The order contact of skeleton is similar to that of common traffic and is suitable to be kept between 1.07 and 1.15. When adopting dynamic stability index to evaluate the high temperature performance of asphalt mixture, it is likely to stretch the work of modified asphalt and there is a discrepancy between the capacity to evaluate different gradation designs and the practical facts. In the late process of creep, stiffness module index can evaluate the high temperature performance of asphalt mixture which is relatively objective. The rutting prediction model based on this is relatively reliable.

采用车辙动稳定度指标评价沥青混合料高温性能时，可能夸大了改性沥青的作用，其对不同级配优劣的鉴别能力与实践事实间也存在一定的差异，而蠕变劲度模量指标能够较为客观地评价沥青混合料的高温稳定性能，且在此基础上建立的车辙预估模型经实践检验具有较高的可靠性。

To conduct such research a new experimental apparatus was established.With this setup the two-photon excitation spectra of Barium and one-photonexcitation spectra of Strontium Rydberg atoms were recorded and identified.The Stark spectra of Strontium atoms showed the "l-mixing" and "n-mixing"features. By changing laser wavelength and external electric field strengthsimultaneously, the scaled-energy spectra of Strontium 〓 Rydberg atomsat constant scaled-energy ε=-3.00,-2.50 and -1.88 were recorded for thefirst time. The experimental spectra were Fourier transformed and yielded therecurrence spectra.

The results show that, using the cement as a filler, there are no impacts on the high temperature performance, neither do the marshell stability and the split strength; nor the residual stability and the TRS are highly improved, even exceed the original mixture, which explains that using the cement as a filler also is used for the asphalt mixture with PR.

试验结果表明，采用水泥替代矿粉作为填料后，对掺加PR.S添加剂沥青混合料的高温性能几乎没有影响，其稳定度和劈裂强度也没有明显提高；而其残留稳定度和劈裂强度比却得到了很大的提高，甚至已经超过了未掺加PR.S添加剂时沥青混合料的对应数值。

For understanding the workability and precision of these prediction equations, at first this study not only simulates the MHs of Taipei, Taichung, Kaoshung cities and Kao-ping area but also compares these results with meteorological models of CLAMET and TPAQM. And the comparisons show the high correlation (up to 0.8) between them. When the results of MH prediction equations model are compared with TPAQM, they get higher or lower values than TPAQM. The reasons are that Holzworth method can not concern about the warm and cold advections effect and the upper air data used do not get enough finer space-spread. About the results spread on the domain of my model, they show more different MH fields between the land and the sea around and get more sharply change of the land MHs on daytime than TPAQM.

为了解此预测式之可行性及准确度，本研究针对台北、台中、高雄及高屏地区作混合层高度值的模拟，并将模拟结果与实际观测值、CALMET气象模组及光化学轨迹模式输出结果作比对，结果显示均有0.80以上之高相关性；但与TPAQM计算结果间有明显的高估或低估现象，此为Holzworth method无法考量温度平流效应对混合层发展之影响及探空资料空间解析度不足所致；而在空间分布上，本模式所计算的混合层高度场相较於TPAQM在海陆分布上有较明显的分野，且更能够显示出内陆地区混合层高度的日变化。
