ASPHALTIC CONCRETE MADE WITH ORDINARY PORTLAND CEMENT COATED AGGREGATE

This paper presents the results of a laboratory investigation into the effectiveness of using aggregates coated with ordinary portland cement for use in the production of bituminous mixtures. Cement coating techniques give as a result aggregate particles coated with a hydrated Portland cement layer, this increases the surface roughness of the aggregate particles and improves adhesion between aggregate and bitumen. The cement coated aggregates are used in bituminous mixtures following the usual mix procedures. Evaluation of the performance of cement coated aggregate-bituminous mixes is made by measuring stability, creep stiffness, permanent deformation and moisture damage resistance. The results indicate that this technique improves the properties of a bituminous mix by increasing the values of engineering parameters and by reducing the susceptibility of the mix to moisture damage.
