INJECTION MATERIAL FOR RAPID HARDENING SEMI-FLEXIBLE PAVEMENT, AND INJECTION MILK USING THE SAME
To provide an injection material for rapid hardening semi-flexible pavement capable of reproducing strength in short time, high in flowability, capable of being injected in a gap of open-graded particle size asphalt mixtures before reproduction of strength, further capable of being used advantageously used as a raw material of injection milk for rapid hardening semi-flexible pavement, in which a pavement body formed by injecting the same into gaps of the open-graded particle size asphalt mixture hardly generates black dot.SOLUTION: There is provided an injection material for rapid hardening semi-flexible pavement containing Portland cement, rapid hardening admixture, a fine aggregate, fly ash, a re-emulsified powder resin, an antifoam agent, and a setting modifier, in which content of the fly ash is more than 5 pts.mass and less than 70 pts.ass based on 100 pts.mass of total amount of the Portland cement and the rapid hardening admixture, and the fly ash has L value in a Hunter colorimetric system of 50.0 or more, ignition loss of 4.0 mass% or less, and methylene blue adsorption amount of 0.80 mg/g or less.SELECTED DRAWING: None
【課題】短時間で強度を発現することができ、かつ流動性が高く、強度が発現する前に開粒度アスファルト混合物の空隙に注入することができ、さらに開粒度アスファルト混合物の空隙に注入して形成した舗装体は黒斑が発生しにくい速硬型半たわみ性舗装用注入ミルクの原料として有利に用いることができる速硬型半たわみ性舗装用注入材を提供する。【解決手段】ポルトランドセメント、速硬性混和材、細骨材、フライアッシュ、再乳化粉末樹脂、消泡剤、凝結調整剤を含む速硬型半たわみ性舗装用注入材であって、前記ポルトランドセメントと速硬性混和材の合計量１００質量部に対する前記フライアッシュの含有量が５質量部以上７０質量部以下の範囲内にあり、前記フライアッシュは、ハンター表色系におけるＬ値が５０．０以上であって、強熱減量が４．０質量％以下であり、メチレンブルー吸着量が０．８０ｍｇ／ｇ以下である速硬型半たわみ性舗装用注入材。【選択図】なし
