The goal of this project was to develop a chemical admixture that would reduce the need for wintertime thermal protection of freshly placed concrete. Chemicals were investigated for their ability to promote strength gain in concrete cured below 0 degrees C. The project was carried out in five phases. Phase 1 evaluated existing and new admixtures. P

PALS is an acronym for Program to Analyze Loads Superheavy. Gross vehicle weights associated with superheavy load moves range from 1112 kN to more than 8896 kN and include loads like dragline components, offshore pipe laying equipment, oil pressure vessels, and electric transformers. The number of superheavy load permit applications has increased o

The objective of this research effort was to develop and test a recommended methodology to estimate the economic impact of median design. This report summarizes the results, conclusions, and recommendations for the first year of this four-year study. The first test of the methodology was conducted within the Bryan District of the Texas Department o

The primary focus of the “Enhanced Proximity Warning System” (EPWS) is to provide a cost effective means to improve safety of railroad operations, with the ability to implement on an incremental, building block approach. The main safety objective of EPWS is for prevention oftrain collisions, but other safety functions, such as compliance with opera

The persistent and in many parts of the world rapid motorization of transport is intensifying global dependence on petroleum. Transportation?s global oil dependence poses real energy security risks for the first few decades of the 21st century, at least. At the same time, the world economy is in no danger of ?running out of oil? during the next cen

This working paper describes the process used to develop land market variablesfor use by TRANUS in the Transportation and Land Use Model IntegrationProgram (TLUMIP). One of the key variables developed during this phase of theproject is the mean land cost for each land market sector. This paper discussesother variables and addresses other issues but

Greater population density is associated with decreasing annual miles driven, greater bus availability, decreased dependency on single occupancy vehicles and increased use of transit. The private automobile is still the dominant mode of travel although African Americans, Asians and Hispanics are slightly more likely to use other modes of transporta

This manual is a model to be followed by bridge paint inspectors on how to perform inspection duties properly. Given that most of today's bridge-paint work is being done on existing steel, this manual is geared toward people working in the field on existing steel. The manual is broken down into three primary sections. The first section covers the p

Finite element models for the Shippingport Vertical Lift Bridge over the Illinois River at LaSalle were created using a three-web design for the sheaves. The models used a linear load distribution along the periphery of the sheave. Models were created that include details of the outer web, inner web, and hub. Using an analysis developed at the Univ

This Integrated Logistics Support Plan (ILSP) serves as the master logistics planning document that describes necessary logistic activities, assigns responsibility for those activities, and establishes a schedule for completion. It is one of the initial planning documents required IAW COMDTINST M4150.2D, and is a living document which will be updat

This report results from a task implemented in the fall of 1996 to assist the National Transuranic Program Office of the Department of Energy/ Carlsbad Area Office (DOE/CAO) in establishing data quality objectives (DQOs) for the radioassay of Remote-Handled Transuranic (RH-TRU) waste. As part of the task a draft report was submitted to DOE/CAO on J

Effective communication among air safety professionals is only as good as the information being communicated. Data sharing cannot be effective unless the data are relevant to aviation safety problems, and decisions based on faulty data are likely to be invalid. The validity of aviation safety data depends on satisfying two primary characteristics.
