METHOD OF PRODUCING OF UNSUPPORTED TAPE ROAD CONSTRUCTION MATERIAL Russian patent published in 2011 - IPC B32B11/00 D06N5/00 E04B1/62 

FIELD: construction.

SUBSTANCE: method consists in formation of layer from liquefied composition on the basis of bitumen and thermoplastic elastomer, which is realised at least in three stages. At the first stage and at least at the second stage, onto the first tape substrate and accordingly the second tape substrate, processed with silicon anti-adhesive composition, mastic on the basis of bitumen and thermoplastic elastomer is applied. If mastic temperature is 100-190 deg.C, a fixed layer of mastic is formed on each substrate with thickness making around 1/(n-1) of target product thickness, where "n" - number of layer formation stages. At least at the third stage of layer formation each formed layer of mastic is cooled, released from substrate, one layer is applied onto another, and under pressure and temperature of mastic softening, applied layers are thermally glued and evened along thickness to form summary layer of mastic calibrated by thickness, which is cooled and calibrated in width, corresponding to specified width of target product.

EFFECT: material may be used in construction and in repair of motor roads.
