Abstract

Hotmix performance is very dependent on volumetric characteristics and Marshall characteristics, one of the parameters of which is density. Unmet density will affect other Marshall parameters which can also result in early damage to road pavement. This thesis is the result of research in the field and in the laboratory which aims to analyze the effect of temperature at the stage of exposure, and the stage of compaction as well as the number of compaction paths on the density of pavement AC-WC type IVB Asphalt Institute. Research in the field is divided into two categories that are distinguished at the temperature of the exposure to meet the specification requirements and do not meet. The results showed that there was a tendency that the temperature of the dispersion in the range of requirements had a stronger correlation to get the value of the hotmix density according to the requirements compared to the overlay temperature not in the range of requirements. The regression equation model relates the laying temperature (X1), the initial compaction temperature (X2), and the number of compaction paths (X3) to the hotmix density (Y) obtained are: Y = 82,7 + 0,021X1 + 0,033X2 + 0,409X3.
热混合性能非常依赖于体积特性和马歇尔特性,其中一个参数是密度。未满足密度会影响其他Marshall参数,这也会导致路面的早期损坏。本论文是在现场和室内研究的基础上,分析了暴露阶段温度、压实阶段温度以及压实路径数对AC-WC型IVB沥青路面密度的影响。该领域的研究分为两类,即在暴露温度上区分符合规范要求和不符合规范要求。结果表明,与未在要求范围内的覆盖温度相比,在要求范围内的分散温度对得到符合要求的热混合密度值有更强的相关性。得到的铺层温度(X1)、初始压实温度(X2)、压实路径数(X3)与热熔密度(Y)的回归方程模型为:Y = 82,7 + 0,021X1 + 0,033X2 + 0,409X3。
