THE UPPER PART OF MULTILAYERERD CONSTRUCTION OF ASPHALT ROADWAY PAVEMENT

摘要

The invention relates to the highway engineering and can be used at construction of motorways, runways of the aerodromes sports grounds, parking places, etc.. The offered roadway pavements are made multilayered, with layers laid on the site. The purpose of the invention is to increase the strength and service life of the upper layers of roadway pavements. On the drawing of fig.1 a multilayered asphalt roadway pavement is shown, which consists of asphalt layers (1, 2) and reinforcing material (3) placed between them. The layer of reinforcing material (3) is executed using rolled heat-and-hydro-insulating material of the MPV-bit-bit type, with the roadbeds (4) of reinforcing material (3) laid perpendicularly to the axial line of the road, their mutual overlapping being not less than 10% of the roadbed width.
