Description
(54) СПОСОБ СТРОИТЕЛЬСТВА НЕЖЕСТКОГО ДОРОЖНОГО ПОКРЫТИЯ(54) METHOD FOR CONSTRUCTION OF NON-RIGID ROAD COVER
17-40%. Затем по несущему слою производ т розлив, например, поливомоечной машиной 2-5%-ного водного раствора смачивател , например алкилсульфата, из расчета 0,5-2,0 л/м, после чего по поверхности несущего сло распредел ют битумный щлам, например, с помощью прицепного или самоходного распределител РД-902 с регулируемой высотой выходной щели. Битумный щлам укладывают в количестве 20- 50 кг/м покрыти в зависимости от толщины несущего сло и его пустотности, равн ющейс 17-40%. Свежеуложенную полосу ограждают от наезда транспортных средств. Движение транспорта открывают после подсыхани битумного щлама в зависимости от погоды спуст 3-8 ч от начала укладки.17-40%. Then, a pouring layer is produced, for example, by a watering machine of a 2-5% aqueous solution of a wetting agent, for example, alkyl sulfate, at a rate of 0.5-2.0 l / m, after which the bituminous slits are distributed on the surface of the base layer, for example , with the help of a trailed or self-propelled distributor RD-902 with adjustable height of the exit slit. The bituminous slit is laid in an amount of 20-50 kg / m of coating, depending on the thickness of the base layer and its hollowness, equal to 17-40%. The freshly laid strip protects against hitting vehicles. Movement of transport is opened after the bituminous schlama has dried, depending on the weather, 3-8 hours after the start of laying.
Таким образом, обработка перед пропиткой битумным щламом несущего сло из черного щебн водным раствором смачивател повышает физико-механические свойства дорожного покрыти , в частности усталостную прочность и модуль упругости, что позвол ет в конечном счете пропускать поThus, the treatment before impregnation of the black crushed stone with an aqueous solution of a wetting agent with a bituminous slurry improves the physico-mechanical properties of the road surface, in particular, fatigue strength and elastic modulus, which ultimately allows
дороге более т жело нагруженные автомобили и увеличивает срок службы дорожного покрыти .the road has more heavy loaded cars and increases the life of the road surface.
