摘要
最大理论密度是沥青混合料设计中计算试样体积指标需要的重要参数,它的确定方法一般有两种,即计算法和实测法。通过对水发泡温拌沥青混合料及水发泡温拌再生沥青试样的最大理论密度进行实测,并与计算值进行比较和分析,提出了针对它们最大理论密度的确定方法。
The maximum theoretic density is a very important parameter for asphalt mixture design in calculating sample volume indicators. The maximum theoretic density of asphalt mixtures is normally obtained by either cal- culation or actual measurement. In this study, the warm mix asphalt （WMA） by water foaming technology and its recycled pavement asphalt mixtures were examined and compared with regarding to the maximum density via both calculating and measuring methods. The determination of the theoretical maximum density of warm mix asphalt mixtures was proposed.
