It is swollen, promote Silica hydrogel hole to extend, then the drying under freezing environment, Silica hydrogel is further expanded by solid phase water sublimate, is made
With space net structure using gas as decentralized medium, high porosity, high-specific surface area, low thermal conductivity, low-density it is swollen
Swollen Silica hydrogel recycles the capillary force of expansion Silica hydrogel to be adsorbed on using the tetradecane as phase-change heat-storage material closely knit solidifying in hole
Glue, and encapsulated by Plexol 201, in the case where the mesoporous capillary of Silica hydrogel and hole partition block double action, adsorbed
Tetradecane molecular motion it is limited, reach phase transition temperature and remain to keep stable shape without leaking, to obtain with ten
The good composite phase-change material of shaping effect that four alkane are phase-change material, Silica hydrogel is carrier matrix improves temperature control performance and carries
High intensity, while water-proof function is had both, it is filled in the partial interior gap in asphalt, increases the hair of asphalt
Bulk density, and the voidage and void in mineral aggregate of asphalt are reduced, it can be applied to pitch to substitute fine aggregate
In mixture, the controllable phase-change thermal storage asphalt of volume is formed, active response environment temperature change realizes heat accumulation cooling
Effect；
（2）High-temperature stability of the present invention is good, it can be achieved that actively reduce bituminous paving temperature under hot conditions, not only reduces road surface
Thermal stability disease, and reduce road surface to function of environment heat emission, ambient temperature is reduced, urban heat land effect is alleviated, is improved
Living environment or even energy saving, realization people residence, traffic, environment harmony.
