Abstract
The present invention relates to highway construction technology, and is especially one kind of liquid curing agent for making road and its production process. The liquid curing agent consists of sodium hydroxide, sulfuric acid, phenol, rosin powder and soft water in certain proportion. The production process includes mixing rosin powder and phenol and heating in some container, adding solution of sodium hydroxide and heating to near 100 deg.c for 2 hr, and storing the mixture inside storing container while the mixture is still hot. During construction, the liquid curing agent is mixed with water repellent agent in the weight ratio of 1-2 to 8-9, and the mixture is then mixed with soil, sand and stone. The liquid curing agent is combined with soil to produce ion exchange reaction, and this can reduce or eliminate water film attached to soil, coagulate soil grains, reduce capillary effect and raise the water resisting and antifreezing performance of road bed.
Description
The present invention is for dividing an application its female case title " a kind of method of constructing roadway ", application number 02128770.8, August 6 2002 applying date.
Technical field
The present invention relates to highway construction field, particularly a kind of liquid curing agent for making road and manufacture method thereof.
Background technology
Present known constructing highway method is such (as shown in Figure 1): at first with the density of ready roadbed steamroller to regulation; Then, ready subgrade soil is mixed lime or cement, or the mixture of the two, mix is even, adds the real formation of hydraulic pressure subbase again; Then, more ready rubble (being generally graded broken stone, natural shode stone, i.e. sandstone) is mixed cement in proportion or the lime mix is even, add water to specified moisture content, roll and become and go up basic unit, spread asphalt wearing layer at last and get final product.
The shortcoming of prior art is: this method of constructing roadway needs thicker subbase of making and last basic unit, especially goes up basic unit and need use a large amount of sandstone material.Build highway in the place that lacks the sandstone material, must be from far place transportation, cost is very high, and a lot of places even cost of transportation surpass the price of sandstone material.In addition, subbase requires the thicker of laying in the prior art, thereby need expend a large amount of cement and lime, thereby cost is higher.
Summary of the invention
Task of the present invention is the shortcoming that overcomes prior art, and a kind of new method of constructing roadway that the cost of building the road is reduced significantly, the required solid curing agent of using of this method, liquid curing-agent and the latter's manufacture method is provided.
Technical scheme of the present invention is as follows:
A kind of method of constructing roadway, its operation is: making roadbed at first, making basic unit thereon then, making asphalt wearing layer in basic unit at last, it is characterized in that described basic unit has only one deck, and it is to roll after being mixed by weight ratio by soil, sandstone, liquid curing-agent and solid curing agent to form, and its proportioning is: soil: sandstone: liquid curing-agent: solid curing agent=1: 0.2-0.4: 0.001-0.015: 0.05-0.25.
The chemical composition of solid curing agent consists of (weight percentage):
1) silica (SiO
2) 10-40%;
2) alundum (Al (Al
2O
3) 5-25%;
3) calcium oxide (CaO) 30-65%;
4) magnesia (MgO) 0-7%;
5) sulfur trioxide (SO
3) 3-30%;
6) sulphate activation agent 1-5%.
Wherein said sulfate is Na
2SO
4, Al
2(SO
4)
3Or both mixtures.
Wherein said liquid curing-agent calculates by weight, and its component is:
Caustic soda 2-8;
Sulfuric acid 1-5;
Phenol 20-40;
Colophony powder 60-80;
Soft water is an amount of.
The manufacture method of described liquid curing-agent is:
1) earlier allocates colophony powder, phenol, sulfuric acid into container in proportion, slowly heat and stir, and temperature is controlled between 70-80 ℃, be incubated 4-10 hour;
2) suspend heating, add soda bath in container, continue heating 2-3 hour then, temperature is controlled between 80-100 ℃;
3) heating finishes, and while hot the mixture in the container is poured in the reservoir, during site operation, it is pressed 1-2: after the weight proportion of 8-9 and the water repellent agent dilution, just can mix with soil, sandstone and roll basic unit.
Build highway with method of the present invention, because no longer needing to transport from afar sandstone comes basic unit on the making, also no longer need the making subbase, roll the basic unit that just can constitute novel homogenous material and only need utilize on-the-spot soil to sneak into the sandstone of 20-35% and liquid curing-agent and solid curing agent mix.Thereby build highway with method of the present invention and can reduce the consumption of sandstone material significantly, thereby saved the cost of long-distance transportation; Owing to adopted new roadbed material, satisfying under the situation of same designing requirement on the other hand, can also make basic unit compared to prior art thickness reduce half, the cost of building the road further is reduced.
Advantage of the present invention can be further specified from the mechanism of action of solid curing agent and liquid curing-agent.
The mechanism of action of solid curing agent is such: the used solid curing agent of the present invention is a kind of pale powder, behind itself and soil mix, under the briquetting pressure effect, closely contact between the particle, this curing compound aquation generates hydrated calcium silicate, zeolite and gel etc. near soil particle, makes clay particle surface form the setting and harden shell.The activation component of this curing compound is infiltrated granule interior and the effect of clay mineral generation physics by different way, can not form hydrosilicate, aluminate.After curing compound and soil mineral fully act on, phyllosilicate self is set up the space net structure, the cement that its reaction generates is the soil particle of glued dispersion securely, can further strengthen and reinforce this net structure, make it to become a kind of integral body with higher-strength, and the material after this curing, also have water stability and strength stability.Solid curing agent can also produce expansion in solidification process, its drying that can compensate firming body is shunk, and effectively prevents basic unit's breach, and breach is prolonged and asphalt wearing layer.
The mechanism of action of liquid curing-agent is as follows: liquid curing-agent is a kind of polymer emulsion, when it with after soil combines, with soil generation ion-exchange reactions, make attached to the water film thickness on the soil particle and reduce greatly, even destroy fully; Soil particle is produced effectively draw close and cohesion, significantly reduce the capillary water absorption phenomenon, make harmful water can't enter basic unit, thereby the performance indications such as water-fast, freeze proof of basic unit are met design requirement.
Description of drawings
Fig. 1 is the schematic cross-section that prior art builds an automobile road;
Fig. 2 is the present invention's the schematic cross-section that method of constructing roadway built an automobile road.
The specific embodiment
Among Fig. 1, the highway that prior art is built needs 4 layers of makings, and the bottom is a roadbed 1, is subbase 21 on it, on again be to go up basic unit 22, and be asphalt wearing layer 3 at last.Subbase 21 is combined into basic unit 2 with last basic unit 22.
Among Fig. 2, method of constructing roadway of the present invention, the same with prior art, at first be with of the requirement of roadbed 1 steamroller to regulation, making basic unit 2 on roadbed 1 is last then, and is the same with prior art, lays asphalt wearing layer 3 in basic unit 2.
Roll after basic unit 2 is mixed soil, sandstone, solid curing agent and liquid curing-agent specifically and form.
The weight proportion of soil, sandstone, solid curing agent and liquid curing-agent is:
Soil: sandstone: liquid curing-agent: solid curing agent=1: 0.2-0.4: 0.001-0.015: 0.05-0.25.
