Deck construction is one of the last major hurdles left to achieve the concept of a totally prefabricated bridge system. In the last decade, several bridge deck panel systems have been developed and used in bridge replacement projects in the United States. In this study, the researchers were directed to collect primarily information related to full

This report deals with formulations of the effects of errors in the measurement of slant range, azimuth, and altitude on master plane representations of target position in an air traffic control system supported by a multitude of surveillance radars. It is concerned with the case in which such representations are based on the metho<1 of stereograph

In this synthesis study, information related to full-depth precast deck systems has been collected and analyzed in order to facilitate implementation of full-depth precast deck systems in the state of Indiana. Nine full-depth precast deck systems were identified in the literature review. For girder bridges or similar, a full-depth precast, prestres

The objective of the study was to evaluate top-down cracked pavements and assess their structural capacity as well as study in-place materials to propose the best identification of distress type, material selection, and rehabilitation methods to be used in Indiana. Research involved evaluating three surface cracked pavements during 2002 and 2003. A

The research involved evaluating three surface cracked pavements during 2002 and 2003. A 500m section of I-65 North of Lafayette was chosen as the first site (designated as Site 1), an I-65 section in downtown Indianapolis was the second site (Site 2), and US-421 in Madison was the third site (Site 3). Site 1 had 11-year-old pavement, Site 2 had 12

The closure of roadways for new pavement, overlays, or removal and replacement applications constantly causes traffic congestions. To minimize the effects of traffic congestions, the study is intended to assess the feasibility of using Precsat Concrete Pavement (PCP) method in INDOT pavement construction. The research investigated the state-of-the-

Recent advances in composite materials for civil engineering have created interesting possibilities for replacing conventional structural forms with components made out of fiber reinforced composite materials. Composite materials offer several advantages over conventional materials such as a superior strength/weight ratio, a better stiffness/weight

This program examines the applicability of a proprietary blending process to blending antimisting additives in JET A aviation fuel. The first phase of the program covers Use of the process with a high molecular weight polyisobutylene. The second phase covers the use of the process with Imperial Chemical Industries, Ltd.'s proprietary polymer, FM-9.

This publication contains a history of cockpit visibility surveys which were conducted to measure and record aircraft (General Aviation, Transport, Helicopter, Military) cockpit visibility. Many of the aircraft were involved in midair collisions, accident investigations, research and development, and the design up through production implementation.
