| 摘要： | A carbon footprint may be defined as the total amount of greenhouse gases primarily carbon dioxide released into the atmosphere by a particular human activity. A carbon footprint can be a broad measure to be applied to the actions of an individual, a family, an event, an organization, or even an entire nation. It is usually measured as tons of CO2 emitted per year, a number that can be supplemented by tons of CO2-equivalent gases, including methane, nitrous oxide and other greenhouse gases. The Indian road sector is constantly looking for the new technologies and innovations for the improved construction efficiency, conservation of resources, saving in construction cost as well as protecting the environment. The conventional method of road construction for the flexible pavement required significant amount of aggregate, other construction material and energy. UP PWD has adopted the latest technology of road construction including recycling and stabilization of pavement layers resulting in saving of huge quantity of aggregate, bitumen as well as transportation and energy. This paper outlines the case studies of projects executed by UP PWD using emulsion/foamed bitumen as a stabiliser of base layer and the resultant effect of carbon footprint. |
