Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 2 and Fig. 3, a kind of Highway Pavement Structures schematic diagram that Fig. 2 provides for the utility model embodiment, a kind of Highway Pavement Structures FRP grid layout schematic diagram that Fig. 3 provides for the utility model embodiment.
A kind of Highway Pavement Structures that the utility model embodiment provides, comprise: base course, middle level, road surface and base course, wherein base course is specially concrete material base course 1, middle level, road surface is specially middle level, AC-10 epoxy resin asphalt concrete material road surface 4, upper strata, road surface is specially upper strata, AC-13 modified asphalt concrete material road surface 5, at the top surface of concrete material base course 1, is bonded with FRP cloth 2.When road surface pavement structure, be followed successively by from the bottom to top concrete material base course 1, middle level, AC-10 epoxy resin asphalt concrete material road surface 4, upper strata, AC-13 modified asphalt concrete material road surface 5, be the top that middle level, AC-10 epoxy resin asphalt concrete material road surface 4 is arranged at concrete material base course, upper strata, AC-13 modified asphalt concrete material road surface 5 is arranged at the top in middle level, AC-10 epoxy resin asphalt concrete material road surface 4.The top surface that FRP cloth 2 is arranged at concrete material base course 1 refers to that FRP cloth 2 is arranged at the position that concrete material base course 1 is connected with middle level, AC-10 epoxy resin asphalt concrete material road surface 4.
FRP material is fiber reinforced polymer english abbreviation, be fibre reinforced composites, FRP cloth is fibre reinforced composites cloth, FRP cloth has good water resistance, compared with prior art, by FRP cloth is set, when highway ponding infiltrates into FRP cloth, FRP cloth can guarantee that ponding can not continue to leak into roadbed, ponding on FRP cloth 2 surfaces by transverse row to roadside ditch, can avoid roadbed because the immersion of ponding is permeated the differential settlement of the roadbed causing or softens, and then can guarantee the planarization on road surface.
In this specific embodiment, FRP cloth 2 the two-layer of the number of plies be set, because it has good water resistance, two-layer FRP cloth 2 can avoid ponding to infiltrate into the roadbed of concrete material base course below 1 completely, the FRP cloth of other numbers of plies also can be set according to concrete condition of construction certainly.
Simultaneously because the coefficient of expansion of FRP cloth is close with the concrete coefficient of expansion, middle level, AC-10 epoxy resin asphalt concrete material road surface 4 is arranged at the top of FRP cloth 2, FRP cloth 2 is arranged at the top surface of concrete material base course 1, therefore between middle level, AC-10 epoxy resin asphalt concrete material road surface 4 and concrete material base course 1, FRP cloth 2 being set can guarantee when environment temperature changes, three keeps identical thermal expansion amount, guarantee can not rupture because swell increment is different between three, further guarantee the planarization on road surface.
It should be noted that, in this specific embodiment, FRP waterproofing course is the formed waterproofing course of FRP cloth 2, and other forms of FRP waterproofing course can certainly be set according to concrete condition of construction.
Also it should be noted that, in this specific embodiment, middle level, AC-10 epoxy resin asphalt concrete material road surface 4 and the mutually bonding setting of FRP cloth 2, FRP cloth 2 and the bonding setting of concrete material base course 1, the cementing agent adopting is epoxy adhesive, certainly, according to actual condition of construction, do not get rid of the cementing agent that adopts other yet.
In addition, concrete material base course 1 also comprise cement stabilized macadam base 6 and two-layer FRP grid screen, cement stabilized macadam base 6 is arranged at the below of concrete material base course 1, wherein one deck the 2nd FRP grid screen 3 is arranged at the bottom of concrete material base course 1, and another layer FRP grid screen 7 is arranged at the bottom of cement stabilized macadam base 6.Because the intensity of FRP grid screen is suitable with the intensity of reinforcing bar, when than reinforcing bar, the corrosion resistance of FRP grid screen is strong, by FRP grid screen is set, can increase intensity and the holistic resistant behavior of concrete lower floor 1 and cement stabilized macadam base 6, can improve respectively the globality of concrete material base course 1 and cement stabilized macadam base 6, further guarantee the planarization of highway pavement.
It should be noted that, in this specific embodiment, concrete material base course 1 thickness is 26 centimetres, middle level, AC-10 epoxy resin asphalt concrete material road surface 4 thickness are 3 centimetres, upper strata, AC-13 modified asphalt concrete road surface 5 thickness are 3 centimetres, and cement stabilized macadam base 6 thickness can be 20 centimetres.Certainly, also can adopt other sizes according to design.
Also it should be noted that, in this specific embodiment, the mesh spacing of a FRP grid screen 7 and the 2nd FRP grid screen 3 can be 30 centimetres, and the width of FRP grid bar and thickness are 2 centimetres.Certainly, also can adopt other sizes according to design.
In this specific embodiment, in middle level, the bonding making AC-10 of upper surface epoxy resin asphalt concrete material road surface 4 compacting of FRP cloth 2 waterproofing courses; Upper strata, making AC-13 modified asphalt concrete road surface 5 pressure above middle level, AC-10 epoxy resin asphalt concrete material road surface 4.The diameter that gathers materials in the middle level, AC-10 epoxy resin asphalt concrete material road surface 4 of FRP cloth 2 tops is less and adopt epoxy resin adhesive to connect, with the major diameter of prior art gather materials contrary in the layout of bottom, guaranteed the to gather materials larger bonding surface that is connected with FRP cloth 2 and the reliability of connection.
In this specific embodiment, the top of FRP cloth 2 adopts the two-layer layout on middle level, AC-10 epoxy resin asphalt concrete material road surface 4 and upper strata, AC-13 modified asphalt concrete road surface 5, guaranteed the good water permeability in road surface in rainy season, ponding can transverse row on FRP cloth 2 to roadside ditch, guarantee road surface in rainy season ponding not, guaranteed traffic safety in rainy season.
Moreover in cement stabilized macadam base 6 bottoms, the one FRP grid 7 being set, FRP structural strength and steel approach, and increase by a FRP grid 7 and are equivalent to increase one deck steel mesh reinforcement in basic unit, increase the holistic resistant behavior of cement stabilized macadam base 6; The concrete bottom of concrete material base course 1 arranges after the 2nd FRP grid 3, FRP structural strength and steel approach, increase by the 2nd FRP grid 3 and be equivalent to increase one deck steel mesh reinforcement in the concrete of concrete material base course 1, increase concrete material base course 1 concrete holistic resistant behavior; The ability that the anti-differential settlement that has improved above-mentioned road structure is set of above-mentioned two-layer FRP grid, and then can guarantee the planarization on road surface.
