Abstract
A microwave preventive maintenance device for asphalt pavements comprises a vehicle body provided with a microwave heater, wherein a road roller is hung or suspended behind the tail of the vehicle body, or a road roller is followed. The construction process of the microwave preventive maintenance equipment for the asphalt pavement comprises the following steps: 1. surveying the road by using asphalt road surveying equipment, and determining a road section with potential diseases and a road section needing preventive maintenance; 2. sealing the road and cleaning the surface of the preventive maintenance road section; 3. presetting the heating depth of the pavement, preliminarily setting the running speed of a vehicle body, heating the asphalt pavement to be soft within a preset temperature range, and compacting the pavement through a road roller; 4. after the construction is finished, the road surface is cooled to about 30-40 ℃, and then the traffic is opened. The invention has simple and reasonable structure, high maintenance efficiency and low cost, can carry out protective maintenance measures when the road surface has slight damage and disease signs, and can prevent the deepening and the expansion of the damage of the surface of the asphalt road.
Description
Technical field
The present invention relates to a kind of road-maintaining truck, particularly a kind of Asphalt Pavement Damage is produced the maintenance of equipment in early stage and utilizes the maintenance construction technology of this equipment, belong to the innovative technology in bituminous pavement preventive maintenance field.
Background technology
Present bituminous highway maintenance measure is more serious hole groove to occur at flexible pavement, rut, be full of cracks, when gathering around diseases such as bag, just maintenance is repaired on the disease road surface, reduce the whole service life of road, and influence flat temperature of being open to traffic of road surface, and existing preventive maintenance technology has slurry seal, crushed stone sealing, thin hot mixed asphaltic concrete overlay, the vaporific seal of the cementation of fissures (or joint seal), asphalt-regenerating method etc. all is the remedial measure when having had disease to occur on the road surface, when large-area surface course disease appears in whole highway section, need by the road pavement milling, seal, overhaul measures such as cover promote road quality, and it is big that it repairs maintenance costs.Just carry out protectiveness maintenance measure in the time of if can slight breakage occurring on the road surface, just can prevent that further expansion of small disease is reflected to road surfaces, makes asphalt roads remain at serviceable condition with the disease sign.And present preventive maintenance equipment can not carry out quickness and high efficiency restoration and protection cheaply to pre-infringement road surface.
Our company discloses a kind of heating using microwave road surface combined maintenance truck in China Patent No. ZL200620054141.2, comprise headstock, chassis, wheel and drive unit thereof, wherein be equiped with electric supply installation, power supply change-over device, pitch material microwave heating system, asphalt pavement microwave heater, motion drive unit, road roller, mulseal sprinkling system, electrical control system, cooling system, hydraulic system on the chassis.Owing to adopt pitch material microwave heating system to add hot asphalt mixture, asphalt pavement microwave heater heating road surface, the pitch sprinkling system is sprayed mulseal, the road roller road pavement is carried out the structure of compacting, jolt ramming, therefore, it not only can save road surface heat time heating time, increase work efficiency, and the pavement patching quality is good.But, can not carry out compacting with being heated to soft flexible pavement consistently because the road roller of this structure is arranged on headstock part.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple and reasonable, maintenance efficient height, cost is low, and can prevent the asphalt pavement microwave preventing maintenance equipment of deepening and enlarging and the construction technology of asphalt roads surface damage, to overcome weak point of the prior art.
A kind of asphalt pavement microwave preventing maintenance equipment by this purpose design comprises the car body that is provided with microwave applicator, and its architectural feature is that roller is pulled or is hung with at the hull back rear, has perhaps followed road roller.
Described microwave applicator is fixedly installed on the middle part or the rear portion of car body bottom surface with motion.
Be provided with elevating mechanism between described car body and the suspension type roller.
A kind of construction technology of asphalt pavement microwave preventing maintenance equipment, its construction technology step is as follows:
1) reconnoitres equipment with asphalt roads and reconnoitre road, determine potential disease highway section and need the preventive maintenance highway section;
2) envelope road, the surface in cleaning preventive maintenance highway section;
3) predetermined road surface heat penetration, initial setting car body travel speed, the heating flexible pavement to predetermined temperature range soft after, by road roller with pavement compaction;
4) according to the prospecting results on road surface and microwave applicator the actual thermal effect that adds of flexible pavement is adjusted the car body travel speed, the heating flexible pavement to predetermined temperature range soft after, by road roller with pavement compaction;
5) construction is finished, and treats that the road surface is cooled to about 30-40 ℃, again open to traffic.
Asphalt roads microwave preventive maintenance equipment of the present invention is owing to have heating soon, heat penetration is big, harmless to the original material of flexible pavement, to the flexible pavement bitumen blowing, loss, pitting groove or decortication, the inner fine crack that occurs can in time be eliminated after adding hot compaction, prevent that asphalt roads surface disease from further expanding road surface to in-house development and internal reflection crack disease, when can greatly reduce rehabilitation cost, improved current ride comfort and the comfortableness of flexible pavement again, flexible pavement microwave preventive maintenance construction technology can reduce the area occupied in maintenance highway section to greatest extent owing to the instant fast effect that heats of microwave, magnitude of traffic flow influence to existing road is little, maintenance efficient height, maintenance quality is good.It is simple and reasonable, work efficiency is high, maintenance asphalt roads cost is low.
