The Effects Of Bag House Fines And Incomplete Combustion Products In A Drum Drier On The Characteristics Of Asphalt Paving Mixtures, Phase Ii, Jyh-Dong Lin, Leonard E. Wood Jan 1990

The Effects Of Bag House Fines And Incomplete Combustion Products In A Drum Drier On The Characteristics Of Asphalt Paving Mixtures, Phase Ii, Jyh-Dong Lin, Leonard E. Wood

JTRP Technical Reports

An extensive laboratory study of the asphalt paving mixtures containing baghouse fines has been conducted through seven sets of experimental designs to characterize the performance of pavement. Marshall size specimens of asphalt paving mixtures with different kinds and amounts of baghouse fines were fabricated using the gyratory testing machine. The following techniques were used to evaluate the influence of the various variables upon mechanical properties such as: gyratory parameters, resilient modulus, indirect tensile strength, indirect creep, and Hveem stability tests to evaluate their mechanical properties. In addition, in the asphalt paving mixtures, asphalt cement was replaced with baghouse fines in …


The Effect Of Baghouse Fines And Incomplete Combustion Products In A Drum Drier On The Characteristics Of Asphalt Paving Mixtures - Phase I, Thomas Binn Nelson, Leonard E. Wood Jan 1990

The Effect Of Baghouse Fines And Incomplete Combustion Products In A Drum Drier On The Characteristics Of Asphalt Paving Mixtures - Phase I, Thomas Binn Nelson, Leonard E. Wood

JTRP Technical Reports

The major purpose of this study was to use the high pressure-gel permeation techniques to evaluate the changes in asphalt subjected to different mix production parameters, including plant type, level of aging and fuel used in the burner of the drier. Additional objectives were to establish correlations between physical parameters of asphalts and their chromatographic parameters, and to determine whether the HPGPC technique could be used to detect burner fuel contamination in the mix produced by asphalt plants.

This study determined that the HPGPC technique is an excellent comparative analysis tool, capable of detecting changes in the aging of asphalt, …


An Accelerated Testing System To Determine Percent Crushed Aggregate Requirements In Bituminous Mixtures, Thomas D. White, J. M. Abers, John E. Haddock Jan 1990

An Accelerated Testing System To Determine Percent Crushed Aggregate Requirements In Bituminous Mixtures, Thomas D. White, J. M. Abers, John E. Haddock

JTRP Technical Reports

With increase in axle loads, tire pressures and volume of truck traffic there has been an increase in the rate of which bituminous pavements are exhibiting rutting. Because resistance to rutting can be increased by the addition of crushed aggregate, a need exists for a method of determining what amount of crushed material is required and the characteristics of that crushed material to optimize performance and economy.

The Accelerated Testing Facility will be located at the INDOT Research Division Facilities in West Lafayette, Indiana. A pit within the Test Facility will allow prototype scale pavement sections to be installed. An …


The Effects Of The All-Red Clearance Interval On Intersection Accident Rates In Indiana, Brian Alan Roper, Jon D. Fricker, Kumares C. Sinha, Robert E. Montgomery Jan 1990

The Effects Of The All-Red Clearance Interval On Intersection Accident Rates In Indiana, Brian Alan Roper, Jon D. Fricker, Kumares C. Sinha, Robert E. Montgomery

JTRP Technical Reports

The research reported is an evaluation of all-red clearance intervals as the second phase of a project involving traffic signal operation. The first phase of the project dealt with leading versus lagging left turn signal phasing. The study analyzed both the short-term and long-term effects of all-red interval on accident rates in Indiana using accident records for the years 1981 to 1987. The results contradict those of previous studies. Statistical tests indicated that all-red clearance intervals did not cause a reduction in accident rates at the intersections studied in Indiana.


Speed Trends On Indiana Rural Interstate Highways, David L. Cochran Jan 1990

Speed Trends On Indiana Rural Interstate Highways, David L. Cochran

JTRP Technical Reports

This report includes calendar years 1983 through 1989, and is the second speed survey made exclusively of rural interstate data. All data were retrieved from locations that have been exempted from the 55 MPH Speed Compliance Certification Program.

The results of this study show that all vehicles on all Indiana rural interstate highways, had an average speed of 65.6 mph in 1989. This is 1.6 mph higher than the 1988 average speed of 64.0 mph, and 1.7 mph higher than the average speed of 63.9 mph during the 1987 calendar year. In addition, comparing Statewide speed versus vehicle length during …


Engineering Soils Map Of Henry County, Indiana, Barbara I. Schmidt Jan 1990

Engineering Soils Map Of Henry County, Indiana, Barbara I. Schmidt

JTRP Technical Reports

The report completes a portion of the long-term project concerned with the development of county engineering soils maps in the State of Indiana. The soils mapping of Henry County was done primarily by the analysis of landforms and associated parent materials as portrayed on stereoscopic aerial photographs. Valuable information for soils was obtained from publications of the Soil Conservation Service, United States Department of Agriculture. Test data from roadway and bridge projects was obtained from the Indiana Department of Transportation. Soil profiles for the landform/parent material areas mapped are presented on the engineering soils map, a copy of which is …
