A temperature-sensitive anti-freezing material for asphalt pavement and a method for preparing same. A temperature-sensitive macro molecular organic matter is employed in the anti-freezing material instead of a traditional sustained release agent, and coated on the surface of the chloride particle having an anti-icing anti-freezing effect; and then the temperature-sensitive anti-freezing material for asphalt pavement is prepared by sieving and drying processes. The anti-freezing material can automatically respond to and control the release temperature of the chloride in the anti-freezing material according to the outside temperature, increase the anti-freezing effect duration of the chloride in the asphalt pavement effectively, and extend the service lifetime of the anti-freezing material.

The invention provides compositions and methods for sealing subterranean spaces such as natural or induced fractures, vugs or annular spaces. The composition is composed of a base fluid consisting of a soluble alkali silicate, a gas generating additive, solids and a setting agent. The gas generating additive may be coated or uncoated. The gas generating additive may also be in the form of a slurry. In the case of coated additives, the coating may act as a retarder or an accelerator to the expansion and setting agent of the soluble alkali silica. Similarly, the choice of carrier fluid in a slurry may retard or accelerate the expansion and setting of the alkali silicate-based plug.
