Performance of high content reclaimed asphalt pavement (Rap) in asphaltic mix with crumb rubber modifier and waste engine oil as rejuvenator

The utilisation of reclaimed asphalt pavement (RAP) as a suitable substitute for natural aggregate and binder offers an energy-saving and cost-effective approach to enhance the performance of asphalt mix. Realising the potential use of RAP as a promising recycling technique, many countries are seeki...
