Ramming material mixing preparation method for material.
Background technique
Chromatic bitumen mixture is that one kind is formed by cementitious matter, mineral material, colorant and modifying agent blending and modifying, is had
The pavement of road paver for the features such as performance is stable, bright in colour, pavement performance is good, can be made different face as needed
Color.
Government road department is worked well in highway construction process using chromatic bitumen mixture laying road at present.Such as
On road in black spot, or by middle and primary schools school district, making red or orange-yellow asphalt are improved
Driver's is vigilant, drives a vehicle with caution；Or the asphalt of different colours was used to distinguish difference on the road surface of multilane
Lane.
The existing Colorful Asphalt Pavement bad phenomenon that there are weatherabilities is poor, the service life is shorter, color is thin out at present.Especially
It is in pavement diseases, the resistance such as the southern area that temperature is high, relative humidity is big, rainfall is big there is also track, deformation, film fall off
The popularization and use of chromatic bitumen mixture are hindered.
Summary of the invention
The object of the present invention is to provide a kind of chromatic bitumen mixture preparation method, the present invention has simple, easy to operate, steady
Fixed advantage.The resistance to environmental change of prepared product color, good high-temperature stability, low-temperature cracking-resistance, ageing resistance spy
Point.
The object of the invention can be realized by technical solution below:
A kind of chromatic cementing agent mixing preparation method for material, chromatic bitumen mixture component by mass percentage by below at
It is grouped as:
Wherein cementitious matter consists of the following compositions by mass percentage:

3. after cementitious matter is heated to 155-180 DEG C of thawing, antistripping agent being added and reconciles uniformly, is subsequently poured into stirred tank
It is interior；
4. 40-60s is stirred between 165-185 DEG C maintaining the temperature in stirred tank, until mixture uniformity, mineral aggregate
Particle all wraps cementitious matter, no flower material, no conglomeration or block or serious coarse fodder fines segregation phenomenon, obtains finished product.
Flower material refers to pitch and building stones in stirring, and the uneven a part package pitch that generates of stirring is especially more, a part of
There are no package to the problem of.
It includes that pitch is especially more that conglomeration or block, which refer to that pitch and building stones have part in stirring, forms biggish group or block.
Serious coarse fodder fines isolation refers to that in stirring, coarse fodder part and fine fraction separation are serious, is not uniformly mixed.
The present invention can be done to be improved further below:
The inorganic toner is preferably iron oxide red, iron oxide yellow, iron oxide green or chromium oxide.
The antistripping agent is preferably amino amine derivative liquid antistripping agent, and the effect of antistripping agent is to prevent cementitious matter
It is separated with mineral aggregate, it is more preferable using its effect of amino amine derivative liquid antistripping agent that inventor studies discovery.
Compared with prior art, the invention has the following advantages:
1) production equipment used by this preparation method is similar to the production production equipment of asphalt concrete, does not need
Increase additional equipment, to increase cost.
2) product made of the present invention is more preferable than plain asphalt in high-temperature stability, low-temperature cracking-resistance, ageing resistance, with
SBS modified asphalt mixture, which is compared, has better crack resistance at low-temperature；Meet the requirement of domestic communication standard.
3) product made of the present invention adjusts its additional amount, can spread out different colours by adding different inorganic toners
Road surface.
4) the road surface good weatherability that product made of the present invention is laid with is less prone to track, the road surfaces disease such as deformation, film fall off
Evil.
