FIELD: road building. SUBSTANCE: proposed material10 has microstructured return-deflecting member 11 with large number of members in form of cube angles projecting from first side 26 of base which is connected with sealing member 24. Material 10 can be made with possibility of elongation up to 3% with minimum distortion of cube angle members and change between normal state at which microstructured member 11 is curved and really parallel to sealing member 24 and compressed state at which microstructured member 11 is curved to arc and sealing member 24 is really flat. Method comes to delivery of microstructured member 11 and sealing member 24 at equal speed to prevent stretching of sealing member 24 and providing pointing of cube angle members towards sealing member 24 and fastening of first side 26 of base and sealing member 24 to each other to form closed cells 17, each containing curved microstructure member 11. EFFECT: improved service characteristics of separating strips. 6 cl, 1 tbl, 4 dwg, 2 ex
