METHOD FOR BUILDING ROAD PAVEMENT

摘要

FIELD: road-building technology. SUBSTANCE: according to motor-road building method, slag-type double-layer asphalt-concrete pavement is reinforced with geoscreen which is preliminarily treated by waste from coke-chemical production process. Application of aforesaid procedure results in doing away with operation of pouring binding material to lower layer of pavement before arrangement of upper layer of pavement. Produced is pavement which is shear- and cracking-resistant, because geoscreen takes shear forces at temperatures abovezero centigrade and dampens microcracks from lower courses occurring at belowzero temperatures. Application of by-products and waste from industry allows for reducing cost of realizing aforesaid pavement-building method. Slag-type asphalt-concrete pavement acquires strength and shear-resistant properties just from moment of its building. EFFECT: higher efficiency. 2 tbl
