    A recommended procedure for load testing of concrete slab bridges in New Brunswick
    (University of New Brunswick, 2021) Gillett, Dustin; Arjomandi, Kaveh
    In New Brunswick, concrete slab bridges often rate poorly in shear during an analytical load rating. However, these bridges typically do not show signs of distress in service. This report explores the use of load testing to refine the load rating capacity of these types of bridges. Drawing from the current state-of-the-art on load testing, a standardized procedure for performing diagnostic load tests on concrete slab bridges in New Brunswick was developed. In addition, a hypothetical diagnostic load test was carried out using finite element simulation of the St. Leonard C.N.R. Overhead (North) bridge in St. Leonard New Brunswick. The hypothetical analysis resulted in a 7% increase at the abutment and 87% increase at the pier in shear live load capacity compared to traditional analysis methods.
