摘要:

傳統(tǒng)熱拌瀝青混合料由于需要在較高溫度下生產(chǎn)和施工，不僅會(huì)消耗大量的能源，而且還會(huì)嚴(yán)重影響環(huán)境質(zhì)量。因此，如何降低瀝青混合料的拌合溫度、減少污染與能耗，已成為道路工程界研究人員共同關(guān)注的科學(xué)問(wèn)題和技術(shù)熱點(diǎn)。溫拌瀝青混合料的出現(xiàn)為該技術(shù)難題提供了一種新穎、高效的解決思路�；�于此，較為全面地介紹了溫拌瀝青混合料的發(fā)展歷程，綜述了國(guó)內(nèi)外已有的溫拌技術(shù)及其工作原理，評(píng)價(jià)了溫拌瀝青混合料的路用性能，闡述了制備溫拌瀝青混合料的新技術(shù)和新進(jìn)展。以期為道路工程界工程師在合理運(yùn)用溫拌技術(shù)設(shè)計(jì)瀝青混合料和啟發(fā)學(xué)者探索瀝青混合料溫拌技術(shù)的新方法、新方向等方面提供幫助。

Abstract:

Due to its preparation and construction process being under relatively high temperature, traditional hot mix asphalt would result in not only a lot of energy consumption but also serious environmental pollution. Therefore, how to reduce the mixing temperature of asphalt mixture, as well as decrease environmental pollution and energy consumption, has become a common scientific issue and a technical hotspot for the researchers in road engineering area. The emergence of warm mix asphalt (WMA) has provided a novel and efficient solution for this technical problem. In the present work, the development history of WMA was introduced comprehensively. The warm mixing technologies existed worldwide and their technical mechanisms were summarized. The pavement performance of WMA was evaluated, and its novel preparation technologies and progress were described. It is in the hope that this paper could be helpful for the engineers to utilize the warm mixing technologies properly in designing asphalt mixtures and researchers to explore the new methods and directions of warm mixing technologies.
