abstract
the use of a broad range of asphalt additives is a well-established practice in road pavement engineering for the production of high-performance hot-mix and warm-mix asphalt mixtures. the study aimed to verify and to assess, though an analytical-sensory approach based on artificial olfactory system (aos), the effects of five different asphalt additives (chemical additives, odor suppressant agent and wax modifiers) on the odorous patterns of asphalt emissions at typical mixing and laying temperatures. the aos has made possible to identify a specific odor fingerprint of each additive. however, once added to asphalt, these agents did not establish with binder effects of synergy, additivity or antagonism, but appear to be as neutral elements by an odorous point of view. the odorous patterns of emissions generated by heating neat asphalt at various temperatures in laboratory scale tend to coincide with those of asphalt/additive mixtures, underlining how the bituminous binder odor resulted to be hiding or masking compared to that of only-additives.
在道路路面工程中,广泛使用沥青添加剂是生产高性能热拌沥青混合料和温拌沥青混合料的一种成熟做法。本研究旨在通过基于人工嗅觉系统(aos)的分析感法,验证和评估五种不同沥青添加剂(化学添加剂、抑臭剂和蜡改性剂)对典型混合和铺设温度下沥青散发气味模式的影响。aos可以识别每种添加剂的特定气味指纹。然而,一旦添加到沥青中,这些药剂并没有形成协同作用、加成作用或拮抗作用的结合效应,而是从气味的角度看,它们似乎是中性元素。在实验室规模的不同温度下加热纯沥青所产生的恶臭排放模式往往与沥青/添加剂混合物的恶臭排放模式一致,强调了沥青粘合剂的恶臭是如何导致与仅添加剂相比隐藏或掩盖的。
