Design of Continuously Reinforced Concrete Pavement with Heat Transfer System for a Bus Terminal in Hamilton


MacNab Street Bus Terminal is located between Main Street and King Street in downtown Hamilton and is primarily used as a transit terminal. An existing underground concrete tunnel structure is located beneath portions of the road. The proposed pavement improvements include the reconstruction and widening of MacNab Street with a concrete pavement structure and the construction of two new concrete passenger platforms complete with canopies. Consideration was initially given to the reconstruction of MacNab Street using a jointed plain concrete pavement (JPCP). However, as a heat tracing system was designed for placement within the pavement, it was decided that the new structure should be a continuously reinforced concrete pavement (CRCP). This reduced the number of transverse contraction joints in the pavement from 40 to just 2. The concrete pavement was designed on a 50 mm thick insulation. The new pavement will be subjected to about 500 buses per day with the possibility of increasing to as many as 750 busses per day. The design traffic loading for a 20 year period is 26 million ESAL’s. There is very limited experience in Canada with the design of CRCP. There are a few CRCP pavements in Quebec and one in Alberta. The initial pavement design was carried out in accordance with the 1993 AASHTO Guide for the Design of Pavement Structures. The reinforcement in the CRCP on MacNab terminal was designed following the procedure developed by the Quebec Ministry of Transportation (MTQ). In order to accommodate longitudinal movements at the CRCP ends and to provide transition from CRCP to asphalt pavement, two terminal expansion joints were designed at both ends of the pavement. The influence of the heating pipes and allowable movement across transverse contraction joints was also considered in the design.
