Sustainable Solutions
“Livable community” has become the new buzzword in urban planning and transportation circles. With the U.S. population expected to increase by 100 million over the next 40 years, effective coordination of policies related to housing, transportation, energy and the environment will be necessary to ensure quality of life while expediting the flow of both freight and people in the safest and most cost-effective manner. There are, however, some differing ideas on what defines a “livable community”. Defining Livable Communities For much of the last century, roads have played a major role in connecting people to their jobs, schools, places of worship and affordable housing. Transit and intercity passenger rail investments alone cannot begin to meet the nation’s transportation needs. Today, 95 percent of passenger travel in America is by car, motorcycle and truck, and 93 percent of freight by value moves on our highways. The simple fact is that roads are part of the fabric of this nation. To define realistic livability objectives, it is important to: • recognize that 80 percent of the U.S. population lives in rural areas,
Asphalt is a good investment for America. Technological advances in asphalt provide cost-effective and green solutions and advance the goals of livability while protecting the investments that this country has made in our infrastructure. So, what are some of the qualities of livable communities and how does asphalt play a role? Stimulating local economies -- A livable community relies on a healthy local economy and good jobs. The quality of roads and other infrastructure are some of the major considerations that developers use when choosing to do business in a community. In addition, asphalt pavements are built by people who live and work in the areas that they serve. Asphalt jobs are local jobs. Versatility – Asphalt isn’t just for single-driver cars. Buses drive on asphalt. Asphalt is a proven winner for creating track beds that provide a safe base for high speed passenger trains or heavy freight service. Asphalt bike paths and trails provide smooth, safe surfaces while managing fragile ecosystems. Asphalt pavement is also used worldwide as a practical solution to water storage, flood control, erosion, and conservation problems. Asphalt has been approved by the Environmental Protection Agency and used successfully as a primary liner for both sanitary and hazardous-waste landfills. It is also used to line drinking water reservoirs and fish hatcheries in California and Washington. Reducing Noise -- Asphalt is the quiet pavement. Quiet pavement technologies include open-graded surfaces, fine-graded surfaces, and two-layer open-graded pavements. Noise reductions of 3 to 10 decibels are common. Reducing noise by 3 decibels is about the same as doubling the distance from the road to the listener, or reducing traffic volume by 50 percent. Better Water Quality – Managing stormwater is a significant issue in land use planning and development. Porous asphalt pavements allow for land development plans that are more thoughtful, harmonious with natural processes and sustainable. These pavements conserve water reduce runoff, promote infiltration which cleanses stormwater, replenish aquifers, and protect streams. Sustainability Benefits – Asphalt pavements are America’s most recycled product. About 100 million tons of asphalt pavement material is reclaimed each year, and over 95 percent of that total is reused or recycled back into new asphalt pavements. One of the materials most dynamic features is that the asphalt cement can be rejuvenated and the aggregates reclaimed decreasing the demand on virgin materials. It is estimated that recycling of asphalt pavements saves the American taxpayer $1.8 billion per year. It also saves hundred of acres of landfill space each year. Materials from other industries are routinely recycled into asphalt pavements instead of going into landfills. Some of the most common are rubber from used tires, glass, asphalt roofing shingles, and blast furnace slag. Today’s asphalt pavements can be designed as Perpetual Pavements meaning the structure remains intact indefinitely while the top layer requires periodic removal and replacement. Funding Livable Communities • 21,000 individuals die each year in the U.S. as a result of poor roadway conditions (http://www.tripnet.org/RoughRoadsReport_May2009.pdf)on hours a year stuck in traffic at a cost of $78.2 billion a year--$710 per motorist |

Porous Asphalt is King
Porous asphalt is an all-natural material using rocks glued together with asphalt cement, like most standard roads, but with one difference.
