關(guān)于冷再生總是會有很多種問題。今天小編來為大家介紹下什么是冷再生材料成形?
There are always many problems with cold regeneration. Today, I'd like to introduce to you what is cold recycled material forming?
冷再生材料的性質(zhì)與傳統(tǒng)道路材料不完全相同,因而對成形的要求也不完全相同。冷再生材料按再生劑大致可以區(qū)分為兩類:無機再生劑和瀝青再生劑,瀝青再生時往往加入少量水泥以提高其抗水損壞能力。常用的無機再生劑是水泥,其他還有二灰、水泥粉煤灰等。
The properties of cold recycled materials are not the same as those of traditional road materials, so the forming requirements are not completely the same. Cold recycled materials can be roughly divided into two categories: inorganic recycling agent and asphalt recycling agent. When asphalt is recycled, a small amount of cement is often added to improve its water damage resistance. The common inorganic regenerant is cement, and the others are lime fly ash and cement fly ash.
無機穩(wěn)定冷再生一般按照傳統(tǒng)的半剛性材料進行成形和養(yǎng)生。常溫下進行重型擊實試驗或者震動擊實試驗,在20°C或者25°C下養(yǎng)生7天。通過含水量-強度關(guān)系確定含水量。瀝青穩(wěn)定劑冷再生時的情況比較復(fù)雜,尚無統(tǒng)一方法。冷再生材料組成設(shè)計方法較為常見的方法是用擊實法確定上佳液體量,用馬歇爾穩(wěn)定度、干劈裂強度、濕劈裂強度中的一個或幾個達到優(yōu)來確定瀝青用量。
Inorganic stable cold regeneration is generally formed and cured according to traditional semi-rigid materials. Heavy compaction test or vibration compaction test shall be carried out at room temperature, and the curing time shall be 7 days at 20 ° C or 25 ° C. The water content is determined by the relationship between water content and strength. The situation of cold regeneration of asphalt stabilizer is complex, and there is no unified method. The common method of cold recycling material composition design is to determine the best liquid content by compaction method, and determine the asphalt content by one or more of Marshall stability, dry splitting strength and wet splitting strength.
