摘要：A good road network is a key for rapid growth of economy of a country. It provides connectivity toremote areas for various transport activities. There is about 4.2 millions kilometre road network in India, which rankssecond in the world only after United States. Most of the roads are bituminous surfaced pavements. These roads areperiodically resurfaced as maintenance action. It is due to this periodic maintenance the roads have attained a higherraised level as compared to adjoining properties in urban locality. These roads can be lowered down up to required andfeasible depth by milling process and can be resurfaced with suitable layer of bituminous mixes replacing all or part ofthe bituminous pavement. Reclaimed asphalt pavement (RAP) materials are resulted from milling process. In this studysamples of Reclaimed asphalt pavement (RAP) materials were collected and analysed for suitability of their usage inflexible pavements. Their characteristics including gradation, California Bearing Ratio(C.B.R).Aggregate Impact value,Aggregate Crushing value, Specific gravity, Flakiness & Elongation Index, Loss Angles Abrasion value, Waterabsorption and soundness were determined and compared to the MORTH specifications. Form the study it was foundthat the RAP materials can be effectively used in the soil sub-grade, sub-base and base of the flexible pavementsresulting in reduction of the construction cost.
