Abstract

Aims: This study aimed to investigate the challenges, methodologies, and innovations in the development of renewable asphalt pavements. It focused on evaluating the long-term performance, structural stability, and durability of renewable materials compared to conventional asphalt, while also identifying economic, regulatory, and technical barriers to their implementation. Methodology and results: A bibliometric systematic review was conducted using Scopus, following the PRISMA protocol. Co-occurrence and citation network analyses identified research trends and gaps. Findings reveal that reclaimed asphalt pavement (RAP) can reduce CO₂ emissions by 29.3%, while piezoelectric sensors in hot mix asphalt (HMA) can generate 76.56 MWh/month. Basalt fiber enhances hydrothermal resistance, and RAP in concrete improves shrinkage resistance with minor strength and density reductions. Conclusion, significance, and impact study: This research provides a comprehensive overview of renewable asphalt pavement, underscoring both its environmental benefits and current limitations. The insights provide valuable guidance for researchers, industry stakeholders, and policymakers in developing innovative and sustainable road infrastructure solutions. Future research should address the identified gaps to accelerate the adoption of renewable solutions in road construction.

Abstract

This study aims to determine the inter-floor shift due to earthquake spectrum response using nonlinear pushover analysis in a clinic building located in the Cimandiri Fault Zone as a basis for healthcare infrastructure management. This is very important because healthcare infrastructure is a place that must be available in any condition, even after an earthquake disaster. The Sukabumi area is an area located in the Cimandiri Fault Zone, so buildings in this area must be specifically designed to remain intact during disasters, especially earthquakes that often cause building damage. The research object that is the case study in this study is a 4-story clinic building that uses a reinforced concrete structure. The method used in the earthquake spectrum response analysis refers to SNI 1726:2019 and SNI 2847:2019, which have available spectral response webs, while the nonlinear pushover analysis uses the ATC-40 and FEMA-440 methods implemented in ETABS. The results of the analysis show that the inter-floor shift on the second and third floors exceeds the specified service limits, so it can be stated that the clinic building structure service in this case study requires damage control (DO). This can be seen based on the analysis results that the inter-floor shift of 201 mm in the X direction and 190 mm in the Y direction can cause moderate damage that can be repaired, so that health infrastructure service management is very necessary. Controlling recurrent damage due to earthquakes can be done with three retrofit scenarios consisting of the addition of shear walls, column coating, and steel reinforcement. The three scenarios are assessed and ranked based on the reduction of shifts, repair duration, and functional disruption. The addition of shear walls is the main recommendation without disrupting functionality, while column coating and the addition of steel reinforcement can disrupt health service operations. Retrofit scenarios can be recommended to support a sustainable health service infrastructure system in earthquake-prone areas. Earthquake spectrum response is a key factor that needs to be reviewed in building damage analysis as a basis for risk control management of health service infrastructure.

Abstract

Aim: This study aims to develop an adaptive management and maintenance model for flexible pavement in coastal areas by integrating road condition evaluation, cost analysis, and the effects of seawater immersion. The model is intended to improve maintenance efficiency, extend pavement service life, and support sustainable infrastructure management. Methodology and results: A quantitative and experimental approach was employed. Field surveys assessed pavement conditions using the Pavement Condition Index (PCI), Surface Distress Index (SDI), and International Roughness Index (IRI). Asphalt samples were tested in the laboratory under seawater immersion to evaluate strength reduction through Marshall and Indirect Tensile Strength tests. Damage data were integrated with maintenance cost analysis and traffic volume, producing a predictive model using regression and correlation analysis. Initial results indicate that seawater immersion significantly accelerates pavement deterioration and increases maintenance costs compared to normal conditions. Conclusion, significance, and impact study: he proposed model provides a comprehensive framework by considering technical, economic, and environmental factors specific to coastal infrastructure. Findings highlight the importance of condition-based maintenance strategies that are adaptive to climate change and extreme environmental risks. This study contributes to achieving sustainable infrastructure, resilient cities, and climate action for coastal environments.

Abstract

The degradation of reinforced concrete (RC) structures amidst the progression of corrosion within alkali-silica reaction (ASR)-affected structures is a complex phenomenon marked by diverse causal factors and repercussions. While the initiation phase of chloride-induced steel corrosion and ASR in RC structures has received extensive scrutiny, insufficient attention has been dedicated to comprehending the propagation phase (tp). Therefore, this study addresses this gap by centering its focus on the propagation phase, driven by the imperative need to formulate efficient and sustainable maintenance, repair, and management strategies for RC structures grappling with the concurrent impacts of degradation mechanisms such as ASR and corrosion. The use of corrosion initiation for predicting the operational lifespan of RC structures has been subject to rigorous examination by researchers and engineers, especially in light of recent breakthroughs in the concrete construction industry. In this context, the present investigation presents early findings, employing durability index tests to analyze the durability attributes of concrete incorporating both reactive and non-reactive materials (aggregates). Furthermore, the study proposes enhancements to prior research endeavors in this domain. While additional data is requisite to ascertain the cumulative influence of ASR and corrosion, conducting a comparative analysis of fluid transport rates through ASR-susceptible and ASR-non-susceptible concretes offers valuable insights into the maintenance and restoration of RC structures afflicted by both corrosion and ASR.
