Abstract

1343192 Reflectors L EIGENMANN 19 April 1971 [7 April 1970] 26158/71 Heading G2J A reflective material for a roadway surface comprises reflective spheres 10 of uniform diameter, reflective spheres 12 of diameter less than one fifth of the diameter of the first spheres and a matrix material, the first spheres occupying not less than 60 per cent of the total volume of the material, the second spheres occupying 20-24 per cent of this total volume, and the binder connecting the first and second spheres. A third set of spheres of smaller diameter than the second spheres may also be present. The spheres may be of glass.
