Abstract
1. Способ ремонта асфальтобетонных покрытий в зимних условиях и композиционная смесь материалов для его осуществления, заключающийся в производстве ямочного ремонта дорожных покрытий при температуре воздуха до -10°С горячей асфальтобетонной дорожной смесью на основе вязких или жидких дорожных битумов, укладываемой в предварительно разогретое дефектное место, отличающийся тем, что ремонт покрытий при температуре воздуха до -10°С производят в следующей последовательности: дефектное место покрытия обрабатывают 30%-ным водным раствором хлористого кальция из расчета 0,5 л раствора на один квадратный метр обрабатываемой поверхности; в обработанное место заливают заданное количество жидкого натриевого стекла; в залитое в ямку жидкое стекло засыпают заданное количество предварительно подготовленной сухой смеси песка и цемента, а в результате их смешения происходит мгновенное схватывание и твердение смеси материалов; поверхность отремонтированного участка покрытия обрабатывают 30%-ным водным раствором хлористого кальция, затем эту поверхность обмазывают разжиженным битумом и присыпают песком. ! 2. Композиционная смесь материалов по п.1, отличающаяся тем, что содержит следующие материалы, мас.%: ! жидкое натриевое стекло с плотностью, по меньшей мере, 1,3 г/см3, содержащее дополнительно, по меньшей мере, 8% карбамида17предварительно подготовленная сухая смесь песка и цемента, которая содержит 85% песка и 15%, по меньшей мере, портландцемента831. A method of repairing asphalt concrete pavements in winter conditions and a composite mixture of materials for its implementation, which consists in the patching of pavements at an air temperature of -10 ° C with hot asphalt concrete mix based on viscous or liquid road bitumen, placed in a preheated defective place , characterized in that the repair of coatings at air temperatures up to -10 ° C is carried out in the following sequence: the defective coating site is treated with a 30% aqueous solution of chlorine calcium soda at the rate of 0.5 l of solution per one square meter of the treated surface; a predetermined amount of liquid sodium glass is poured into the treated area; a predetermined amount of a previously prepared dry mixture of sand and cement is poured into the liquid glass poured into the hole, and as a result of their mixing, an instant setting and hardening of the mixture of materials occurs; the surface of the repaired coating area is treated with a 30% aqueous solution of calcium chloride, then this surface is coated with liquefied bitumen and sprinkled with sand. ! 2. The composite mixture of materials according to claim 1, characterized in that it contains the following materials, wt.%:! liquid sodium glass with a density of at least 1.3 g / cm3, containing additionally at least 8% urea17 a pre-prepared dry mixture of sand and cement, which contains 85% sand and 15% at least Portland cement83
