Abstract:

One of the major obstacles facing rapid bridge construction for typical span type bridges is the time required to construct bridge abutments and foundations. This can be remedied by using the controlled low strength materials (CLSM) bridge abutment. The CLSM bridge abutment comprises full-height precast concrete panels attached to a CLSM backfill via epoxy-coated steel anchors. The main objective of this study is to examine the application of the CLSM bridge system in typical span type bridges used in railroad and highway situations. To do so, an instrumented, large-scale laboratory test was performed on a CLSM bridge abutment to investigate its performance due to the application of a monotonically increasing sill (foundation) pressure. The test results show that the CLSM bridge abutment, with a relatively short cure time of 7 days, is capable of carrying bridge loads with a reasonably large safety margin, and with minimal deformations.
