Abstract
A material for highway bed contains the mixture of sand, clay and broken stone (55-80 wt.%), light burnt magnesium (9-30), halogen flakes (10-25), modifier (0.55-1.35), water-proofing agent and water-reducing agent. A method for building up highway bed with said material is also disclosed, which features use of Cl-O-Mg cementing material to solidify the highway bed into a whole without local deformation under heavy load. Its advantages include low water content and water absorption, high freeze-thaw resistance and no cracking and "generating slurry".
Description
The present invention relates to the making of highway, relate in particular to highway subgrade material and highway subgrade paving method.
Existing highway subgrade material is by soil layer, and metalling and layer of sand constitute.During the making highway subgrade,, use the street roller compacting at smooth good roadbed weight-bearing surface upper berth soil layer; Then, at the soil layer upper berth of compacting metalling, use the street roller compacting; At last, sand bedding on the metalling of compacting is used the street roller compacting, thereby forms satisfactory roadbed.According to the different requirements of road pavement, can use the street roller compacting at the roadbed upper surface petrolize mixing bed of material or the cement concrete bed of material, form the highway pavement layer, finish the making of highway.Adopt the roadbed of prior art making, raw materials used is soil, rubble and sand, although each layer all used the street roller compacting, but because of wherein not containing adhesive material, therefore, this roadbed can not form an integral body, easily produce local deformaton during load-bearing, the road surface is become be uneven.Even more serious is, this roadbed that can not form one has higher water-intake rate, and freeze-thaw resistance is poor, under the situation that winter in summer high and low temperature changes, easily produces " returning slurry " phenomenon, and the road surface is cracked, and final damage.
The highway subgrade material that the purpose of this invention is to provide a kind of difficult generation local deformaton and " returning slurry " phenomenon.
Another object of the present invention provides a kind of method of making highway subgrade.
According to one object of the present invention, a kind of highway subgrade material is provided, comprises: two or more mixture 55-80 (weight) % of (1) sand, soil, rubble or they, (2) magnesia unslacked 9-30 (weight) %, (3) halogen sheet 10-25 (weight) %, (4) properties-correcting agent 0.55-1.35 (weight) %.
Properties-correcting agent can be two or more mixture of water-resisting agent, water reducer, formaldehyde, phosphoric acid, ammonium chloride, ferrous sulfate or they.
Water-resisting agent can be water glass, silicic acid two alum, silicic acid three alum.
Water reducer can be polyacrylic ester, naphthalene water reducer.
According to another object of the present invention, a kind of paving method of highway subgrade is provided, comprise the following steps:
(1) with a certain amount of halogen sheet, a certain amount of properties-correcting agent adds in a certain amount of water, is mixed with mixing solutions;
(2) two or more mixture and a certain amount of magnesia unslacked powder of a certain amount of sand, soil, rubble or they put into stirrer, fully mix, make mixture;
(3) will put into the stirrer of step (2) from a certain amount of mixing solutions that step (1) obtains,, make the roadbed material with mixture uniform mixing wherein;
(4) will be layered on from the roadbed material that step (3) obtain on the smooth good roadbed weight-bearing surface, and give tamping, thickness is 20-30cm, treat its spontaneous curing after, form highway subgrade.
Or after step (3), the roadbed material that is 10-15cm at smooth good roadbed weight-bearing surface upper berth one layer thickness is made bottom earlier, give tamping, on roadbed material bottom, place flat of the mao bamboon that a usefulness formaldehyde solution soaked or the clathrum of flat formation of reed then, be that the roadbed material of 10-15cm is made top layer at last at clathrum upper berth one layer thickness, give tamping, after treating bottom and top layer spontaneous curing, become one with the clathrum of flat of mao bamboon of soaking with formaldehyde solution or flat formation of reed, form highway subgrade.
Adopt in the highway subgrade material of highway subgrade paving method making of the present invention and contain magnesium oxychloride cementing material, it is as a whole that the roadbed material becomes after curing, can not produce local deformaton after load-bearing, and highway pavement is uneven; In addition, contain materials such as water-resisting agent and water reducer in this material, roadbed material curing back water ratio and water-intake rate be the end very, and the freeze-thaw resistance height, can not produce " returning slurry " phenomenon even under the situation that winter in summer high and low temperature alters a great deal yet, and the road surface can rhegma.
