As pavement material, where porous asphalt are filled with polymer cement paste (rapid hardening cement, blast slag powder, polymer, pigment, admixture etc), LOHASCON has softness of asphalt pavement and hardness of concrete. In other word, LOHASCON is pavement material made of polymer, rapid hardening cement, slag powder, pigment, admixture etc mixed together. It offers solution to the problems for conventional semi-rigid pavement material i.e. extended construction time and increased construction cost caused by retarded hardening...
