What materials are used for road construction QuoraCHAPTER B RIGID PAVEMENT

Road consist of basically 4 layers 1 Sub grade The sub grade material should be clean and free from organic matter and should be able to be compacted by roller to form stable sub base The material should have the following characteristics B07 Rigid Pavement Repairs Using Asphalt Materials Asphalt plant mixed material may be used for many surface repairs to rigid pavement They will generally be used in cases of sunken slabs or extensive slab breakage Before making any asphalt repairs to rigid pavements the surface must be well cleaned and tacked with a paving asphalt or
