DATE COMPLETED: SEPTEMBER 1991
The Fort Bend Flood Control Water Supply Corporation was planning drainage improvements to Middle Oyster Creek, located in Quail Valley subdivision in Missouri City, TX.
The improvements included widening of the creek channel to improve flow and lessen flooding potential. Excavated material from the creek would be hauled out of the subdivision over two streets; Hampton Drive and Glenn Lakes Lane. Due to concern that the proposed hauling may damage the residential streets, it was necessary to evaluate the amount of damage that would be caused to the streets by using them as haul routes. The project included field investigations consisting of visual condition surveys, roughness measurements, nondestructive deflection testing and pavement coring. The prehaul condition of both streets was assessed based on the field data and laboratory tests on pavement materials. Stress was computed in the pavement from the projected haul truck traffic and compared to the in-place strength. The projected amount of reduction in pavement life and the projected amount of repairs were determined.
