Sustainability | Free Full-Text | Effect of Precast

The widespread use of solar-reflective concrete pavements can mitigate climatic change and urban heat islands (UHI) by cooling the pavement surfaces that are made of concrete instead of asphalt. The methodology that was followed is based on the comparison between the asphalt and concrete albedo effects in a specific application and area. In this study, we found that a reduction of temperature

Guayule Plant Extracts as Recycling Agents in Hot Mix

The United States of America needs a domestic source of natural rubber. The guayule plant, a woody perennial shrub native to the southwestern U.S. and northern Mexico, has the potential to be that source. Since the early 1900s, high-quality guayule rubber has been extracted from the plant to make tires, etc. However, commercialization of guayule as a natural rubber source in North America has

30 years ago. In many European countries the use of RAP is common practice. Asphalt is re-usable / recyclable and for sustainable development its re-use / recycling should therefore be encouraged. RAP can be re-used to produce new asphalt (in plant and in-situ) and it can be recycled by using emulsions, foamed bitumen and

Asphalt Production Sustainability Lowers Carbon Footprints

The asphalt industry already works with sustainable practices to lower GHGs and keep an already low carbon footprint in check. Recently, a member of the Astec Inc. family, Malcolm Swanson, P.E., gathered information for an 11-page document outlining some of the industry's sustainable practices. Part I of the piece appeared in the July edition and Part II in the August edition of AsphaltPro; here we'll share Part …
