Asphalt Mixtures Modified with Tall Oil Pitches and Cellulose Fibres
Tall oil pitch and fiber modified asphaltic mixtures were characterized. Details of the materials tested are given. The tall oil pitches were crude distillation residues of crude tall oil. The cellulose fibers were of a commercial grade and consisted of selected sulphate cellulose and spruce fibers originating from recycled proper materials like from old newspapers. Tall oil pitches formed a very homogenous and stable mixture with bitumen. Soft fall oil pitches were added to bitumen in amounts of 15 to 20 percent of the weight of the hard bitumen. About 35 different testing methods were applied which can be classified as adhesion and composition tests for aggregate and fiber surfaces, bitumen quality tests, and tests for asphalt mixtures. Results of these tests are discussed. They give information on the adhesion and specification properties as well as the properties of asphaltic concretes: stability, resistance against water, wear of tall oil pitch modified asphaltic concretes, and wear of fiber modified asphaltic concretes.
