    Abstract

    ![CDATA[Continuous reinforced concrete pavement (CRCP) is being used for heavily trafficked major infrastructure roads where a long service life is paramount. CRCP generally allows for the construction of long pavements lengths without transverse joints. CRCP is being used for the Westlink M7 (WM7) which is a 40km long privately financed toll road linking the M5 and M7 Motorways in Sydney, Australia. Each two-lane carriageway has a 10.5m wide continuously reinforced concrete pavement (CRCP) with an asphaltic concrete (AC) wearing surface. These carriageways cross 144 bridges along the length of the project. Current Australian practice requires that where the road encounters a bridge, the pavement be terminated at pavement end anchors and a bridge approach slab constructed to link the terminated CRCP to the bridge abutment. Transverse joints are required at both ends of the approach slab to allow for movements resulting from environmental and traffic loadings. This approach slab transition is not always smooth as the provision of the transverse joints can lead to discontinuities in the carriageway profile, particularly if the approach embankment settles.]]
