A procedure is designed for the preparation of a photocatalytic bituminous road surface consisting of a stage involving the preparation of a bituminous base ( 2 ) with a thickness coming between 10 mm and 60 mm and containing gaps ( 5 ), and a subsequent stage for spreading a cement mortar ( 7 ) over said bituminous base ( 2 ), containing: a photocatalytic material for achieving a photocatalytic reaction, a plasticizing admixture suitable for fluidifying said mortar ( 7 ), and amorphous silicon dioxide suitable for making said mortar ( 7 ) more compact, said cement mortar ( 7 ) thus being suitable for coating the gaps ( 5 ) in said bituminous base ( 2 ).
