The report describes the reconstruction and instrumentation of an 18.5 foot diameter structural-plate culvert under 85 feet of cover. The 'imperfect trench' type of construction was used. The instrumentation consisted of: SR-4 strain gages placed on the culvert walls at approximately mid-height; Carlson Soil Stress Meters; placed on the outside walls of the culvert and in the fill; and settlement cells which were taken on levels on the culvert invert, vertical and horizontal diameters, and levels of the roadway profile. Overall, the instrumentation performed satisfactorily. Results correlated well and demonstrated that the vertical load on the culvert was much less than the weight of the overlying column of earth - a highly favorable load condition which the 'imperfect trench' method of construction was expected to produce. There was no measurable differential settlement of the pavement attributed to the 'imperfect trench' method of construction. (BPR abstract)
