Hot blast leveled heating remixing locomotive
Technical field
The invention belongs to highway engineering machine technical field, specifically a kind of hot blast leveled heating remixing locomotive.
Background technology
Flexible pavement is after Long-Time Service, and can produce the defect such as rut, depression, these will speed up pavement damage, and affect traffic safety.Heat reclaimation technology in site for asphalt surface can be summarized as: first heat defective flexible pavement by preheating locomotive, after pitch is heated and melts, namely reach uniform temperature road surface softening after, then by the in addition milling of milling locomotive.Softening road surface makes flexible pavement change into material Gansu Province state of loose accumulation by original compaction state under less milling active force.The old asphalt mixture gone out because of milling does not change grating, still while adding new material and other additive, the bituminous mixture of mixing can be heated, after stirring further at a certain temperature through row again, to be paved pressing by equipment such as pavers again, form qualified new road surface.
In practice, the pavement quality adopting the method to repair is unstable, does not reach acceptance requirement.Its main cause is: use some preheating locomotives by after road-surface heating to uniform temperature, dug and form the old asphalt mixture of loose depos-its by the milling machine turnning and milling of closelying follow.Because the remixing stage needs to add new bituminous mixture, new bituminous mixture need press from both sides self-unloading tar-spraying car between milling locomotive and remixing locomotive, delivered by it and new bituminous mixture unloaded in the hopper of remixing locomotive, so just make milling locomotive to remixing locomotive from a distance, after making old asphalt mixture and milling, road surface is exposed in air, can not get heating.Therefore before the stirring of remixing locomotive, set up a heater, and sub-material spiral was set before heater divides device and make bituminous mixture obtain larger heating surface (area) (HS.Like this, make the temperature of old asphalt mixture obtain certain raising, but having strong wind and the construction of windy area, because the temperature difference makes heat energy convection action greatly strengthen, make material scatter and disappear a large amount of heat energy further.This just makes heater need to provide most heating power, and lengthens heater, causes the mobility extreme difference of remixing locomotive, and and then affects efficiency of construction and quality.Be exactly briefly do not reach temperature before good stirring after the mixing of new old asphalt mixture, and produce demixing temperature, temperature is even not, the pavement quality of the new paving of final impact.How to make the old asphalt mixture after milling in the remixing stage while the new bituminous mixture of interpolation, heated fully, again stir out stable, the bituminous mixture reaching quality requirement is a major issue.
