Abstract (en)
[origin: EP1052334A2] Mobile mixer to be used in train for cold recycling asphalt concrete roadways, of the type comprising bitumen as binding base, where are provided: means to heat said binding material in fluid form at 150/200 DEG C, preferably at about 170 DEG C, and under pressure before the spraying (U2) in said mixing means (P1); means to convey hot and fluid bitumen (B, P2) in a controlled way (P3) with additives (AD) through a static turbo-mixer with opposite vanes (P4), to respective sprayers (P1) associated with: means to inject water, in a controlled way (U2), to said binding material immediately before the spraying, upstream of said sprayers (U3), under such a pressure to prevent the expansion of said added water, in order that at the exit from said spraying means (U3) a spraying of bituminous emulsion is formed with expansion by evaporation of the water particles forming a bituminous material foam that is sprayed into the aggregating material in the mixing/blending, thus mixing and binding with it (P1). <IMAGE>
