Scope: The AASHTO Air Quality Community of Practice May 2012 draft report “Establishing and Coordinating Motor Vehicle Emissions Budgets State-of-the-Practice” recommended an NCHRP study to: “advance the state-of-the-practice for establishing…
Scope: Many states are currently investigating the feasibility of hyraulic fracturing. IN addition to the untold environmental impacts, states are experiencing major road damage due to the size, weight and…
With the advent of the Marine Protection Act, new construction methods are necessary to reduce the underwater noise impacts to mammals. This research would examine alternative construction practices to reduce noise.
RESEARCH PROBLEM STATEMENT In recent years, coal-fired power plants are more frequently utilizing air pollution control technologies that result in fly ash with elevated concentrations of ammonia (referred to herein…
This project will develop, install and field test the effectiveness of new structural BMPs specifically designed to manage runoff near one or two highway bridge decks, e.g., filters and biofiltration…
This study would examine the response of pollinator movement and subsequent gene flow and reproductive fitness between and within rare endemic plant populations that are fragmented by roads by road…
Climate change may affect human health via interactions with air pollutants such as ozone and PM2.5. These air pollutants are linked to climate because they can be both affected by…
Identify and test technologies promising “dust-free” environments. Suggested technologies include water-blasting and abrasive blasting with sponge/grit.
Develop analytical tools and prepare recommendations for highway and rail infrastructure investments that will alleviate bottlenecks and produce environmental, energy and public health benefits. Our proposed collaborative Green Corridor…
Assess management efforts to prevent or slow the spread of exotic plants into and away from roadsides. Research should stratify sites based upon ecosystem, soil fertility and time of disturbance.…
