Description
Technical field
The invention belongs to asphalt road surface field of material technology, is related to a kind of Cold bituminous mixture and its detail design
Method.
Background technology
With rapid development of economy, requirement more and more higher of the people to various material lifes, to capital construction also progressively
Bring up to new height and starting point, safety and comfort, economical and efficient, energy-conserving and environment-protective become the important topic of future development, development with
This contradiction of environmental protection and the law of unity of opposites are day by day highlighted, and some have argued that environmental protection and economy development is opposition, it is believed that
Environmental protection is wanted to sacrifice expanding economy.These years it was verified that the relation of correct processing environment and development, the two
Can be what is mutually promoted, the coordinated development of economy and environment can be reached, pavement engineering is also such.
What Chinese overwhelming majority bituminous paving was used is all hot-mix asphalt mixture, also just because of hot-mix asphalt mixture
The a part of deficiency of itself such as high temperature construction high energy consumption, operation be numerous and diverse and seriously polluted, brings to the construction of bituminous paving
A series of technical barrier, while also limit asphalt material in following development in pavement material field.It is mixed based on hot asphalt
Close a variety of drawbacks and the environmental problem that goes from bad to worse of material, asphalt pavement material just towards the continuous advance of energy-saving and emission-reduction, from
Heat is mixed warm mix, mixes and stirs from warm mix to normal temperature, mixes and stirs to cold mixing from normal temperature, depicts the scientific and technological progress direction of asphalt.
Today, the concern of global road bound pair bituminous paving energy-conserving and emission-cutting technology reaches and boils over, after warm-mixed asphalt pavement technique,
Normal temperature is mixed and stirred, cold-mix asphalt pavement technique becomes the focus of global development.
According to the definition of American National bituminous paving association NAPA, hot-mix asphalt mixture mixes and stirs temperature 150~180
DEG C, Warm-Mix Bitumen Mixture mixes and stirs temperature at 120~140 DEG C, and normal temperature mixes and stirs asphalt and mixes and stirs temperature 60~100
DEG C, cold-mix asphalt compound mixes and stirs temperature at 20~40 DEG C.Be not difficult to find out according to temperature is mixed and stirred, effects of energy saving and emission reduction it is still further preferred that
Cold-mix asphalt compound, next to that normal temperature mixes and stirs asphalt, but not enough its of cold-mix asphalt Asphalt Mixture is stranded for a long time
Disturb the factor of its application, and normal temperature to mix and stir Asphalt Mixture Performance identical with warm mix, the more advantage in terms of energy-saving and emission-reduction.
Cold bituminous mixture belongs to road-making material more new in the world, and theoretical research is more ripe, but entity work
Journey is few, more without the design and construction method of accurate, system, in consideration of it, proposing the present invention.

Part, determines voidage, Marshall stability, flow valuve and the saturation degree of the Cold bituminous mixture of different pitches consumption.Test
As a result as table 3 and Fig. 3 (a), Fig. 3 (b), Fig. 3 (c), Fig. 3 (d) are shown.
The Cold bituminous mixture AC-13 levels of table 3 match somebody with somebody indices measurement result
Take the asphalt content a corresponding to maximum theory density1=4.0%, the asphalt content a corresponding to maximum stable degree2=
4.4%, the asphalt content a corresponding to voidage scope intermediate value that specification specifies3=5.2%, obtain asphalt content initial value OAC1
=(a1+a2+a3)/3=4.53%；Take specification and specify that meeting stability, flow valuve, voidage, the pitch of four indexs of saturation degree uses
Maximum OAC that amount scope is occured simultaneouslymax=5.2% with minimum of a value OACmin=4.4%, obtain OAC2=(OACmax+OACmin)/2
=4.8%, comprehensive analysis OAC1With OAC2, the final asphalt optimum content OAC for determining Cold bituminous mixture is 4.8%, while
Also obtained under asphalt optimum content, optimal compaction voidage VV of novel normal-temperature asphaltOACFor 4.675%.
4th, optimal compaction voidage VV of the Cold bituminous mixture that judgement is obtainedOAC, recommending voidage %~6% model
In enclosing, continue income next step.
5th, according to Cold bituminous mixture mix temperature TEM for obtainingOAC：95 DEG C, produce Cold bituminous mixture, making 4
Section test section, 6 centimeters of construction depth, the steel roller of the same tonnage of the same model of per section of employing at a same speed, grinds
The different number of times of pressure, first paragraph rolls 2 times, second segment rolls to roll for 3 times, the 3rd section and roll 5 times 4 times, the 4th section (road roller is rolled
One comes and goes as 1 time), conditioned time TIM to be achievedOAC：After 12 days, in the diverse location coring of each test section 4, test
The average void fraction result for calculating each test section is as shown in the table.
The Cold bituminous mixture rolling layer of table 4 and voidage measurement result
Method using linear regression is as shown below, obtains returning between number of machine passes and Cold bituminous mixture voidage
Return equation：
Y=-1.037x+0.962 (1)
R2=0.9322 (2)
Bring optimal compaction voidage VV intoOAC：4.675%, obtain the optimal rolling layer of such Cold bituminous mixture construction
NUMOACFor 4.11 ≈ 4 times.
Finally give the execution conditions of such Cold bituminous mixture：Temperature TEM is mixed and stirred in constructionOAC：95 DEG C, compacting temperature
