冷再生機租賃：瀝青路面冷再生技術的環(huán)境、經濟及性能綜合評估
來源：http://www.baitaiglass.com/ 日期：2026-01-04 發(fā)布人：
1. 采用乳化瀝青粘合劑（CCPREA）對路面進行冷再生較使用泡沫瀝青粘合劑（CCPRFA）具有更大的環(huán)境影響。
1. Using emulsified asphalt binder (CCPREA) for cold recycling of pavement has greater environmental impact than using foam asphalt binder (CCPRFA).
2. CCPREA的總生產成本比CCPRFA高出37.4%。
2. The total production cost of CCPREA is 37.4% higher than that of CCPRFA.
3. CCPREA在劈裂抗拉強度、馬歇爾穩(wěn)定度保持率和疲勞壽命三項關鍵指標上均優(yōu)于CCPRFA。
CCPREA outperforms CCPRFA in three key indicators: splitting tensile strength, Marshall stability retention, and fatigue life.
4. 在整體可持續(xù)性評估中，CCPREA 的得分為 0.52，略高于CCPRFA 的 0.48 分。
In the overall sustainability assessment, CCPREA scored 0.52, slightly higher than CCPRFA's 0.48.
瀝青路面因其行駛平順性好、輪胎-路面噪聲低、施工周期短等優(yōu)勢，在全球范圍內廣泛應用。然而，老化瀝青路面的養(yǎng)護與修復會產生大量銑刨料，若采用傳統(tǒng)露天堆放或填埋處置方法，不僅污染環(huán)境，還會阻礙瀝青等資源的回收利用。廠拌冷再生技術（CCPR）能有效延長道路壽命至15~20年，主要包括乳化瀝青冷再生（CCPREA）和泡沫瀝青冷再生（CCPRFA）兩種技術路徑?，F(xiàn)有研究雖已通過生命周期評估（LCA）分析了CCPR的環(huán)境影響，但針對CCPREA與CCPRFA在環(huán)境、經濟及性能三方面的綜合對比仍顯不足。為此，本研究構建了一套可持續(xù)性評估框架，通過系統(tǒng)比較兩種技術路徑，為未來基礎設施項目的技術選型提供科學依據(jù)。
Asphalt pavement is widely used worldwide due to its advantages such as good driving smoothness, low tire road noise, and short construction period. However, the maintenance and repair of aging asphalt pavement will generate a large amount of milling materials. If traditional open-air stacking or landfill disposal methods are used, it will not only pollute the environment, but also hinder the recycling and utilization of asphalt and other resources. The plant mix cold recycling technology (CCPR) can effectively extend the road life to 15~20 years, mainly including two technical paths of emulsified asphalt cold recycling (CCPREA) and foam asphalt cold recycling (CCPRFA). Although existing research has analyzed the environmental impact of CCPR through life cycle assessment (LCA), there is still a lack of comprehensive comparison between CCPREA and CCPRFA in terms of environment, economy, and performance. To this end, this study has developed a sustainability assessment framework that provides a scientific basis for the technology selection of future infrastructure projects by systematically comparing two technological paths.
瀝青路面冷再生技術主要采用乳化瀝青粘合劑（CCPREA）和泡沫瀝青粘合劑（CCPRFA）兩種材料并添加水泥對路面進行再生。這類技術因其顯著的環(huán)保效益和資源節(jié)約優(yōu)勢而廣受青睞。盡管優(yōu)勢明顯，建立一套系統(tǒng)化的評估體系仍十分必要。本研究構建了一個結合層次分析法（AHP）、熵權法（EWM）和逼近理想解排序法（TOPSIS）的綜合評估模型，從環(huán)境、經濟和工程技術三個維度對這兩種工藝的可持續(xù)性進行了多維度評價。生命周期評估（LCA）結果表明，CCPREA 在溫室氣體排放、能源消耗和經濟成本方面均高于 CCPRFA，但在綜合性能表現(xiàn)上，CCPREA更具優(yōu)勢。多準則評估結果顯示，AHP-EWM-TOPSIS模型對CCPREA的評分為0.62，顯著高于CCPRFA的0.38。
Cold recycling technology of asphalt pavement mainly uses two materials, emulsified asphalt binder (CCPREA) and foam asphalt binder (CCPRFA), and adds cement to regenerate the pavement. This type of technology is widely favored due to its significant environmental benefits and resource conservation advantages. Despite the obvious advantages, it is still necessary to establish a systematic evaluation system. This study constructed a comprehensive evaluation model that integrates Analytic Hierarchy Process (AHP), Entropy Weight Method (EWM), and TOPSIS method to comprehensively evaluate the sustainability of these two processes from three dimensions: environment, economy, and engineering technology. The results of life cycle assessment (LCA) indicate that CCPREA is higher than CCPRFA in terms of greenhouse gas emissions, energy consumption, and economic costs, but in terms of overall performance, CCPREA has more advantages. The multi criteria evaluation results showed that the AHP-EWM-TOPSIS model scored 0.62 for CCPREA, significantly higher than CCPRFA's 0.38.
