The increasing axle loads from heavy traffic and rising temperatures due to climate change are placing immense stress on the asphalt base layers of roads, often preventing them from reaching their intended 30-year service lifespan.

摘要

The increasing axle loads from heavy traffic and rising temperatures due to climate change are placing immense stress on the asphalt base layers of roads, often preventing them from reaching their intended 30-year service lifespan. Current construction techniques and empirical design methods are proving insufficient, resulting in premature damage and costly repairs. This study explores the development of textile-reinforced asphalt base layers using a combination of experimental testing and simulation-based approaches, with the aim of improving the durability of asphalt pavements through the integration of high-strength tensile reinforcements. In contrast to conventional low-strength textile inserts, this research focuses on enhancing the mechanical resilience of the entire asphalt base layer. The approach targets crack prevention in the lower tensile zone by introducing advanced textile reinforcement structures made from profiled carbon rovings. These structures are specifically engineered for immediate absorption of high tensile forces via mechanical bonding and their superior tensile strength. The proposed reinforcement technologies have the potential to double the service life of asphalt pavements without increasing layer thickness, promoting more durable, sustainable infrastructure while significantly reducing maintenance costs. This paper will present key findings from experimental and simulation results, alongside novel production methods for the textile-reinforced asphalt base layers.
