Abstract

The invention discloses a pavement having an interlaminar embedded coordination structure. The principle of the interlaminar embedded coordination structure comprises that an upper surface of a lower pavement layer is provided with concave parts and convex parts or has a concave-convex structure; and a lower surface of an upper pavement layer is provided with concave parts and convex parts or has a concave-convex structure, wherein the concave parts and the convex parts or the concave-convex structure of the lower surface of the upper pavement layer can coordinate with that of the upper surface of the lower pavement layer. When pavement building is completed, the lower surface of the upper pavement layer and the upper surface of the lower pavement layer form an interlaminar embedded coordination structure in a pavement vertical section direction, and in other words, the interlaminar embedded coordination structure is formed between the upper pavement layer and the lower pavement layer. The pavement having an interlaminar embedded coordination structure has the advantages that the concave parts and the convex parts or the concave-convex structures are formed between the upper pavement layer and the lower pavement layer, so that a contact area of the upper pavement layer and the lower pavement layer is increased and the cohesiveness of the upper pavement layer and the lower pavement layer is enhanced; and the interlaminar embedded coordination structure is formed between the upper pavement layer and the lower pavement layer so that inclined plane contact between the upper pavement layer and the lower pavement layer is formed in a driving direction, and thus upper pavement layer horizontal displacement which is formed in the driving direction and is caused by a horizontal load is stopped; pavement upheavals are reduced; and a pavement service life is improved.

Background technology
Semi-rigid pavement is the principal mode of China's road structure, and semi-rigid pavement comprises basic unit and surface layer.Basic unit is usually said rigid layer, generally constitutes by three layers, is respectively subbase, middle basic unit and last basic unit; Surface layer is flexible layer, is three layers also generally, is respectively down surface layer, middle surface layer and upper layer.
The adhesive property of each interlayer of road surface is an important indicator of weighing pavement quality, adopts traditional construction technology, after laying of roadway is accomplished by layer, because the steel wheel of traditional pavement compaction machinery all is a cylindrical structure, so the visual effect of each layer is the plane.And the adhesive property of each interlayer of road surface depends on the natural bond state decision of consolidation effect and compacting back plane interlayer, this dependence be mutual adhesive effect and the mutual frictional force of interlayer between materials at two layers.For improving the interlaminar bonding effect, interlayer extensively adopts pitch to spill the shop technology at present, and the raising of this technology road pavement interlaminar bonding performance has good effect.But this bond state does not change road surface interlayer structure (being still to be plane contact between supercrust); When there being the horizontal load effect; And when horizontal load is big, still can cause the slip between supercrust, thereby the relative displacement that makes upper strata, road surface and base course produce horizontal direction.
Vehicle start is the major reason that causes the road surface interlaminar failure with the effect repeatedly of the horizontal load road pavement that braking is produced, so the adhesive property between once strong supercrust, the shear ability that improves between supercrust is the effective way that improves service life of road surface.
Summary of the invention
The purpose of this invention is to provide the embedded road structure of a kind of interlayer, thereby can strengthen at adhesive property between supercrust and anti-shear ability under the horizontal load effect.
What the present invention adopted is to increase the contact area between supercrust and make the technical scheme that forms local damascene structures between supercrust.The invention discloses the embedded road structure of a kind of interlayer; The contact surface of road surface, upper strata and underpavement is between supercrust; It is characterized in that along the vertical section of road surface direction, the soffit on road surface, upper strata and the upper surface of underpavement are to be the embedded fit structure of interlayer between supercrust.
As preferably, the upper surface of underpavement has concave configuration, and the soffit on road surface, upper strata has the following male structure that cooperates with this concave configuration.
As preferably, the upper surface of underpavement has convex configuration, and the soffit on road surface, upper strata has the fovea superior structure that cooperates with this convex configuration.
As preferably, the upper surface of underpavement has recessed and convex configuration, and the soffit on road surface, upper strata has and this recessed following protruding and fovea superior structure that cooperates with convex configuration.
Recessed, the epirelief of said underpavement or recessed and convex configuration, and following protruding, the fovea superior on road surface, upper strata or protruding and fovea superior structure (being the embedded fit structure between supercrust) down, shape can or be uniformly distributed with spherical cap structure for arc, trapezoidal, triangle.
The invention has the beneficial effects as follows: make between supercrust and go up formation embedded texture structure (curved surface texture structure) along longitudinal section (section of direction of traffic); The embedded texture structure of this interlayer not only can increase the contact area of road surface, upper strata and underpavement; And underpavement and road surface, upper strata form embedded fit structure; Make and on direction of traffic, form the inclined-plane contact between supercrust; Thereby can hinder the horizontal movement of road surface, upper strata on horizontal load effect down train direction, improve the adhesive property and the anti-shear ability of road surface interlayer under the horizontal load effect.
