Special Issue Information

Dear Colleagues,

With the emergence of extreme climate events and the increasing traffic load in recent years, the performance requirements for pavement materials are increasing. Sustainable pavement materials have attracted much attention from both the research community and industry. Building and preserving efficient, reliable, and sustainable pavement is crucial for economic and social development. The design of pavement materials and structures significantly influences road durability. The main components of pavement materials are bitumen, cement, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, and geo-composites. Road performance can be affected by vehicle loading and environmental conditions, including light, temperature, oxygen, moisture, etc. New and innovative materials and mix designs considering both durability and low carbon emissions are also crucial. An accurate assessment of pavement performance, including stress and strain state, carbon emissions, and environmental effects, has become increasingly important.

This Special Issue encourages submissions of recent work that further our understanding of the mechanisms influencing the durability and low carbon emissions of pavement materials. This Special Issue also lays out an interdisciplinary framework that not only aims to advance specific areas of science and engineering but also to help advance the state of practice in road engineering. Review articles that describe the current state-of-the-art are also encouraged. Topics welcome for submission to this Special Issue include, but are not limited to:

(1) Mechanism studies of pavement materials' performance, including aging, recycling, and fatigue;

(2) Development and evaluation of innovative materials or technologies in road engineering;

(3) Performance evaluation of sustainable pavement materials and structures;

(4) Life cycle assesment of transportation infrastructure mateirals

(5) Low-carbon construction and maintenance technology of pavement materials.

Road infrastructure serves as a foundational driver of a nation’s economic and cultural growth. Incorporating life cycle cost analysis (LCCA), as well as considerations of availability and environmental impact, enables policymakers to make strategic decisions that not only enhance fiscal efficiency but also support sustainable progress. This paper centers on an in-depth examination of two prevalent pavement technologies: continuously reinforced concrete pavements (CRCP) and jointed plain concrete pavements (JPCP). It specifically delineates the application of these methods to a hypothetical one-kilometer motorway construction in Germany. Employing LCCA for concrete pavements, the paper evaluates long-term fiscal prudence among alternative investment opportunities, factoring in resource utilization—both materials and machinery—and long-term care and upkeep obligations over the pavements’ operational lifespans. The analysis extends to appraise agency expenditures associated with the pair of pavement strategies and estimates the concomitant delay durations and costs relevant to the exemplar project. Central to this research is the investigation of road availability and its quantifiable influence on traffic efficacy, parsing through metrics such as the tally of days roads are out of service and the subsequent repercussions on vehicular flow. The investigation also proposes strategies for the reduction of embodied carbon in CRCP and JPCP systems. While accounting for variances in functional performance and vehicular comfort levels, this study contributes scientifically by tackling pragmatic engineering dilemmas involved in pavement selection, with a spotlight on minimizing costs, curtailing traffic interruptions, and mitigating ecological impacts for the duration of the pavement’s life cycle.

In the quest for more sustainable pavement solutions, this study demonstrates the successful strengthening of a unique noise-reducing two-layer road surface. While existing noise-reducing pavements reveal high acoustic efficiency, they lack mechanical strength, and earlier research efforts addressed the optimization of the individual components of this system, and a comprehensive perspective on its integrated performance remained elusive. Therefore, this research bridges this knowledge gap through an in-depth laboratory evaluation, in which the requirements for the realization of a full-scale demonstrator were defined, followed by a comprehensive performance assessment in terms of acoustic and mechanical strength. The post-construction assessment reveals the system’s multifaceted strengths, considering noise reduction, resilience under heavy traffic, pavement deflections, and skid resistance, assessed by CPX measurements, accelerated pavement tests using the MLS 30, skid resistance tests employing the pendulum test, as well as the slow-moving longitudinal friction test (MicroGriptester) and falling weight deflectometer (FWD) measurements. Although the optimized system implies lower noise-reduction potential, it exhibits great strength compared to previous noise-reducing pavements. In general, the system offers viable noise mitigation solutions for urban highways, particularly in settings where traditional noise abatement measures are constrained by space. The insights from this study serve as a valuable reference for the development and evaluation of innovative road engineering materials and technologies. Full article
