Meeting NYC'S Asphalt Needs (A) - HKS Case Program

Abstract: In Part A of this case, Henry Fulton, the head of New York City's Bureau of Highway Operations proposes that, as a cost saving measure, the city build and operate its own asphalt plant to produce some of the paving material needed each year to resurface its roads, rather than purchasing it from the private sector under a competitive bidding process.

Cool Roofs | Department of Energy

Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles. Standard or dark roofs can reach temperatures of 150°F or more in the summer sun. A cool roof under the same conditions could stay more than 50°F cooler and save energy …

Asphalt Concrete - an overview | ScienceDirect Topics

James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.2.1.3 Asphalt Concrete. Asphalt concrete is commonly called asphalt, blacktop, or pavement in North America, and tarmac in Great Britain and Ireland. Asphalt concrete is known by many different names, examples are: (i) hot mix asphalt (HMA), (ii) warm mix asphalt (WMA), (iii) cold mix asphalt (CMA), (iv) plant mix

Towards improved testing of modern asphalt pavements

Dec 03, 2018 · In addition, for energy saving or other special environmental reasons, asphalt is sometimes produced with warm or even cold mix technology, relying on foam bitumen or bitumen emulsions. However, this is often done at cost of performance and life time since these materials still tend to be inferior to hot asphalt pavement mixtures.
