Abstract
Изобретение относитс к дорожному строительству и может быть использовано при устройстве дорожных одежд на основе применени неорганического в жущего и минерального заполнител . Целью изобретени вл етс повышение прочности дорожной одежды за счет улучшени пропитки смеси. Способ включает смешение минерального материала с неорганическим в жущим, укладку, увлажнение и уплотнение смеси, в воду перед увлажнением смеси ввод т комплексную добавку - тринатрийфосфат и лигносульфонатный пластификатор в количестве соответственно 0,7-1,5 и 0,8-1,3 % от массы в жущего, в качестве которого используют фосфогипс.The invention relates to road construction and can be used in making pavements based on the use of inorganic in the tonic and mineral aggregate. The aim of the invention is to increase the strength of the pavement by improving the impregnation of the mixture. The method involves mixing the mineral material with an inorganic in the ground, laying, moistening and compacting the mixture; before the mixture is moistened, the complex additive, trisodium phosphate and lignosulfonate plasticizer, is added in an amount of 0.7-1.5 and 0.8-1.3%, respectively from the mass to the slider, as which phosphogypsum is used.
Description
Изобретение относитс к строительству и может быть использовано при возведении дорожных одежд на основе применени неорганического в жущего и минерального заполнител .The invention relates to the construction and can be used in the construction of pavements based on the use of inorganic in the living and mineral aggregate.
Цель изобретени - повьшение прочности дорожной одежды за счет улучшени пропитки смеси.The purpose of the invention is to increase the strength of the pavement by improving the impregnation of the mixture.
Дорожную одежду возвод т следующим , образом.Road clothes were erected as follows.
На уплотнительный грунт вьшоз т минеральный материал (щебень фракции 5-70 мм), перемешивают с неорганическим в жущим - фосфогипсом (25-40% по массе от доли наполнител ) и распредел ют смесь автогрейдером. Перед уплотнением сло смеси толщиной 10-12 см ее увлажн ют путем разлива воды с комплексной добавкой: тринатрийфосфат 0,7-1,5% + лигносульфонатный пластификатор 0,8-1,3% от массы в жущего при водогипсовом отношении 0,2-0,4.Mineral material (crushed stone of fraction 5–70 mm) is mixed onto the compacted soil, mixed with inorganic in the binder — phosphogypsum (25–40% by weight of the filler fraction), and the grader is distributed. Before compaction of a layer of a mixture with a thickness of 10–12 cm, it is moistened by spilling water with a complex additive: trisodium phosphate 0.7–1.5% + lignosulfonate plasticizer 0.8–1.3% by weight of a mixture with a water gypsum ratio of 0.2- 0.4.
Введение комплексной добавки в композиционный состав смеси позвол ет увеличить сроки хранени , необходимые дл проникновени воды на всю глубину сло , способствует увеличению периода формировани структуры фосфогипсо- вого камн , увеличению скорости упрочнени структуры и конечной прочности.The introduction of the complex additive into the composition of the mixture allows an increase in the shelf life required for the penetration of water over the entire depth of the layer, contributes to an increase in the period of formation of the phosphogypsum stone structure, an increase in the structure strengthening rate and the final strength.
