本文通过室内试验和现场试验的方式，对辉绿岩作为沥青混凝土上面层集料的应用进行研究，得出了辉绿岩集料的各种物理、力学性质，辉绿岩拌制的沥青混合料的各项指标，试铺路段各种路用指标，证明了辉绿岩作为沥青混凝土上面层集料是完全可行的；最后提出辉绿岩作为沥青混凝土上面层集料应用的施工工艺。

During aging, Gastel index which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.

彩色沥青老化过程中，沥青胶体不稳定指数对沥青老化条件很敏感，随老化温度的升高和老化时间的延长而增加；粘度随老化时间的延长近似呈指数关系增加，所以可以用胶体不稳定指数和老化指数来评价彩色沥青的老化性能。

It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。
