Paper presented at the ISRM International Symposium – EUROCK 2021, September 21–24, 2021
Paper Number: ISRM-EUROCK-2021-058
... Abstract This paper describes an approach applied in the design and construction of one cut at section km 23+200 - km 23+400 from the expressway A4, section Stip – Radovish, part of the Macedonian road network in construction. The cut is constructed in volcanogenic rock mass of andesitic type...

... into account. No attempt was made to read values of the limiting major principal stress (FO'J)from stress- strain curves or from ultimate strength - confining pressure plots. Five data sets have been collected for andesites from the Japanese Islands and from Ontario (Canada), five for basalts from...

... as aggregate for concrete or asphalt pavement. This aggregate rock is mostly sandstone, andesite and basalt. Aggregate rock is required to retain soundness for years. For example, aggregate for concrete structures in Japan is required to have a specific gravity of 2.5 or more, a water absorption rate of 3...
