Abstract

The adoption of emerging sensing technologies to automate pavement management is crucial for developing Digital Twin solutions aimed at extending infrastructure lifespan, optimizing resource allocation, reducing rehabilitation costs, and ensuring road user safety. Incorporating carbon fibers can transform conventional asphalt mixtures into piezoresistive materials with self-sensing capabilities. However, the piezoresistive mechanisms and the capability to predict the viscoelastic behavior of carbon fibers asphalt mixtures remain uncertain. This study investigates the piezoresistive response of carbon fibers asphalt mixtures under dynamic loading conditions for self-sensing applications. Asphalt mixture specimens with varying carbon fibers contents were tested in the laboratory to assess the impact of carbon fibers content, loading frequency, and strain level on piezoresistive behavior. Results showed that the electrical response reflects the strain behavior of the mixtures, providing insight into both resilient and plastic strain components. This study contributes to advancing the development of materials with intrinsic sensing capabilities for monitoring asphalt pavement condition.

碳纤维沥青混合料的压阻机理

采用新兴传感技术实现路面管理自动化，对于开发旨在延长基础设施寿命、优化资源分配、降低修复成本和确保道路使用者安全的Digital Twin解决方案至关重要。加入碳纤维可以将传统的沥青混合物转变为具有自传感能力的压阻材料。然而，压阻机制和预测碳纤维沥青混合料粘弹性行为的能力仍然不确定。研究了碳纤维沥青混合料在动态加载条件下的压阻响应。在实验室中对不同碳纤维含量的沥青混合料试件进行了测试，以评估碳纤维含量、加载频率和应变水平对压阻性能的影响。结果表明，电响应反映了混合物的应变行为，提供了对弹性和塑性应变成分的深入了解。该研究有助于推动具有内在感知能力的材料的发展，以监测沥青路面状况。

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
