Comparing Measured and Theoritical Depth Deflections Under a Falling Weight D…
Trr No. 1260 Pavement Design, Management And Performance., pp. 216-265 The following conclusions can be drawn : 1. Setting a depth to bedrock of 20 ft produced a better fit between measured and calculated depth deflections. 2. The average errors on the thicker sections (9 and 12) were acceptable (less than 9 percent per sensor), indicating that linear elasticity for backcalculating E values is…
Methodology for Processing, Analyzing, and Storing Truck Weigh-in-Motion Data
Trr No. 1311 Pavement Design, Management And Performance, pp. 51-59 The use of high-speed weigh-in-motion (WIM) systems does eliminate the problems of high cost and slow static weight stations. However, another problem is usually generated--because it is easy to weigh all truck traffic with a WIM system, this type of system generates large amounts of data that require tremendous time and effor…

Trr No. 1377 Pavement Design, Management, And Performance, pp. 36-44 Nondestructive deflection testing using falling weight deflectometers (FWDs) is one element of the monitoring effort currently under way by the Strategic Highway Research Program (SHRP) for the Long-Term Pavement Performance (LTPP) study. Because accurate data are key to the success of the LTPP study, SHRP has implemented a n…
Influence of Statistical Variation in Falling Weight Delfectometers on Paveme…
Trr No. 1377 Pavement Design, Management, And Performance, pp. 57-66 A relatively simple approach that is based on a Monte Carlo simulation procedure is presented to statistically investigate the influence of variation in falling weight deflectometer (FWD) measurements on pavement analysis. The factors considered are pavement moduli and pavement performance or response strains that correlate w…
