Summary: This study investigates the Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) for climate change adaptation strategies in various locations in Canada. The study shows that these adaptation strategies, although initially increasing costs and emissions, are offset over the life of the pavements. Different locations require different adaptation strategies, but overall, climate change adaptation strategies are beneficial for all locations.

Summary: This study compares the environmental performance of sixteen Cement Treated Base (CTB) mixtures with different cement percentages, production methods, and recycling procedures. The results show that higher cement percentages allow for thinner base-course layers, offsetting the increased environmental burdens from cement production and transport. Additionally, on-site production significantly reduces environmental impacts compared to central-plant-mixed production.

Summary: The use of concrete pavement on Korean expressways is increasing, leading to higher maintenance costs. A study on the life-cycle cost of asphalt and concrete overlays was conducted to extend the service life of concrete pavements. The research showed that concrete overlay had higher economic efficiency than asphalt overlay over a 20-year cycle.

Summary: Lean asphalt is a hot mixture with lower binder content, allowing for high RAP content and increased pavement structural capacity. However, concerns arise regarding its performance due to low binder content and high air void content. The study suggests that 40% RAP content is necessary to meet moisture susceptibility requirements. Fatigue testing shows satisfactory resistance, but semicircular bending and IDEAL-CT testing reveal low cracking tolerance. Life cycle assessment shows that lean asphalt with 40% RAP has lower environmental impact, and life cycle cost analysis confirms its lower economic impact compared to other base materials.

Summary: This study compares the life cycle impacts of several pavement solution alternatives and finds that cold recycled mixtures in the base layer perform the best, while combining cold base layer with hot recycled mixtures in the binder layer maximizes the service life of the pavement solution.

Summary: This paper provides a methodological review of published studies on asphalt pavement Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) and recommends incorporating both approaches, defining standard functional units (FUs), considering complete life cycle, and emphasizing probabilistic analysis of uncertainty.

Summary: This study aims to quantify the life-cycle carbon footprint of asphalt pavement under warming temperatures due to climate change. It found that increasing temperatures lead to faster structural deterioration of pavement, requiring earlier or more frequent overlay treatments, which in turn increase CO2 emissions in material and construction stages but reduce emissions during pavement use. Climate change causes greater CO2 emissions over time during the study period.

Summary: This study aims to reduce energy consumption and emissions in the whole life cycle of SFP based on ensuring its good pavement performance through applying fly ash, rubber particles, warm mixing technology, and recycled asphalt pavement (RAP) in SFP. It is observed that by replacing cement with fly ash and rubber particles, the energy consumption and emission of SFP are significantly reduced. However, the use of high content RAP instead increases the energy consumption and emissions of SFP.

Summary: This study evaluated the performance of recycled asphalt pavement (RAP) as a substitute for natural aggregate in the maintenance of asphalt concrete for flexible pavements. The research also compared the mechanistic performance of warm mix and cold mix asphalt concretes using RAP. The results showed that RAP-AC60/70 and RAP-CMS-2 h mixtures had comparable performance to the conventional limestone-AC60/70 mixture, with lower material cost.

Summary: In this study, it was found that using 20% RAP in the region could result in a 14% reduction in total life cycle costs compared to conventional materials, with a 57% cost reduction observed for a RAP manufacturing plant. No significant cost differences were observed between RAP and traditional materials in terms of labor, material transportation, and construction activities.

Summary: This article presents a method for assessing the condition of in-service asphalt pavement using the Random Forests algorithm and Gini importance measurement to extract key detection indicators. A cost-effective approach is proposed by reducing data dimensions. The results demonstrate that the proposed method achieves consistent assessment results with the traditional method, while reducing the burden of data collection.

Summary: With the impact of climate change, it is necessary to reduce greenhouse gas emissions in road construction. Previous studies have analyzed parameters of asphalt production and suggested potential improvements in GHG reduction. However, relying on data from single sources can lead to unreliable assumptions. This study conducts separate assessments and uses multiple sources to calculate GHG emissions, enabling systematic comparison and eliminating uncertainties. The results highlight the importance of substituting recycled materials for virgin materials and the influence of material moisture on GHG emissions. Furthermore, the study compares traffic-related GHG emissions in road sections with different traffic volumes and emphasizes the role of the construction industry in seeking climate protection.

Summary: This paper presents a comprehensive eco-efficiency assessment for six promising long-life asphalt pavement (LLAP) designs, finding that under the baseline design scenario, the inverted, enhanced semi-rigid base, and composite asphalt pavement perform best in terms of greenhouse gas emissions, total embodied energy, and life-cycle cost. In most cases, the enhanced semi-rigid base and inverted designs are the most eco-efficient solutions, although the composite pavement may surpass the enhanced semi-rigid base for longer design life. The raw material phase is identified as the most critical source of environmental impacts across all life-cycle activities.

Summary: This research conducts a comparative Life Cycle Assessment (LCA) to evaluate the environmental potential of using multi recycled materials in asphalt pavement construction. The results show that utilizing reclaimed asphalt pavement (RAP) and new eco-friendly products can reduce environmental impacts. Shifting the fuel of the asphalt mix plant from heavy fuel oil (HFO) to natural gas, as well as adopting a lower energy and solvent consumption extraction method, also contributes to reducing environmental impacts.
