Abstract

The invention provides a device and a method for testing the adhesion performance of fibers and asphalt. The test device includes an asphalt pouring tank, a test mold bottom plate, clamping blocks, fiber caulking and fastening devices. The pitch pouring tank is an axisymmetric polygonal notch container member with a bottom plate and an open side wall, and is located at The clamp block at the end of the open side wall forms a closed groove, and the width of the open side wall end is narrowed, and is detachably placed on the bottom plate of the test mold. The slot and the groove at the intersection of the clamp block and the axis center line of the test device run through the entire test device, and bolts are respectively arranged on the beginning and end sides of the test device. The method is to quantitatively test the adhesion of the fiber itself to the asphalt by wrapping various fibers into fiber bundles with similar circular cross-sectional diameters, and calculating the mass change of the fiber bundles before and after stretching out the asphalt at the temperature of the asphalt softening point performance, making the test results more objective and comparable.

Description

technical field

[0001] The invention relates to a material test device and method, in particular to a fiber adhesion performance test device and method in asphalt mortar containing fiber materials, in particular to a fiber and asphalt material adhesion performance test device and method. Background technique

[0002] Fiber asphalt mixture is widely used in domestic and foreign projects. The mixture utilizes the reinforcing and toughening effect of the fiber material on the asphalt to enhance the high temperature stability and fatigue resistance of the asphalt mixture. Its anti-high temperature deformation and fatigue cracking performance are closely related to the performance of the fiber itself and the adhesion performance of asphalt. In order to research the fiber asphalt mixture with better performance, it is particularly important to test the fiber adhesion performance. However, there are many kinds of asphalt mixture fibers, and the bonding performance between differe...
