Description
Technical Field
The invention relates to the field of composite modified emulsified asphalt and ballast track bed stabilization, in particular to modified emulsified asphalt for ballast track bed stabilization and a preparation method thereof.
Background
The track structure commonly used for the existing railway is divided into a ballast track and a ballastless track, wherein the ballast track has large elasticity and strong deformation recovery after stress, and is a track structure commonly used for a large temperature difference region. However, when a train rapidly passes through the structure, the ballast flying phenomenon is easily generated due to aerodynamics, and the running safety of the train is seriously influenced. In contrast, although the ballastless track is widely applied to a high-speed rail line, the ballastless track is difficult to repair after being damaged due to poor elasticity, and the additional power is significantly increased when a train passes through the area unlike the under-rail support condition of a tunnel bridge, thereby adversely affecting the driving stability and riding comfort. Therefore, in recent years, railway researchers try to stabilize the ballast of the ballast track by using some materials, for example, in patent 201720594557.1, the polyurethane material is used for curing the ballast, so as to overcome the defect of ballast splashing of the ballast track, and enable the track to have the elasticity of the ballast track and the stability and maintenance-free performance of a ballastless track. The existing research shows that the polyurethane has low bonding strength and good toughness, can achieve the effect of preventing ballast from flying and not influencing tamping operation after spraying, and can increase the ballast resistance to a certain extent and improve the ballast stability by stabilizing the ballast track with the polyurethane. However, the polyurethane itself is expensive, and the ballast is required to be clean and dry before stabilizing the ballast bed, which adds extra cost and burden to the construction operation, so that the polyurethane is generally only paved in long and large steel bridges, special foundations, and areas with difficult maintenance and repair. Therefore, in order to increase the simplicity of ballast track stabilizing construction and reduce the ballast curing cost, the goal of stabilizing the ballast track in the whole section is achieved, and a novel ballast track bed material for stabilizing the ballast track is urgently needed to be developed.
The emulsified asphalt has good rheological property at normal temperature, low viscosity and low price, is an important material for realizing cold repair and improving strength, but the common emulsified asphalt has low initial strength, poor aging resistance and slow curing time, and can generate the problems of poor stabilizing effect and no solidification after being singly applied to a ballast track bed. According to the explanation of the Chinese patent 200610036564.6, the epoxy resin has good thermal stability and strong cohesive force, the strength after quick setting is obviously improved, and the modification of the emulsified asphalt by the epoxy resin can not only improve the cohesiveness of the asphalt and stone, but also shorten the curing time of the emulsified asphalt. Therefore, it is conceivable to add an epoxy resin to the emulsified asphalt. The service life of the high-speed railway roadbed is designed to be 100 years, while the service life of the highway is 15 years, so that the railway has higher requirement on the durability of the emulsified asphalt, and the emulsified asphalt for curing the railway ballast needs to be systematically designed from the aspect of the service life. Researches show that in the aging process of the reclaimed rubber modified asphalt containing the deeply degraded rubber powder, part of carbon black in the rubber powder is separated out and attached to the surface of the asphalt, and the asphalt can be prevented from aging to a certain extent. Therefore, aiming at the defects of the existing ballast track bed material for stabilizing the ballast track, the invention considers that the reclaimed rubber modified asphalt is adopted as the base asphalt, and the emulsified reclaimed rubber modified asphalt is modified for the ballast track bed, so that the asphalt has higher strength and stability, and meanwhile, the aging resistance is obviously improved, and the asphalt has wide prospect when being applied to the ballast track bed.
