Background technique
Currently, bituminous pavement occupies absolute leading position, domestic highway and each grade road, bridge in China's road
Bituminous pavement form is all made of in the main roads such as face mats formation, airfield runway, urban road.However, with China's road construction
Development, road builds on a large scale throughout the country, and time, the formation of road snow mantle and dark ice seriously threaten road in winter
Traffic safety, it is so very big that constrain the development of carrier, inconvenience is brought to the production and living of people.Therefore, it solves
Ice problem is coagulated in winter road snowfall, reduces Traffic Accident Loss, improves road efficiency of operation, becomes present grey decision system work
Person needs the direction captured.
Existing winter deicing method is mainly using snow dust is passively removed, after snowfall generation, by manually removing the snow, dispensing
The work that clears the snow is realized in deicing salt and snow removal with machine.The passive common fault except snow dust is that it can not complete Snow removing immediately, when
Effect property is poor, and is difficult to solve the solidifying ice problem in road surface after snow removing.And artificial snow removing, effect is poor, low efficiency；Dispense deicing salt operation
It is extensive, it is big to environmental hazard；Machinery, which clears the snow, to consume energy greatly, can not remove in time to high speed at a distance, road pavement is destroyed very big.
To solve passively to remove the various disadvantages of snow dust, the main side that snow dust is increasingly becoming road deicing snow technology is actively removed
To.Active deicing technology mainly has energy supply type and non-power providing type, and energy supply type mainly passes through the pipeline being laid in advance, takes electricity
Heat, the mode of hydro-thermal carry out deicing or snow melting；Non-power providing type mainly reaches deicing effect using storage salt or elastic road surface.It is passing through
Think after crossing prolonged scientific research and application, in the case where considering cost maintenance, action time and using effect, using storage
Salt technology is more reasonable technology, but there are constructional difficulties and long-term effect are bad for the existing anticoagulant ice technology of storage salt
Problem, this is just that the use of people brings inconvenience.
