heal.abstract	The cold in place recycling (CIPR) technique using foamed asphalt and cement as stabilizers was applied for the rehabilitation of a severely cracked originally asphalt pavement with cement treated base (CTB), which was considered as a test section. Three years after construction of the test section, a limited number of transverse cracks were observed on the asphalt pavement surface. In order to investigate the severity and the origin of the cracking, several cores were taken along the location of the cracks. In-situ non-destructive tests (NDTs) using the FWD were also performed 4 times within a two year period after the observation of the cracks. Intensive coring investigation has shown that the transverse cracks were all the way through the asphaltic overlay and the recycled layers as well. According to the deflection analysis no significant reduction of the. load transfer efficiency was observed during the measurements along the location of the transverse crack. Backcalculated moduli of the recycled material did not show reduction during the two years of pavement performance after the appearance of the crack. Strain response analysis has shown no increase of the critical strains in the body of the recycled material during this period of monitoring. © 2008 Taylor & Francis Group, London.	en
