Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.

KWRRI Research Reports

The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

Pavement Slipperiness Studies, James L. Burchett Jr., Ronalds L. Rizenbergs

Kentucky Transportation Center Research Report

Studies of pavement skid resistance in Kentucky have been in progress since 1956. In 1964, an extensive investigation into the use of an automobile as a testing tool was undertaken and an interim standard method of test was selected. Since then, investigations with the device have continued, both to facilitate meaningful interpretation of skid-test data and to evaluate the skid resistance performance of pavement surfaces.

Variables associated with the testing device, procedures and pavement surfaces were investigated. Several paving projects were tested to determine the number of sites required to obtain a representative result. It was found that on most …

Freeze-And-Thaw Phenomena In Concretes And Aggregates, James H. Havens

Kentucky Transportation Center Research Report

This report summarizes several years of research relating to damage to concrete and aggregates undergoing freezing and thawing. Basic principles involving freezing and attendant pressures are considered. Application of these principles to the evaluation of concrete was accomplished in experiments on concrete having low and high air contents. The effects of air entrainment upon freeze-thaw resistance were demonstrated.

Freeze-thaw characteristics of saturated aggregates relative to their physical properties such as porosity, absorption and bulk specific gravity were studied by submerging individual particles in pre-chilled mercury. Pressures associated with popouts in concrete were monitored and are presented along with accompanying theoretical …

An Investigation Of Low-Strength Concrete And Resulting Structural Failure In A Bridge Deck, James H. Havens

Kentucky Transportation Center Research Report

This investigation concerns the discovery of weak concrete in a portion of the deck of the Elkhorn City bridge, APD 640(4), within a year after it was opened to traffic. The deck concrete was placed between April 14 and June 14, 1968. The bridge serves heavy coal-trucks traffic. Failures occurred in the eastern-most span (No. 5) in April or May of 1969, Undoubtedly, the heavy loading contributed to early disclosure of defective concrete.

A preliminary investigation was made in May 1969, and reported by memorandum May 21, 1969. The bottom third or half of concrete in the affected portion, Span …

Locating And Tracing Seepage Water In Unstable Slopes, Yasin A. Alkhoja, Gordon D. Scott

Kentucky Transportation Center Research Report

With the increase in modern highway construction, the occurrence of landslides has been growing proportionally due to the use of deeper cuts and higher fills. It has been observed that landslides on highways often occur in fills on hillsides. Accumulation of water in the embankment, usually seeping from a nearby hill, may reduce the shear strength of the embankment soil and result in failure at a later time. Many landslides on Kentucky highways have occurred a few years after construction and obviously have been caused by the gradual weakening of the embankment due to a damming and accumulation of water. …

Slip-Form Paving, Kerry P. Magan

Kentucky Transportation Center Research Report

The proper placement, consolidation, and finishing of low-slump concrete without the aid of pre-erected side, forms has been widely acclaimed as an economical and effective procedure in the construction of portland cement concrete pavements. This construction procedure, commonly referred to as slip-form paving, depends upon the ability of low-slump concrete to remain in place after consolidation and removal of forms.

Slip-form pavers differ from conventional pavers in that no fixed side forms are required inasmuch as the slip-form paver has side forms that advance with the machine. Concrete is merely deposited on the prepared subgrade in front of the machine, …

Final Performance Report On Experimental Use Of Thermoplastic Pavement-Striping Materials, Assaf S. Rahal, Ronald D. Hughes

Kentucky Transportation Center Research Report

This study was undertaken in order to: 1) evaluate the performance of thermoplastic striping materials, 2) compare their performance on both portland cement concrete and bituminous concrete pavements to that of conventional traffic paints, and 3) to evaluate the economics of thermoplastics in terms of cost per mile per day of useful life. The performance of two brands of thermoplastic striping materials and conventional traffic paints applied at nine test sites in both rural and urban areas is reported herein. Application procedures, site locations, repair histories and materials specifications are included. Accumulative costs for each material at all sites for …

Slurry Seal Maintenance Applications, Robert L. Florence, Herbert F. Southgate

Kentucky Transportation Center Research Report

A slurry seal mixture consists of graded fine aggregate (normally minus 3/8-inch material), mixing grade emulsified asphalt (SS-1 or SS-lH), and water. The water is added to aid in mixing and to provide a free-flowing consistency so that the mixture can be spread in thin layers on the surface of an existing pavement. After the mixture is spread, the water evaporates and the remaining material, aggregate and base asphalt, forms a thin seal on the pavement surface which resembles a fine-grained asphaltic-concrete surface. As a result of the free-flowing consistency and the fineness of the aggregate, a slurry mixture readily …
