The range of Colstrong

Colstrong Mega

Wearing course mix featuring a pure or modified bitumen from the Colflex range with high gradation. Colstrong Mega has characteristics that are compatible with heavy and aggressive dynamic stresses.

Colstrong Mix

A mix featuring a highly modified asphalt from the Colflex range and specific additive agents. The Colstrong Mix is very compact and withstands rutting and shearing tensions. Colstrong mix can be used as a base, binder or wearing course.

Percolated Colstrong

This surface mix has an extremely open asphalt matrix through which a cement and resin seal has been percolated. Percolated Colstrong is waterproof and fireproof. It does not need expansion joints. It is an economical alternative to concrete. Percolated Colstrong withstands intense puncturing strain and is particularly suitable for zones subjected to static loads, including inside buildings.
