Abstract

The invention discloses a temperature regulating system for an asphalt road. The temperature regulating system comprises a heat dissipation or heat absorption device which is arranged in an asphalt road structure layer, wherein one end of the heat dissipation or heat absorption device is connected with an inlet pipeline of a heat transfer medium; the other end of the inlet pipeline of the heat transfer medium is connected with an input heat medium pump; the other end of the heat dissipation or heat absorption device is connected with an outlet pipeline of the heat transfer medium; the other end of the inlet pipeline of the heat transfer medium is connected with an output heat medium pump; and hot water or cool water is pumped into the inner cavity of the inlet pipeline of the heat transfer medium through the medium pump. The system takes away heat of the asphalt road generated at high temperature or transfers heat to the asphalt road at low temperature, makes the asphalt road in outside extreme climate conditions work at the best use ambient temperature, prevents the asphalt under the extreme climate conditions from becoming soft at high temperature or becoming fragile at low temperature, ensures the asphalt road is under the best useable condition, greatly prolongs the service life of the road, and can be widely applied to asphalt roads.

Description

technical field [0001] The invention relates to a road engineering application, in particular to a temperature regulating system for asphalt roads. Background technique [0002] The main forms of damage to asphalt roads in terms of asphalt are rutting due to the softening of the asphalt due to high temperature, and cracking due to the embrittlement of asphalt due to low temperature. [0003] In order to solve the above problems, modified asphalt is commonly used all over the world to solve the problem of asphalt softening at high temperature or brittle at low temperature. In China, SBS thermoplastic rubber modified asphalt with both high and low temperature is generally used. However, due to the great difference between the modifier used in modified asphalt and asphalt, it is difficult for modified asphalt to form a stable colloidal system, and the asphalt road composed of it also has the defects of great differences and even mixed reviews.
