Description
（One）Technical field
The invention belongs to road construction field of mechanical technique, more particularly to a kind of sealing spread equipment and spread method.
（Two）Background technology
Technology mainly has synchronous surface dressing, mist sealing and the sealing of mist containing sand etc. at the table of road surface at present.
During road construction, bituminous paving passes through synchronous surface dressing, can have better anti-skidding and infiltration
Energy.Synchronous pavement surface dressing is that rubble and binding material are synchronized paving to be sprinkled upon on road surface, and list is formed by natural traffic bound
Layer asphalt macadam wearing course is used as layer at the table of road surface.
Road surface is because increase, the overload transportation etc. of vehicle flowrate will appear track, gather around the diseases such as packet, cracking, surface be smooth, pitch
The disease on road surface is mostly caused by surface is seeped water.Existing mist sealing covers be sprayed on asphalt surface course it is a thin layer of, high
Infiltrative emulsified asphalt forms one layer of strict waterproof layer and closes road surface, is a kind of direct, economical, effectively preventative
Maintenance construction measure acts on prolonging service life of pavement apparent.
The sealing of mist containing sand is a kind of novel asphalt pavement of highway maintenance technology, and technique is that will have good infiltration
