Publisher's Synopsis
The use of cement bound material roadbases in flexible composite pavements in the United Kingdom is limited by the reflective cracking that occurs due to thermal shrinkage. Induced cracking is intended to diminish the effect of reflective cracking, thus enabling the thickness of the flexible layers to be reduced and consequently increase the competitiveness of flexible composite pavement due to initial construction cost savings and increased pavement life. This report presents an update on current worldwide research on the subject, together with a description of the construction of full-scale trials and initial monitoring that took place to evaluate the effectiveness of induced cracking in the UK. A discussion of the promising results is provided together with recommendations, including a draft specification, for further use of induced cracking in the UK.
