Abstract:

Based on a recent study on cost efficient alternative bridge approach slab (BAS) designs (Thiagarajan et

al. 2010) has recommended three new BAS designs for possible implementation by MoDOT namely a) 20 feet cast-inplace

slab with sleeper slab (CIP20SLP) - for new construction on major roads, b) 25 and 20 feet precast-prestressed

slab with sleeper slab (PCPS20SLP)- for replacement and new construction applications on major and minor roads, and

c) 25 feet modified BAS without a sleeper slab for new CIP construction on minor roads (CIP25NOSLP). The objective

of the project here is to evaluate and compare the field performance of recommended BAS designs, their

constructability, and their impact on cost and schedule to the current MoDOT BAS design. Two PCPS20SLP, one

CIP20SLP and two CIP25NOSLP implementations have been implemented and studied for this report. One PCPS20SLP

panel was also tested in the laboratory for several washout conditions and for its ultimate capacity. Based on field

observations, data recorded and analyzed, preconstruction and post construction cost analyses this study has found that

all the suggested designs are performing well and are lower in cost compared to current designs used in practice.
