Problems solved by technology

Due to the small construction depth of the dense suspension structure mixture and the small anti-friction coefficient, there is a risk of the aircraft rushing out of the runway under extreme conditions
At the same time, since the curing of epoxy asphalt is a gradual process, and the repair and paving time of the airport pavement is short, the newly repaired airport pavement will be open to traffic in a short period of time, and there are problems of insufficient early strength and anti-rutting performance , these are problems that cannot be solved by densely graded epoxy asphalt mixture

Abstract

The invention discloses an epoxy asphalt mastic macadam mixture suitable for an airfield pavement and a preparation method thereof. The mixture is prepared from the following raw materials in parts bymass: 0.7 to 2.1 parts of epoxy resin, 0.5 to 1.9 parts of curing component, 2.9 to 7.9 parts of SBS modified asphalt, 100 to 150 parts of mineral aggregate and 0.3 to 0.6 part of fiber. The preparation method comprises the following steps: preheating SBS modified asphalt, adding the preheated SBS modified asphalt into preheated coarse aggregate and fine aggregate determined according to design gradation, adding uniformly mixed epoxy resin and curing component, stirring, finally adding fibers and mineral powder, and stirring. By utilizing the characteristics of high strength, excellent waterdamage resistance, excellent aging resistance and the like of the epoxy asphalt, the prepared epoxy asphalt mastic macadam mixture suitable for the airfield pavement has good strength and durability so that the airfield pavement has good wear resistance, and the risk of wheel track diseases of the asphalt pavement is reduced. The preparation method is simple, energy-saving and environment-friendly, and has relatively high social value and economic value.

Description

technical field [0001] The invention belongs to the technical field of road building materials, and relates to an epoxy asphalt mastic macadam mixture suitable for airport pavement overlays and a preparation method thereof. Background technique [0002] Asphalt concrete pavement has good road performance such as smoothness, shock absorption, and skid resistance, as well as the advantages of high mechanization, short construction period, and convenient maintenance. Therefore, it is widely used in large civil airports. However, with the advent of a new generation of large passenger aircraft such as the A380 and the rapid growth of traffic volume, a series of early diseases have appeared on the asphalt pavement. The original technology cannot meet the strength and durability requirements of the airport pavement, and new mixture preparation technology is urgently needed to solve new problems. [0003] Among the asphalt pavement diseases of civil airports in China, wheel rutting...
