Abstract
The utility model discloses an apparatus for heating asphalt mixture of asphalt paving road before compacting, comprising a frame, a heating plate and a liquid gas storage tank; the liquid gas storage tank is installed on the frame; the heating plate is levelly arranged at bottom of the frame; lower part of the frame is provided with running wheels. The apparatus is suitable for heating the asphalt rods and asphalt mixture after the asphalt mixture paving construction and before rolling so that the asphalt mixture has enough paving temperature and the lower layer has enough heat binding temperature, thereby ensuring the quality of reclaimed bituminous pavement. The apparatus has simple structure, low cost, convenience and practicality.
Description
Technical field
The utility model relates to a kind of flexible pavement bituminous mixture firing equipment, is the pitch paving concrete pavement bituminous mixture firing equipment before a kind of compacting specifically.
Background technology
Normally will be transported to job site to be paved to the bituminous mixture that proportionings such as pitch, building stones add after the thermal agitation by special-purpose Construction traffic in the large-scale bituminous pavement paving construction commonly used through bituminous mixing plant.Equally in large-scale asphalt surface hot reproduction work progress, employing uses the heater-heating panel of the large-scale in-situ heat regeneration vehicle of flexible pavement to toast to old complaint evil flexible pavement, flexible pavement top layer bituminous mixture makes its fusion, utilize the loose rake device of hydropneumatic combined type on the in-situ heat regeneration vehicle to harrow pine, smash again for it, spray an amount of mulseal regenerative agent, mix the new bituminous mixture of proper proportion then, heating mixes, and compacting again paves.Under two kinds of above-mentioned condition of construction owing to be to descend operation in the open, the former is transported to the job site by Construction traffic with bituminous mixture, the latter is through in-situ heat regeneration vehicle heating, rake pine, smashes, the mulseal regenerative agent that sprays, mix the new bituminous mixture of proper proportion then, because the equipment of the mulseal regenerative agent of heating, rake pine, sprinkling is undertaken by many Construction traffics successively.Bituminous mixture has inevitably lost a large amount of heats in air.At this moment the bituminous mixture that paves after constructing is difficult to realize the more satisfactory temperature of asphalt road interlayer heat bonding.
The utility model content:
The utility model has proposed the preceding pitch paving concrete pavement bituminous mixture firing equipment of a kind of compacting at the problem that prior art exists.Before being used for after bituminous mixture laying construction, rolling flexible pavement and bituminous mixture are heated once more, have enough temperature and lower floors of paving that enough heat bonding temperature are arranged to guarantee bituminous mixture, thereby guarantee the reclaimed bituminous pavement quality.
Pitch paving concrete pavement bituminous mixture firing equipment before a kind of compacting of the utility model comprises framework, heating panel and liquid gas storage tank.Liquid gas storage tank is installed on the framework, and heating panel is horizontally placed on the framework bottom surface, and the framework bottom is provided with road wheel.
Liquid gas storage tank provides combustion gas for the flame gun of heating panel, and heating panel is pressed close to flexible pavement, along with the walking of road wheel, successively pitch paving concrete pavement bituminous mixture is heated.After the heating of road surface, subsequently by the rolling apparatus compacting.
The utility model is simple in structure, with low cost, and convenient and practical.
Description of drawings
Fig. 1 is the pitch paving concrete pavement bituminous mixture firing equipment schematic perspective view before the utility model compacting.
Fig. 2 is the pitch paving concrete pavement bituminous mixture firing equipment elevation before the utility model compacting.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1, 2, the pitch paving concrete pavement bituminous mixture firing equipment before the compacting, by framework 1 and about two heating panels 2 (existing known products) and the liquid gas storage tank 3 on it form.Road wheel 4 is installed for four jiaos in the bottom of framework, and wherein, two road wheels in front are for can turn to roller, and two of back are fixing roller.Liquefied gas flows to flame gun in the heating panel by liquefied gas bottle 3 and liquefied gas pipeline after the distribution drum shunting, form the heat radiation heating function.Sleeve mechanism can adopt dismountable hinge to combine, and can split into a plurality of component fast, and sleeve mechanism is unfavorable for that by original heaviness the characteristics of transporting can be readily solved.Each component after splitting can manually can easily be carried, can free at the construction field (site) easily assembling.
In the asphalt surface hot reproduction repair process, having finished heating and melting to old asphalt pavement, rake pine, having smashed, sprays an amount of mulseal regenerative agent, mix the new bituminous mixture of proper proportion then, the heating mixing, implementation paves.Behind the bituminous mixture laying, pitch paving concrete pavement bituminous mixture firing equipment before the compacting of utilization the utility model carries out the heat radiation baking to the back flexible pavement that paves, above-mentioned heating panel described in the invention is not limited in the heat radiation baking, can use simply with other mode of heatings such as hot air type heating panel and replace, distinct device and mode of heating are to the heat radiation baking of the back flexible pavement that paves, the purpose of its main construction techniques has been to realize the paver ironing heating on road surface afterwards, thereby make the road surface after paving that higher temperature be arranged, the temperature of realizing ideal that helps road surface roadbed and each bituminous mixture interlayer forms heat bonding efficiently, adhesion stress and intensity between the bed of material have been improved, again after rolling, obtain better smooth high-quality flexible pavement with this, prolonged the application life of flexible pavement.
