The aim is to determine critical stress conditions for foam glass aggregate insulation in flexible pavements to ensure structural integrity.
Laboratory cyclic triaxial tests conducted to evaluate mechanical properties of foam glass aggregate.
Full-scale accelerated pavement testing performed with a heavy vehicle simulator.
Analysis of resilient modulus and permanent deformation behavior of foam glass aggregate.
FGA exhibits stress-dependent elastoplastic behavior with resilient modulus values between 70 and 200 MPa.
Samples commonly demonstrated plastic creep or incremental collapse under stress.
Critical deviatoric stress thresholds identified as 15–25 kPa for stable deformation behavior.
