MPC Research Reports Filter by Keyword13 report(s) found with environmental impacts in the keywords field Recently, significant advances have been made in the development of rapid setting cementitious materials for partial-depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed.... Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation... The transportation sector in the United States is currently dealing with several challenges, such as greenhouse gas (GHG) and air pollution emission increases, parking facility costs, congestion, and energy consumption. The present report focuses on the development of an innovative multi-business commute... Mitigating traffic congestion and reducing transportation emissions are among the leading goals of most local, regional, national, and international agencies. Several guidelines rely primarily on strategies that support the following: 1) mixed land-use and transit-oriented developments, 2) multimodal... Millions of cubic yards of concrete and steel used to support the U.S infrastructure may result in a significant negative impact on the environment. CO2 released by construction processes, as well as material production, is taking a substantial toll on the environment. This study seeks to develop a system... Aqueous waste streams produced from commercial, industrial, and municipal processes may be potentially reused for transportation applications. The objectives of this project were to identify potential transportation-related applications for aqueous waste streams available in South Dakota, develop guidance... The First Mile Last Mile (FMLM) challenge garners significant attention as a means to assess the accessibility of the first leg to transit and the last leg from public transit. As a critical barrier to public transit accessibility, the challenge provides many opportunities to closely analyze conditions... This report is Phase II of a previous MPC research project (MPC 02-136) that developed a computer model using a transient, two-dimensional finite volume approach to mathematically describe the thermal response of asphalt pavements due to thermal environmental conditions on an hourly basis. The main objective... This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly... This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures...
