地方道路与高速公路交叉时的保通方案设计及注意事项

摘要

This paper three heating methods for asphalt mixtures for test and compares them with the using upon mixing method. The result shows that heating of asphalt mixtures with microwave technology exhibits advantages that the heating duration is short, materials are evenly heated and various performance indices of the heated mixtures are very close to using upon mixing level, therefore, adoption of microwave technology in stead of drying oven to heat asphalt mixtures is feasible.%目前,越来越多新建的地方道路与已建高速公路交叉.因此,选择合适的保通方案及在保通方案实施过程中采用不同的措施,对于保证高速公路的安全通行极为重要.针对高速公路与地方道路交叉问题,提出相关保通设计方案及注意事项.
