Flexible Pavement Maintenance SOUTHERN NMM

Pavement maintenance is very important to prolong pavement life as well as to preserve the road functional in order to provide safe, comfortable riding and reliable passage to all traffics. Generally, neglecting or delaying the road maintenance activities may increase the overall cost of repair and also affect the vehicle operating cost for the road user.

Pavement Maintenance – Prevention or Repair? –

Pavement maintenance is normally distinguished from pavement rehabilitation, because maintenance treatments do not significantly change the structural or load-carrying capacity of the pavement. Preventive maintenance is one of the biggest components of a pavement preservation program, while other types of maintenance may not be considered preservation.
