Abstract

The invention discloses resin asphalt ultraviolet aging testing equipment and a testing method thereof and relates to resin asphalt aging testing equipment and a method which aim at solving the problem that an aging test can not be carried out on resin asphalt by adopting an xenon arc lamp or an open type carbon arc lamp. According to the resin asphalt ultraviolet aging testing equipment, a lamp bracket is arranged in an ultraviolet aging incubator, and four ultraviolet lamp tubes are horizontally fixed at the top of the lamp bracket and arranged in parallel through electric wires. The testing method comprises the steps of: 1, preparation of a test piece, namely a. preparation of a resin asphalt test piece; b. preparation of a resin asphalt concrete Marshall test piece; c. preparation of a resin asphalt concrete small beam test piece; 2, putting all aging groups into the ultraviolet aging incubator; putting room temperature groups into a room; 3, after 21 days, taking out all the aging groups; 4, a. carrying out infrared spectrum analysis on the resin asphalt test piece; b. testing the stability of the resin asphalt concrete Marshall test piece; c. carrying out a bending test on the resin asphalt concrete small beam test piece. The resin asphalt ultraviolet aging testing equipment and the testing method thereof are used for the resin asphalt aging tests.

Description

technical field [0001] The invention relates to a resin asphalt aging test method, in particular to a resin asphalt ultraviolet aging test method. Background technique [0002] At present, relevant specifications and standards for photoaging test methods are mainly formulated based on the International Organization for Standardization (ISO) light test methods for plastic materials. Domestically, there are GBT14522 (artificial weathering test methods for plastics, coatings, and rubber materials used in machinery industry products), GBT16422 (light source exposure test methods for plastic laboratories), etc., and the United States has ASTM G154-06 (Standard Practice for Operating Fluorescent Light Apparatus for UV Exposure of Nonmetallic Materials) and so on. The recommended light sources include xenon arc lamps, fluorescent ultraviolet lamps, open carbon arc lamps, etc. In China, high-pressure mercury lamps are also used for ultraviolet aging tests. Since the above-mentione...
