2.The principle and characteristics of macadam synchronous seal technology
3.The role of synchronous seal technology
3.2 Increased pavement strength
After the completion of the grassroots seal processing base will increase a friction resistance and adhesive force, the rigid bond
between transition, provide support to ensure that the surface layer of soil, grass, cushion, can together to resist the load, so
that the overall strength of the road increases.
3.3 Waterproof penetration
In addition to increasing the strength, the quality of asphalt concrete in construction, stone strength, impact factors, size is
also an important proportion, mixing, paving, rolling temperature, time will affect the quality of asphalt. Especially the
precipitation area pavement often appear serious water seepage, thus adding gravel under seal is very necessary.
4 Introduction of construction technology of macadam synchronous seal
4.1 Heating transportation
In this project, the traffic of the construction section should be controlled first, and the surface of the highway on the
construction site should be deeply cleaned,The heating temperature and dosage of asphalt binder should be strictly controlled，To
ensure that it can deliver the materials to the construction site at the appointed time.
