Accidents On Rural Interstate And Parkway Roads And Their Relation To Pavement Friction, Rolands L. Rizenbergs, James L. Burchett, John A. Deacon, Cass T. Napier

Kentucky Transportation Center Research Report

Friction measurements were made with a skid trailer at 70 mph (31 m/s) on 770 miles (1240 km) of rural, four-lane, controlled-access routes on the interstate and parkway systems in Kentucky. Each construction project was treated as a test section. Accident experience, friction measurements, and traffic volumes were obtained for each. Various relationships between wet-weather accidents and skid resistance were analyzed. Averaging methods were used as a means of developing trends and minimizing scatter. A moving average for progressively-ordered sets of five test sections yielded more definite results. The expression of accident occurrence which correlated best with skid and slip …

Identification Of Hazardous Rural Highway Locations, John A. Deacon, Charles V. Zegeer, Robert C. Deen

Kentucky Transportation Center Research Report

An effective procedure was determined for identifying hazardous rural highway locations based on accident statistics. Multiple indicators of accident experience that are necessary include the number of fatal accidents, the total number of accidents, the number of effective-property-damage-only accidents, and the accident rate. Critical levels of these four indicators should vary from state to state depending on the nature of the local safety improvement program as well as local traffic and roadway conditions and prevailing attitudes toward highway safety. Specific recommendations are given for use in Kentucky. Critical accident rates are established using quality control procedures.

To identify hazardous highway …

Rock Evaluation For Engineered Facilities, D. J. Hagerty, Robert C. Deen, M. W. Palmer, C. D. Tockstein

Kentucky Transportation Center Research Report

The need for comprehensive information on the characteristics and behavior of earth materials has been recognized for many years, perhaps for as long as significant construction has taken place in and on the surface of the earth. In recent years, however, the magnitude and complexity of engineered construction has greatly increased, resulting in a corresponding increase in the need for information on the engineering properties of soil and rock materials, Direct testing of soil and rock can be utilized to furnish necessary information. However, both field and laboratory testing can be extremely expensive, particularly where testing must include applications of …

Adaptation Of Aasho Interim Guide To Fundamental Concepts, Herbert F. Southgate, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

Using 1971 vehicle classification counts and truck weights from nine Kentucky locations, equivalent axleloads (EAL's) were calculated by several methods. Apparent discrepancies led to a review of axleload equivalency factors used to estimate either EWL's (equivalent wheel loads) or EAL's.

Axleload equivalencies are determined as the ratio of the number of repetitions of a standard or reference load to the number of equivalent (damage-wise) repetitions of the load in question. The choice of equivalency factors can result in as much as a 40-percent difference in calculated EAL's. Most of Kentucky's traffic is made up of axleloads less than 80 kilonewtons …

Evaluation And Modification Of The Traffic Noise Prediction Procedure For Kentucky Highways, Kenneth R. Agent, Charles V. Zegeer

Kentucky Transportation Center Research Report

Approximately 270 noise-level recordings were obtained at 39 highway sites and compared with the noise-level predictions obtained by the procedure outlined in NCHRP Report 117. The measured noise levels were computed in terms of the A-weighted L₁₀ value (level exceeded 10 percent of time) and then compared to the predicted noise levels. A significant discrepancy was found between predicted and measured noise levels; generally, the predicted values exceeded the measured values. Average error per location was 4.8 dBA; the maximum error was 13 dBA. A nomograph was devised to correct the predicted value; this nomograph involves observer-to-roadway distances, truck …

Fatigue Analysis From Strain Gage Data And Probability Analysis, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

The Central Bridge over the Ohio River between Newport, Kentucky, and Cincinnati, Ohio, was completed in 1891 and in 1972-73 was considered to be in danger of fatigue failure. A series of investigations were undertaken to determine the likelihood of failure and to estimate the time of probable failure. During the investigation, a methodology was developed to determine fatigue damage from a probability analysis of traffic data by reconstituting or synthesizing the load (traffic) history of bridges. Strain gage data obtained with Prewitt scratch gages and SR-4 resistivity gages were used to evaluate fatigue damage incurred by the Central Bridge.

