Abstract
Description
Предлагаемое изобретение относится к дорожно-ремонтным работам и может быть использовано при усилении дорожных одежд нежесткого типа.The present invention relates to road repair work and can be used to reinforce non-rigid pavement type.
Известен способ усиления дорожных одежд нежесткого типа методом холодной регенерации, заключающийся в фрезеровании существующего покрытия на одинаковую глубину в поперечном направлении, введении в измельченный материал добавок, перемешивании компонентов, распределении и уплотнении смеси и укладке замыкающего слоя [1, 2]. Недостатком этого способа является перерасход материалов, из-за того что регенерацию существующей дорожной одежды осуществляют на одинаковую глубину по всей ширине проезжей части. При расчете усиления конструкции дорожной одежды согласно ОДН [3] предполагается ее равнопрочность по ширине, в то время как наибольшие нагрузки испытывают грузовые полосы проезжей части. Данный способ является наиболее близким к предлагаемому по техническому решению и достигаемому результату.There is a method of reinforcing pavements of a non-rigid type by cold regeneration, which consists in milling the existing coating to the same depth in the transverse direction, introducing additives into the ground material, mixing the components, distributing and compacting the mixture and laying the closing layer [1, 2]. The disadvantage of this method is the cost overrun of materials, due to the fact that the regeneration of existing pavement is carried out at the same depth over the entire width of the roadway. When calculating the reinforcement of the pavement structure according to ODN [3], it is assumed to be equally stable in width, while the freight lanes of the roadway experience the greatest loads. This method is the closest to the proposed technical solution and the achieved result.
Цель предполагаемого изобретения - снижение материальных затрат.The purpose of the proposed invention is the reduction of material costs.
Поставленная цель достигается тем, что существующее покрытие (осуществляют холодную регенерацию) фрезеруют с обеспечением 3-5%-ного двухскатного поперечного уклона подошвы регенерированного слоя путем установки концов фрезерного барабана на разную глубину рыхления, вводят в измельченный материал добавки, перемешивают компоненты, распределяют и уплотняют смесь и укладывают замыкающий слой.This goal is achieved by the fact that the existing coating (carry out cold regeneration) is milled to provide a 3-5% double slope transverse slope of the sole of the regenerated layer by setting the ends of the milling drum to different depths of loosening, additives are introduced into the crushed material, the components are mixed, distributed and compacted mix and lay the closing layer.
В результате толщина регенерированного слоя уменьшается от кромок проезжей части к оси дороги и расход вяжущего снижается.As a result, the thickness of the regenerated layer decreases from the edges of the carriageway to the axis of the road and the consumption of the binder decreases.
Пример. Обследование существующей дороги показало, что фактический модуль упругости дорожной конструкции на грузовой полосе движения составил 240 МПа, а на скоростной - 280 МПа при требуемом по расчету 290 МПа. Чтобы получить требуемый модуль, достаточно было регенерировать дорожную одежду на глубину 17 см с укладкой поверх регенерированного слоя асфальтобетонного слоя толщиной 5 см. Первый проход стабилизера с шириной обработки 2,5 м при ширине половины проезжей части 3,75 м выполнили по грузовй полосе на глубину 17 см в середине полосы с поперечным уклоном фрезерного барабана 4%. При этом глубина фрезерования составила соответственно 22 см у внешней кромки и 12 см у внутренней кромки. Второй проход выполнили на той же половине проезжей части по скоростной полосе с захватом 1,25 м первой полосы с таким же поперечным уклоном фрезерного барабана. Глубина фрезерования составила соответственно 17 см у стыка и 7 см у осевой кромки. Аналогичные операции выполнили и на второй половине проезжей части. При нормах расхода вспененного битума и цемента по 2,5 % от массы регенерируемого материала их экономия составила по 1,5 кг/м2.Example. Examination of the existing road showed that the actual modulus of elasticity of the road structure in the cargo lane was 240 MPa, and on the high-speed one - 280 MPa with the required calculation of 290 MPa. To obtain the required module, it was enough to regenerate the pavement to a depth of 17 cm with laying on top of the regenerated layer of asphalt concrete layer 5 cm thick. The first pass of the stabilizer with a working width of 2.5 m and a width of half of the carriageway of 3.75 m was carried out along the cargo strip to a depth 17 cm in the middle of the strip with a transverse slope of the milling drum 4%. In this case, the milling depth was respectively 22 cm at the outer edge and 12 cm at the inner edge. The second pass was made in the same half of the carriageway along the high-speed lane with a capture of 1.25 m of the first lane with the same transverse slope of the milling drum. The milling depth was respectively 17 cm at the joint and 7 cm at the axial edge. Similar operations were performed on the second half of the carriageway. When the consumption rates of foamed bitumen and cement are 2.5% by weight of the regenerated material, their savings amounted to 1.5 kg / m 2 .
