Abstract

This paper aims to evaluate the full-depth reclamation (FDR) technique for the improvement of urban streets in the city of Sirjan from a technical standpoint. Also, experimental results of soil-reclaimed asphalt pavement (RAP) blend stabilized with Portland cement has been represented. The experimental program of this research includes two phases. The first phase includes geotechnical investigation of different pavement layers for assessment of the quality of existing materials and estimation of a structural number of existing pavements, and the second phase includes determination of optimum mix design for the recycled layer (stabilized soil-RAP blend). To this end, unconfined compressive strength and density tests were conducted on several soil/RAP ratios of 100/0, 80/20, 60/40, and 40/60. For each blend, different percentages of Portland cement were mixed to soil/RAP blends and cured for 7 and 28 days. Results showed that by adding RAP to virgin soil, unconfined compression strength and optimum moisture content of stabilized samples decrease. Furthermore, the addition of Portland cement to the mixture increases compressive strength and decreases optimum moisture content. The results of this study also show the significant ability of FDR to increase the structural number of distressed pavements.