Relationships Between Roadway Geometrics And Accidents, Kenneth R. Agent, Robert C. Deen

Kentucky Transportation Center Research Report

Statewide average and critical rates of accidents were determined from 1970-1972 Kentucky accident records for each type of rural highway. Accident data, obtained from state police computer tapes, were summarized to give the number of accidents on each highway type as well as information on accident severity, road surface conditions, light conditions, road character, and type of traffic control. Four-lane undivided highways had the highest average accident rate; parkways (toll roads) had the lowest rate. The severity of accidents was related to types of accidents, highways, and traffic control and to safety belt usage. Accidents involving pedestrians were the most …

Highway Pavement Maintenance Costs And Pavement Type Selection, Donald C. Newberry Jr., Jesse G. Mayes, James H. Havens

Kentucky Transportation Center Research Report

A long-term analysis of pavement maintenance cost has been performed. The analysis does not include construction or resurfacing costs. The sample of pavement sections investigated were chosen to best represent the entire state. These sections were classified by pavement type; either bituminous concrete, portland cement concrete, or composite. The cost per lane mile (kilometer) per year was calculated for each pavement type by year and by age of pavement. Apparent differences in pavement maintenance costs between the two basic types of pavements were adjudged insignificant from the standpoint of determining pavement type. Because of poor or erroneous cost reporting, actual …

Bridge Decks Constructed For Increased Durability, Assaf S. Rahal

Kentucky Transportation Center Research Report

The experimental features incorporated in this study were compaction, brooming, and hi-layered construction. Broomed surfaces initially exhibited a higher skidding resistance than non-broomed surfaces: broomed surfaces, however, wear more rapidly. No conclusive evaluation could be made at this time of the bilayered system and of tests made on the concrete cores. Electrical measurements made on the decks indicated there was no active corrosion of the steel.

Effects Of The Energy Crisis On Traffic In Kentucky, Kenneth R. Agent, Donald R. Herd, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The Arab oil embargo in mid-October 1973 curtailed availability of gasoline. Fuel conservation measures resulted in reduced travel and decreased traffic speeds. On March 1, 1974, posted speed was set at 55 mph on rural highways in Kentucky. Traffic volumes, speeds, and accidents for the rural highway during the period known as the "energy crisis" and its after effects were compared to the corresponding period a year earlier.

Traffic volumes began to decline in December 1973 but began to rise again in March 1974. Total travel in the seven months through June 1974 decreased by 3.5 percent; traffic increased by …

Experimental Portland Cement Concrete Shoulders Design And Construction, James H. Havens, Assaf S. Rahal

Kentucky Transportation Center Research Report

Kentucky's first portland cement concrete shoulder project was conceived in 1970 and was inspired by the Portland Cement Association's issue Concrete Shoulders for Safe Modern Highways, Concrete Report, 1970, and FHWA's Informational Memorandum CMPB-17-70, Experimental Project for the Evaluation of Portland Cement Concrete Shoulders Adjacent to Concrete Mainline Pavement; Project Prospectus, National Experimental and Evaluation Program; May 12, 1970. It was expected that at least two states in each region would participate in the national program. A 3.442-mile section of US 31 W, between Radcliff and Tiptop, beginning at the intersection of US 60 and extending southward, …

Skid Resistance Studies In Kentucky (An Overview – 1974), James H. Havens, James L. Burchett, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

"To free Kentucky of slick roads" is the high goal toward which Kentucky has been striving since 1950's. A very capable fellow engineer used to say that there was more satisfaction in being able to take down a Slippery When Wet sign than in erecting one.

Considerable effort has been devoted to the development and adaptation of improved methods of skid resistance testing and to the standardization of testing devices (1, 2, 3, 4). Methods of tests have included the NCSA friction wheel (bicycle wheel), automobile deceleration, skewed-wheel (skewed front-wheels of an automobile), skidding automobile, and the skid-test …
