Multi-cracks Modeling in Reflective Cracking [PDF]
, 2012 Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation. The stress concentration in the overlay

Accelerated Laboratory Testing for Reflective Cracking [PDF]
Romanian Journal of Transport Infrastructure, 2021 Abstract One of the most used methods of rehabilitation of road structures is the laying of a protective asphalt layer over a degraded concrete. The main problem of this solution is the reflective cracking, more precisely the transmission of the existing cracks in the lower layer in the asphalt pavement.
