1）混合料中土的物理化學(xué)性質(zhì)的影響
1) Influence of physical and chemical properties of soil in mixture
包含土的成分和品種的影響和瀝青混合料的組成結(jié)構(gòu)類型的影響?；旌狭习凑疹w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(shí)結(jié)構(gòu)、骨架一空地結(jié)構(gòu)、密實(shí)一骨架結(jié)構(gòu)：
It includes the influence of soil composition and variety and the influence of asphalt mixture composition and structure type. According to the 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。
The variety and amount of asphalt have a particularly important impact on the properties of the mixture. Too little amount of asphalt will make the mixture fail to meet the relevant specified specifications. Too much amount 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，水泥的有效成分隨水流走，導(dǎo)致抗壓強(qiáng)度下降;含水量過大還會(huì)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 with cement. When the water content is insufficient, the cement can not 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 effective 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)過程中逐步形成的，而這些反應(yīng)過程需要必定的外界條件。試驗(yàn)證明，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. The test shows that 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) on the site of asphalt concrete old road is mainly the cost of machinery and additives, 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: the cost of milling and outward transportation of the old pavement, the cost of raw materials of the bottom layer (bottom layer, surface layer), the transportation cost of raw materials, the cost of shortening the construction cycle, etc.
再生瀝青混合料除了具有一定的經(jīng)濟(jì)效益外，還間接的具有良好的社會(huì)效益和環(huán)境效益，而這些效益是無法用錢銀來衡量的。
Recycled asphalt mixture not only has certain economic benefits, but also indirectly has good social and environmental benefits, which can not be measured by money and silver.
因?yàn)殇佒偕访娑浞掷昧伺f瀝青混合料，解決了瀝青路面翻修所發(fā)生很多廢料對(duì)環(huán)境污染問題，保護(hù)了人類生存的環(huán)境，契合了我國(guó)的可持續(xù)發(fā)展戰(zhàn)略中廢物資源化的要求;因?yàn)楣?jié)省瀝青和砂石材料，削減了對(duì)材料的需求量，又有助于自然資源的保護(hù)，平緩瀝青材料供求的緊張狀態(tài);因?yàn)楣?jié)省了投資，下降了工程造價(jià)，使某些本來不能及時(shí)翻修的舊瀝青路面得以修復(fù)，從而改善了道路情況，提高了公路的運(yùn)輸能力，削減輪胎的磨損，下降運(yùn)輸成本，削減可能發(fā)生的交通事故，確保行車舒適安全。
The old asphalt mixture is fully utilized due to the paving of recycled pavement, which solves the problem of environmental pollution caused by many wastes in the renovation of asphalt pavement, protects the environment for human survival, and meets the requirements of waste recycling in China's sustainable development strategy; Because it saves asphalt and gravel materials, reduces the demand for materials, helps to protect natural resources and ease the tension between supply and demand of asphalt materials; Because the investment is saved and the project cost is reduced, some old asphalt pavements that could not be renovated in time can be repaired, so as to improve the road condition, improve the transportation capacity of the road, reduce tire wear, reduce transportation costs, reduce possible traffic accidents and ensure driving comfort and safety.
