It is found that UIFR with softening point of 90℃, OH value of 32mg KOH/g andM of 377 g/mol is synthesized when molar ratio of isobutyraldehyde to formaldehyde is 1.5, molar ratio of aldehyde to urea is 6, vacuum distillation temperature and time is 140℃ and 1 h respectively. The terpolycondensate is soluble in most solvents, of paints and exhibits excellent yellowing-resistance.

The properties of the SBR-modified asphalts were compared with that of SBS-modified asphalt before and after adding sulfur.

与SBS改性沥青正好相反，后者的低温性能较好，高温性能较差，表现为软化点低，高温动态力学性能较差，具有很高的低温延度。

Based on parameter of softening point, aging kinetics model was established to show aging condition of two asphalts and to calculate activation energies.

同时以软化点为参数建立老化动力学模型来反映两种沥青的老化情况，并计算出活化能。

Both Na-MMT and OMMT can be able to increase the softening point and viscosity of asphalts, but OMMT had a better modification effect.

Na-MMT和OMMT均可增大沥青的软化点和粘度，明显提高沥青的耐高温性能，但OMMT改善效果更为显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
