Development Of A Procedure To Identify Aggregates For Bituminous Surfaces In Indiana, Douglas W. Bruner, Jung Chan Choi, Terry R. West
JTRP Technical Reports
Adequate friction resistance is needed to prevent pavement slipperiness and to allow vehicles to stop in a reasonable distance. In stone mastic asphalt surfaces, friction resistance is mainly a function of the interaction between the aggregates exposed at the road surface and the vehicle tires. Performance of the aggregate is reduced over time by wear and polishing as a consequence of vehicular traffic. In this research a method to investigate aggregate performance based on physical, chemical and petrographic factors has been evaluated. The objective was to develop a laboratory method to test Indiana dolomite, limestone, sandstone, and gravel aggregates to …

JTRP Technical Reports
Leaking underground storage tanks are widespread throughout the United States. It is estimated that there are 1.4 million underground gasoline storage tanks in the United States, with as many as 75,000 to 100,000 that may be leaking. In Indiana alone, more than 3,500 of the 15,000 registered underground storage tank facilities have reported leaks. Conventional remediation methods often involve pump-and-treat schemes for contaminated water, and excavation and burial of contaminated soil in hazardous waste landfills. These methods increase the risk of exposure to pollutants for workers and local residents. Furthermore, these methods merely involve the transfer of pollutants from one …

Impact Analysis Of Vehicles On Ozone Generation In The Indianapolis Metropolitan Statistical Area, Robert Bertram Jacko, Ouattara Fatogoma
Impact Analysis Of Vehicles On Ozone Generation In The Indianapolis Metropolitan Statistical Area, Robert Bertram Jacko, Ouattara Fatogoma
JTRP Technical Reports
Motor vehicles are one of the largest emitters of ground-level ozone precursors – volatile organic compounds (VOCs) and nitrogen oxides (NO1) – into the atmosphere. Consequently, the Clean Air Act Amendment of 1990 requires the implementation of transportation control measures in order to reduce ground-level ozone precursor emissions and alleviate the ozone air quality problems. This research investigates the relative effects of motor vehicle emissions of VOCs and NO1 on hourly average concentrations of ground level ozone in the Indiana Airshed Model (UAM-IV). The findings of the research study are presented. This includes the results of the data analyses leading …
Indot Constructability Multimedia System Working Module, Bob G. Mccullouch
Indot Constructability Multimedia System Working Module, Bob G. Mccullouch
JTRP Technical Reports
Constructability can be defined as incorporating knowledge into the design product or designing so it is easier to construct. Transportation facilities have suffered from this problem, with INDOT no exception. The most important feature of any constructability program is capturing field examples, commonly referred to as “lessons learned,” and archiving and retrieving them into future projects that are either similar or have similar conditions in order to eliminate or prevent the same mistakes from occurring again. A mechanism or tool that can perform this task would be a valuable asset for INDOT. A previous JHRP project title “An INDOT Lessons …

Laboratory Study On The Use Of Tire Shreds And Rubber-Sand In Backfilled And Reinforced Soil Applications, Andres Bernal, C. W. Lovell, Rodrigo Salgado
JTRP Technical Reports
Millions of scrap tires are discarded annually in the United States, the bulk of which are currently landfilled or stockpiled. This consumes valuable landfill space, or, if improperly disposed, creates a fire hazard and provides a prolific breeding ground for rats and mosquitoes. The use of tire shreds as lightweight fill material can sharply reduce the tire disposal problem. The present study, based on laboratory testing and numerical modeling examines the feasibility of incorporating tire shreds and rubber-sand mixtures as lightweight geomaterial in embankments and backfills. The growing interest in utilizing waste materials in civil engineering applications has opened the …

Environmental Bioassay Evaluation Of Foundry Waste Residuals, Kenneth Chad Bastian, James E. Alleman
Environmental Bioassay Evaluation Of Foundry Waste Residuals, Kenneth Chad Bastian, James E. Alleman
JTRP Technical Reports
Although the constructive reuse of foundry residuals represents a decidedly beneficial goal with distinct economic and environmental benefits, potential end-users are nonetheless reluctant to use these residuals, given an inherent concern about potential unforeseen environmental liabilities. Results of foundry residual leachate characterization to date strongly suggest that many ferrous foundries are discarding sands whose quality is fully amenable to their future use with embankment construction and related high-volume highway development activities. In order to provide additional assurance as to the environmental impact of foundry residual reuse, the MicrotoxTM bioassay has been used to quantify the response of living organisms (e.g., …

Remediation Of Hazardous Effluent Emitted From Beneath Newly Constructed Road Systems And Clogging Of Underdrain Systems, Ronald Fred Wukasch, Adil Siddiqui
JTRP Technical Reports
The Indiana Department of Transportation uses recycled concrete pavement as aggregate for the construction of highways. The effluent from these pavements has a high pH. The high pH effluent can cause clogging of drains and vegetative kill around the outlet. This project looks into the source of the effluent water, its chemical composition and the approximate duration the problem can be expected to persist. The project also investigates possible methods for reduction of the problem in future installation. The approximate additional cost of these solutions and the problems associated with them are discussed as well.
