Abstract

The paper presents research on the possibility of utilizing materials recycled from concrete pavements through crushing them in crushers and re-incorporating into pavement courses. From the economic and technical points of view crushed concrete waste can be an alternative source of aggregates, replacing natural aggregates. Crushed concrete was tested with regard to the current requirements which aggregates applied in layers made of unbound and cement bound mixtures must meet. Concrete rubble is shown to be suitable a material for re-incorporation into pavement road surface courses and limitations on the use of such materials are indicated.

从混凝土路面回收的骨料用于未粘结和水泥粘结混合料层的适用性

本文介绍了利用混凝土路面回收材料的可能性，通过破碎机将其粉碎并重新纳入路面。从经济和技术的角度来看，破碎的混凝土废料可以作为骨料的替代来源，取代天然骨料。对破碎混凝土进行了测试，以满足当前要求，即由非粘结和水泥粘结混合料制成的层中应用的骨料必须满足。混凝土碎石被证明是一种适合重新掺入路面路面的材料，并指出了使用这种材料的限制。
