This study develops a set of criteria for cycling routes. This was accomplished by surveying the active bicycling community in rural East Texas. The survey was designed to determine demand, preferences and cyclist's experiences on existing routes. Demand was determined by days and miles per week cyclists currently ride and the type of bicycle(s) they own. Cyclist preferences were determined for…

Deflection testing and backcalculation have been conducted on all types of concrete highway and airfield pavements for many years. Backcalculation of the in situ slab elastic modulus and the effective k-value or elastic solid subgrade modulus (beneath the slab) from deflection basins was first proposed by Westergaard in 1925 and actually conducted in the 1930s. Over the past decade, backcalcula…

Subsurface drainage plays a critical role in maintaining the structural integrity and long-term performance of pavement systems. This study investigates the effects of subsurface drainage conditions on the performance of asphalt and concrete pavements, focusing on factors such as moisture infiltration, load-bearing capacity, and pavement deterioration mechanisms. Poor drainage systems can lead …
