Abstract
The invention discloses recycled asphalt concrete containing cement and a usage method thereof in repair of small roads. The recycled asphalt concrete containing cement is prepared by old asphalt concrete, asphalt, cement and stones of a specification; wherein addition of cement is 3-7wt% of the total weight of the old asphalt concrete and the stones of a specification, the addition of the asphalt is 2-4wt% of the total weight of the old asphalt concrete and the stones of a specification, and the addition of the stones of a specification is 40-60wt% of the amount of the old asphalt concrete. The old asphalt concrete which is shoveled and dug is used as a raw material in order to carry out regeneration, and the recycled asphalt concrete is obtained, so that high efficiency utilization of waste asphalt mixtures is realized, and effects of resource regeneration and resource saving are improved; in the process of small-sized repairing of roads, large-scale equipment is not needed for production, on-site construction is realized, paving time is shortened, and construction cost is saved.
Description
Technical field
The present invention relates to a kind of new concrete and using method thereof, particularly relate to a kind of cement again
Raw bituminous concrete and the using method in compact road is repaired thereof.
Background technology
Cement concrete has noise and greatly, easily plays dust, the shortcoming of joint treatment difficulty, Colophonium
Concrete has in the case of severe load and is easily generated rut, passage, winter easy bursting by freezing
Shortcoming.The shortcoming of above two concrete can be made up by cement pitch concrete, but
Exist during the small-sized repairing of road cost too high (needing asphalt mixing plant to produce),
The shortcoming that transport is inconvenient.
Summary of the invention
Lack to solve the above-mentioned of cement concrete, bituminous concrete and cement pitch concrete
Point, the invention provides a kind of new concrete cement Recycled Asphalt Pavement and small-sized
Using method in road repair.
It is an object of the invention to be achieved through the following technical solutions:
A kind of cement Recycled Asphalt Pavement, by old asphalt concrete, Colophonium, cement and number stone
It is prepared from, wherein: cement addition is old asphalt concrete and the 3～7wt% of number stone total amount,
Colophonium addition is old asphalt concrete and the 2～4wt% of number stone total amount, and a number stone addition is old
The 40～60wt% of bituminous concrete.
A kind of above-mentioned cement Recycled Asphalt Pavement using method in compact road is repaired, bag
Include following steps:
One, at the scene during road-surface milling, milling block old asphalt concrete out is entered
Row screening, reclaims particle diameter the carrying out of below 19mm；
Two, old asphalt concrete after sieving is proportionally initially charged cement and required specification
Number stone carry out dry stirring, to be mixed uniformly after add the Colophonium of about 140～160 DEG C and continue
Stirring, until stirring, then carries out road surface dress paving.
In the present invention, the particle diameter of described stone is at below 19mm.
In the present invention, described road surface is bituminous paving face layer.
The cement Recycled Asphalt Pavement that the present invention provides has the advantage that
1, carry out regenerating the regeneration asphalt obtained with milling old asphalt concrete out for raw material
Composite soil, can realize the efficient utilization of discarded asphalt, it is possible to reach to improve resource regeneration
With resource-effective effect；
2, during the small-sized repairing of road, it is not necessary to main equipment produces, can be on-the-spot
Construction, shortens the laying time, saves construction cost；
3, the properties of the cement Recycled Asphalt Pavement of preparation is excellent；
4, can effectively save building stones and the consumption of new Colophonium, reduce cost, be suitable for popularization and application.
Detailed description of the invention
Below technical scheme is further described, but is not limited thereto, all
It is technical solution of the present invention to be modified or equivalent, without deviating from the technology of the present invention side
The spirit and scope of case, all should contain in protection scope of the present invention.
Detailed description of the invention one: present embodiments provide for a kind of cement Recycled Asphalt Pavement,
It is prepared from, wherein by old asphalt concrete, Colophonium, cement and number stone: cement addition is
Old asphalt concrete and the 5wt% of number stone total amount, Colophonium addition be old asphalt concrete and number
The 2.5wt% of stone total amount, a number stone addition is the 50wt% of old asphalt concrete.
A kind of above-mentioned cement Recycled Asphalt Pavement using method in compact road is repaired, bag
Include following steps:
Job site need to have number stone of all size and the Colophonium of about 150 DEG C and cement,
During on-the-spot road-surface milling, milling old asphalt concrete out is sieved, particle diameter is existed
The carrying out of below 19mm is reclaimed, in old asphalt concrete after sieving first according to a certain percentage
Number stone of addition cement and required specification carries out dry stirring, and addition the most afterwards to be mixed is with one
The Colophonium of fixed temperature continues stirring, until stirring, then carries out road surface dress paving.
The dynamic stability of the cement Recycled Asphalt Pavement that present embodiment provides is shown in Table 1.
