Description
tt
Изобретение относитс к строительству и может быть использовано пристроительстве автомобильных дорог и аэродромов.The invention relates to the construction and can be used in the construction of roads and airfields.
Известно основание дорожной одежды , включающее подстилающий слой из грунта и размещенный на нем структурообразующий слой из доменного шлака , не менее 30 общего количества которого измельчено до частиц размером не более 0,2 мм 13.The pavement base is known, which includes the underlying layer of soil and a structure-forming layer of blast furnace slag placed on it, at least 30 of the total amount of which is crushed to particles no larger than 0.2 mm 13.
Недостатком такого основани вл етс мала прочность и больша трудоемкость , обусловленна необходимостью дополнительного измельчени доменного ишака непосредственно перез его укладкой в основание дорожной одежды.The disadvantage of such a base is low strength and greater labor intensity, due to the need for additional grinding of the domain donkey directly by re-laying it in the base of the pavement.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс основание дорожной одежды, включающее подстилающий слой из обожженных известн ковых высевок L21.The closest to the invention in technical essence and the achieved result is the base of the pavement, which includes the underlying layer of burnt limestone seedings L21.
Недостатком этого основани вл етс мала прочность и сдвигоустойчивость , обусловленна присутствием в основании пористого инертного материала - щебн .The disadvantage of this base is low strength and shear stability, due to the presence in the base of a porous inert material - rubble.
Цель изобретени - повышение прочпрочности и сдвигоустойчивости основани .The purpose of the invention is to increase the strength and shear stability of the base.
Указанна цель достигаетс тем, что в основании дорожной одежды, включающем подстилающий слой и размещенный на нем структурообразующий слой из обожженных известн ковых высевок, подстилающий слои выполнен из золы уноса гидроудалений.This goal is achieved by the fact that at the base of the pavement, which includes the underlying layer and the structure-forming layer placed on it from burnt limestone, the underlying layer is made of water removal ash.
Устройство предлагаемого основани заключаетс в следующем.The apparatus of the proposed base is as follows.
