Description
Technical field
The invention belongs to bituminous highway conservation technology fields, and in particular to a kind of modification coating for highway bridge floor
Construction technology.
Background technique
The effect of deck paving is that protection floorings prevent wheel or the direct wearing course of crawler belt, and girder is protected to invade from rainwater
Erosion, and the load so as to dispersing wheel.Common deck paving has cement concrete, two kinds of shapes of mating formation of bituminous concrete
Formula.On the bridge floor of water layer in the air, also has and to be mated formation using water-proof concrete.
Summary of the invention
A kind of modification for highway bridge floor is provided the purpose of the present invention is overcome the deficiencies in the prior art to cover
The construction technology of layer, the road surface of the construction technology can repair the disease on former road surface using cold mixing cold-application thin overlay, restore road surface
Original function makes road surface take on an entirely new look, and is a kind of environmental protection and energy saving construction technology.
In order to achieve the above object, the present invention adopts the following technical scheme:
The present invention provides a kind of construction technology of modification coating for highway bridge floor, it the following steps are included:
(1) former pavement disease processing；
(2) sticking layer oil spread is constructed；
(3) there is first layer the micro-surface area cover of water-proof binding function to construct；
(4) there is the second layer micro-surface area cover of antiskid function to construct.
According to the construction technology of the above-mentioned modification coating for highway bridge floor, the original pavement disease processing includes
Following steps:
A. finish-milling digs, cleans: using finish-milling plane mill off out-of-flatness part to improve surface evenness, is typically employed in highway
In repair and large range of old pavement destroys loose portions, using sweeper or manually leave the cleaning of milling material；Inspection
Each milling scored surface is looked into, when adjacent two milling faces generation occurs greater than 5mm faulting of slab ends, to carry out milling plucking repairing again, and right
The defect of milling scored surface is handled in time；
B. it the repairing of disease: is repaired in strict accordance with the standard requirements of " highway cement concrete pavement maintenance technology specification "
It mends；
C. it cleans crack: using air compressor machine by the disintegrating slag and crack two sides at least 10cm range in slot in the crack on road surface
Interior dust thorough cleaning is clean；The direct filling of notch and fill slot or right >=crack 10mm either to the crack 3~10mm
Seam keeps the cleaning and drying in crack in the gap of crack and the dust of slotted wall is blown off with hair dryer, thoroughly removes clean.
According to the construction technology of the above-mentioned modification coating for highway bridge floor, the sticking layer oil spread construction party
Method: the thin bitumen layer of bonding between pitch and former road surface and spread should thoroughly clean milling scored surface in work progress, use
Surface is floated ash and blown off by air compressor machine, blower, removes wash cement laitance, it is ensured that milling exposed surface is clean, dry；It is dripped using profession
Green distribution vehicle carries out sprinkling sticking layer oil to milling scored surface, and spread quantity is in 0.5kg/ ㎡~0.7kg/ ㎡.
According to the construction technology of the above-mentioned modification coating for highway bridge floor, step (3) first layer micro-surface area cover
Face through traffic bound for 24 hours after, then carry out step (4) second layer micro-surface area cover construction.
