Abstract

The invention relates to the technical field of road building materials, particularly a reflective asphalt mixture. The reflective asphalt mixture is prepared from asphalt, an anti-stripping agent and mineral aggregate, wherein the anti-stripping agent accounts for 0.2-0.5 wt% of the asphalt, the asphalt-aggregate ratio of the asphalt to the mineral aggregate is 4-6%, and the mineral aggregate at least comprises ore powder, macadam and porous reflective glass microbeads. The mineral aggregate of the reflective asphalt mixture adopts the porous reflective glass microbeads, so that the adsorptivity of the glass microspheres for the asphalt is effectively enhanced, thereby relieving the problem of stripping of the reflective asphalt mixture. The reflective asphalt mixture has the advantages of higher pavement reflectivity, higher stability and higher safety for construction. Besides, the porous reflective glass microbeads are recovered from waste glass, thereby effectively reducing the influence of waste tempered glass on the ecological environment. Thus, the reflective asphalt mixture has great economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of road building materials, in particular to a reflective asphalt mixture. Background technique [0002] Since the reform and opening up, the speed of my country's highway construction has advanced by leaps and bounds. From 1988 to 2014, the mileage of my country's expressways has reached 111,950 kilometers. The rapid development of transportation will ease the tense situation of transportation. Asphalt pavements are also being built and expanded on an unprecedented scale. In addition, with the rapid development of the national economy and the improvement of people's living standards, the use of tempered glass is increasing. Tempered glass is a material with high strength and is difficult to degrade. Waste tempered glass has seriously affected the ecological environment. Under the circumstances of advocating green industry and sustainable development strategy at home and abroad, research on recycling and de...
