Description of the Related Art Generally, in cold regions, when the temperature of a pavement is immediately below 0 ° C. after being constructed, the surface is frost-damaged and the pavement surface is deteriorated and worn to damage. Due to the frost damage received immediately after such construction, there was a problem in semi-flexible pavement construction during the severe cold season. Further, for example, there is scaling frost damage found in abutments and pier concrete of expressways, and further, antifreezing agents (calcium chloride, sodium chloride) used for winter snow and ice countermeasures cause scaling frost damage. The antifreeze agent causes deterioration of the concrete surface. Such scaling frost damage may also occur in the pavement concrete.

ある。The cement-based milk to be injected into the voids of the pavement requires a large amount of kneading water in order to ensure fluidity, and as a result, it is necessary to impart frost damage resistance.
In particular, in a cold district, as snow melting agent, CaCl 2 and NaCl is sprayed, in particular, CaCl 2 penetrates the paving cement matrix, which cause surface degradation. There is a possibility that it may penetrate into the pavement cement matrix (concrete), deteriorate the surface of the pavement portion, and accelerate the deterioration of the pavement itself, resulting in early rutting.

ない。The frost-damage-preventing grout material of the present invention is injected into the open particle size asphalt concrete voids to prevent the above-mentioned frost damage phenomenon. That is, the synthetic emulsion contained in the cement quick hardening material is CaCl 2 which is a snow melting agent.
Prevents frost damage to concrete pavement with NaCl and NaCl. That is, by adding 10 to 15% by weight of the synthetic resin emulsion stock solution, the surface texture becomes dense, the migration of water from the surface of the cured body to the inside is reduced, and a cured body that is strong against frost damage is formed. You can In addition, even if the temperature is below zero after the construction by using this setting regulator, the strength development is extremely good, so the structure of the hardened body is strengthened, the frost resistance is improved, and the traffic is opened. Is no problem.

きる。The synthetic resin emulsion stock solution mainly used in the frost damage prevention grout material of the present invention is preferably a vinyl acetate type, an acrylic type or an SBR type, and is a fine powder having a small apparent specific gravity. Therefore, it seems that the snow-melting agents CaCl 2 and NaCl agents floating on the surface of the infused milk help prevent the corrosion of the concrete. In addition, it mixes fine powder silica sand and promotes smooth kneading with water. The re-emulsifiable synthetic resin emulsion used in the present invention is sufficiently kneaded with water and can be used in the same manner as the synthetic resin emulsion.

調整剤では、低温では、効果がなかった。The amount of the synthetic resin emulsion contained in the frost damage-preventing grout material of the present invention is preferably 10 to 15% by weight as a stock solution. If it is less than 10% by weight, it may not be sufficient to prevent frost damage and may not be sufficient to prevent infiltration of snow melting chemicals. Further, if it exceeds 15% by weight, it is uneconomical even if the amount is further increased. Furthermore, as the rapid hardening material, a calcium-aluminate-based baking component and an anhydrous gypsum mixture-based rapid hardening material can be added. Examples of the coagulation modifier include one or more kinds of oxycarboxylic acids or salts thereof, alkali metal carbonates, particularly sodium salts, aluminate metal salts, particularly sodium salts, alkali metal sulfates, sodium salts and potassium salts, and oxy. Dicarboxylic acid or tartaric acid, citric acid, gluconic acid or salts thereof are used. Conventional setting regulators were ineffective at low temperatures.
