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
Bituminous paving by long-term use after, the defect such as rut, depression can be produced, these will accelerate pavement damage, and affect traffic safety.Heat reclaimation technology in site for asphalt surface can be summarized as: first heating defective bituminous paving by preheating locomotive, Colophonium is heated after thawing, i.e. reaches after uniform temperature road surface softens, then by the in addition milling of milling locomotive.The road surface softened makes bituminous paving be changed 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 asphalt of mixing can be reheated through row, after stirring the most further, paved pressing by equipment such as pavers again, form qualified new road surface.
In practice, the pavement quality using the method to repair is unstable, does not reaches acceptance requirement.It main reason is that: uses some preheating locomotives by after road-surface heating to uniform temperature, is dug and formed the old asphalt mixture of loosely-packed by the milling machine turnning and milling closelyed follow.Owing to the remixing stage needs to add new asphalt, new asphalt need to press from both sides self-unloading tar-spraying car between milling locomotive and remixing locomotive, delivered by it and new asphalt unloaded to the hopper of remixing locomotive, thus 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 asphalt obtain larger heating area.So, make the temperature of old asphalt mixture obtain certain raising, but if having strong wind and windy area construction, owing to the temperature difference makes heat energy convection action be greatly enhanced, make material scatter and disappear substantial amounts 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.Being exactly briefly not reach temperature before good stirring after new old asphalt mixture mixes, and produce demixing temperature, temperature is uniform not, the new pavement quality spread of final impact.How to make the old asphalt mixture after milling in the remixing stage while adding new asphalt, sufficiently heated, again stir out stable, the asphalt reaching prescription is a major issue.
