Abstract
For the creation of underground works such as road and railway tunnels, critical infrastructure facilities, collectors, multi-purpose halls, it is necessary to excavate rock material from the massif. This generates surplus and unnecessary rock material, which in most cases ends up as waste in a nearby stockpile or waste dump. Often this material can meet the quality requirements for construction aggregate. Therefore, this material can be reused as a source of aggregate, thereby reducing construction costs in a circular economy. The article briefly describes the methodology of the evaluation and testing of waste rock from tunnels for various purposes of its reuse as aggregate.
