Abstract

The invention discloses equipment and a method for testing the bonding fatigue performance of a pavement crack filling material. The experiment equipment for testing the bonding fatigue performance comprises a testing device, a vibration platform and a base, wherein the vibration platform and the base are connected by four springs; the bottom surface of the vibration platform is provided with two motors; the motors are meshed with two eccentric shafts via gears; the two eccentric gears are respectively arranged in the horizontal and longitudinal directions; the bottom surface of the base is provided with a rubber layer so as to prevent the whole device from sliding in running; one of two test elements is fixed on the vibration platform, and the other one is fixed on a testing terminal the bottom of which is provided with universal wheels and which can move freely; two experiment test elements are bonded together via the pavement crack filling material, and vibrate in the longitudinal and horizontal directions; the bonding fatigue performance of the pavement crack filling material is evaluated comprehensively and quantitatively by utilizing the accumulative vibration time and the vibration level of the bonding interfacial failure and the interfacial failure level. The equipment and the method are used for testing the bonding fatigue performance of the pavement filling material.

Description

Technical field: [0001] The invention relates to a test device, in particular to a device and a method for testing the bonding fatigue performance of pavement joint filling materials. Background technique [0002] Cracks are one of the main diseases of asphalt pavement. The existence of cracks makes water on the road surface or other impurities enter the road base through the cracks, greatly reducing the overall strength and stability of the road, and causing more serious damage to the road. In the northern part of my country, the temperature changes rapidly, the temperature difference between day and night is large and the weather is cold, so the problem of cracks in asphalt pavement is particularly prominent. [0003] At present, the treatment methods for cracks at home and abroad are usually to repair the cracks with filling materials. Initially, hot base asphalt is used to fill the joints. However, because the performance of the base asphalt does not meet the requiremen...
