The main objective of the present study is to evaluate the effectiveness of new additives, to reduce bitumen’s fume emission expelled into the atmosphere, during the processing of asphalt concrete. The new additives act by trapping bitumen’s volatile substances avoiding their release at high temperatures. In this paper, we have been tested the performance of 2 types of mesoporous silica-based additives (AntiSmog 1 and AntiSmog 2). The idea of using these additives to reduce the emission of fumes in bitumen has been submitted as a patent. To quantify and characterize the emitted fumes, thermogravimetry (TGA) and gas chromatography-mass spectrometry (GC-MS) technique have been used. Dynamic Shear Rheology (DSR) has been used to check the rheological properties and the possible sedimentation issues that could occur after the addition of the additives. Keywords: fume; bitumen; mesoporous; thermogravimetry (TGA); gas chromatography-mass spectrometry (GC-MS). Introduction Most definitions of sustainability begin with that issued by the World Commission on Environment and Development (WCED) in 1987: “Sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Moreover, sustainability is often described as a quality that reflects the balance of three primary components: economic, environmental, and social impacts 1 . “Sustainable” in the context of pavements refers to system characteristics that encompass a pavement’s ability to: -Achieve the engineering goals for which they were constructed. - Preserve and (ideally) restore surrounding ecosystems. - Use financial, human, and environmental resources economically. - Meet human needs such as health, safety, equity, employment, comfort, and happiness. All stakeholders in the pavement community from owner/agencies to designers, and from material suppliers to contractors and consultants are embracing the need to adopt more sustainable practices in all aspects of their work, and are continually seeking the latest technical information and guidance available to help improve those practices 2 . Low consumption of energy for production and construction, low emission of greenhouse gases or fumes and conservation of natural resources help to make asphalt the environmental pavement of choice 3-5 . However, the ever-increasing pavement’s loads and the needs for using modified binders and additives to coup the problem of heavy-duty pavements has led to both environmental and economic concerns. In particular, this paper intends to show the benefits of new additives on the emission of bitumen
