Abstract (en)
[origin: WO9319251A1] A resilient annular transition collar (16) is provided for roadway structures (10), including manholes (12) and catch basins, which acts as a flexible transition between the rigid structure or frame of the manhole (12) and the semi-rigid structure of the asphalt paving (10). The resilient transition collar (16) absorbs any movement of the pavement during expansion and contraction and this absorption avoids the prior art problems of break-up, cracking and separation between manhole and pavement. Risers or adjusting rings may be employed in conjunction with the transition collar to ensure a flush fit between the pavement (18) surface and the upper surface of the transition collar (16). A mold structure (50) for forming the collars includes heat transfer studs (62) to provide an increased production rate.
