Environmental impact of concrete - Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

Recovery Story: Kids Kick Asphalt Out of the School Yard

More pavement leads to more polluted stormwater. Pollution in the area's water sources is a significant contributing factor to some of the Puget Sound's most prominent ecological problems, including declining salmon populations and the poor health of the critically endangered Southern Resident killer whales.

Contamination of stormwater from engine leaks or conducted experiments on a PAP (porous asphalt pavement) installation. Results indicated a 62% reduction in the peak tlow when compared to a conventional asphalt paving installation. The peak tlow occurred capacities of the sites were determined and the effect of age of the installation

Leaching of Pollutants from Reclaimed Asphalt Pavement

The construction and expansion of asphalt roadways results in the production of a large amount of milled asphalt also known as reclaimed asphalt pavement (RAP). A major fraction of this RAP is recycled by incorporation into a new asphalt mixture. At times, however, a large amount of this material may require other forms of management.

PDF Stability and Resilient Modulus of Porous Asphalt

Porous Asphalt (PA) is known as a highly permeable asphalt surface that design to be permeable pavements for stormwater control and reduce the stormwater runoff. However, the structure is subjected to damage from cracking, rutting, stripping, and rapid aging under the effects of repeated vehicle loading, hot climates, and heavy rainfall.

Stormwater Runoff Takes Bite Out of R.I.'s Vulnerable

Stormwater runoff, like tidal action and storm surge, erodes waterways and increases coastal flooding. It is, among many other things, stressing the Ocean State's prized natural resource. Narragansett Bay's 700 billion gallons of water cover 150 square miles, and its 1,700-square-mile watershed nurtures thousands of species of flora and fauna.

Although these costs are higher than the cost of installing asphalt per square foot, permeable pavement can cost less than full conventional concrete stormwater management systems 18. Permeable pavement projects are particularly cost effective where land values are high and where flooding or icing is a problem 1 .

New studies: Toxic asphalt sealants threaten kids, cause air pollution. When you think of pollution, you might picture an industrial center like Camden, N.J., or Jersey City. But new research shows that when it comes to a potent class of cancer-causing toxic chemicals, many American parking lots are a lot worse.

Parking Lot Sealcoat: A Major Source of Polycyclic

Collaborative studies by the City of Austin and the U. S. Geological Survey (USGS) have identified coal-tar based sealcoat—the black, shiny emulsion painted or sprayed on asphalt pavement such as parking lots—as a major and previously unrecognized source of polycyclic aromatic hydrocarbon (PAH) contamination.

Coal-Tar Sealcoat, Polycyclic Aromatic Hydrocarbons, and

Coal-tar sealcoat is a type of sealant used to maintain and protect driveway and parking lot asphalt pavement. Coal-tar sealcoat typically contains 20 to 35% coal tar pitch, a byproduct of the steel manufacturing industry, which is 50% or more polycyclic aromatic hydrocarbons (PAHs) by weight.
