The specific gravity of the recycled aggregated taken was 2.76. The obtained value was between 2.5 to 3, therefore the aggregates can be used for pavement construction. CONCLUSION. …State highway agencies in Connecticut, Kansas, Minnesota, Wisconsin, and Wyoming have successfully designed and constructed rigid pavements containing recycled concrete aggregate (RCA). Success has been attributed in part to the minimization of old mortar content in the RCA during recycling processes, thereby controlling the total mortar content of the new portland …
