Abstract

Abstract

Asphalt pavement joints are prone to distresses such as cracking， faulting， and water infiltration. Existing studies mainly focus on material modification and construction techniques， while systematic design of joint components in asphalt layers remains limited. To improve the structural integrity and service performance of pavement joints， this paper proposes a novel joint component with a telescopic double-tube structure and establishes the corresponding construction technology system. First， based on the principle of load transfer and deformation coordination， a telescopic structure with square steel tubes was designed， and its load transfer efficiency under different parameter combinations was analyzed using the finite element method. Second， field monitoring was conducted on an in-service expressway to investigate the strain response of the component under coupled traffic loading and temperature effects. Finally， the construction process and key control measures were summarized. The results showed that the proposed component exhibited excellent load transfer capability and deformation adaptability， with a load transfer coefficient exceeding 0.88 and a low degree of dispersion. Field monitoring results verified its stable mechanical properties， and its strain response was highly consistent with temperature variations and traffic load distribution. The proposed construction method ensured installation accuracy and long-term durability.
