Abstract
The present invention relates to bituminous coated materials including a granular fraction and a binder, characterised in that in the granular fraction all or part of the elements are selected from among lightweight, non-absorbent aggregates with a density of less than 1.6 t/m3 and a water absorption coefficient of less than 15%. The invention also relates to the use of light, non-absorbent aggregates with a density of less than 1.6 t/m3 and a water absorption coefficient of 3% to 15% for the production of light bituminous coated materials. The invention further relates to pavements obtained by applying at least one layer of the coated materials according to the invention and to a method for applying a surface course to a surface raised above the ground which includes a step of applying coated materials according to the invention.
