Effect of compaction on the degradation of crushed concrete used as partial aggregate substitute in asphalt mixtures

The amount of crushed cement concrete continues to grow every day from the demolition of old structures, causing more pollution. Hence, owing to the increase in environmental awareness and stringent regulations governing the disposal, as set by environmental protection agencies, more effective measu...
