Further Studies Of Vapor-Liquid Equilibria Of Methanol-Ethylene Glycol-Water, Herbert Benjamin Sachs
Further Studies Of Vapor-Liquid Equilibria Of Methanol-Ethylene Glycol-Water, Herbert Benjamin Sachs
Masters Theses
"The freezing points of the ternary system methanol-glycol-water have been investigated by Conrad, Hill and Ballman. The vapor-liquid equilibria of the same system was studied by Sjoberg. These investigations were carried out to determine the properties of the system relative to its possible use as an antifreeze mixture.
Since Sjoberg's work in 1948, the improved Othmer equilibrium still has been introduced for vapor-liquid experimental determinations. It is therefore the purpose of the present investigation to evaluate the use of this still, compare results with those obtained by Sjoberg, and analyze ternary mixtures for the entire range of glycol concentrations.

Observations On The Constitution And Characterization Of Paving Asphalts, James H. Havens, W. F. Daniels
Kentucky Transportation Center Research Report
This paper contains results of analyses with asphalts of various composition and derivation. The objective of the study is to define and correlate constitution and fundamental character of asphalts in a manner significant to their use in highway pavements.
Further confirmation of the existence of three discrete solubility fractions in asphalts was obtained by extraction methods and by paper partition chromatography. Paraffin bodies were revealed by microscopic examination of thin films. Asphaltene fractions showed the presence of particulate material by electron microscopy and also revealed indications of peptized asphaltene bodies. Oils dialyzed from asphalt exhibited u.v. fluorescence similar to components …

An Investigation Of The Binding Properties Of Limestone Dust, William E. Howard, Ellis G. Williams
An Investigation Of The Binding Properties Of Limestone Dust, William E. Howard, Ellis G. Williams
Kentucky Transportation Center Research Report
A proper quantity of dust particles of various sizes has long been recognized as important in the construction of stone bases and pavements. Screenings for water bound macadam bases are required to contain not less than a specified amount of dust sizes, and dense-graded limestone bases have controlling limits for the dust fraction. It is generally assumed that these particles serve a dual purpose: (1) in filling void spaces created by larger particles, thus enhancing the gross structure of the aggregate, and (2) in acting as a binder material in the presence of water. Furthermore, it has been demonstrated that …

Studies Of The Suitability Of Expanded Shale Aggregate For Use In Cement Concrete, Claude M. Brown Jr., Loren H. Strunk, Dave H. Sawyer
Studies Of The Suitability Of Expanded Shale Aggregate For Use In Cement Concrete, Claude M. Brown Jr., Loren H. Strunk, Dave H. Sawyer
Kentucky Transportation Center Research Report
Expanded shale is one of several artificial lightweight aggregates currently used in the production of lightweight concrete. Its use has become rather widespread through recent improvements in production techniques, mix designs, placement methods, and air entrainment. However, various types of lightweight concrete as such is not of recent origin, having been used in this country for more than a half century.
Expanded shale aggregates are produced by heating a suitable shale to the point of fusion. Gases within the shale expand and thus form thousands of tiny air cells within the mass which are retained upon cooling and solidification. The …

Blown Mulch For Roadside Erosion Control, Jason C. Taylor
Blown Mulch For Roadside Erosion Control, Jason C. Taylor
Kentucky Transportation Center Research Report
In May 1954, the Division of Construction brought to the attention of the Research Division the fact that an effort was being made (for the first time in Kentucky) to revise the conventional manner of applying straw mulch to a seeded right-of-way. This innovation was to be achieved with the use of a recently-invented machine known as the "Finn Mulch Spreader", which is capable of mixing a straw mulch with some adhesive substance and then blowing the mixture onto the seeded area. The intent was to achieve a reasonably homogeneous mat-like structure composed of pieces of straw attached to each …
