Dear David, Dear Khaled,
RILEM organises international conferences every four years on this topic, under
the name : 'Reflective Cracking in Pavements'. The last one was in Ottawa this
year (in April or May, I believe). This is THE reference. Actually, a very wide
range of study are presented in the RILEM's abstracts, including many laboratory
simulations, etc. About four of these conferences have been held since the mid
80's.
For ourselves, we also have gained some experience in this area, through
'unformal' follow up of existing roadways (up to ± 10 years). I am very
interested by this topic, which represents a real challenge in northern climate
compared to, for example, the south of the US (thermal and hydraulic conditions
are much more critical here).
Actually, there might be some opportunity to exchange some more informations in
a short future ! We also have in mind to develop a real scale project on this
topic, with buried instrumentation, etc, which would focus on municipal roadways
much more then highways.
Best regards,
--
