The tests are performed on compacted bituminous material under a sinusoidal loading or other controlled loading, using different types of specimens and supports. The procedure is used: a) to rank bituminous mixtures on the basis of resistance to fatigue; b) as a guide to relative performance in the pavement; c) to obtain data for estimating the structural behavior of the road; and d) to judge test data according to specifications for bituminous mixtures.\nBecause this European Standard does not impose a particular type of testing device, the precise choice of the test conditions depends on the possibilities and the working range of the device used. For the choice of specific test conditions, the requirements of the product standards for bituminous mixtures need to be respected.\n\nResults obtained from different test methods or using different failure criteria are not assured to be comparable.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-50178eb e-grid e-con-full e-con e-child\" data-id=\"50178eb\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1b1f24f elementor-widget elementor-widget-text-editor\" data-id=\"1b1f24f\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>4PB Testing Setup<\/h2><ul><li>50 KN EHF-U Servopulser system<\/li><li>4PB testing tool (Figure 2)<\/li><li>QF-40 Hydraulic power supply<\/li><li>4830 Controller<\/li><li>Windows software for 4830 controller<\/li><li>4PB Fatigue calculation files<\/li><li>\u00a0<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-24916f1 elementor-widget elementor-widget-image\" data-id=\"24916f1\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/shimadzu-testing.com\/wp-content\/uploads\/2024\/09\/asphalt-testing-package-fatigue-test-according-to-en-12697-24-2004-annex-d-4pb-pr-fig2-assembly-for-4pb-stiffnes-test.jpg\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"asphalt-testing-package-fatigue-test-according-to-en-12697-24-2004-annex-d-4pb-pr-fig2-assembly-for-4pb-stiffnes-test\" data-elementor-lightbox-description=\"Figure 2: Assembly for 4PB Fatigue and Stiffness test\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MTY1NTIsInVybCI6Imh0dHBzOlwvXC9zaGltYWR6dS10ZXN0aW5nLmNvbVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyNFwvMDlcL2FzcGhhbHQtdGVzdGluZy1wYWNrYWdlLWZhdGlndWUtdGVzdC1hY2NvcmRpbmctdG8tZW4tMTI2OTctMjQtMjAwNC1hbm5leC1kLTRwYi1wci1maWcyLWFzc2VtYmx5LWZvci00cGItc3RpZmZuZXMtdGVzdC5qcGcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"768\" height=\"578\" src=\"https:\/\/shimadzu-testing.com\/wp-content\/uploads\/2024\/09\/asphalt-testing-package-fatigue-test-according-to-en-12697-24-2004-annex-d-4pb-pr-fig2-assembly-for-4pb-stiffnes-test-768x578.jpg\" class=\"attachment-medium_large size-medium_large wp-image-16552\" alt=\"Figure 2: Assembly for 4PB Fatigue and Stiffness test\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Figure 2: Assembly for 4PB Fatigue and Stiffness test<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-70e6915 elementor-widget elementor-widget-text-editor\" data-id=\"70e6915\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><strong>Testing method<\/strong><\/h2><p>According to named standard this test is applied after the stiffness test (Stiffness test is a subject of No. SCA_300_065)<\/p><p>\u00a0<\/p><ol><li>based on principle of 4-point bending test,<\/li><li>test sample: beams of 450 mm length, 50 mm x 50 mm or 70 mm x 70 mm,<\/li><li>LVDT controlled deflection sine wave, maximum bending strain should be chosen in three different levels, so that fatigue lives are between 1E4 and 2E6 cycles.
