To reduce the incidence of reflection cracking in asphalt surfacing layers of flexible composite pavements the Transport Research Laboratory has investigated flexible composite roads that have used induced cracking techniques in the construction of cement bound roadbases in the UK. Full-scale trials were constructed in 1996 to assess various techniques of inducing cracks in cementitious roadbases, different thicknesses of asphalt layers and different cementitious materials. The performance of these trials is being used to validate a new design method. Current research is discussed using finite element techniques as an analytical tool to understand the behaviour of composite pavements incorporating induced cracks to minimise reflection cracking as is the development of a new design method. In addition, the validation of the analytical model using the performance of both historical and current full-scale trials in the UK is discussed.
