Abstract
The utility model discloses a separate road. The separate road comprises a cushion layer and a base layer arranged on the cushion layer; a cement concrete pavement and a bituminous concrete pavement are paved on the base layer, a road segmentation line is arranged in the road extending direction between the cement concrete pavement and the bituminous concrete pavement, a road shoulder is arranged on the outer side edge of the cement concrete pavement, and the bituminous concrete pavement comprises a fine-grained bituminous top surface layer, a coarse-grained bituminous bottom surface layer and a medium-grained bituminous middle surface layer arranged between the fine-grained bituminous top surface layer and the coarse-grained bituminous bottom surface layer. According to the separate road, the advantages of strong rigidity and high bearing capability of the cement concrete pavement and the advantages of high planeness, comfort for driving and the like of the bituminous concrete pavement are sufficiently developed, vehicles are separated to run, and therefore, the traffic capacity of the road is improved and the service life of the road is prolonged.
Description
Technical field
The utility model relates to a kind of road structure, particularly relates to a kind of separate type road.
Background technology
The road surface form of China's speedway mainly contains two kinds of forms, i.e. flexible pavement and cement concrete pavement, and two kinds of road surface forms respectively have its advantage.The advantage of flexible pavement be surfacing without seam, driving vibration is little, noise is low, open to traffic is fast, maintenance is easy, is suitable for road surface stage construction, is the important structure form on China road surface; Its shortcoming is that temperature sensitivity is higher.Summer, intensity declined, if control bad meeting make road surface feel like jelly bellding or pass shear fracture destroy mulseal, when low temperature, bituminous material becomes fragile and may cause pavement cracking, when summer high temperature because flexible pavement temperature under high temperature is poor, carry under large vehicle effect and produce plastic strain at axle, be easy to the rut of driving a vehicle, the formation of rut has affected the comfortableness and the safety that form.The advantage of cement concrete pavement is that rigidity is large, and supporting capacity is strong; Durability, heat-resisting quantity are strong; Bending tensile strength is high, fatigue life is long; Long service life and be a kind of environment-friendly type road surface.At present flexible pavement is mainly as the road surface form of speedway and high-grade road, and cement concrete pavement is for inferior grade road.
Along with growing with each passing day of China's traffic volume, vehicle axle weight develops to large-tonnage, the use of new technology, automotive performance improves constantly, the speed of a motor vehicle is also to high speed future development, flexible pavement is as the main road surface form of speedway or high-grade highway, the fast car that passing through on road, the truck that the speed of a motor vehicle is low, load-carrying is large.On the one hand, traffic is blended on road, will certainly cause the vehicle that the speed of a motor vehicle is low to hinder the high vehicle pass-through of the speed of a motor vehicle, greatly reduces the traffic capacity of road; On the other hand, the great automobile of axle travels on flexible pavement, because flexible pavement is poor at hot environment stability inferior, under Vehicle Load, particularly, under the effect of truck, very easily forms rut, thus comfortableness and the safety of impact driving.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of separate type road is provided.This separate type road makes full use of that cement concrete pavement rigidity is large, supporting capacity is strong, and Bitumen Concrete Pavement Smoothness is high, comfortable etc. the advantage of driving a vehicle, and vehicle is separately travelled, and improved the traffic capacity and the application life of road.
For achieving the above object, the technical solution adopted in the utility model is: a kind of separate type road, it is characterized in that: comprise bed course and be arranged on the basic unit on bed course, in described basic unit, making has cement concrete pavement and asphalt concrete pavement, between described cement concrete pavement and flexible pavement, be provided with the road cut-off rule arranging along road bearing of trend, the outer ledge place of described cement concrete pavement is provided with curb, described flexible pavement comprises particulate formula asphalt uplayer, under coarse grain formula pitch surface layer and be arranged on particulate formula asphalt uplayer and coarse grain formula pitch under surface layer in middle grain formula pitch between surface layer.
Above-mentioned a kind of separate type road, is characterized in that: the thickness of described bed course is 15cm～25cm, and the thickness of described basic unit is 15cm～25cm, and the thickness of described cement concrete pavement is 20cm～25cm, and the thickness of described flexible pavement is 20cm～25cm.
Above-mentioned a kind of separate type road, is characterized in that: the thickness of described bed course is 20cm, and the thickness of described basic unit is 20cm, and the thickness of described cement concrete pavement is 20cm, and the thickness of described flexible pavement is 20cm.
Above-mentioned a kind of separate type road, is characterized in that: the thickness of described particulate formula asphalt uplayer is 4cm, and in described middle grain formula pitch, the thickness of surface layer is 6cm, and under described coarse grain formula pitch, the thickness of surface layer is 10cm.
The utility model compared with prior art has the following advantages:
This separate type road is the mode that longitudinal rigid road surface combines with flexible pavement, the general low vehicle of the speed of a motor vehicle travels on the right side of road, at right side making is cement concrete pavement, belong to rigid pavement, it can meet the vehicle pass-through that load-carrying is large, and traffic is separated, reduced the large automobile of load-carrying travels on flexible pavement, reduce the formation of asphalt pavement rut, will separate with slow-moving vehicle at a high speed, improved the traffic capacity of road.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
The specific embodiment
A kind of separate type road as shown in Figure 1, comprise bed course 6 and be arranged on the basic unit 5 on bed course 6, in described basic unit 5, making has cement concrete pavement 1 and asphalt concrete pavement 2, between described cement concrete pavement 1 and flexible pavement 2, be provided with the road cut-off rule 4 arranging along road bearing of trend, the outer ledge place of described cement concrete pavement 1 is provided with curb 3, described flexible pavement 2 comprises particulate formula asphalt uplayer 2-1, under coarse grain formula pitch surface layer 2-3 and be arranged on particulate formula asphalt uplayer 2-1 and coarse grain formula pitch under surface layer 2-2 in middle grain formula pitch between surface layer 2-3.
This separate type road is the mode that longitudinal rigid road surface combines with flexible pavement, the general low vehicle of the speed of a motor vehicle travels on the right side of road, at right side making is cement concrete pavement 1, belong to rigid pavement, it can meet the vehicle pass-through that load-carrying is large, and traffic is separated, reduced the large automobile of load-carrying travels on flexible pavement, reduce the formation of asphalt pavement rut, will separate with slow-moving vehicle at a high speed, improved the traffic capacity of road.
