瀝青混合料對于冷再生效果影響因素是什么？
來源：http://m.baitaiglass.com/ 日期：2021-09-09 發(fā)布人：
包含土的成分和品種的影響和瀝青混合料的組成結構類型的影響。混合料按照顆粒尺度分布狀況的不同，能夠分為三種物理狀況：懸浮一密實結構、骨架一空地結構、密實一骨架結構：
It includes the influence of soil composition and variety and the influence of asphalt mixture composition and structure type. According to different particle size distribution, the mixture can be divided into three physical conditions: suspension dense structure, skeleton open space structure and dense skeleton structure:
水泥的礦物成分和分散度對水泥安穩(wěn)土的安穩(wěn)效果有顯著影響。
The mineral composition and dispersion of cement have a significant impact on the stability effect of cement stabilized soil.
瀝青品種和用量對混合料的性質影響尤為重要，過少的瀝青用量會使混合料達不到相關的推薦規(guī)范，過多的用量會使混合料不僅達不到相關規(guī)范，還形成糟蹋，也不經濟，路面改進效果也不是很顯著。
Asphalt variety and dosage have a particularly important impact on the properties of the mixture. Too little asphalt dosage will make the mixture fail to meet the relevant specified specifications. Too much asphalt dosage will not only make the mixture fail to meet the relevant specifications, but also form waste and uneconomical. The effect of pavement improvement is not very significant.
含水量對摻加水泥的瀝青混合料有很大的影響，當含水量不足時，水泥不能在混合猜中完全水化和水解，發(fā)揮不了水泥對混合料的安穩(wěn)作用，影響強度的形成，含水量偏大會有水分流出，水泥的有用成分隨水流走，導致抗壓強度下降;含水量過大還會形成摻加水泥的瀝青混合料的干縮問題。
The water content has a great impact on the asphalt mixture mixed with cement. When the water content is insufficient, the cement cannot be fully hydrated and hydrolyzed in the mixing process, which can not play the role of cement in the stability of the mixture and affect the formation of strength. The water content tends to flow out, and the useful components of cement go with the water flow, resulting in the decrease of compressive strength; Excessive water content will also form the problem of dry shrinkage of asphalt mixture mixed with cement.
摻加水泥的瀝青混合料的強度是在一系列雜亂的物理、化學反應過程中逐步形成的，而這些反應過程需要必定的外界條件。必定的溫度和必定的濕度對摻加水泥的混合料的強度的形成是有利的。
The strength of asphalt mixture with cement is gradually formed in a series of chaotic physical and chemical reactions, which require certain external conditions. A certain temperature and humidity are beneficial to the formation of the strength of the mixture mixed with cement.
一般的水泥安穩(wěn)土對集料壓碎值有必定的要求。用水泥和乳化瀝青再生舊瀝青路面材料時，對集料的壓碎值相同也有必定的要求。
General cement stabilized soil has certain requirements for aggregate crushing value. When recycling old asphalt pavement materials with cement and emulsified asphalt, there are certain requirements for the same crushing value of aggregate.
瀝青混凝土舊路現(xiàn)場冷再生底層（底底層、面層）成本費主要為機械費用和添加劑費用，人工費與其他底層的施工根本相同。現(xiàn)場冷再生工藝與其他半剛性底層資料相比，節(jié)省了以下費用：舊路面銑刨及外運費用、底層（底底層、面層）的原資料費用、原資料的運輸費用、縮短施工周期的費用等。
The cost of cold recycled bottom layer (bottom layer and surface layer) of old asphalt concrete road is mainly machinery cost and additive cost, and the labor cost is basically the same as that of other bottom layers. Compared with other semi-rigid bottom layer materials, the on-site cold regeneration process saves the following costs: milling and outward transportation costs of old pavement, raw material costs of bottom layer (bottom layer, surface layer), transportation costs of raw materials, costs of shortening construction cycle, etc.
