Abstract (en)
[origin: EP0215139A1] Renovation of esp. deformed road surfaces, using old asphalt, involves; (a) heating the surface with the old asphalt layer; (b) loosening the hot old asphalt layer and uniformly distributing the particles in it on the width, so that the particles are mixed thoroughly; and (c) consolidating the particles in the renovated layer. Before mixing, the particles are treated with amorphous polyolefins (I) as copolymers of olefins with selected monomers so that the mixed prod. is semi-hard to soft and tends to stick at elevated outside temps., 0.3-0.5 wt.% w.r.t. the old asphalt or ca. 7% of its total binder content are used.
