I was wondering if the pavement thickness (determined using AASHTO Rigid pavement equation)has a direct relationship with the concrete modulus of elasticity.
The concrete modulus of elasticity is estimated to be around 57000(f'c)^0.5. Therefore, the higher the compressive strength, the greater...
Mississippi DOT requires density between 92% and 95% of maximum density (AASHTO T 209)(which I believe most state agencies specify) for dense graded courses. How do you correlate maximum density determined using AASHTO T 209 vs. Marshall (75 blows) compaction density. FAA specs require 96.3%...
Hi,ryanjs. I'm fairly new to the field, but I am certain that your computer science degree would make a great asset if you decide to venture into transportation or water resources field. Both of these fields require extensive computer knowledge because of their inherent dynamic nature, and the...
Hi, I have found a copy of AutoTurn, and am testing the templates. The research paper was an excellent guide to the geometric design. Thanks a lot!
The concrete paved V-ditch is an existing structure. I initially thought about replacing it with vegetative cover to provide more room for...
Hi, I have recently received a project to improve an existing gravel parking lot to a concrete paved parking lot. The school bus parking lot is approximately 4 acres, and require a capacity of roughly 200 bus lots. The typical bus dimension is 8'x35'.Does anyone know any standard or design...
