The product-A2 is: a product of molecular weight of 45-20000 g/mol obtained by reacting (di)alk(en)ylphenol and 1-10, preferably 1-5 carbon aldehyde, followed by (poly)oxyethylation and/or (poly)oxypropylation of 1-50, preferably 2-20 carbon alk(en)yl group; partly (poly)ethoxylated and/or (poly)oxypropoxylated 2,2-bis(4-hydroxyphenyl)propane-epichlorohydrine of molecular weight of 45-20000 g/mol; partly (poly)ethoxylated and/or (poly)oxypropoxylated bis-(4-hydroxyphenyl)-ethane epichlorohydrine copolymer of molecular weight of 45-20000 g/mol; partly (poly)ethoxylated and/or (poly)oxypropoxylated bis-(4-hydroxyphenyl)-methane epichlorohydrine copolymer of molecular weight of 45-20000 g/mol; (poly)ethoxylated and/or (poly)oxypropoxylated 1-20, preferably 1-10 carbon alkyldicarboxylic acids of molecular weight of 100-20000 g/mol; partly (poly)ethoxylated and/or (poly)oxypropoxylated 10-30 carbon fatty acids of molecular weight of 100-20000 g/mol, preferably fatty acid of tall oil; 6-30 carbon alk(en)yl(aryl) sulfonic acid salt or 6-30 carbon alk(en)yl(aryl)amine salt, preferably dodecylbenzenesulfonic acid salt, amino tallow or cyclohexylamine; and/or a salt of 6-30 carbon alk(en)yl(aryl) sulfonic acid, morpholine, pyrazine, pyrazolin, pyrazolone, pyridine, pyridone, pyrimidine, pyrrole, pyrrolidine, pyyrolidone, pyrroline, toluidine, imidazole, indole, indoline or oxindole, preferably dodecylbenzenesulfonic acid salt or morpholine salt. The product-A has 3-50 phenol units. Independent claims are included for: (1) a process of preparing the bituminous product comprising contacting the additive with the bituminous product at 100-250[deg]C; (2) a process of preparing coating comprising mixing the bituminous product with granule where the temperatures of granular fractions is different, and forming a coating at 60-200[deg]C, preferably 100-200[deg]C; (3) an aqueous bituminous emulsion comprising bituminous products and a cationic emulsifier; and (4) a process of preparing a bituminous emulsion comprising contacting the bituminous product with the additives at 100-200[deg]C, preferably 120-180[deg]C before the emulsification of the mixture.
