Description
Известна асфальтобетонна смесь, содержаща регенерированный асфальтобетон, нанолнители и добавки, из которой получают асфальтобетон низкой водостойкости и прочности . Цель предлагаемого изобретени - повысить степень водостойкости и прочности асфальтобетона . Достигаетс это тем, что в качестве добавки нспользован 5-12%-ный раствор термопластичного полимера на основе производных акриловой или метакриловой кислот, имеющего в своей структуре амидные грунны, в жидком битуме. Асфальтобетонна смесь может содержать указанные компоненты в J/o по весу: регенерированный асфальтобетон 78-91 наполпитель7,8-21 раствор полимера0,3-2,2 В качестве регенерированного асфальтобетона использован асфальтобетон, восстановленный теплорадиациоппым способом npii температуре не выше 150°С. При этом способе не происходит практически окислени битума , что важно дл сохранени стабилизировавшейс структуры битумно-минерального материала, образованной в процессе эксплуатации асфальтобетонного покрыти . В качестве активного полимера может быть использован, например, сополимер бутплакрнлата с метаакриламидом или полиакриламид. Использование раствора активного полимера в жидком бптуме позвол ет устойчиво регулировать свойства асфальтобетонной , обеспечивает требуемые реологические свойства комплексного в жущего, увеличивает сцепление органической части смеси с минеральным наполнителем, особенно со вновь вводимым. Описываема асфальтобетонна смесь может быть использована дл городских дорожных покрытий, полов промзданий и т. п. Предмет изобретени 1.Асфальтобетонна смесь, содержаща регенерированный асфальтобетон, наполнители и добавки, отличаюп а с тем. что, с целью повышени степени водост1м1кост1 и прочности асфальтобетона, в качестве добавки использован о-12%-ный раствор термопластичного полимера на основе производных акриловой или метакриловой кислот, имеющего в своей структуре амидные группы, в жидко битуме. 2.Смесь по п. 1, отличающа с тем. что указанные компоненты она содержит в J/o по весу: регенерированный асфальтобетон 78-91 нанолннтель7,8-21An asphalt concrete mix is known that contains regenerated asphalt concrete, nanofillers and additives, from which asphalt concrete is obtained with low resistance to water and strength. The purpose of the invention is to increase the degree of water resistance and strength of asphalt concrete. This is achieved by using a 5-12% solution of a thermoplastic polymer based on acrylic or methacrylic acid derivatives, which in its structure has amide soils, in liquid bitumen, as an additive. Asphalt concrete mixture may contain these components in J / o by weight: regenerated asphalt concrete 78-91 napolpitel7,8-21 polymer solution 0.3-2.2 Asphalt concrete recovered by heat and radioactivity is used as a regenerated asphalt concrete not exceeding 150 ° C. In this method, bitumen is not practically oxidized, which is important for maintaining the stabilized structure of bitumen-mineral material formed during the operation of the asphalt concrete pavement. As the active polymer can be used, for example, a copolymer of butlap with methacrylamide or polyacrylamide. The use of a solution of active polymer in liquid bptum allows one to steadily control the properties of asphalt concrete, provides the required rheological properties of the complex binding agent, and increases the adhesion of the organic part of the mixture with mineral filler, especially with the newly introduced one. The asphalt concrete mixture described can be used for urban pavements, flooring, etc. Object of the invention 1. Asphalt concrete mixture containing regenerated asphalt concrete, fillers and additives differing from that. that, in order to increase the degree of water flow and the strength of asphalt concrete, an o-12% solution of a thermoplastic polymer based on acrylic or methacrylic acid derivatives, having amide groups in its structure, in liquid bitumen was used as an additive. 2. A mixture according to claim. 1, characterized in that. that these components it contains in J / o by weight: regenerated asphalt concrete 78-91 nanorns7,7-21
