neglected either. Life cycle assessment (LCA) as a method can be used to assess the environmental impacts of a road system over its entire life time. Studying the life cycle perspective of roads can help us improve the technology in order to achieve a system that has a lower impact on the environment. There are number of LCA tools available.

Considering Important Sustainability Factors with Concrete

A recent LCA study examined the impact of 12 different environmental factors on six different pavement structures. Environmental factors included greenhouse gases, energy, ecotoxicity, smog, odor, solid waste, and more. The analysis indicates the overall impact from the use-phase dwarfs impacts from all other phases of the pavement's life

PaLATE - Pavement Life-cycle Tool

PaLATE is an Excel-based tool for life-cycle assessment (LCA) of environmental and economic effects of pavements and roads. The tool takes user input for the design, initial construction, maintenance, equipment use, and costs for a roadway, and provides outputs for the life-cycle environmental effects and costs.

The objective of this study was to propose a methodology for assessing the environmental and economic life-cycle benefits when using recycled asphalt pavement (RAP) materials in highway projects. Previous studies on life cycle analysis (LCA) using RAP focused on the economics and/or environmental impacts during the material production process.

What PCR, EPD and LCA mean to AI | Asphalt magazine

All three elements, LCA, PCR and EPD, are needed to help understand the environmental sustainability of a given product throughout its life cycle. The PCR defines the rules of the game for the LCA, including boundary conditions, data used & system inputs. The LCA then assesses available data by the rules defined in the PCR to develop a model to

Looking to Aggregates to Improve Pavement Sustainability

For pavements, life-cycle cost analysis provides a way of measuring the economic consequences of choices in design, materials, construction techniques, construction windows, maintenance schemes, and end-of-life treatments over a prescribed analysis period. Life-cycle assessment (LCA) is a methodology used to evaluate a range of

Removing Shadows from Consequential LCA through a Time

Lack of dynamic accounting in consequential life cycle assessment (CLCA) can keep policy-makers from having an accurate analysis of emission flows over time. In this study, we propose a dynamic CLCA framework to assess the environmental consequences of pavements. Dynamic changes in the demand vector and technosphere matrices were computed using relevant time horizons of affected supply

Life cycle assessment framework for asphalt pavements

The construction, maintenance and disposal of asphalt pavements may lead to considerable environmental impacts, in terms of energy use and emissions during the life of the pavement. In order to enable quantification of the potential environmental impacts due to construction, maintenance and disposal of roads, an open life cycle assessment (LCA) framework for the asphalt pavements is presented
