Asphalt mixtures are composed of bituminous hydrocarbon binders and a “granular fraction”, i.e. a combination of aggregates of different sizes and characteristics, mixed to obtain an asphalt concrete. Laterlite Expanded Clay LWA, used as a component of the bituminous mixture to replace part of the natural aggregates, significantly improves its technical characteristics.
Depending on the percentage of Expanded Clay aggregate used and the choice of particle size, as well as the optimisation of the binder, these mixtures have characteristics of noise reduction, drainage, high adherence, or lightness.
Asphalt concretes based on Laterlite Expanded Clay lightweight aggregates are hot mixed in conventional asphalt batch mix plants: the absolute quantity of hydrocarbon binder per cubic metre of bituminous concrete, remains the same as that used for traditional bituminous mixes, as well as the manufacturing process, the aggregates being non-adsorbent.
Various types of special asphalt mixes can be produced, as shown below.CONTACT US
