Abstract
The present invention provides a high-strength repair material for asphalt pavement cracks used in the industries such as seepage prevention of building structure surfaces, earth-rock dam roller compacted asphalt concrete impervious face-slabs in hydroelectric engineering, and the like. The high-strength repair material comprises the following components in parts by weight: 1 part of asphalt, 0.02-0.03 part of stearic acid and 0.2-0.5 part of cement. The repair material provided by the present invention can prolong the service life of asphalt pavement after crack repairing.
Description
technical field:
What the present invention relates to is the powerful patching material of asphalt pavement crack preventing blending the industries such as hydroelectric project earth rockfill dam rolled asphalt concrete anti-seepage panel for building structure face.
background technology:
Rolled asphalt concrete road surface is rare does not occur there is the crack that cold crack, reflection crack and ageing of asphalt, wheel load, settlement of subgrade etc. cause in crack.The check crack on road surface not only can be caused in the crack of bituminous concrete pavement, moisture also can be made to infiltrate roadbed, cause roadbed to soften, to the depression of bearing force making road surface.Current, the patching material in crack is more, but still there is defect after repairing.
Current Hydraulic and Hydro-Power Engineering earth rockfill dam rolled asphalt concrete anti-seepage panel crack repairing all adopts hot-melt asphalt, its cohesive force is poor, heat expansion time can produce trickling, to making, the work-ing life after repairing is shorter.
summary of the invention:
The object of the invention is the problem that cohesive force is little, thermal expansion ratio is high existed to solve bituminous concrete crack patching material, providing a kind of asphalt pavement crack that can extend the work-ing life after crack repairing powerful patching material.
The object of the present invention is achieved like this:
The powerful patching material of asphalt pavement crack of the present invention, comprises following component by weight:
Pitch 1,
Stearic acid 0.02 ~ 0.03,
Cement 0.2 ~ 0.5.
The powerful patching material of above-mentioned asphalt pavement crack, comprises following component by weight:
Pitch 1,
Stearic acid 0.03,
Cement 0.2.
Stearic acid cohesive force is strong, asphalt performance can not be changed, cement is stopping composition, prevent pitch from significantly expanding, high temperature resistant, the present invention adds the stearic acid strengthening cohesive force and the cement reducing thermal expansion ratio in hot-melt asphalt, improves the adhesive property of pitch and crack body, and reduces the thermal expansion ratio of patching material.
Bituminous concrete crack patching material of the present invention, can produce in batches in factory, also can prepare at the scene.
The invention solves the technical barrier of the rate that requires that asphalt pavement crack patching material has strong cohesive force simultaneously, weak solarization is swollen and the performance such as more soft, and solve building structure antiseepage facial cleft seam and hydroelectric project earth rockfill dam rolled asphalt concrete anti-seepage panel crack repairing place cohesive force is little and thermal expansion ratio is a large difficult problem, greatly can extend the work-ing life of bituminous pavement after crack repairing.
embodiment:
Embodiment 1:
The powerful patching material of the present embodiment 1 asphalt pavement crack, comprises following component by weight:
Pitch 1,
Stearic acid 0.02,
Cement 0.5.
Embodiment 2:
The powerful patching material of the present embodiment 2 asphalt pavement crack, comprises following component by weight:
Pitch 1,
Stearic acid 0.03,
Cement 0.2.
During crack repairing, can by plant produced finished product (prepare burden in proportion, heat 80 DEG C ~ 120 DEG C mixing finished product) heat, heating and temperature control is at 60 DEG C ~ 65 DEG C, again the bituminous concrete crack patching material of heating is poured onto in clean, dry crack, and strike off, namely complete crack repairing.
During extemporaneous preparation, first asphalt heating to 55 DEG C ~ 65 DEG C, then add stearic acid and cement respectively in proportion, stir and namely make bituminous concrete crack patching material.During crack repairing, the patching material of heating is poured onto in clean, dry crack, and strikes off, namely complete crack repairing.
Above-described embodiment is described further foregoing of the present invention, but this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to above-described embodiment.All technology realized based on foregoing all belong to protection scope of the present invention.
