Abstract

This paper conducts maintenance scheme design and material performance research based on the S218 Provincial Road intersection treatment project. On the one hand, it accurately identifies the causes of pavement diseases by carrying out special inspection work such as on-site core drilling and sampling, pavement pit exploration tests, pavement structure strength detection, ground radar detection, and drainage facility investigation. On the other hand, taking the AC-13 gradation as an example, the mix proportion design and road performance research of three modified asphalt mixtures were carried out. The polymer resin modifier (AR-3) modifier can increase the optimal oil-to-stone ratio of asphalt mixtures, endowing them with excellent low-temperature crack resistance. The Marshall stability has increased by approximately 25%, demonstrating excellent high-temperature stability. Under high-temperature and heavy-load conditions (dynamic stability at 70℃ and 1.0Mpa), the anti-rutting capacity can reach 2.5 times the technical standard. Both the indoor test research and the on-site engineering detection results show that the polymer resin modifier (AR-3) has better comprehensive road performance and can effectively delay the development of pavement diseases when applied to intersection sections.
