1、設計方面的建議:
1. Design recommendations:
1)、泡沫瀝青再生結構層的功能范圍:可利用舊路面的全部瀝青層材料用作路面的上基層(或下面層)結構;也可利用舊路面的瀝青層及原水穩基層混合再生形成新的柔性基層。
1), the functional range of the foamed asphalt regeneration structure layer: all the asphalt layer materials of the old pavement can be used as the upper (or below) structure of the road surface; The asphalt layer of the old pavement and the raw water stabilized base can also be mixed and regenerated to form a new flexible base.
2)、泡沫瀝青再生結構層的上、下功能層的設置:一般泡沫瀝青再生結構層作上基層結構的,再生層與水穩基層之間可采用透層;泡沫瀝青再生結構層上應采用瀝青封層的功能層設計。
2), the upper and lower functional layers of the foamed asphalt regeneration structure layer: the general foamed asphalt regeneration structure layer is used as the upper base structure, and the regeneration layer and the water stable base can be permeable. The functional layer of asphalt seal should be used in the regeneration layer of foamed asphalt.
3)、泡沫瀝青結構層的厚度:泡沫瀝青再生結構層具備相應結構的強度,根據工程實際使用情況,建議廠拌泡沫瀝青冷再生設計厚度不小于10cm為宜。
3) the thickness of foam asphalt structural layer: the structure of foamed asphalt regeneration has the strength of the corresponding structure. According to the actual application of the project, it is suggested that the cold recycled design thickness of the plant foamed asphalt is not less than 10cm.
2、施工方面
2. Construction aspect
1)、瀝青材料的控制:應采用配合比設計階段取樣選用及施工前取樣檢測的方法,確保瀝青性能滿足泡沫瀝青的使用要求。
1) control of Bituminous Materials: the sampling method in the mix design stage and the sampling inspection before construction should be adopted to ensure that the performance of the asphalt meets the requirements of the foamed asphalt.
2)、新添材料的控制:為改善泡沫瀝青的級配,提高結構層抵抗變形的性能,泡沫瀝青混合料中一般應新添百分之10-百分之20碎石材料。如有兩種及以上的新添材料,應采用連續式計量設備進行配料,以確保材料摻配的均勻性。
2) control of newly added materials: in order to improve the gradation of foamed asphalt and improve the performance of resisting deformation of the structural layer, 10- twenty percent gravel material should generally be added to the foamed asphalt mixture. If there are two or more new materials, continuous metering equipment shall be used for batching to ensure the uniformity of material mixing.
3)、混合料的離析現象:應從混合料出料到攤鋪環節采取措施避免混合料的離析現象的產生。
3) Segregation of mixture: Measures shall be taken from discharge to paving to avoid segregation of mixture.
