Abstract
The invention relates to a regenerated road cold feeding material, which comprises 56-87% milling material, 0.08-0.34% cold feeding additive, 0.87-1.6% diesel, and stones. The invention adds stone, feeding liquid, diesel, and macromolecule activate modified additive into the milling waste of highway, to be heated and mixed, to save material and reduce the pollution, while the added macromolecule activate modified additive can resolve the aging problem of pitch. And the invention uses the milling waste as material to avoid damaging the continuity of road, while the regenerated cold feeding material has high strength.
Description
Technical field
The present invention relates to a kind of road cold-repairing material, relate in particular to a kind of regenerated type road cold-repairing material that asphalt pavement pits such as speedway, town road are repaired fast that is applied to.
Background technology
Along with China's rapid development of economy, problem such as brought the increasing rapidly of the traffic volume, vehicle to maximize, overload is serious is faced with severe tests asphalt concrete pavement, and the maintenance of surface engineering quantity is increasing, and is also more and more higher to the requirement of maintenance technology.The employed inserts of hole groove on road pavement in the middle of the practice of construction is divided into heat material and cold-repairing material at present, and there is following shortcoming in use in the heat material: can not use in (1) colder winter and rainy season; (2) the hole groove will be cleaned out, and drains the water away and dries, and just can use behind the brush sticking layer oil; (3) can not deposit; (4) need experienced operator and special-purpose machinery; (5) less repairing work is got the material amount more than the materials amount, and surplus material cancels, the cost height; (6) repairing finishes needs close traffic a period of time; (7) repairing quality is bad, and cause and repeat to repair, waste material and labour cost, insulation needs to get material more, causes waste.Cold-repairing material is to use more hole, a kind of road surface groove inserts at present, but existing cold-repairing material exists following shortcoming in use: (1) all is to adopt new building stones, new pitch to dash with fluid infusion (cold repairing additive) more according to a certain ratio to mix and stir and form, and cost is higher; (2) can only be used to repair 2m
2The hole groove of following area; (3) repairing quality is bad, causes and repeats to repair waste material and labour cost; (4) find that in use the intact later intensity of pit repairing is low, poor durability, the most of use is no more than three months, individual other uses and will come off in several days, waste great deal of raw materials, increased the engineering quantity of unit in charge of construction, also caused very large economic loss.
Summary of the invention
The object of the present invention is to provide a kind ofly turns waste into wealth, and cost is low, the regenerated type road cold-repairing material that rutting resistance is high.
To achieve these goals, technical program of the present invention lies in having adopted a kind of regenerated type road cold-repairing material, comprise following components in weight percentage content:
Milling material: 56-87%
Cold repairing additive: 0.08%-0.34%
Diesel oil: 0.87%1.6%
All the other are new building stones.
Also can add weight percentage and activate property-modifying additive for the 0.05%-0.26% macromolecule.
Described macromolecule activation property-modifying additive is prepared from by the component of following parts by weight:
Acrylics 1-2 part
Lightweight oils 6.5-11 part.
Described lightweight oils is made up of machine oil of 6-10 part and the kerosene of 0.5-1 part.
Described milling material is bitumeniferous road-surface milling waste material.
Described new building stones can be one or both combinations in basalt, the limestone.
Because regenerated type road cold-repairing material of the present invention is to adopt express highway pavement milling waste material, a spot of new building stones of interpolation, road fluid infusion, diesel oil and macromolecule activation property-modifying additive to heat according to a certain ratio to mix and stir to form, saved great deal of raw materials for country and society, solved also simultaneously in the past that the milling waste material can only abandon as producing rubbish, the pollution problem that causes to environment; Secondly the macromolecule that adds activates property-modifying additive, has solved original milling waste material and has worked as medium pitch owing to the long ageing of asphalt problem that causes service life; Because the main express highway pavement milling waste material that adopts as raw material production, does not destroy the continuous grading on original road surface, the intensity of regeneration type cold-repairing material is very high in addition, and rutting resistance is also than high many of similar cold-repairing material; In addition, the present invention has also solved similar cold-repairing material owing to be that gap gradation can not be repaired the excessive shortcoming of area, and regeneration type cold-repairing material of the present invention can be used for repairing 30m
2All following hole grooves.In addition, the annual weatherproof of cold-repairing material of the present invention; The hole groove only need be done simple process, and a small amount of ponding also can directly be repaired, and has satisfied the requirement of quick repairing when guaranteeing to fill up quality; Stopping of the present invention can be deposited 2 years in the open, packedly deposited more for a long time, and the pot-life is longer; The utilization rate of material is up to 100%, ready access upon use, and surplus material can continue to use next time; Repairing finishes and is open to traffic immediately; Can be used to fill up 30m
2Following hole groove; Cold-repairing material of the present invention can be repaired at any time, keeps road surface Chang Xin, guarantees The coast is clear, reduce traffic accident, reduce and repair number of times, prolong the application life of road greatly, and passed through the experimental examination of Int. of Highway Sciences, Ministry of Communications, met the national regulation requirement.Regenerated type road cold-repairing material of the present invention is applicable to repairs various dissimilar surface courses, as bituminous concrete road, deck paving, vehicle standing, airfield runway, sidewalk, park road, garden place etc.Can round-the-clockly fast, in time repair various pavement diseases, guarantee traffic safety, economical with materials, reduce environment pollution, have obvious social and economic benefits, be worthy of popularization.
Cold-repairing material of the present invention is carried out on-the-spot test, and test result shows: (1) water disbonded test, the finished product material after fully stirring is immersed in the water, and what examine, do not find not wrap fully or peel off gathers materials, and the oil reservoir more than 96% can not dissolve; (2) rolling test, the finished product material that takes a morsel newly formed is made marshal piece according to " highway asphalt and bituminous mixture experiment rules ", be placed on diameter then and be 200 millimeters, aperture and be 25 millimeters round hole screen on erect and roll 20 times, observe its intact situation, be not less than 60%, for qualified.Regenerated type road cold-repairing material of the present invention can reach more than 96%.(3) immersion Marshall Test result shows that the stability of cold-repairing material of the present invention can reach 6.5KN, the qualified 2.5KN that requires.
