Life Cycle Assessment (LCA) of Rubber Modified Asphalt Substantial potential for environmental impact when replacing conventional asphalt with less thick RMA Based purely on pavement, life cycle impact of PMA and RMA are comparable; small carbon emission improvement for RMA Indirect benefits of RMA, especially reduced concrete in noise barriers, can generate outsized life cycle improvements
Life Cycle Assessment of Asphalt Pavement Maintenance Chui et al , (2007) performed a study to evaluate the environmental impact of rehabilitating pavement using different recycled materials that are traditional hot-mix asphalt, RAP, asphalt rubber, and glassphalt
Life Cycle Assessment of Asphalt Mixtures in Support of an . . . The goal of this life cycle assessment (LCA) is to support the Product Category Rule (PCR) for Asphalt Mixtures for the environmental product declaration (EPD) program hosted by the National Asphalt Pavement Association (NAPA) The PCR addresses United Nations Standard Products and Services Code (UNSPSC) 30111509: Asphalt Based Concrete
LIFE CYCLE ASSESSMENT OF ROAD PAVEMENTS CONTAINING CRUMB RUBBER FROM . . . ABSTRACT Management of the huge quantity of end‐of‐life tires (ELTs) collected every year leads to several options among which the preferable ones seem to be recycling and reuse, that allow the high quality of component materials to be fully exploited In the area of road pavements a good example of this type of approach is provided by the technologies (“wet” and “dry”) which
Research on the rubber-asphalt mixtures based on the GTM design method In order to support a policy disclosure to this recycled material, the evaluation of the environmental impacts connected to the life cycle of the asphalt rubber is essential and Life Cycle Assessment is a holistic tool which allows for the evaluation of the overall impacts of the road life cycle and of its critical spots
Life cycle assessment applied to bituminous mixtures containing . . . This paper focuses on Life Cycle Assessment (LCA) of different types of road paving technologies based on the use of bituminous mixtures containing recycled materials such as crumb rubber from end-of-life tires and reclaimed asphalt pavement Analyses were carried out by considering different scenarios which stem from the combination of production, construction and maintenance operations, and
Integrated Sustainability Assessment of Asphalt Rubber Pavement Based . . . Though the environmental impact variables in a pavement life-cycle are complicated, some sustained efforts have been made to minimize the environmental burdens from pavement projects, for example, many recycled materials, such as reclaimed asphalt pavement (RAP) and waste tire rubber, are now being used in pavement construction to conserve raw
Life Cycle Assessment of Rubber Modified Asphalt Pavement in . . . - Springer This paper presents a case study of rubberized asphalt pavement in Dickinson County, Michigan, employing a life cycle assessment (LCA) methodology The objective of this study is to demonstrate the environmental benefits of rubber incorporation in road construction by scrutinizing the material, transportation, manufacturing and construction
SSROC - Life Cycle Assessment and Potential Environmental Benefits of . . . The LCA analysed impacts related to the production of raw materials, including recycled materials like Reclaimed Asphalt Pavement (RAP) and recycled crushed glass, asphalt production processes, transportation, and paving operations during construction and maintenance phases
Life cycle assessment of asphalt pavements using crumb rubber: a . . . It can be preliminarily conclud-ed that using CR in the wearing course of SDA pavement is a potentially envi-ronmentally promising option to enhance pavement performance and make ma-terial use of waste tires in Switzerland Keywords: Life Cycle Assessment (LCA), Wearing Course, Semi Dense As-phalt (SDA) Pavement, Crumb Rubber, Dry Process
A comparative environmental impact analysis of asphalt mixtures . . . The objective of this work is to evaluate the potential environmental impacts of asphalt mixtures containing crumb rubber (CR) (vulcanised or devulcanised) and reclaimed asphalt pavement (RAP) assuming di erent Degree of binder Activation (DoA) of the aged binder by means of a life cycle ff assessment (LCA)
