Warden Station
 The
Toronto Transit Commission’s (TTC) Warden Station is an intermodal
transfer point on the Bloor-Danforth Subway Line. Heavy loads from
TTC buses, combined with a site layout requiring severe bus turning
movements, caused a failure of the asphalt pavement topping, commonly
known as rutting. The asphalt was so rutted at turn locations that
the original concrete pavement showed through at several locations.
In 1998, TTC decided that the time had come for a complete reconstruction
of pavement in all bus areas. The original concrete pavement had
been constructed when the Bloor-Danforth Subway was extended to
Islington and Warden in 1968, and was topped with asphalt about
15 years ago. The new pavement is 12-inch (250-mm) thick concrete
that is specifically designed for the heavy axle loads that transit
buses carry. Additional features to make the construction long-lasting
included short spacings between pavement joints and use of steel
dowels across joints and deformed tie-bars at curbs.
