Abstract
Environmental porous pavement materials are formed by encapsulating inner aggregates with cementitious material, adhesive admixture and sealant compounds. Recycled asphalt and recycled concrete products can be used. A mixing machine produces a homogeneous mix of the paving material by surrounding at least part of an aggregate with a coating liquid.
