Another larger structure which is somewhat unusual is a 54-foot oolitic limestone arch bridge, carrying a stabilized gravel road 22 feet wide with a five-foot sidewalk on one side. This bridge spans McCormick's Creek a few hundred feet above the falls and carries the picnic ground road from the hotel to the Beech Grove area. This structure was built by the CCC camp which was located there for a...

Unbound granular pavement layers show a characteristic increase in moduli from the subgrade to the surface. The ratio of moduli between successive layers provides a direct and effective measure of pavement quality that makes due allowance for site conditions and seasonal effects beyond a contractor’s control. The modular ratio is therefore an effective indicator for performance-based specificat...

The saponification of an aromatic ester with an aqueous sodium hydroxide was studied within a heterogeneous reaction medium in order to determine the overall kinetics of the selected system. The extended thermo-kinetic model was developed compared to the previously used simple one. The reaction rate within a heterogeneous liquid-liquid system incorporates a chemical kinetics term as well as mas...
