By combining several know-how: The binder modification plants, their storage facilities and the mixing and cold mix plants, SAE implements a unique synergy.

Who are we?

Leader in continuous cold mixing and treatment plants

SAE plants have evolved alongside road techniques since the early 60's. Our facilities have taken part in the construction of most of French infrastructures (roads, highways, airports, etc.) as well as in others countries on 5 continents.

For years, quality, precision, process and reliability have been the highlights of our savoir-faire. 

Manufacturing of granular materials or their continuous treatment is the most economical solution on the market; cold techniques with hydraulic binders, hydrocarbonated in the form of emulsion for instance, are sustainable and environment-friendly solutions, caracterized by a low carbon footprint.

Natural resources increasing scarcity and the ensueing extra charge make recycling and material valorization the number one priority of construction trades (roads, dams, airports strips, pipelines, etc.) and quarries. 

SAE continuous cold mix plants can answer every requirements, from the production of graded aggregates to the most complex dense cold-mix asphalt or local products treatment and valorization.
