Influence of engineering properties on Polished Stone
2015年12月30日 The effect of WA s on PSV is strong whereas the relationship between WA a and the PSV explains approximately 25% of the variance of the PSV (Fig. 4 b, models 3 and 6 in Table 2). Statistically significant negative linear correlations were found between aggregate density and PSV (Fig. 4 c, models 4–5, Table 2).

Higher PSV and other aggregate properties - Semantic
2005年5月1日 PSV is a standard laboratory measurement of skid resistance. Many years of testing has shown that certain types of aggregate give higher values in relation to others. There is a general ranking of rock types e.g. gritstone has better PSV than basalt which is better than limestone. In the UK this natural ranking has resulted in the majority of higher
