Изобретение относитс к строительству и может быть использовано при сооружении дорожных и аэродромных оснований и покрытий.The invention relates to the construction and can be used in the construction of road and airfield foundations and coatings.
Цель изобретени - повышение проч- 5 ности, деформативности, морозостойкости и уменьшение водопоглощени композиции дл устройства оснований и покрытий автомобильных дорог а аэродромов.The purpose of the invention is to increase the strength, deformability, frost resistance and reduce the water absorption of the composition for the installation of foundations and road surfaces of airfields.
Композицию используют следующим образом.The composition is used as follows.
В предварительно разрыхленный грунт внос т последовательно в заданном количестве известь, затем при положительной температуре воздуха и при оптимальной влажности известе- грунтовой смеси в последнюю внос т водорастворимый отход сухой перегонки древесины, так называемую раст воримую смолу (ДРС). Смесь перемешивают при помощи фрезы после введени каждого компонента композиции. Уплотнение готовой композиции осуществл ют спуст 6-10 ч после перемешивани всех компонентов.In the previously loosened soil, lime is successively introduced in a predetermined amount, then, at a positive air temperature and at optimum humidity of the limestone mixture, water-soluble waste from the dry distillation of wood, the so-called soluble resin (DRS), is introduced into the latter. The mixture is mixed using a milling cutter after the introduction of each component of the composition. Compaction of the finished composition is carried out after 6-10 hours after mixing all the components.
Растворима древесна смола, в отличие от водонерастворимых отстойной и газогенераторной древесных смол, вл етс пироконденсатным отходом при сухой перегонке древесины , образуетс в результате разложени углеводной части древесины и находитс в растворенном состо нии сThe soluble wood resin, unlike water-insoluble settling and gas generating wood resins, is a pyro-condensate waste from the dry distillation of wood, is formed as a result of the decomposition of the carbohydrate part of the wood and is in a dissolved state with
Готов т несколько вариантов пре лагаемой композиции. Дл зтого используют лесную пылеватую смесь, содержащую 39% песчаных частиц, 53% пылеватых и 8% глинистых, с чи лом пластичности 7, ДРС пирогенную с объемной массой 1,17 г/см ,содер жащую 73% древесного пека, 14% вод растворимых кислот, 13% масел, 30% влаги, известь негашеную с содержанием СаО + MgO 70%.Several variants of the proposed composition are prepared. For this purpose, a forest silt mixture is used, containing 39% of sand particles, 53% of dust and 8% clay, with plasticity 7, pyroic RS, with a bulk mass of 1.17 g / cm, containing 73% of wood pitch, 14% of water soluble acids, 13% oils, 30% moisture, quicklime with CaO + MgO content 70%.
Примеры количественного соотношени предлагаемой композиции дл устройства оснований и покрытий ав томобильных дорог и аэродромов, а также данные по определению физико механических характеристик компози ции представлены в таблице.Examples of the quantitative ratio of the proposed composition for the arrangement of bases and coatings of automobile roads and airfields, as well as data on the determination of the physicomechanical characteristics of the composition are presented in the table.
Данйые таблицы показывают, что предлагаема композици дл устрой ства оснований и покрытий автомобильных дорог и аэродромов имеет высокие показатели прочности, де- 25 формативности, морозостойкости и обладает низкими значени ми величи ны водопоглощени .These tables show that the proposed composition for the construction of bases and coatings of roads and airfields has high strength, deformability, frost resistance and low water absorption values.
