Description
Technical field
The utility model belongs to highway engineering construction and maintenance technology field, it particularly relates to arrive a kind of hard and soft combination
Basic unit's cement concrete pavement.
Background technology
The basic unit of the current cement concrete pavement of China is mainly cement stabilized macadam (gravel) semi-rigid type base, its material
Characteristic determines that it has that dense water is poor, erosion resistibility is weaker is combined the deficiency such as not good with Portland Cement Concrete Surface Course, causes
Cement concrete pavement easily produces the diseases such as disconnected plate, crushing shell and plat-bottom escape.To reduce above-mentioned many diseases, hard and soft combination
Basic unit's cement concrete pavement arises at the historic moment.Hard and soft combined base can strengthen the contact performance with Portland Cement Concrete Surface Course, make
Pavement structure entirety stress, weakens plate bottom tension, and the generation in crack is reduced or avoided；Water shutoff, resistance effect can be played again, subtracted
Few Water Damage, prevents plat-bottom escape disease.
The content of the invention
The utility model provides a kind of hard and soft combined base cement concrete pavement, and semi-rigid type base can be reduced or avoided
Disconnected plate that cement concrete pavement is caused because surface layer/base Coating combination is bad, semi-rigid sub-base material is washed away etc., crushing shell,
The diseases such as plat-bottom escape.
A kind of hard and soft combined base cement concrete pavement described in the utility model, the cement concrete pavement is under
And on successively include semi-rigid type base 1, emulsification pitch penetration 2, flexbile base 3, modified emulsifying asphalt adhesion coating 4 and cement concrete
Surface layer 5.
A kind of hard and soft combined base cement concrete pavement described in the utility model, the semi-rigid type base 1 is by top
Cement stabilized macadam semi-rigid type base and bottom cement stabilized macadam semi-rigid underlayment composition.
A kind of hard and soft combined base cement concrete pavement described in the utility model, the thickness of the semi-rigid type base 1 34cm-
40cm。
A kind of hard and soft combined base cement concrete pavement described in the utility model, the bottom of the emulsification pitch penetration 2
Tightly it is provided with the tangerine pith layer of thick 2cm-3cm.
A kind of hard and soft combined base cement concrete pavement described in the utility model, the thickness of the flexbile base 3 6cm-
10cm。
A kind of hard and soft combined base cement concrete pavement described in the utility model, the flexbile base 3 is mixed for pitch
Material flexbile base is closed, selected from AC-16, AC-20, ATB-25 or ATB-30.
Compared with prior art, hard and soft combined base cement concrete pavement described in the utility model, its basic unit uses
Flexible asphalt and gravel stabilization base layer and cement stabilized macadam semi-rigid type base are combined, and can be uniformly transferred from coagulating cement
The load action of native surface layer, and with dense water energy more more preferable than traditional semi-rigid type base and scour resistance, advantageously reduce
The diseases such as cement concrete pavement common disconnected plate, crushing shell, plat-bottom escape, with good application value.
Brief description of the drawings
Fig. 1 is hard and soft combined base cement concrete pavement structure figure；It is semi-rigid type base -1, emulsification pitch penetration -2, soft
Property basic unit -3, modified emulsifying asphalt adhesion coating -4, Portland Cement Concrete Surface Course -5.
Specific embodiment
Hard and soft combined base cement concrete pavement described in the utility model is done into one with reference to specific embodiment
Step explanation, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of hard and soft combined base cement concrete pavement, includes that semi-rigid type base 1, emulsified asphalt is saturating successively from bottom to top
Layer 2, flexbile base 3, modified emulsifying asphalt adhesion coating 4 and Portland Cement Concrete Surface Course 5.The thickness of the semi-rigid type base 1 40cm.It is described soft
Property basic unit 3 thickness 10cm.The semi-rigid type base 1 is broken by the cement stabilized macadam semi-rigid type base on top and the cement stabilizing of bottom
The semi-rigid underlayment composition of stone.The flexbile base 3 is Asphalt Stabilized Macadam ATB-30 flexbile bases.
Embodiment 2
A kind of hard and soft combined base cement concrete pavement, includes that semi-rigid type base 1, emulsified asphalt is saturating successively from bottom to top
Layer 2, flexbile base 3, modified emulsifying asphalt adhesion coating 4 and Portland Cement Concrete Surface Course 5.The thickness of the semi-rigid type base 1 34cm.It is described soft
Property basic unit 3 thickness 4cm.The semi-rigid type base 1 is broken by the cement stabilized macadam semi-rigid type base on top and the cement stabilizing of bottom
The semi-rigid underlayment composition of stone.The flexbile base 3 is Asphalt Stabilized Macadam AC-16 flexbile bases.
Embodiment 3
A kind of hard and soft combined base cement concrete pavement, from bottom to top including semi-rigid type base 1, emulsification pitch penetration 2,
Flexbile base 3, modified emulsifying asphalt adhesion coating 4 and Portland Cement Concrete Surface Course 5.The semi-rigid type base 1 by top cement stabilizing
The semi-rigid underlayment composition of cement stabilized macadam of rubble semi-rigid type base and bottom.The thickness of the semi-rigid type base 1 34cm-
