FIELD: construction.
SUBSTANCE: invention relates to road construction and can be used in construction and repair of asphalt concrete pavements of motor roads. Disclosed is a method of laying porous-mastic asphalt concrete, in which old coating is milled using a road cutter, after milling, the obtained coating is cleaned and the milled coating of the bituminous emulsion is milled with the help of an auto-flow oil agitator, one prepares a porous-mastic asphalt-concrete mixture with its subsequent laying. Tack coat is performed at emulsion consumption 0.2–0.3 l/m2, laying is performed by asphalt-spreader with vibration plate off, at that asphalt-spreader tamper bar is used only for 20–30 %. After that, obtained surface is ranked by light roller in 1-2 passes along track, at that, roller should go immediately behind asphalt-spreader machine at minimum permissible distance from it.
EFFECT: increased efficiency of road works, reduced economic costs and possibility of works at negative temperatures.
