1 Scope
This document specifies a method of comparing traffic noise on different road surfaces
for various compositions of road traffic for the purpose of evaluating different road
surface types. Sound levels representing either light or heavy vehicles at selected
speeds are assigned to a certain road surface. The method is applicable to traffic
travelling at constant speed, i.e. free-flowing conditions at posted speeds of 50 km/h
and upwards. For conditions where traffic is not free flowing, such as at junctions
and where the traffic is congested, the method is not applicable.
A standard method for comparing the noise characteristics of road surfaces gives road
and environment authorities a tool for establishing common practices or limits regarding
the use of road surfaces meeting certain noise criteria. However, it is not within
the scope of ISO 11819 (all parts) to suggest such criteria.
The statistical pass-by (SPB) method is suitable for use for the following main purposes:
— to classify road surfaces according to their influence on traffic noise (surface classification);
— to assist in verifying conformity of production of road surfaces;
— to evaluate acoustic performance of road surfaces throughout operation relative to
new condition;
— to evaluate the influence of different road surfaces on traffic ...
