Strength Assessment and Mechanism Analysis of Cement Stabilized Reclaimed Lime-Fly Ash Macadam

An experimental study was conducted to investigate the strength and influence factors of cement stabilized reclaimed lime-fly ash macadam (abbreviation CSR), compared with cement stabilized macadam (CSM). The results indicate that, substitution rate of reclaimed lime-fly ash macadam (abbreviation RLFM) remarkably affects the strength. Nevertheless, the effects of substitution rate actually depend on the mortar content to a great extent. From the microscale point of view, the hydration products of CSR mixture appear in the morphology of whisker, plush and loose structures, which are not bonded with aggregates directly, resulting in the lower strength of CSR mixture. The present work will be useful for the waste managers and policy makers particularly in developing nations where proper guidelines are still lacking.
