As revealed In this particular cross-section, quite a few older roadways are smoothed by implementing a thin layer of asphalt concrete to the present portland cement concrete, creating a composite pavement. Mixing of asphalt and mixture is attained in one of quite a few techniques:[fourteen]
Various specialty asphalt concrete mixtures have been designed to meet distinct needs, for instance stone-matrix asphalt, that is built to make sure a robust wearing surface area, or porous asphalt pavements, which might be permeable and allow h2o to drain throughout the pavement for managing storm drinking water.
