Epoxy asphalt concrete due to good with steel plate following, self-strength is high, thinning pave-load layer can reduce deadweight, it has the performances such as outstanding durable, resistance to chemical attack, Rut resistance simultaneously.But because epoxy asphalt mixture match ratio adopts close-graded type, void content control to cause within 3% bituminous epoxy concrete construct shallow, skid resistance is poor, and two-layer equation bituminous epoxy concrete structure is mated formation that cost is high, maintenance difficult, curing time are long generally needs maintenance about 30 days could open to traffic.
Epoxy asphalt concrete composite construction refers to epoxy asphalt concrete+modified asphalt concrete structure (abbreviation composite construction), the cost of asphalt concrete is then much cheap relative to epoxy asphalt concrete, easy to maintenance, construction technology is simple, but poor with steel plate following, intensity is low, should not as bottom paving structure, therefore China's Steel Bridge adopts pavement material to be composite construction.Conventional composite construction and paving method still follow traditional method: brush bonding oil need maintenance 2-3 days after having laid first floor epoxy asphalt concrete bottom after, then paved surface Rotating fields after maintenance 1-2 days.Above-mentioned way not only work consuming is time-consuming, increases construction period and operating expenses, and get half the result with twice the effort, effect runs counter to desire, its main cause is:
1, epoxy asphalt concrete performance is different from other bituminous concrete completely, needs the long period of about about 30 days to carry out the process of heat cure chemical reaction, could solidify gradually and reach design strength.
2, in its solidify reaction process, also need a metastable temperature environment, and temperature is higher, reaction is faster, intensity is higher, and maintenance and brushing bond in the 5-7 days times of oil after conventional primer epoxy asphalt concrete is laid, bottom temperature of mating formation declines, and slowly, intensity reduces, adds curing time in solidification.
3, after bottom is mated formation in several days, again carry out secondary when epoxy asphalt concrete does not also reach intensity and mat formation, the main equipment such as paver, road roller can cause larger damage to substructure.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of paving method of Steel Bridge composite construction, the method overcomes the defect that existing traditional Steel Bridge epoxy asphalt concrete composite construction is mated formation, the effect reach simple, fast, good, economizing and object.
The object of the present invention is achieved like this:
A paving method for Steel Bridge composite construction, comprises the following steps:
Step 1, by steel bridge deck derusting by sandblasting, rust prevention by applying liquid material paint;
Step 2, at steel bridge deck external coating bituminous epoxy tack coat, epoxy asphalt concrete of then mating formation, as primer of mating formation, the bottom and compacting is mated formation;
Step 3, in 2-6 hour that terminates in step 2, mat formation primer temperature 20-50 DEG C time, carry out that surface layer modified asphalt is concrete to pave and roll.
The paving method of a kind of Steel Bridge composite construction of the present invention, is characterized in that: the epoxy asphalt concrete of described bottom, its bitumen aggregate ratio oil content is 7%-9%.
The paving method of a kind of Steel Bridge composite construction of the present invention, is characterized in that: after completing steps 2, and interim lane plate can be laid in the haul track of carrying out surface layer structure laying.
Compared with prior art, the invention has the beneficial effects as follows:
1, the paving method of a kind of Steel Bridge composite construction of the present invention, compared with existing bridge floor composite construction paving method, can reduce the bonding oil of nearly half, under the prerequisite of quality that fully ensures to mat formation, significantly reduce cost; Not only simplify working programme but also decrease time of middle extraordinary maintenance.
2, the paving method of a kind of Steel Bridge composite construction of the present invention, bottom epoxy asphalt concrete is when just complete (2-6 hour), temperature are in 20-50 degree left and right for final pressure, directly carry out that surface layer modified asphalt is concrete to pave and roll, the surface of bottom epoxy asphalt concrete still has epoxy resin and matrix pitch can for combining with surface material and carrying out synchronous curing reaction; And interval time of mating formation between bottom and surface layer is shorter, less on the curing reaction impact of substructure; Combination between two-layer is also better; By the timely covering of surface layer hard pitch, the reaction of bottom curable epoxide is accelerated, and be combined better with steel facing and surface layer structure, intensity is higher, and quality is more excellent, more remarkable effect.
3, the paving method of a kind of Steel Bridge composite construction of the present invention, after bottom epoxy asphalt concrete is mated formation, do not need middle extraordinary maintenance, therefore retardation of curing is caused to react after avoiding the cooling of bottom epoxy asphalt concrete, the epoxy asphalt concrete of bottom obtains the hard pitch covering of surface layer in time simultaneously, thus accelerate solidify reaction process, therefore make the normal pass time advance to about 3 days from about 30 days, improve economic benefit and social benefit.
Detailed description of the invention
The present invention relates to a kind of paving method of Steel Bridge composite construction, the described primer for deck paving is epoxy asphalt concrete, and the surface material of mating formation is modified asphalt concrete.
The paving method step of a kind of Steel Bridge of the present invention composite construction is as follows:
Step 1, by steel bridge deck derusting by sandblasting, rust prevention by applying liquid material paint;
Step 2, at steel bridge deck external coating bituminous epoxy tack coat, epoxy asphalt concrete of then mating formation, as primer of mating formation, the bottom and compacting is mated formation;
Step 3, in 2-6 hour that terminates in step 2, mat formation primer temperature 20-50 DEG C time, carry out that surface layer modified asphalt is concrete to pave and roll;
Preferably, the epoxy asphalt concrete of described bottom, its bitumen aggregate ratio oil content is 7%-9%.
Preferably, after completing bottom epoxy asphalt concrete of mating formation, also should can lay interim lane plate on the haul track of carrying out surface layer structure laying, prevent from polluting substructure and destroying.
Operating principle: after laying bottom epoxy asphalt concrete according to a conventional method, according to different material sources and performance indications, bottom mated formation and tool some strength (because bottom temperature at the end of final pressure just of mating formation is still higher, epoxy asphalt concrete intensity rises very fast) and temperature conditions, generally in 2-6 hour, namely carry out paving and rolling of surface layer asphalt concrete, do not need to carry out middle extraordinary maintenance and spread bonding oil on bottom epoxy asphalt concrete, main cause is: because bottom epoxy asphalt concrete is just complete in final pressure, temperature surface about 20 DEG C time still has epoxy resin and matrix pitch can supply combine with surface material and carry out synchronous curing reaction, and interval time of mating formation between bottom and surface layer is shorter, less on the curing reaction impact of substructure, combination between two-layer is also better, through long term test with detect discovery on the spot, by the timely covering of surface layer hard pitch, the reaction of bottom curable epoxide is accelerated, and be combined better with steel facing and surface layer structure, intensity is higher, and quality is more excellent, more remarkable effect.
