COST 347 Objectives
Enable future cost-sharing co-operative research
ventures between public and private sector
research institutions and companies Improve the
possibilities for non-owner institutions to make
use of existing ALT facilities Provide the
background for beneficial co-operation with
related research activities outside Europe in the
future
To develop a European code of good practice to
optimise the use of Accelerated Loading Testing
facilities and improve the application of results
from these facilities

COST 347 Definitions

• The pavement section should have more than one
  layer
• Traffic loading can be simulated by means of
  rolling wheels, hydraulic actuators
