“…By contrast, in this case study with low to medium traffic, traffic growth and the emission factors/fuel economy changes do not have a large impact on the results, because they tend to offset each other. Butt et al (2015) discuss the use of attributional and consequential LCA studies for road pavements, where environmental impacts are attributed to products or actions, or the consequences or relative changes of making different decisions are estimated, respectively. These types of study can be used to estimate impacts in standalone studies of a single material or process, or in comparative studies of different choices.…”

“…to estimate the environmental impacts of a paving material) but is a problem for comparative LCA studies where different use phase outcomes could result (e.g. where different materials or maintenance programmes will lead to different surface condition) (Butt et al 2015). The use phase represents the longest phase in the life cycle of a pavement, remaining in service for decades (much longer than the construction phase), so it can have a significant environmental impact.…”

“…Research has shown that this approach can be easily adopted for materials such as concrete [23,24]. Another merit of this method is its utility in evaluation of building [25][26][27][28][29][30] and road construction [31] applications. In view of these merits, this study uses LCA for evaluation of energy consumption, CO 2 emission, and the costs associated with aggregate production and recycling.…”

“…It also involves taking into account the appropriate geographical and temporal scope such as the location and the period of the assessment. Different types of decisions are outlined based on at what level of complexity (network or specific project) and at what stage within the planning process (early planning or late planning/design) the decision is to be made (Butt et al 2015). Such decisions influence system boundaries selection by using attributional or consequential LCA.…”
