FIELD: construction.
SUBSTANCE: invention is related to the field of construction, in particular to construction of aerodromes in complex geotechnical and severe climate conditions. Aerodrome pavement is made of plates with size of 7x20 m, longitudinal through deformation seam has the shape of equilateral hexagon sides. Plates are reinforced with two welded meshes. Owing to the shape of longitudinal through seam, retaining force of neighboring plates is increased. It makes it possible to increase permissible value of soil base heaving to 40 mm and, accordingly, to increase thickness of irreplaceable heaving soil base at least twice, to reduce thickness of artificial base made of non-heaving material. Application of geotextile of "Dornit" type as anti-silting layer reduces labour intensiveness of its arrangement and improves operation of soil base after is has thawed. Direct support of single-layer hard pavement on artificial base increases flexural rigidity in winter period and reduces uneven deformations of frosty heaving. Negative effect of frost-shattered cracks on longitudinal and transverse joints is avoided. Period is increased between major overhauls of landing strips in aerodromes located in complex geotechnical and severe climate conditions.
EFFECT: reduced labour intensiveness of works performance and improvement of soil base operation after its thaw.
