The article presents the results of investigations carried out to compare and provide information on the working and ultimate load behaviour of resin grouted anchorage systems in concrete. Design procedures are proposed for estimating the ultimate capacity of single bolts and these are compared with a large number of tests, and with alternative recommendations. The bolts tested were either straight deformed reinforcing bars or block-ended bars and were resin grouted in holes drilled in hardened concrete. (TRRL) transit ridership. The economic comparison of alternative plans includes total as well as "relative" inflation of principal cost components. A key feature of the proposed methodology is including in the comparisons the costs of private automobile mileage that could have been replaced by transit. These costs are expressed as "fuel" and "all other" automobile costs; favorable transit system implementation schedules can then be identified as A function of parametrically assumed values for these two unit costs. A hypothetical example demonstrates the proposed method.(a)
