adopt asphalt to carry out the part to it to repair or whole cover, although it is comparatively easy to construct, but because the rigidity of bi-material is inconsistent, the existence of the shearing between the interface easily causes coming off of patching material and lost efficacy.Another kind of traditional method for repairing and mending is that the concrete of breakage is removed, again making is not less than the normal concrete of original design strength grade, mainly there is following problem in this repair mode: (1) novel concrete shrinks than old concrete and shrinks greatly, easily causes shrinkage cracking; (2) between new-old concrete due to reasons such as boundary defects, its mutual cohesive strength is low, all easily causes repair losing efficacy; (3) curing cycle long, bring larger pressure to traffic operation.
For the obvious defective of above-mentioned conventional repair material, in recent years, domesticly in succession develop various polymer concretes, polymer modification concrete, mix Fresh Concrete with Admixtures, the quick patching material for cement concrete pavement such as fibrous concrete and fast hard class cement, below introduce respectively the present Research of several patching materials.
Polymer concrete, polymer modification concrete, fibrous concrete, mix the fast repairing materials such as Fresh Concrete with Admixtures and fast hard class cement and be applicable to mainly that plate is repaired and cover is repaired, use range has significant limitation, and the usage quantitys such as polymkeric substance, fiber and admixture are large, price is more expensive has limited again its development and use.
Above-mentioned description about the Cement Concrete Pavement Reconstruction present condition of material shows, existing various types of materials for Cement Concrete Pavement Maintenance and maintenance all exist separately defective and the restriction of use range.
