Description
Technical field
The present invention relates to Highway Pavement Structures technical field of improvement, specifically relate to a kind of using building waste as basic unit
The light traffic Highway Pavement Structures of material.
Background technology
With the development of urban construction, large quantities of old buildings are removed, and generate substantial amounts of building waste.According to the Ministry of Construction
Promulgate within 2005《Urban building waste administrative provisions》, building waste refers to construction unit, newly-built unit in charge of construction, reconstruction, expansion
Build and remove produced spoir during all kinds of buildings, structures, pipe network etc. and resident's decorations house, rejected material and
Other discarded objects.According to correlative study, China's building waste yield is typically about the 30% of municipal refuse total amount, and annual yield reaches
50000000 tons.
Into 21 century, the severe challenge of facing mankind shortage of resources and natural environment deterioration.China human mortality is numerous, is in
The critical period of economic development, how to realize the recycling of waste resource, reduce carrying capacity of environment, be that China environmental protection and can hold
One of target of supervention exhibition, there is very big realistic meaning to building a harmonious society.In view of building waste and other municipal refuses
Compare, building waste has the characteristics of measuring big, nontoxic and resourcebility rate high.Meanwhile, with road and construction industry construction
Develop rapidly, natural aggregate resources are by increasingly depleted.Building waste is applied to highway engineering, environmental pollution can be reduced,
Natural resources can be saved again, reduce engineering input.
In field of road, the solids such as spoir, discarded concrete, discarded brick that are mostly of construction refuse regenerated application give up
Gurry.Wherein discarded concrete, discarded brick recycle complexity, are the emphasis of research.China processes approach and will mainly build at present
Filling material or concentration landfill and stacking of the building refuse as basement process, the treatment of annual newly-increased building waste will all be accounted for
1.5 hundred million to 200,000,000 square metres of lands used, undressed building waste can influence air quality, polluted water resources and land resource.
《Highway cement concrete pavement design specification》(JTG D40-2011) specifies, Design Lane design reference period internal standard
What fiducial axis carried accumulative effect times N e ＜ 3 × 104 times is light traffic grade.The present invention according to《Highway cement concrete pavement
Design specification》The requirement that light traffic is related in (JTG D40-2011) is studied building waste in basic unit's application aspect,

Groundwork thickness Computing Principle
The basic unit of present invention research is cement stabilizing building waste, belongs to inorganic binder class basic unit, existing according to China
Specification《Highway cement concrete pavement design specification》(JTG/D40-2011), pavement structure is according to elastic foundation individual layer Slab
It is designed.
《Highway cement concrete pavement design specification》(JTG/D40-2011) stabilized with inorganic binder pellet base is recommended in
The general suitable compacted depth scope of layer is 150mm-200mm,《Trackbed inspection》Chapter 9, cement concrete is described on
Sub-surface thickness is advisable with 20cm or so, and research data shows that basic thickness should not be too thin, also blocked up should not cause cost mistake
Height, the minimum thickness of Pavement Design software HPDS2001 limitation cement stabilized base courses is 80cm, and maximum gauge is 350cm, due to
Building waste does not have related specifications as base material, therefore thickness range will be recommended to be set to 80mm-350mm when calculating.
Whether groundwork thickness meets requirement, need to only check the limiting condition i.e. γ of laminar(σpr+σtr) (consider reliability
Concrete surface laminate synthesis fatigue stress after coefficient) and γr(σpmax+σtmax) (concrete topping is maximum after considering safety index
Combined stress) whether meet requirement.
Calculating parameter is selected
Design traffic volume is chosen
The application main study subject is light traffic highway cement concrete pavement, foundation《Highway cement concrete road
Face design specification》(JTG/D40-2011), light traffic grade refers to Design Lane design reference period internal standard fiducial axis and carries accumulative work
With times N e ＜ 3 × 104 times.Therefore, design traffic volume takes maximum 30000 times, to the highway cement coagulation under this volume of traffic
Soil surface Rational Thickness is studied.If the least favorable situation volume of traffic can meet code requirement for 30000 times, remaining volume of traffic feelings
Condition can meet code requirement.
Pavement structure width
Light traffic highway is generally country road, and township road is generally Class III highway in rural highway, and village road is generally Class IV highway,
《County Highway Cement Concrete Pavement Design and construction》In to the regulation of County Highway width of roadway, Class III highway width of roadway
It is 7.0m or 6.5m, Class IV highway width of roadway is 6.0m or 3.5m, therefore it is 3.25m to take the width of cement concrete slab.
Because the length-width ratio of cement concrete pavement surface plate is no more than 1.30, therefore plate is long is taken as 4.0m.
Pavement material parameters are chosen
(1) soil matrix
The soil property major part of southwest is liquid limit silty clay high, according to《Highway cement concrete pavement design specification》
(JTG/D40-2011) reference value of Rebound Modulus of Subgrade design parameter selection, high liquid limit clay Rebound Modulus of Subgrade value are given
Scope is between 20MPa~50MPa, liquid limit silt Rebound Modulus of Subgrade span high is between 30MPa~70MPa.Therefore
Rebound Modulus of Subgrade is taken as 50MPa.
(2) underlayment
Base level is to want supporting course or auxiliary layer, relatively low with respect to being required for basic unit, can select second-rate material
Carry out making.The main material that basic unit uses is building waste, then underlayment can remove the slightly lower lime fly ash of intensity
Used as base material, underlayment chooses lime fly ash in the calculation, through consulting bibliography《High-grade highway two-ash broken stones base
The Comprehensive Assessment of layer material pavement performance and rational proportion are studied》《The reasonable layer position of semi-rigid type base and Rational Thickness research》《Again
The raw utilization in roadbase of gathering materials》, the compression rebound modulu of underlayment takes 400MPa.Thickness is designed as 20cm.
(3) surface layer
The category of roads of this research is light traffic grade, and cement concrete flexural tensile strength standard value takes 4MPa.Concrete
Moment design value is 27000MPa.Surface thickness is definite value 20cm.
Other design ratios are chosen
The equal foundation of each term coefficient involved in calculating《Highway cement concrete pavement design specification》(JTG/D40-
2011) regulation is chosen.Specific value is as follows：
(1) stress reduction factor kr
The two-lane highway longitudinal joint of inferior grade is the flush joint for not setting pull bar, and through tabling look-up, stress reduction factor is taken as 0.87.
(2) fatigue stress coefficient kf
The fatigue stress coefficient kf=Nev, Ne of the accumulative fatigue effect of design reference period internal loading stress represent design basis
The accumulative effect number of times of Design Lane standard load in phase；V is the index relevant with Properties of Asphalt Mixture, normal concrete, v=
0.057.The numerical value of kf changes with the change of Ne.
(3) coefficient of colligation kc
Road quality classification is different, and the coefficient of colligation kc of the factor road pavement such as unbalance loading and dynamic load fatigue damage influence is also different.It is right
In three, Class IV highway, kc=1.10.
(4) maximum temperature gradient Tg
Southwest is Vth area, therefore maximum temperature gradient takes 88.
(5) safety index γr
Consider according to Class IV highway in view of light traffic highway, the safe class of Class IV highway is level Four, and target can
It is 80 by degree.So corresponding Deflection level grade is senior, therefore through determination=1.11% of tabling look-up.
