Hot-Mix Coal-Tar Concrete Pavement, Donald C. Newberry Jr., Jerry G. Rose

Kentucky Transportation Center Research Report

The principle objectives of this research were:

1. To compare the economics and performance of coal tar to asphalt cement;
2. To develop reliable coal-tar construction specifications;
3. To familiarize personnel with coal-tar construction; and
4. To implement Section 201, Subsection d and e, of the Appalachian Regional Development Act of 1965.

To accomplish these objectives, a 6.6-mile experimental section utilizing coal-tar (RT-12) concrete base and surface and 5.1-mile and 5.7-mile control sections utilizing asphalt (PAC-5) concrete base and surface were placed on relocated KY 15 in Perry, Knott, and Letcher Counties during the 1969 and 1970 construction seasons. The pavement consisted of an …

Experimental Installations Of Impact Attenuation Devices, Bruce S. Siria, William M. Seymour, Don L. Cornette, James L. Miller

Kentucky Transportation Center Research Report

The expanding system of limited access, multilane highway facilities in the United States has enhanced traffic service between many varied origins and destinations. As a result, these facilities have not only reduced travel times and travel costs, but have generated additional travel by virtue of their technological splendor. The increasing dominance of multilane highways in terms of percentage of total vehicle miles travelled has produced a revolution in highway engineering philosophy. Higher design speeds, increased lane widths, lateral separation of opposing traffic streams, absence of passing restrictions, and increased traffic capacities were attributes intuitively sought. An ironic result is the …

Development Of An Electronic Means Of Weighing Vehicles In Motion, Ben W. Carr Jr., Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

An in-stream weighing platform was designed and installed in the eastbound lane of I 64 and 75 near Lexington, Kentucky. The broken-bridge scale platform was designed with the outer edges of the two sections supported on hinges and contiguous edges supported by two 20,000-pound capacity load cells. The assembled scale measures 4'-6" x 10'-1/2" with a total weight of about 2,000 pounds.

The electronics developed for the system included digitizing circuitry which processed the load cell signals and recorded the data on digital magnetic tape. Computer processing of the field data produced tabular information on vehicle speed, axle spacing, number …

Experimental Concrete Pavement Containing Fly-Ash Admixtures [1971], James R. Philpot

Kentucky Transportation Center Research Report

The report enclosed is somewhat routine inasmuch as it documents a repeat of a portion of an earlier experimental project. The previous project was on Poplar Level Road; our final report was dated July 1966 (KYHPR-64-1). Special Provision No. 70 was used also on the Jefferson Freeway project. However, there was no "control section" involved in the current project. The Jefferson Freeway project was authorized by the BPR under P.P.M. 60-2 only (now PPM 20-6.3).

The most significant findings from both projects concern the water requirements the concrete containing the fly-ash admixture. Whereas laboratory tests indicated reasonable expectations of a …

The Generation Of Flood Damage Time Sequences, John P. Breaden

KWRRI Research Reports

There is a need in water resources planning to develop a procedure for determining the time pattern in which flood damages occur as a function of the rise and fall of the flood hydrograph. The widely-used approach for estimation of flood damages does not take into account the fact that the frequency of the annual flood peak may not be the same as the frequency of the total annual flood damages. As examples, several small storms during the year may do more damage than a single larger storm, or flood damages may be reduced by a reduction in flood duration …

Establishment Of Wood Plants On Roadsides (Southeastern Kentucky), Samuel E. Whitaker

Kentucky Transportation Center Research Report

Recommendations for woody plant materials to be used in direct seeding are given on the basis of the plant's ability to regenerate from roots and natural seedings. Species are recommended for each of the relief and drainage subdivisions of the study area, southeastern Kentucky. Plant information on recommended native species has been summarized to provide basic data relevant to or needed by the highway landscape designer in selecting native plant combinations to be used in direct seeding.

Operational Effects Of Auto-Utility Trailer Combinations On Rural Highways In Kentucky, Bruce S. Siria

Kentucky Transportation Center Research Report

An analysis of accident records indicated that A-UT combinations are involved in a disproportionately high number of traffic mishaps. Locations which have a history of accidents involving A-UT vehicles indicated that differential crosswinds and unanticipated driving maneuvers contribute to driver loss of control. A-UT combinations contributed to the fatigue loss in pavement life approximately 50 percent as much as single-unit, two-axle, six-tire trucks (per vehicle). In general, this vehicle type constituted approximately three percent of the total traffic stream. Analysis of speed distributions indicated an equivalency factor for A-UT combinations equal to that for trucks for similar roadway types and …

Continuously Reinforced Concrete Pavement, James H. Havens

Kentucky Transportation Center Research Report

A sampling-type crack survey was made in July 1969; 200 feet in each 1000 feet were sampled. The average interval between cracks was 5.78 feet. Paving was completed in late 1968. The average crack interval in July 1970 was 4.14 feet. The 1970 survey was also a sampling type.

It is apparent that cracking approached maturity or equilibrium during the first year. Apparently, too, most of the cracking occurred during the first few weeks after construction – which suggests curing shrinkage as a contributory cause. A discussion of the significance of time and temperature will follow the presentation of other …

Evaluation Of Cored Specimens From Timber Caisson Beneath Pier No. 2 Of The Us 25 Bridge Over The Ohio River Between Covington And Cincinnati, James H. Havens, Assaf S. Rahal

Kentucky Transportation Center Research Report

Pier No. 2 of the former C&O Bridge at Covington is off-shore from the Kentucky side of the Ohio River. It was built in 1887. In 1927, this pier was extended downstream to support a new railroad bridge. The other three piers remained independent. The original structure was then converted to highway use and was purchased by the Commonwealth of Kentucky in 1937. In 1968, an engineering analysis of the superstructure indicated critical deficiencies in terms of "safety factors", and the bridge was closed to all traffic. Subsequently, various plans for reconstruction came under consideration. Of greatest significance here is …

Relationship Between Soil Support Value And Kentucky Cbr, Tommy C. Hopkins

Kentucky Transportation Center Research Report

Three slightly different correlations between Kentucky CBR's and the AASHO Road Test soil support values were developed. The first relationship was made by assuming a logarithmic scale between Kentucky CBR's of 5.2 and 100, which corresponded to values on the soil support scale of 3 and 10, respectively. The Kentucky CBR of 5.2 was determined by performing tests on the AASHO road subgrade soils. For practical purposes, the AASHO Road Test crushed stone base material was assumed to be a "100 percent CBR material" (this assumption was based on CBR data previously reported by Shook and Fang). The second correlation …
