–The maintenance of pavements and particularly for flexible pavement is an essential requirement for the efficiency of highway network. For better serviceability, flexible pavements require more maintenance as compared to maintenance required for rigid pavements. But developing counties like India does not have sufficient budget or funds to satisfy the requirements. The maintenance & rehabilita...

This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

In last years, a new type of pavement has gained popularity, this is called Semi-Flexible Pavement (SFP). It consists porous asphalt with high air voids between (25-35) % filled cementitious grout materials. This substance offers substantial advantages over both common types pavements (concrete and flexible) such as good resistance to rutting durability. SFP considered an alternative exceed the...
