· Thus, similar to recycled crushed glass (RCG), recycled steel (RCS) is used in concrete pavement instead of using manufactured new steel to identify the variation in impacts. For example, using recycled steel at specific ratios – i.e. 20 % to 40 %, 60 %, 80 %, and 100 %-reduces the climate change impact from 4.24 % to 21.1 %, as shown in

Currently, three main approaches have been proposed for the major rehabilitation of semi-rigid asphalt pavement: direct paving, recycling, and reconstruction [5], [6]. These approaches can extend the service life of asphalt pavement to some extent, but they do not fundamentally alter the properties of the semi-rigid base material.
