Pavement rehabilitation

 Proper maintenance will extend pavement life.

 However, best-maintained pavements will deteriorate with time and will need
rehabilitation.

 Conventional rehabilitation:
 Reconstruct with all new material

 Patch & overlay with new wearing surface

 Due to high construction cost, new methods of rehabilitation raised:
 Pavement Milling

 Pavement Recycling
