Abstract
The utility model discloses a novel basalt fiber rib continuously-reinforced cement concrete composite pavement. The composite pavement comprises a graded broken stone layer, a cement stabilized graded broken stone layer, a fine-grained asphalt concrete layer, a continuously-reinforced cement concrete layer and a fine-grained modified asphalt concrete layer, all of which are arranged from bottom to top, wherein the continuously-reinforced cement concrete layer comprises basalt fiber ribs and concrete spread on the basalt fiber ribs, the parts, close to end portions, of the basalt fiber ribs are fixedly connected with reinforcements by virtue of steel strands, and the reinforcements are connected with ground anchor beams and Mauler joints. Compared with the traditional reinforcements, the novel basalt fiber rib continuously-reinforced cement concrete composite pavement has the advantages that the basalt fiber ribs are low in mass and high in strength, the mass of the basalt fiber rib is about 1/5 that of the common reinforcement, and the strength of the basalt fiber rib is more than 6 times greater than that of the common reinforcement; the basalt fiber ribs can be continuously produced in the longitudinal direction and can be arranged according to the length of a road segment if applied to the continuously-reinforced cement concrete pavement, and therefore, the longitudinal welding step of reinforcing is omitted and the progress of engineering construction is greatly improved.
Description
Technical field
The utility model relates to a kind of novel basalt fibre muscle continuous reinforcement cement concrete composite pavement.
Background technology
Continuous Reinforcement Cement Concrete Pavement can be born heavy traffic loading, solid, durable, is a kind of road structure form that can ensure Long Service Life, has its unique advantage, is one of important directions of modern road structure development.Longitudinally be furnished with the reinforcing bar of sufficient amount on road surface, object is to control the crack that Cement Concrete Pavement Slab longitudinal contraction produces.Therefore, in the time of construction, do not establish swollen, contracting seam completely, form a complete and smooth driving surface, eliminate the weak link of Portland cement concrete pavement, reduce the approach that disease occurs, strengthened the integral rigidity of road slab, improved the stationarity of running car.But there are following two hang-ups in Continuous Reinforcement Cement Concrete Pavement at present:
1, at present CRCP all to adopt reinforcing bar be arrangement of reinforcement muscle material, there is good mechanical property, but unavoidably there is the problem of corrosion in reinforcing bar, this will have a strong impact on the application life on road surface.And reinforcing bar in concrete is little on load stress impact, mainly works to control crack (axially loaded), therefore in road surface, wastes one's talent on a petty job in fact with so many reinforcing bar for having.
2, cement concrete pavement is not ideal enough at aspects such as road-ability, maintenance conveniences compared to asphalt concrete pavement.
Summary of the invention
Above-mentioned two hang-ups that exist in order to overcome existing Continuous Reinforcement Cement Concrete Pavement, the utility model provides a kind of novel basalt fibre muscle continuous reinforcement cement concrete composite pavement that can give full play to Continuous Reinforcement Cement Concrete Pavement and have again in the advantage aspect Heavy Traffic and durability of bearing the environment-friendly high-efficiency of asphalt concrete pavement driving advantage comfortable, easy to maintenance.
The technical solution adopted in the utility model is:
Novel basalt fibre muscle continuous reinforcement cement concrete composite pavement, it is characterized in that: be provided with from bottom to top graded broken stone layer, cement stabilized grading crushed stones layer, particulate formula asphalt concrete layer, continuous reinforcement cement concrete layer and particulate formula modified asphalt concrete layer, described continuous reinforcement cement concrete layer comprises basalt fibre muscle and spreads out and puts on the concrete on basalt fibre muscle, described basalt fibre muscle is fixedly connected with reinforcing bar by steel glue near the position of end, described reinforcing bar with ground anchor beam, hair strangle seam be connected.
Further, the thickness of described graded broken stone layer is 20～22cm, the thickness of described cement stabilized grading crushed stones layer is 18～20cm, the thickness of described particulate formula asphalt concrete layer is 4～6cm, the thickness of described continuous reinforcement cement concrete layer is 28～30cm, and the thickness of described particulate formula modified asphalt concrete layer is 6～10cm.
The utility model improves common Continuous Reinforcement Cement Concrete Pavement from road surface reinforcements and road structure two aspects.From road surface reinforcements, utilize basalt fibre muscle to substitute reinforcing bar the cement concrete pavement of most of length is carried out to continuous reinforcement.Still adopt reinforcing bar arrangement of reinforcement in the position near end, and use special steel glue and the fixing basalt fibre of basalt yarn binding and reinforcing bar, then rely on reinforcing bar to strangle seam with ground anchor beam, hair and be connected.From road structure, road structure form is to overlay asphaltic road-mix surface course on Continuous Reinforcement Cement Concrete Pavement.
The beneficial effects of the utility model are embodied in:
1 and traditional reinforcing bar contrast: basalt fibre muscle quality is light and intensity is high, and its quality is plain bars 1/5 left and right, and intensity is 6 times more than of plain bars;
2, basalt fibre muscle longitudinally can produced continuously, can be configured according to road section length for Continuous Reinforcement Cement Concrete Pavement, has reduced the longitudinal welding sequence of reinforcing bar arrangement of reinforcement, has greatly improved engineering construction progress;
3, basalt fibre is that lithotome refining forms, and the muscle material of its formation has reinforcing bar and the incomparable environment-friendly advantage of other fiber bar, belong to low carbon materials cheap, that raw material reserves are abundant, and rotproofness is better than reinforcing bar greatly;
4, the specific constructive form of surface layer is the composite structure that adds black top mixed layer on novel basalt fibre muscle cement concrete pavement joining continuously, this kind of composite construction can not only be given full play to and join continuously novel basalt fibre muscle cement concrete pavement in the huge advantage of bearing aspect heavier more complicated traffic loading and the anti-destruction of antidetonation, more can utilize traditional asphalt rigid pavement road-ability, maintenance convenient should etc. the advantage of aspect; This composite construction is to join continuously novel basalt fibre muscle Portland Cement Concrete Surface Course and the complementary product of pitch mixed layer, is the novel road surface structure that a kind of one-plus-one is greater than two.
