15-12-2015· Notice that correcting the polishing level of test specimens using a control stone and its reference value as suggested by Tubey et al. is similar to narrowing the setting tolerance on the wheel force, since no correlation is visible on Fig. 2a between wheel force and corrected values PSV40 or PSVHEm. 5.2.2. Particular case of PSV40 scattering
The goal of this work was first to establish the relationships between the PSV values and the microstructural and mineralogical features of the aggregates and surface micro-roughness, and then to establish the behavioural differences between natural and artificial aggregates. The results obtained indicate that the surface micro-roughness and the different PSV values of the natural aggregates ...

The Accelerated Polished Stone Value Tester is applicable for simulating the polishing role of auto tire to the road pavement. It determines the aggregate polishing value by accelerated polishiing to the aggregate used on the pavement.
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 …
This Part of BS 812 describes the method for determining the polished stone value (PSV) of an aggregate. The PSV gives a measure of the resistance of roadstone to the polishing action of vehicle tyres under conditions similar to those occurring on the surface of a road. The test is in two parts.
Determination of the polished stone value. BS EN 1097-8 describes the test method for mechanical and physical properties of aggregates. This part of the BS EN 1097 series of standards concentrates on determining the polished stone value (PSV) of a coarse aggregate used in road surfacing.
polished stone value (PSV) and the petrology of a range of natural aggregates drawn form commercially operating quarries in the UK. Initially, the polished stone value of each aggregate was measured in a programme of standard tests, in order to make a basis for the comparison of any alternative test procedure to be adopted.
The Polished Stone Value of aggregate is measured using a standardised test (BS EN 13043: Aggregates for bituminous mixtures and surface treatments). This gives a measure of the resistance of the aggregate to the polishing action of vehicle tyres under conditions similar to those occurring on a road surface.The PSV of an aggregate is a measure of the resistance of an aggregate to polishing.
Results are expressed as 'polished stone values' (PSVs), the mean of the four test specimens of each aggregate. International Use of the PSV Test - BS 812 This British Standard has been adopted and used widely throughout the world. It is the only test with available equipment to calculate PSVs.

The deriving of the polished stone value PSV does not give a good indication of on road performance The friction come degree of aggregate polishing is derived by carrying out a British pendulum test which produces the PSV number At this ...
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 . Read More

Sep 24, 2012 The Polished Stone Value of aggregate is measured using a standardised test (BS EN 13043: Aggregates for bituminous mixtures and surface treatments) This gives a measure of the resistance of the aggregate to the polishing action of vehicle tyres under conditions similar to those occurring on a road surfaceThe PSV of an ...
INTRODUCTION The Polished Stone Value of aggregate is measured using a standardised test (BS EN 13043: Aggregates for bituminous mixtures and surface treatments). This gives a measure of the resistance of the aggregate to the polishing action of vehicle tyres under conditions similar to those occurring on a road surface.The PSV of an aggregate is a measure of the resistance of an aggregate …
The primary factors that affect the validity of the Polished Stone Value (PSV) test for predicting the ability of stone chips to provide a safe braking surface for road users is evaluated.
29-07-2015· Skid resistance is one of many important aggregate properties, the polished stone value test is performed on aggregate particles that pass a 10 mm sieve and ...

The Polished Stone Value of aggregate gives a measure of resistance to the polishing action of vehicle tyres under conditions similar to those occurring on the surface of a road. The action of road vehicle tyres on road surfaces results in polishing of the top, exposed aggregate surface, and its state of polish is one of the main factors.
An accelerated polishing machine was used to create reduction of skid resistance of HMA slabs. Test results showed that reduction of polished stone value (PSV) of limestone 47.6% leads to a decrease of skid resistance value (SRV) approximately 43.8% of HMA slabs.
