Presented in this paper is a new study of the damaging effect of military armoured vehicles with rubber tires on flexible pavements. Two types of military armoured vehicles with rubber tires were studied, namely LAV-AT four-axle and LAV-300 triple-axle. A measure of the damaging effect of military armoured vehicles with rubber tires loads was achieved by correlating their equivalent loads with the AASHTO equivalency factors. The equivalent load was developed on the basis of mechanistic - empirical approach. It was found that the damaging effect of the studied military armoured vehicles with rubber tires loads is 0. 0.200 to 4.736 times the damaging effect of the standard 18 kips (80 kN) axle load depending on the thickness of asphalt layer. دراسة جديدة للتأثيرالتخريبي لأحمال العجلات المدرعة ذات الإطارات المطاطية رباعية و ثلاثية على التبليط الإسفلتي من خلال إيجاد معاملات آشتو المكافئة لها و لأول مرة و بستخدام طريقة الحل الميكانيكي-التجريبي. لقد وجد أن تأثير الأحمال التخريبي لأحمال العجلات المدرعة ذات الإطارات المطاطية التي تمت دراستها يتراوح مكن 0.200 إلى 4.736 مرة تأثير حمل آشتو القياسي حسب سمك طبقة الإسفلت.
