Art field.
Background technology
Bituminous paving by long-term use after, the defects such as rut, depression can be produced, these will accelerate pavement damage, and influence
Traffic safety.Heat reclaimation technology in site for asphalt surface can be summarized as：First defective bituminous paving is carried out by preheating locomotive
Heating, after the heated thawing of pitch, that is, reaches after the softening of certain temperature road surface, then be subject to milling by milling locomotive.The road surface of softening
Bituminous paving is set to change into material Gansu Province state of loose accumulation by original compaction state under less milling active force.Because of milling
The old asphalt mixture gone out does not change level and matched somebody with somebody, still can be while new material and other additives is added, to the pitch of mixing
Compound is reheated through row, after further stirring at a certain temperature, then is paved pressings by equipment such as pavers, forms conjunction
The new road surface of lattice.
In practice of construction, the pavement quality repaired using the method is unstable, does not reach acceptance requirement.Its main cause
It is：Using some preheating locomotives by after road-surface heating to certain temperature, by immediately following milling machine turnning and milling dig and form loose heap
Long-pending old asphalt mixture.Because the remixing stage needs to add new asphalt, new pitch compound need to be in milling locomotive
Self-unloading tar-spraying car is pressed from both sides between remixing locomotive, is delivered by it and is unloaded new asphalt into the hopper of remixing locomotive, this
Sample just makes milling locomotive from a distance, road surface after old asphalt mixture and milling is exposed in air to remixing locomotive,
It cannot heat.Therefore a heater is set up before the stirring of remixing locomotive, and the setting sub-material spiral before heater
Dividing device makes asphalt obtain larger heating area.So, the temperature of old asphalt mixture is made to obtain certain raising,
But if having strong wind and windy area is constructed, because the temperature difference greatly enhances heat energy convection action, further dissipate material
Lose substantial amounts of heat energy.This just makes heater need to provide most heating power, and lengthens heater, causes remixing locomotive
Mobility extreme difference, and and then influence efficiency of construction and quality.It is exactly briefly not reach after new old asphalt mixture is mixed
Temperature before good stirring, and demixing temperature is produced, temperature is not uniform enough, finally influences the pavement quality newly spread.How milling is made
Old asphalt mixture after plane is sufficiently heated, stirred again while new pitch compound is being added in the remixing stage
Go out stabilization, the asphalt for reaching quality requirement is a major issue.
