Emulsion-bound sand and gravel

What is a emulsion Mixing Plant?

A emulsion mixing plant is an industrial facility, whether fixed or mobile, designed to produce a road material called "emulsion mix." This material consists of aggregates (gravel) mixed with a bitumen emulsion, all cold, without prior heating of the components.

Composition of the emulsion aggregate

• Aggregates of various sizes (e.g., 0/2, 0/4, 4/6, 6/10, 10/14)

• Bitumen emulsion (mixture of water, bitumen, flux, acid, and emulsifier)

• Water is sometimes added to adjust the consistency

Plant Operation

• Precise metering of aggregates using pre-batchers

• Metering of bitumen emulsion and water using metering pumps

• Homogeneous mixing in a cold mixer (horizontal axis or other)

• Temporary storage of the emulsion in tanks

• Automated control and supervision to ensure the quality and traceability of the mix

Plant Types

• Stationary plants: suitable for producing large quantities on a permanent site

• Mobile or compact plants: easily transportable, ideal for remote or short-term projects, with outputs of 80 to 700 t/h depending on the model

Applications of emulsion-mixed aggregate

• Pavement maintenance (reprofiling, reinforcement, new road base)

• Rehabilitation of deformed pavements

• Work on roads with low to medium traffic, particularly in rural areas or on sites where the supply of hot mix is ​​difficult

Advantages of emulsion-mixed aggregate

• Cold use, therefore energy savings and reduced CO₂ emissions

• Adaptability to subgrade deformations

• Good resistance to rutting and cracking

• Possibility of storage and transport over short distances

• Flexible application, both with a grader and a paver

The emulsion batching plant is a key tool for the cold production of high-performance road materials, particularly suited to the maintenance, rehabilitation and creation of roadways in various contexts, while offering economic, ecological and technical advantages.
