Resilient Modulus And Strength Index Properties Of Stabilized Base For Tennessee Highways, Wesley M. Macdonald
Resilient Modulus And Strength Index Properties Of Stabilized Base For Tennessee Highways, Wesley M. Macdonald
Masters Theses
Typical material used by the Tennessee Department of Transportation for highway bases was evaluated for application to the new Mechanistic-Empirical Pavement Design Guide. Two types of granular Tennessee highway base material were mixed with different stabilizers and tested in the lab according to AASHTO T-307 99 (2003). Unconfined Compressive Strength and California Bearing Ratio tests were also done in an effort to correlate these results with resilient modulus. Three different combinations of base and stabilizer were tested and modeling coefficients were produced. Base structural layer coefficients were generated and compared to coefficients currently in use by TDOT.

LSU Master's Theses
For pavement design practices, several factors must be considered to ensure good performance of the pavement over the anticipated life cycle. Such factors include, but are not limited to, the type of paving materials, traffic loading characteristics, prevailing environmental conditions, and others. Traditional pavement design practices have followed the standards set by the American Society of State Highway and Transportation Officials (AASHTO) which require the use of an equivalent single axle load (ESAL - 18 kip single axle load) for design traffic input. Recently, a new mechanistic-empirical pavement design guide (MEPDG) was developed to improve pavement design practices. The guide …
