The reflective cracking in thin surfacings
, 1998 This paper shows a laboratory study on reflection cracking in thin surfacings, where the reflective cracking take an important point in pavement life, undertaken with the Reflective Cracking Device and the Crack Activity Meter. The Crack Activity Meter was used to measure load associated differential vertical and horizontal movement between the two ...
