“…However, the asphalt mix with 45% of RCA demonstrated a decline in environmental performance across all impact categories when compared to ordinary asphalt mixes. [20] focuses on evaluating the environmental and economic sustainability of Perpetual Pavements (PPs) in comparison to Conventional Flexible Pavements (CFPs) and Conventional Rigid Pavements (CRPs) for road construction, with a specific case study in Barranquilla, Colombia. Using LCA and Life Cycle Cost Analysis (LCCA) methodologies, it finds that PPs exhibit lower environmental impacts and higher cost-efficiency than CFPs and CRPs, especially in terms of contamination potential.…”

The pursuit of sustainable pavement construction necessitates careful consideration of selecting appropriate materials due to their significant impact on road investments. Therefore, this study aims to analyze and assess the environmental effects of four distinct pavement materials including A main road, Plain concrete (PC), and three equivalent alternative roads: reinforced concrete (RC), fibrous concrete (FRC), and Hot Mix Asphalt (HMA). The study assesses various pavement alternatives by considering their cumulative energy demand and damages across different categories. The life Cycle Assessment (LCA) tool is used by implementing LCIA ReCiPe 2016 Endpoint (H) V1.07 / World (2010) H/A methodology and Simapro software. A case study of the Cairo-Suez Desert Road in Egypt is selected to apply the study to it. The damages are measured in two categories: human health and ecosystem quality. The results indicate that RC pavement has the highest damage effect in both categories, with values of 94.20 and 36.99 respectively. Both PC and FRC pavements exhibit damage but to a lesser extent. HMA shows a relatively lower damage effect in both categories. These findings can enhance the comprehension of environmental implications associated with various pavement materials, offering valuable insights to decision-makers in the process of selecting sustainable pavement options.

“…The LCCA (also called life cycle costing) is one of the most robust methodologies available to estimate the associated costs of products, processes, activities, or projects throughout an entire or partial life cycle [7,9,77]. For this study, the LCCA was executed according to the ISO 15686-5 standard [78].…”

“…Among these infrastructures, pavements are particularly necessary because they guarantee the interconnection of urban and rural areas with the production and distribution centers [4][5][6]. Nonetheless, the road infrastructure industry has two major problems: (i) higher environmental impacts and (ii) elevated production costs [7][8][9]. The preceding has motivated a growing interest in the state-of-the-art for developing novel sustainable materials [8,[10][11][12].…”

Continuous research efforts have been developed in the literature to raise the sustainability components of the road infrastructure industry, i.e., reduce potential contaminants and augment financial profitability. In this regard, this investigation aims to explore the feasibility of producing Hot Mix Asphalt (HMA) with the inclusion of Recycled Concrete Aggregate (RCA) as a partial substitute for coarse Natural Aggregates (NAs). Thus, four different HMAs were considered, namely HMAs with coarse RCA contents of 0, 15, 30, and 45%. Specifically, the mechanical and sustainability properties of the asphalt mixtures were determined. On the one hand, the Marshall design parameters, resilient modulus, moisture susceptibility, rutting resistance, and fatigue life were addressed as mechanical properties. Meanwhile, regarding the sustainability properties, the environmental impacts and production costs were estimated using the Life Cycle Assessment (LCA) and the Life Cycle Cost Analysis (LCCA) methodologies, respectively. Consequently, the following conclusions were obtained: (i) as the coarse RCA content increases, the mechanical behavior of the HMA progressively deteriorates; (ii) this decrease in mechanical performance is acceptable up to a 15% RCA of coarse RCA, whereas for higher dosages this alteration is abrupt; and (iii) the RCA only generates sustainability benefits at a 15% replacement amount.

Rigid pavements are often used on clay soils with long-term settlement history and are subject to damage from traffic loads. It must be analyzed for deflections in rigid pavements built on clay to prevent damage and extend pavement life. If deflection exceeds the permit, the pavement will experience damage. One way to minimize these problems is by installing vertical drains to improve the soil. Installing a vertical drain on the soil can increase the modulus of the subgrade reaction represented as soil- bearing capacity and minimize the potential for pavement deformation. This research aims to analyze the deflection of rigid pavement on clay soil with vertical drains. The finite element method is utilized to analyze the deflection. The pavement is modeled as a 10 m long and 7 m wide slab with thickness variations ranging from 150 mm to 350 mm. Static loads are used to model vehicle loads with load positions at the pavement’s center, ends, and edges. For all slab thicknesses subjected to varying center, end, and edge loads, the maximum deflection of rigid pavement over vertical drain soils is lower than that of soils without vertical drains. It can be concluded that rigid pavement deflection can be reduced using vertical drains for soil improvement.
