heal.abstract	In recent years there has been a worldwide trend to link the success of pavement rehabilitation directly with the ride quality, or perceived ride comfort, of the resultant pavement. Both the rehabilitation technique employed and the materials used have the potential to influence the final ride quality achieved. Due to the limited availability of good quality materials and the increasing cost of hot mixed asphalt mixtures, cold in-place recycling (CIPR) is proving to be an attractive alternative for rehabilitating bitumen pavements. This paper deals with the use of CIPR with foamed bitumen for rehabilitating pavements (a treatment that over recent years has experienced a sharp increase in its use) and the effect it has on the ride quality of the rehabilitated pavement. Most CIPR-related research studies have tended to focus on material characterisation and mix designs performed in the laboratory, and/or an analysis of structural aspects of the pavement. The use of CIPR with foamed bitumen stabilisation has also been limited mostly to roads with low or medium traffic volume. Because of the lack of information available relating to the ride quality of pavements rehabilitated using this technique, the Greek Ministry for Public Works undertook a field study of a severely damaged section of a heavily trafficked highway pavement, part of the Trans European Network, which was rehabilitated using CIPR with foamed bitumen. To assess the effect on the ride quality of the pavement, roughness data were collected on an 'as built' basis prior to, during, and after the CIPR rehabilitation process. The pavement roughness was evaluated by measuring the international roughness index (IRI) values and, in addition, by calculating a series of power spectral density (PSD) functions in order to reveal the dominant wavelengths contained within the pavement surface. The results were used to assess the effectiveness of the CIPR with foamed bitumen treatment technique on the ride quality of the pavement. PSD analysis provides profound information concerning the amplitudes of surface wavelengths. Such information concerns the increase of the medium and long wavelength roughness of the CIPR layer surface, which seems to be crucial for ride quality.	en
