Приведена характеристика техногенного сырья, имеющегося в Ростовской области: золошлаковых отходов и горелых пород шахтных отвалов. Экспериментально доказана возможность использования заполнителей из горелых шахтных пород при строительстве технологических и подъездных дорог, промышленных площадок. Показано положительное влияние материалов из горелых пород и золошлаковых отходов на физико-механические свойства бетонных композиций для изготовления тротуарных плит и элементов мощения дорог. Изложен характер упрочнения композиций, содержащих техногенное сырье в слоях дорожной одежды и бетонных смесях. Установлено, что замена минерального сырья техногенными отходами сопровождается улучшением физико-механических свойств бетонов при одновременной экономии цемента и традиционного минерального сырья – щебня и песка. Использование золошлаковых отходов и горелых шахтных пород позволяет сэкономить от 10 до 50 % цемента и 100 % природного щебня и песка.
