Results of a European round-robin aiming to identify and quantify scattering sources impacting the polished stone value (PSV) of aggregates, and to assess the reference PSV of Herrnholzer granite, are presented and discussed. This reference value corrected against quartz dolerite control stone is calculated as PSV ref HE = ± Cited by: 2.   Skid resistance is one of many important aggregate properties, the polished stone value test is performed on aggregate particles that pass a . This research aims to evaluate relationship of aggregate friction capacity through the polished stone value and asphalt concrete skid resistance. In this study, a series of polished stone value tests on the study aggregate of limestone and sandy mudstone and British pendulum tests for skid resistance value of polished hot mix asphalt (HMA) : Preda Pichayapan, Phittayoot Chaleonpan, Peerapong Jitsangiam, Pongsakorn Wongchana. 41 Polished Stone Value (PSV) [4,7]. Physically, PSV is a corrected residual friction coefficient calculated from the 42 measurement of kinetic energy loss when the rubber slider is .

  A set of 39 different volcanic rocks was studied for performance as crushed stone for road surfacing (wearing course) aggregates using two technological tests: the polished stone value (PSV) test, aimed at evaluating resistance to polishing (skid resistance), and the Nordic abrasion value (A N) test, as a proxy to wear by studded tires (resistance to abrasion).Cited by: 4. polished stone value See AGGREGATE TESTS. Source for information on polished stone value: A Dictionary of Earth Sciences dictionary. The value of PSV increases rapidly and then increases slowly as the value of C/M increases. L.A. abrasion loss and the crushing value are also key indicators for evaluating the aggregates used in the pavement surface coatings. The results of L.A. abrasion testing and the crushing value tests are shown in Figure 15 and Figure Author: Fa Yang, Bowen Guan, Jingyi Liu, Jiayu Wu, Jianan Liu, Chao Xie, Rui Xiong. The degree of polish imparted depends on the traffic conditions (e.g., volume, weight, speed, acceleration, breaking), road geometry (e.g., alignment grading) and the.

related. The list of acronyms and abbreviations related to PSV - Polished Stone Value. Several test methods exist to determine the aggregate properties of rock materials: the polished stone value test (Đokić et al. ), the slake durability test (Miščević and Vlastelica ), the Nordic test (Krutilová and Přikryl ), aggregate crashing and aggregate impact value tests (Palassi and Danesh ), and Washington. Factors affecting the performance of cast iron pipelines: A review of US observation and research investigations: Some Aspects of the Interaction between Landslides and Forestry Operations: A model set of asphalt sustainability indicators: Factors affecting the Polished Stone Value tests. The BPN value associated with accelerated polishing is defined as the polished stone value (PSV), which is a quantitative representation of the aggregateâ s terminal frictional characteristics. Higher values of PSV indicate greater resistance to polish.
