Fatigue life evaluation of pavement embankments made with tire derived aggregates

Abstract

Rapid growth of populations and extension of societies leads to the production of waste by-products, which puts a burden on landfills. To address this issue, tire derived aggregates (TDA) from scrap tires have been used as road embankments in several projects. Three different test sections using different TDA, and TDA and soil mixtures, were constructed at the Integrated Road Research Facility test road in Edmonton, Alberta, Canada. Based on falling weight deflectometer tests in different months, the fatigue life performance of the TDA embankments was evaluated against that of a conventional control section using the measured horizontal strains at the bottom of the asphalt layer and the Asphalt Institute’s fatigue model. The results showed satisfactory performance of all three TDA test sections and significantly longer fatigue lives as opposed to the fatigue life of the control section. This analysis showed compelling evidence regarding the long-term performance of TDA material as road embankments in construction projects.

Development of a Mechanistic Method to Obtain Load Position Strain in Instrumented Pavement

“…Twelve asphalt strain gauges were installed to measure longitudinal and transverse strains at the bottom of the Hot Mixture Asphalt (HMA) layer in an instrumented Test Section located in McClain County, Oklahoma [4]. Asefzadeh, A. and Hashemian, L. developed empirical statistical pavement temperature prediction models based on two years of field strains collected from an instrumented test road located in Edmonton, Alberta, Canada [5]. Hossain, N. and Singh, D. conducted a study to better understand the cause of pavement failure under actual traffic loading and environmental conditions in an instrumented test section on I-35 in McClain County [6].…”

Shear Strength and Pull‐Out Response of Tire Shred‐Sand Mixture Reinforced with Deformed Steel Bars

“…e burning of tires releases highly toxic compounds such as dioxins and furans. ese pollutants disperse in air and travel a long distance and can remain for a very long time without decomposing [9][10][11]. Many countries prohibit the stockpiling of scrap tires and encourage their reuse and recycling [12].…”
