【摘要】:研究了冷補(bǔ)瀝青混合料的成型特性、強(qiáng)度形成原理和過程,提出了冷補(bǔ)瀝青混合料試件的處理方法;摻加消石灰的冷補(bǔ)瀝青混合料具有較大的初始強(qiáng)度和成型強(qiáng)度,分析了養(yǎng)生時(shí)間與穩(wěn)定度及殘留穩(wěn)定度的規(guī)律;發(fā)現(xiàn)標(biāo)號(hào)低的基質(zhì)瀝青制備的冷補(bǔ)瀝青混合料具有較大的初始強(qiáng)度和成型強(qiáng)度;實(shí)際拌制混合料中發(fā)現(xiàn),低標(biāo)號(hào)的混合料施工可操作性方面較差;冷補(bǔ)瀝青中柴油含量基本與初始強(qiáng)度呈現(xiàn)負(fù)相關(guān)的線性關(guān)系,實(shí)際混合料生產(chǎn)過程中一定要優(yōu)選出合適的柴油含量;110℃下烘箱養(yǎng)生溫度能夠較為理想地模擬冷補(bǔ)瀝青混合料的成型。
[Abstract]:The forming characteristics, the forming principle and the process of the cold supplementary asphalt mixture are studied, and the treatment method of the cold supplementary asphalt mixture specimen is put forward. The laws of health preservation time, stability and residual stability are analyzed. It is found that the cold filled asphalt mixture prepared with low grade matrix asphalt has high initial strength and forming strength. The low grade mixture has poor maneuverability in construction, and the diesel oil content in cold filled asphalt has a negative linear relationship with the initial strength. In the process of actual mixture production, it is necessary to select a suitable diesel oil content of 110 鈩,
