Изобретение относитс к дорожному строительству, в частности к способам ремонта покрытий автомобильных дорог.The invention relates to road construction, in particular to methods for repairing road pavements.
Целью изобретени вл етс снижение материалоемкости, трудоемкости за счет продлени сезона ремонтных работ;The aim of the invention is to reduce material consumption, labor intensity by extending the repair season;
Способ ремонта покрыти автомобильных дорог, включает обработку поверхности трещины и ее заполнение.. Обработку поверхности трещины осуществл ют увлажнением, а заполнение производ т, безусадочным сухим цементом , причем после заполнени трещины на нее сверху нанос т слой битумной эмульсии.The method of repairing road coatings involves treating the surface of the crack and filling it. The surface treatment of the crack is carried out by moistening, and the filling is performed with a non-shrink dry cement, and after filling the crack, a layer of bitumen emulsion is applied on top of it.
Безусадочный цемент гидратируют в результате взаимодействи с влагой наход щейс в трещине, а также с влагой, образующейс при распаде битумной эмульсии. Битумна эмульси играет роль гидроизол ционного сло . Она предотвращает попадание излишней влаги с поверхности покрыти в заполненную цементом трещину и, кроме тоNon-shrinking cement is hydrated as a result of interaction with the moisture in the crack, as well as with the moisture generated during the disintegration of the bitumen emulsion. The bitumen emulsion plays the role of a waterproofing layer. It prevents excess moisture from entering the surface of the coating into the crack filled cement and, besides

го, преп тстЁует испарению влаги из цементного теста, что обеспечивает нормальные услови ее твердени .It prevents evaporation of moisture from the cement paste, which ensures normal conditions for its hardening.
Пример. Производ т принудительную разделку кромок трещины с помощью фрезы диаметром 8 мм с увлажнением . Заполн ют трещину безусадочным цементом. Обрабатывают поверхность трещины битумной эмульсией в количестве 0,2 кг/м с помощью окрасочного агрегатаExample. Produced forced cutting of the edges of the crack using a cutter with a diameter of 8 mm with moisture. Fill the crack with non-shrink cement. Treat the surface of the crack with a bitumen emulsion in the amount of 0.2 kg / m with the help of a painting unit
