Remediation Of Aromatic Hydrocarbons In Low Permeability Soils: Updating The Remediation Decision Tree (Synthesis Study), Inez Hua, Andy Hopf

JTRP Technical Reports

Because of the large number of technologies for in situ remediation, the very different types of contaminants to which these technologies are applicable, and the wide range of field conditions, it can be difficult to choose an optimal technology for a specific site. Sorting and prioritizing the various factors which contribute to the success of a particular clean-up can be daunting. Furthermore, non-technical factors, such as those in the legal, political, or financial realm, may also influence which technology is ultimately chosen. Most in situ treatment methods are effective in permeable soil. However, much of Indiana soil is low-permeability, so …

The Indiana Department of Transportation (INDOT) has installed RPMs on selected roadway sections primarily as position guidance devices in order to better guide drivers in night conditions. In Indiana, RPMs are installed on all interstate highways and multilane divided highways. However, RPMs are used on only a few of the Indiana’s two-lane highways. …

Advanced Compaction Quality Control, Carlos Zambrano, Vincent P. Drnevich, Philippe L. Bourdeau

JTRP Technical Reports

This Synthesis Study gathered the current knowledge on the topic of Intelligent Compaction and provides INDOT with recommendations for action. It appears that totally embracing this technology at this time is premature. On the other hand, it also appears that prudent use of this technology could provide tremendous benefit-to-cost ratios over the long term and position Indiana as a leader among the States in adopting it. After examining the technological developments over the last decade it is concluded that Intelligent Compaction is a near certainty in the future. The big question is: When is the right time to begin working …

This is followed by the calibration of fully-constrained gravity models for the flow of these commodities. Using modal share data from the CFS the generated traffic is divided between the various modes. This project looked primarily at the highway sector and used digital representations of these networks for traffic assignment purposes. A very detailed Indiana …

Primary Emergency Routes For Transportation Security, Srinivas Peeta, Georgios Kalafatas

JTRP Technical Reports

Security threats and natural disasters (such as hurricanes and cyclones) are events that have historically led to large scale evacuations. Evacuation operations are strongly characterized by traffic volumes that substantially exceed the network capacity, and consequently, the potential for severely degraded network performance. The efficient management of evacuations entails long-term planning and real-time operational paradigms that are, ideally, integrated. This study focuses primarily on the planning aspects of evacuation, while providing important insights for operations. Identifying capacity as a key element to efficient evacuation, the evacuation planning seeks to determine links where additional capacity is desired, as well as the …

Implementation Of A Non-Metallic Reinforced Bridge Deck, Volume 2: Thayer Road Bridge, Robert J. Frosch, Ali Cihan Pay

JTRP Technical Reports

The primary maintenance problem with bridges in Indiana has been deterioration of the concrete deck which is often related to corrosion of the reinforcing steel. While a corrosion protection system consisting of epoxy-coated reinforcement in combination with 2-1/2 in. of Class C concrete cover has been used in Indiana, research and experience have demonstrated that this system can be compromised. As an alternative solution to the corrosion problem in reinforced concrete, fiber reinforced polymer (FRP) bars which are corrosion resistant can be provided as reinforcement. This research was divided into two phases directed towards the implementation of a nonmetallic reinforced …

Family Of Compaction Curves For Chemically Modified Soils, Radha Krishna Daita, Vincent P. Drnevich, Daehyeon Kim

JTRP Technical Reports

Lime and Lime Kiln Dust (LKD) are widely used for modifying/stabilizing pavement subgrades. The addition of lime or LKD involves chemical processes that are dependent on many parameters. For natural subgrades, quality control is based on moisture and unit weight requirements using manual interpolations of one-point test data on a family of curves. For modified soils, moisture and unit weight measurements are insufficient for quality control and other tests must be considered. Various possible quality control methods for LKD-modified subgrades were evaluated. This research produced an Excel-based program to automate the generation of a family of curves and one-point data …

Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock

JTRP Technical Reports

In 1997 the Indiana Department of Transportation adopted the Superpave mixture design method and attendant specifications for hot-mix asphalt pavements. Prior to Superpave, the Indiana Department of Transportation aggregate frictional requirements were based on average daily traffic volumes and were divided into low, medium, and high volume categories. With the implementation of Superpave in Indiana, aggregate frictional requirements were reassigned to categories based on equivalent single axle load values. The purpose of the research is to determine whether average daily traffic or equivalent single axle load has a greater effect on the frictional resistance of a hot-mix asphalt pavement, to …

An Analysis Of Seismic Hazards In Indiana, Jennifer Haase, Robert Nowack, Chi Hyun Park, Alison Hunyar, John Hill, Michael Hamburger

JTRP Technical Reports

Current USGS probabilistic seismic hazard estimates (Frankel et al., 2002) show a higher seismic hazard in southwestern Indiana than for the rest of the state. This is expected based on past work documenting large pre-historic events in the Wabash Valley, and also based on isoseismal levels of shaking from the New Madrid 1811-1812 earthquakes. When assessing the hazard on a county by county basis, the local soil conditions produce amplification of shaking in regions with soft or unconsolidated sediments relative to firm-rock sites. We have reproduced the probabilistic seismic hazard calculation following the USGS methodology for the state of Indiana …
