Изобретение относитс к области дорожного и аэродромного строительства, конкретно к способу приготовлени грунтоцементной смеси.The invention relates to the field of road and airfield construction, specifically to a method for preparing a ground-cement mixture.
Известен способ приготовлени грунтоцементной смеси, включающий перемешивание грунта с цементом и битумом 1.There is a method of preparing a ground-cement mixture, which includes mixing the soil with cement and bitumen 1.
Наиболее близким по технической сущности и достигаемому эффекту к предлагаемому вл етс способ приготовлени грунтоцементной смеси, включающий смещение грунта, щебн , цемента, воды и обработку битумом 2.The closest to the technical essence and the achieved effect to the proposed method is the preparation of ground-cement mixture, including the displacement of soil, rubble, cement, water and processing bitumen 2.
Однако при перемещивании грунта со щебнем, затем с цементом и водой происходит налипание грунта на щебень и его увлажнение, что ухудщает адгезию битума к щебню.However, when moving the soil with rubble, then with cement and water, the soil sticks to the rubble and moistens, which impairs the adhesion of bitumen to rubble.
Цель изобретени - повышение прочностных и деформативных свойств покрыти .The purpose of the invention is to increase the strength and deformation properties of the coating.
Это достигаетс тем, что по предлагаемому способу приготовлени грунтоцементной смеси, преимущественно дл дорожного и аэродромного покрыти , сначала грунт перемещивают с цементом и водой, а затем смещивают со щебнем, предварительно обработанным битумом.This is achieved by the fact that according to the proposed method of preparing a ground-cement mixture, mainly for road and airfield pavement, the ground is first moved with cement and water, and then displaced with rubble, previously treated with bitumen.
Кроме того, щебень перед обработкой битумом подогревают до температуры 80-120°С.In addition, crushed stone before processing with bitumen is heated to a temperature of 80-120 ° C.
Способ приготовлени грунтобетонной смеси заключаетс в дозировании грунта, щебн , цемента, битума и воды и раздельной обработке грунта с цементом и водой,The method of preparing the soil-concrete mixture consists in the dosing of soil, crushed stone, cement, bitumen and water and the separate processing of the soil with cement and water,
а щебн - битумом, с последующим их перемещиванием. Щебень перед смешением с битумом подогревают до 80-120°С. Щебень с размером зерен не более 15 мм и прочностью 400 кг/см и выще перемешивают с битумом в стационарных смесител х принудительного действи , а щебень с размером зерен более 15 мм и прочностью менее 400 кг/см - в смесител х со свободным перемещиванием. Грунт перемещивают с цементом и водой при температуре не ниже 0°С.and rubble - with bitumen, with their subsequent movement. Crushed stone before mixing with bitumen is heated to 80-120 ° C. Crushed stone with a grain size of not more than 15 mm and a strength of 400 kg / cm and more vigorously mixed with bitumen in stationary forced-mixers, and crushed stone with a grain size of more than 15 mm and strength less than 400 kg / cm-in mixers with free movement. The soil is moved with cement and water at a temperature not lower than 0 ° C.
