Изобретение относитс к области дорожного строительства.The invention relates to the field of road construction.
Известен способ возведени дорожной одежды, включающий срезку верхнего сло грунта, его разрыхление, перемешивание с различными в жущими материалами и уплотнение полученной смеси ij . There is a method of erecting pavement, including cutting the top layer of soil, loosening it, mixing it with various stinging materials and compacting the resulting mixture ij.
Недостаток способа - низка износостойкость дорожной одежды. Наиболее близким техническим решением к предлагаемому вл етс способ возведени дорожной одежды, включающий срезку верхнего сло грунта основани , обжиг поверхности нижележащего сло грунта, разрыхление срезанного грунта, укладку его на обожженную поверхность с последующей тепЛовой обработкой и уплотнением 2 . Недостатком этого способа вл етс быстры износ покрыти за истирани и пылеватости поверхности, а также повышенна трещиноватость в местах плавлени грунта.The disadvantage of this method is low wear resistance of the pavement. The closest technical solution to the present invention is a method of erecting pavement, including cutting the upper layer of the base soil, burning the surface of the underlying soil layer, loosening the cut soil, laying it on the burned surface, followed by heat treatment and compaction 2. The disadvantage of this method is fast wear of the coating due to abrasion and dustiness of the surface, as well as increased fracturing at the ground melting points.
Цель изобретени - повышение износоустойчивости дорожной одежды. Достигаетс это тем, что перед укладкой разрыхленного грунта в него ввод т битум и перемешивают полученную смесь, а последующую тепловуюThe purpose of the invention is to increase the durability of the pavement. This is achieved by the fact that before laying the loosened soil, bitumen is introduced into it and the resulting mixture is stirred, and the subsequent thermal
обработку смеси осуществл ют при температуре, не превышающей TefOTepaтуру воспламенени битума. Перед введением в разрыхленный грунт битум подогревают до жидкотекучего состо ни . The mixture is processed at a temperature not exceeding the ignition temperature of the bitumen. Before being introduced into the loosened soil, the bitumen is heated to a fluid state.
Способ осуществл ют следующим образом .The method is carried out as follows.
Верхний слор грунта срезают на заданную глубину, например, фрезерованием . Затем пламенем, создаваемым при сжигании топлива в камере сгорани , подвергают обжигу поверхность среза грунта. В непрерывно укладываемый Top soil soil is cut to a given depth, for example, by milling. Then the flame created by burning fuel in the combustion chamber, is subjected to firing the surface of the cut of the soil. In continuously stacked
5 взрыхленный слой грунта, подвергающийс тепловой обработке газами сжигаемого топлива, непрерывно ввод т св зующий материал - битум и производ т . уплотнение полученной смеси. 5, the loosened layer of soil, subjected to heat treatment with gases of combustible fuel, is continuously injected with a binder material — bitumen and produced. compaction of the mixture.
