Physical properties of cathode ray tube (CRT) used as aggregate for road pavement application

The amount of electronic waste (e-waste) generated globally has been increasing steadily, including in Malaysia. Utilizing the e-waste as alternative recycled materials can help to conserve natural resources as well as reduce the demand for natural resources. Furthermore, recycled materials can...
