FIELD: construction.
SUBSTANCE: dam comprises an anti-filtration element in the form of a core from clayey soil, upper and lower side prisms from large fragmental soils, a head wall from non-heaving soil and a road surface on a dam crest traffic area. The material of at least the road surface has a coefficient of solar radiation absorption of at least 0.9. The road surface of the dam crest traffic area is made from asphaltic concrete.
EFFECT: higher reliability of a dam due to prevention of freezing of its core upper part.
