<p>1. Construction materials comprising from 94 to 97 % by weight of mineral aggregats and from 3 to 6 % by weight of polymer, characterized in that said polymer comprises at least 50 % by weight of an ethylene polymer having a molecular weight between 12,000 and 50,000, a density between 0.90 and 0.93 g/cm**3 and a viscosity in the molten state greater than or equal to 34 Pa.s, in admixture with another thermoplastic polymer when said ethylene polymer ist not used alone.</p> |
