Comparative Study Of The Physical Properties Of Traffic Paints, A. C. Peed Jr.

Kentucky Transportation Center Research Report

Traffic or zone paints have become a major item of expenditure for highway departments with their increasing mileages and with the increase in traffic using the highways. Extending the mileage requiring marking and increasing the traffic wear on the marking has necessitated successively larger purchases of paint and associated equipment. As this market became larger increasing numbers of manufacturers have entered the field with a great diversity of formulations having differing properties.

In order to bring some order out of this situation the Research Laboratory in cooperation with the Division of Traffic undertook a study of the paints as offered …

Observation On Seal Coats, Tack Coats, Penetration Macadam, And Blade Spread Hot Mix In 1951, William B. Drake, Harvey J. Field Jr., S. T. Collier

Kentucky Transportation Center Research Report

During the 1950 construction season the Research Division observed the construction of several types of seal coats, a few tack coats and a penetration macadam pavement, A report, covering mostly construction practices on these projects, was submitted to the Research Committee at the February meeting in 1951. The report is titled "Observations on Seal Coats, Tack Coats, and Penetration Macadam Construction in 1950," and dated January, 1951.

A follow-up of most of these projects is submitted here, The performance of the seals was greatly influenced by failure of the bases during the very severe winter of 1950-51. Considerable frost action …

Spherical Lens Optics Applied To Retro-Directive Reflection, James H. Havens, Allie C. Peed Jr.

Kentucky Transportation Center Research Report

This paper describes some expedient applications of elementary optical principles to the evaluation of glass-bead reflectorizing systems for highway signs and markers. 'The optical function of spherical lenses in achieving reflex-reflection is illustrated both photographically and diagrammatically. Various optical designs are discussed and analyzed. By simple geometric optics, the efficiency of these systems is correlated with the practical performance criteria for retro-directive reflectorization.

Clay Mineralogy And Soil Stabilization, James H. Havens, William A. Goodwin

Kentucky Transportation Center Research Report

This paper attempts to resolve a general concept of soil rheology from the standpoint of clay mineralogy, ion-exchange, properties of clay-water systems, and volume relationships existing between clay-water systems and granular structures. Both theory and experimental data are presented.

In the experimental phase, synthetic soils of varying clay contents were prepared from carefully fractionated soil constituents. These were subjected to combined-stress analyses, tests for plasticity characteristics, and detenninations of other physical properties.

Vibratory Compaction Of Base Courses, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Early this month, on a field trip with Mike Logan of tho Bureau of Public Roads and R. D. Medley, Asst. Director of Design, I had an opportunity to look over a project in Ohio where a vibratory method of compaction was being used in tho construction of a macadam base course, This type of compaction is relatively new, it having been tried for the first time in this country about four years ago, To my knowledge, the first published report on the procedure was made in the Proceedings of the Highway Research Board, Volume 27, page 148, 1947.

Evaluation Of Plant Mix Surface Treatments, William B. Drake

Kentucky Transportation Center Research Report

This project made use of six bituminous materials and ten aggregate gradations in plant mix paving operations. The test sections were installed by state forces in 1942 and 1943. The object was to determine which aggregate gradation with a specific bituminous material was best suited for an application of 75 pounds per square yard surface treatment.

The bituminous materials used were MC-5, RC-5, RT-12, PAC-5 (85 to 100 penetration), PAC-7 (120 to 150 penetration), and PAC-8 (150 to 200 penetration). Twenty sections of MC-5 and ten sections of RC-5 were laid in 1942; all the sections containing the other materials …

Progress Report On Experimental Jointing Installations For Concrete Pavements, S. T. Collier

Kentucky Transportation Center Research Report

Combined in this report are descriptions of the progress of three individual experimental joint installations. Each of these includes a series of two or more experimental joints of special design, installed in concrete pavement in lieu of the conventional types employed in their respective construction projects.

These experimental joints included at one location a prefabricated neoprene seal; and, at two locations, aluminum load transfer devices, All installations were contraction joints only, Periodic inspections of these have been made and will be continued on two of the projects until adequate performance records are established. The condition of concrete about the joints …

Report No. 3 On A Concrete Pavement Without Transverse Joints, William B. Drake

Kentucky Transportation Center Research Report

This is the third report of observations and operations pertaining to a concrete pavement without the usual transverse joints constructed in the summer of 1949. Report No. 2 which was presented to the Research Committee December, 1949, contained a detailed description of the project, pictures of the class of cracking described, a record of the crack filling operation to December, 1949, and three crack survey reports with a strip map of the project.

The purpose of this report is to present three additional crack surveys taken in 1950 with the additional crack filling operations up to this time. All of …
