Abstract
Mastic asphalt mixture for road, building and industrial construction, which contains 0.1 to 2% by weight of silica. For example, a precipitated silica, a precipitated and spray dried, or a pyrogenously produced silica may be used as a synthetic silicic acid. The content of synthetic silica produces an essentially higher degree of hardness in the finished mastic asphalt layer.
