Особливості розповсюдження технологічних скріпних розчинів в пористій структурі щебеневої основи асфальтобетонного покриття при імпульсному ін`єкційному закріпленні

Abstract

The article is dedicated to the investigation of the peculiarities of spreading technological binding solutions within the porous structure of gravel base in asphalt concrete pavement through impulse injection fixation. The research utilizes a mathematical model based on Darcy`s, Navier-Stokes, and Shvedov-Bingham equations to analyze the process of solution penetration into the material pores under the influence of impulse hydrodynamic pressures. The study is conducted on samples of various gravel bases, applying impulse solution injection. The obtained results provide a better understanding of the solution penetration process into the material pores and canals and examine the influence of various factors such as intensity, magnitude, and amplitude of periodic impulse hydrodynamic pressures, properties of technological binding solution, and fractionation of the gravel material. They also serve as a basis for optimizing the technology of asphalt concrete pavement construction on fixed gravel base, which can enhance the quality and durability of the road structure. The obtained results and utilized mathematical models can be beneficial not only for the road construction industry but also for other fields that utilize porous materials with binding solutions, such as technologies for improving the load-bearing capacity of foundation soil bases, landslide mitigation, and other similar cases.
