Bituminous Mix Design for Pavement – Types, Materials and Properties
The bituminous concrete is a combination of aggregates that is continuously graded from the maximum size which is mainly less than 25mm to the fine filler of size smaller than 0.075mm to make the mix sufficiently impervious. This provides a layer will have acceptable levels of dissipative and elastic properties.
