Application bitumen Emulsion

Sticky bitumen emulsions are cold. Therefore, using them risks warehouse and distribution costs can be avoided in hot conditions. But that's fine layer aggregates create the appearance of breaking the water (emulsion), which should be done well disposed to compaction. If the film
Thin water disposal is done easily.


In construction, the use of bitumen emulsions is as follows:
- Diffusion and surface coating
- Asphalt surface
- Construction of asphalt concrete
- The base and sub-base layers
Diffusion coating and surface coating:
To perform intrusive and plated surface coating layers, bitumen emulsion is easier and safer than conventional liquid bitumen. Liquid bitumen (plated surface and penetrating) net bitumen (plated surface), as in the two cases not being brought special water repellency after breaking the emulsion forms, and the last of the hot liquid bitumen pointless and contrary to the risk of harmful solvents trapped no.
Asphalt surface:
For the implementation of the asphalt surface, the use of its emulsions (cationic emulsion particular) is easier and safer than conventional liquid it. In fact, the use of cationic emulsions, reduces the problem areas are cold and wet. To stabilize the emulsion need to slow evaporation of the solvent is not volatile. Stick surface is usually due to wet granular materials by the water in emulsion done better. Unlike a hot sticky material in contact with the materials (not hot) water has a tendency to conclude the last point where the interests of acidic emulsions Shand (silica, quartzite) is more pronounced.
Asphalt:
Using a bitumen emulsion asphalt concrete construction is possible but far more difficult to apply the method of the previous scenarios. This requires close cooperation between the manufacturer and the emulsion. Asphalt may have problems that could be things like, partial coating of seeds to break prematurely during mixing, emulsifying loss of flow in the mixer, insufficient formability, insufficient density and lack of adequate stability long-term point.
Layers of foundation and the basis:
In December 1974 the Ministry of Civil France guide for building and applying emulsion layers of thick seals and published these on. Specifications required material characteristics similar to granular materials used in seals warmth is concentrated. Are to be produced in factories.
