Polished Stone Value Test Procedures and Equipment

Aggregate Abrasion Value Polishing Stone. Introduction In 1950 increased traffic flows and higher speeds on trunk roads, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance.

Aggregate Impact an overview ScienceDirect Topics

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value ACV and aggregate impact value AIV obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.

Los Angelese Methods For Aggregate Crushing

Some familiar aggregate tests previously used in the UK and Ireland, such as Aggregate Crushing Value, Ten Percent Fines Value, Aggregate ImpactLos Angeles Test LA The complete test is detailed in BS EN 1097-2, under the title Methods for the determination of resistance to fragmentation .

changed. The remaining tests, such as Polished Stone Value, Aggregate Abrasion Value, and Magnesium Sulphate Soundness, have been retained virtually intact. Aggregate strength is now assessed using the Los Angeles test, which has replaced the Ten Percent Fines Value. Other European tests, such as Methylene Blue level of harmful fines, Shape Index particle length to width ratio, Impact Value NOT former BS

Polished Stone Value Test Procedures and Equipment

The percentage mass of fines passing a 2.80mm BS test sieve formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values.
