Abstract
The utility model discloses a road pavement structure, and in particular relates to an asphalt concrete pavement structure for plateau area, with higher temperature change adaptability and higher quick-drying and drainage performance. The road pavement structure sequentially comprises a base layer, a mortar adhering layer, a crushed stone layer, a slurry seal layer combined with priming oil, a coarse grain type asphalt concrete layer, an intermediate grain type asphalt concrete layer and a rubber asphalt layer, wherein the base layer is a concrete stable grain base layer, and the crushed stone layer comprises crushed stones and stone chips filling the clearances among the crushed stones.
Description
Technical field
The utility model relates to highway construction technical field, particularly relates to a kind of asphalt concrete pavement structure for highlands.
Background technology
As everyone knows, asphalt concrete pavement is a kind of road that adopts bituminous concrete to lay, and because of its good moulding and higher construction and maintenance efficiency, is widely used in highway construction field; Existing asphalt concrete pavement structure, conventionally comprise successively from down to up basic unit, in conjunction with slurry seal and the surface layer of priming oil, surface layer comprises surface layer and particulate formula bituminous concrete upper layer in surface layer under Coarse Graded Bituminous Concrete, middle grain formula bituminous concrete from the bottom to top successively; The effect of the analysis of wheel vertical power of surface layer transmission is mainly born by basic unit, and it is diffused into bed course and the soil matrix of below, slurry seal is for confining surface space, prevents that moisture from invading the certain thickness bituminous mixture thin layer that has of making in Er basic unit, priming oil is in order to make asphalt surface course Yu Fei bituminous material basic unit in conjunction with good, spraying liquid petroleum bitumen in Er basic unit, mulseal, coal tar pitch and the thin layer that penetrates substrate surface certain depth that forms, surface layer bears the effect of analysis of wheel vertical power and is diffused to basic unit; This asphalt concrete pavement structure, can be applied to preferably in urban highway traffic, yet in highlands, because day and night temperature is larger, Changes in weather speed, so just requires road structure to have higher variations in temperature adaptive capacity, higher quick-drying and drainage performance, and asphalt concrete pavement structure of the prior art is difficult to meet this requirement, the situation that after using for a long time, easily appearance is ftractureed, basic unit is empty by water erosion, even collapse.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of higher variations in temperature adaptive capacity that has, the asphalt concrete pavement structure for highlands of higher quick-drying and drainage performance.
Asphalt concrete pavement structure for highlands of the present utility model, comprise the basic unit, mortar adhering layer, macadam, the slurry seal in conjunction with priming oil, Coarse Graded Bituminous Concrete layer, middle grain formula asphalt concrete layer and the rubber asphalt layer that cover successively from the bottom to top, described basic unit is cement stabilized granular base course, the aggregate chips that described macadam comprises rubble and is filled in hole between described rubble.
Further, in described basic unit, be provided with the pipe of cement of vertical road bearing of trend.
Further, the thickness of described basic unit is 30-40cm, and the thickness of described mortar adhering layer is 2-3cm, and the thickness of described macadam is 10-15cm.
Compared with prior art the beneficial effects of the utility model are: comprise the basic unit, mortar adhering layer, macadam, the slurry seal in conjunction with priming oil, Coarse Graded Bituminous Concrete layer, middle grain formula asphalt concrete layer and the rubber asphalt layer that cover successively from the bottom to top, basic unit is cement stabilized granular base course, the aggregate chips that macadam comprises rubble and is filled in hole between rubble, like this, cement stabilized granular base course can prevent rainwash effectively, enough rigid support are provided simultaneously, even if its modulus of deformation also can maintain 800-1000 kilograms/square centimeters under wet environment, mortar adhering layer supports and cushions macadam effectively, and the macadam that the mutual interlocking of rubble and aggregate chips forms, compactness and stability are higher, can effectively support road surface, and the effect of analysis of wheel vertical power comparatively evenly and is dispersedly diffused to basic unit, in addition, macadam is higher to the adaptive capacity of temperature shock, be laid on the bituminous concrete on macadam, also the situation that is difficult to occur crack after long-term use, in conjunction with the slurry seal of priming oil, can effectively prevent that moisture from corroding basic unit, Coarse Graded Bituminous Concrete layer and middle grain formula asphalt concrete layer, can effectively support and cushion rubber asphalt layer, and rubber asphalt is owing to having good high-temperature stability, low temperature flexibility, ageing resistance, fatigue resistance, water resistant damageability, is the better selection as top layer, road surface, highlands.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, asphalt concrete pavement structure for highlands of the present utility model, comprise the basic unit 1, mortar adhering layer 2, macadam 3, the slurry seal 4 in conjunction with priming oil, Coarse Graded Bituminous Concrete layer 5, middle grain formula asphalt concrete layer 6 and the rubber asphalt layer 7 that cover successively from the bottom to top, basic unit is cement stabilized granular base course, the aggregate chips that macadam comprises rubble and is filled in hole between rubble, like this, cement stabilized granular base course can prevent rainwash effectively, enough rigid support are provided simultaneously, even if its modulus of deformation also can maintain 800-1000 kilograms/square centimeters under wet environment, mortar adhering layer supports and cushions macadam effectively, and the macadam that the mutual interlocking of rubble and aggregate chips forms, compactness and stability are higher, can effectively support road surface, and the effect of analysis of wheel vertical power comparatively evenly and is dispersedly diffused to basic unit, in addition, macadam is higher to the adaptive capacity of temperature shock, be laid on the bituminous concrete on macadam, also the situation that is difficult to occur crack after long-term use, in conjunction with the slurry seal of priming oil, can effectively prevent that moisture from corroding basic unit, Coarse Graded Bituminous Concrete layer and middle grain formula asphalt concrete layer, can effectively support and cushion rubber asphalt layer, and rubber asphalt is owing to having good high-temperature stability, low temperature flexibility, ageing resistance, fatigue resistance, water resistant damageability, is the better selection as top layer, road surface, highlands.
Altitude environment weather is fast changing, especially summer rainwater is more, easily form in a large number along the catadromous streams of mountain shape, for fear of streams, in road one side, accumulate, and wash away road, in basic unit, be provided with the pipe of cement 8 of vertical road bearing of trend, drainage rainwater so effectively, the application life of having improved road.
In order effectively to support asphalt concrete pavement, the thickness of basic unit is 30-40cm, and the thickness of mortar adhering layer is 2-3cm, and the thickness of macadam is 10-15cm.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
