However, the impact of repeated micro crack healing cycles on deformation has not been investigated thoroughly. An attempt has been taken in this work to investigate the crack healing cycle&rsquo;s phenomena on specimens of 100 mm diameter and 63 mm height, prepared using Marshall Method. Specimens were divided into two sets. The first set was subjected to repeated indirect tensile stresses, while the second set was subjected to the repeated double punch shear stresses (both at 25 &deg;C) to initiate micro cracks within the specimens using controlled stress mode of loading. After controlled number of stress application, Specimens were subjected to external heating in an oven at 60&deg; C and allowed to heal for two hours, conditioned, then subjected to another two courses of repeated stresses and healing. The permanent deformation of the specimens was monitored through continuous video capture in the pneumatic repeated load system (PRLS). The impact of asphalt content, type of test, and healing cycles on the permanent deformation have been analysed. <\/span><\/p>\n<p style=\"text-align: left;\"><strong><span style=\"font-family: 'Times New Roman', serif;\">&nbsp;<\/span><\/strong><\/p>\n<p style=\"text-align: left;\"><strong><span style=\"font-family: 'Times New Roman', serif;\"><br \/> <\/br> <\/span><\/strong><img decoding=\"async\" alt=\"\" src=\"https:\/\/coeng.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/3\/uploads\/1\/saad sarsam\/saad.png\"><\/img><span style=\"font-family: 'Times New Roman', serif;\"><\/span><\/p>\n<p style=\"text-align: left;\"><span>&nbsp;<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u0627\u0644\u062a\u062f\u0631\u064a\u0633\u064a \u0641\u064a \u0642\u0633\u0645 \u0627\u0644\u0647\u0646\u062f\u0633\u0629 \u0627\u0644\u0645\u062f\u0646\u064a\u0629  \u0627\u0644\u0627\u0633\u062a\u0627\u0630 \u0633\u0639\u062f \u0639\u064a\u0633\u0649 \u0633\u0631\u0633\u0645 \u064a\u0634\u0627\u0631\u0643 \u0641\u064a \u0627\u0644\u0645\u0624\u062a\u0645\u0631 \u0627\u0644\u0639\u0627\u0644\u0645\u064a \u0644\u0644\u0631\u0635\u0641 \u0627\u0644\u0627\u0633\u0641\u0644\u062a\u064a &#8230; <a class=\"cz_readmore\" href=\"https:\/\/coeng.uobaghdad.edu.iq\/?p=2440\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":6,"featured_media":17245,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[5],"tags":[],"class_list":["post-2440","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-5"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
