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(duì)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(duì)混合料的性質(zhì)影響尤為重要，過(guò)少的瀝青用量會(huì)使混合料達(dá)不到相關(guān)的指定規(guī)范，過(guò)多的用量會(huì)使混合料不僅達(dá)不到相關(guān)規(guī)范，還形成糟蹋，也不經(jīng)濟(jì)，路面改進(jìn)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(duì)摻加水泥的瀝青混合料有很大的影響，當(dāng)含水量不足時(shí)，水泥不能在混合猜中完全水化和水解，發(fā)揮不了水泥對(duì)混合料的安穩(wěn)作用，影響強(qiáng)度的形成，含水量偏大會(huì)有水分流出，水泥的有用成分隨水流走，導(dǎo)致抗壓強(qiáng)度下降;含水量過(guò)大還會(huì)形成摻加水泥的瀝青混合料的干縮問(wèn)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(qiáng)度是在一系列雜亂的物理、化學(xué)反應(yīng)過(guò)程中逐步形成的，而這些反應(yīng)過(guò)程需要必定的外界條件。必定的溫度和必定的濕度對(duì)摻加水泥的混合料的強(qiáng)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(duì)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(shí)，對(duì)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(chǎng)冷再生底層（底底層、面層）成本費(fèi)主要為機(jī)械費(fèi)用和添加劑費(fèi)用，人工費(fèi)與其他底層的施工根本相同。現(xiàn)場(chǎng)冷再生工藝與其他半剛性底層資料相比，節(jié)省了以下費(fèi)用：舊路面銑刨及外運(yùn)費(fèi)用、底層（底底層、面層）的原資料費(fèi)用、原資料的運(yùn)輸費(fèi)用、縮短施工周期的費(fèi)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.
