| Title of the article | Investigation of technical characteristics of paving bitumen combined with cellulose-containing stabilizing additives |
| Abstract. | The problems of the paving bitumen performance improvement by its modification with finely dispersed fillers are considered. The efficiency of the composite organic bindings’ application is shown in terms of bitusol (Trinidad asphalt). The stabilizing effect of the additives is shown by their ability to homogenize the hot asphalt concrete mixtures, i.e. to prevent segregation and stripping of the binding at high technological and working temperature. The additives’ properties are important for ensuring the required binding content and improving the quality of the mixture. We studied the technical characteristics of the composite organic bindings comprising the bitumen combined with the stabilizers based on the natural cellulose fibers including the well-known stabilizer Viatop-66 (Germany). The effect of the stabilizer and its components, as well as of the stabilizer content in bitumen on the binding performance is determined. The investigation shows the efficiency of using the stabilizers based on the cellulose fibers exposed to thorough delignification. The cellulose fibers in combination with gossypol resin most favourably affect the technical properties of the bitumen when the dosage is 4,5-6,5 % by the weight of the composition. Their estimation and the recommendations for their use in broken-stone/mastic asphalt concrete mixtures are given. |
