Polished Stone Value of Volcanic Rocks Used as Aggregates: A Case Study from the Bohemian Massif, Czech Republic

Popis výsledku v původním jazyce

Volcanic rocks represent about 34 % of the crushed stone marketed in the Czech Republic. These rocks are used for all kinds of construction purposes including roads. In a recent study, we focused on their performance in asphalt concrete designed for roadsurfacing. The samples were from 39 active quarries, representing all major volcanic rock types, and belonging to three different geological epochs-Neoproterozoic, Upper Palaeozoic, and Tertiary. The rocks under study encompassed numerous rock fabric subtypes including fine-to coarse-grained, porphyritic, hemicrystalline, etc. These rocks have been studied for their mineralogical composition and rock fabric quantitatively (including image analysis). The polished Stone Value (PSV) of each rock type hasbeen determined following the respective standard. According to Czech standards for road surfacing, PSV above 53 is required, PSV over 56 is required for high traffic and dangerous road sections. From the 39 rock types studied, only 17 (3
