Abstract
Cracking is the main distress mechanism that takes place in the failure of road pavements. This has led
to a new approach in the pavement cracking study based on the cracking propagation mechanisms from
the pavement tensional state and bituminous mixtures resistance to cracking propagation. This project
is aimed to analysing the cracking resistance of mixtures at different temperatures to determine the
effect of load and temperature. In order to achieve these objectives two new tests developed at the
Road Research Laboratory of the Technical University of Catalonia will be applied: one to evaluate the
cracking resistance of bituminous mixtures under slow and monotonic loads, FENIX test; and the other,
under rapid and cyclic loads, EBADE test. The cracking propagation process of the mixture as a
function of the tensional state and fracture energy obtained from the tests will also be analysed. The aim
of this project is thus to model the cracking propagation in order to develop new design methods that
allow to design pavement structures with improved service performance and durability.
