  • Patent number: 4309124
    Abstract: A reinforced asphalt layer, consisting of an asphalt-forming mixture of bitumen with mineral particles, in which is embedded a reinforcing network of elongated reinforcing elements which, where they intersect one another, have a connection to one another which at least to a certain degree fixes the cross-bond, in which the reinforcing elements at least locally have a cross-section of maximum linear dimension of the order of the particle size, and a shape such as to exhibit a change of direction longitudinally from location to location of their engagement of the surrounding material of the layer, the arrangement being such that in a finished, rolled asphalt layer the reinforcing elements have adjusted locally to the mineral particles by deformation, on the one hand, and the reinforcing network has largely retained its elasticity, on the other.
