等级道路

SBR改性沥青具有优良的低温性能，广泛应用于高等级道路的铺筑中。

The SBR modified asphalt which has good low temperature property is widely used for high grade road paving .

CRCP与目前公路交通运输日益大流量、重型化的发展趋势相适应，在重交通高等级道路中有广阔的应用前景。

CRCP accords with the trend of highway transportation of containerization , heavy load and large traffic volume , and it has a vast application in high-grade highways in the future .

根据Logit模型和交通阻抗函数分析出公交专用道将有助于优化城市居民出行交通结构；指出不同等级道路交通流车辆组成将重新分配。

It points out that bus lanes will contribute to optimize the structure of urban resident trips on the basis of Logit model and traffic resistance function , and re-distribute traffic flow on different grades of urban roads .

在总结桥头引道路面管理的特点和决策要素的基础上，通过用户需求分析、系统设计和软件编制等工作，开发了高等级道路桥头引道沉降处理决策辅助系统（ASTDAS）。

On the basis of study of the management characteristics and decision elements of approach pavements , an approach settlement treating decision aided system ( ASTDAS ) is developed .

再生骨料可用于地基加固、低等级道路的级配垫层等部位，设计强度等级不宜高于C20，若需配制较高强度等级的混凝土，还应经相应试验，以验证其质量。

Reclaimed aggregate could be used to strengthen foundation or used as base course for low grade highway etc. The design strength of it should not be higher than C20.If necessary to make concrete batch of higher strength , correspondent experiment shall be made to examine the quality .

对于时段拥堵时长比指标，将不同等级道路的车辆行驶时间（VHT）作为权重，通过加权得到累积严重拥堵路段时长比，确定高峰和平峰的筛选比例参数为50%。

For the index of congestion duration ratio , by using vehicle hour traveled ( VHT ) on different road classes as weights for calculation of the accumulated congested durations , it determined that the screening thresholds for peak and off-peak period are50 % .
