Mechanical Concrete for Enhancing the Properties of Pavement Base/Subbase
Pavements are subjected to many forms of stress during their service life including cracking and failures. Many of the failures can be attributed to poor subgrade, freeze-thaw cycle variations, and fatigue under repetitive axle loadings. Fatigue related cracking can lead to riveting, pot holes, and cracks in the wheel path, etc. One way to improve pavement performance is to enhance the mechanical properties of the base/subbase. This article describes the research on mechanical concrete comprising of waste tire-derived geo-cylinders filled with coarse aggregates to improve mechanical properties. Mechanical concrete helps in creating a more stable platform for the pavement system through confinement effects and distributes the stresses from axle loads to the ground and increases the subbase moduli. Some of the benefits of using mechanical concrete are cost effectiveness, savings in material and labor, and sustainability. This paper focuses on the presentation and discussion of laboratory test results conducted on representative pavement sections consisting of mechanical concrete with different tire diameters and its effectiveness in enhancing the pavement subgrade moduli under both static and fatigue loads up to 1 million cycles.
