Feldspar Greywacke High Polished Stone Value Aggregate

feldspar greywacke high polished stone value aggregate

more dense rock may give a good polished stone value because the rock is homogeneous as well as having a good impact value. High clay content gives poor Aggregate Impact Value (AIV) and poor abrasion but good polished stone values. A shale will have poor strength but better PSV. The relative quantities of quartz, feldspar and. Get Price

Aggregate Test - Northstone Materials

Polished stone value (PSV) - This is a most important test that an aggregate can undergo if it is to be used as a road surface course. If an aggregate polishes too much under the polishing effect of vehicle tyres, the road surface becomes very slippery, especially when wet, and the number of skidding accidents can increase. For the test, 10 mm chippings are placed face-down in a …
