Abstract

The invention discloses anti-aging asphalt for a muck truck road and a preparation method of the anti-aging asphalt, and relates to the technical field of asphalt. The foamed asphalt is firstly subjected to microwave heating treatment, and internal fine lines are expanded and communicated by utilizing magnetic nanoparticles to form a stable three-dimensional structure, so that the mechanical property of the asphalt is improved; after oxidation treatment, the foamed asphalt is modified by utilizing 1, 2, 3-tribromopropane, polyether glycol, dimethyl diphenyl diisocyanate and furanamide, so that the rut resistance of the asphalt is improved; then, the titanium dioxide nanosheets, 3-(4-bromophenyl)-2-propylene-1-alcohol, 2-(tert-butyl)-4-chloro-5-nitrophenol, 2-amino-4-chlorodiphenylamine, succinic anhydride, 2-chlorobenzoic acid vinyl ester and N-phenylbutylene diimide are used for preparing a self-made filler, and the anti-aging effect of the asphalt is improved. The asphalt prepared by the invention has anti-rutting and anti-aging effects.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to an anti-aging asphalt for road of muck trucks and a preparation method thereof. Background technique [0002] Asphalt pavement occupies a considerable proportion in highways due to its excellent performance. However, in recent years, due to the limitation of the performance of the asphalt pavement raw materials and the influence of external factors such as the increase of heavy-duty and overloaded vehicles such as muck trucks, the asphalt pavement is prone to rutting marks, and the rutting makes the road surface even worse and causes Other diseases, such as net cracks, potholes, potholes, etc., not only affect the comfort and safety of driving, but also reduce economic and social benefits. Therefore, the prevention and treatment of rutting diseases is the primary problem in today's highway construction. [0003] In addition, like most organic substances, asphalt will be subjecte...
