交通部公路科学研究所1987年获得了二项国家级、六项部级科技成果奖。这些成果为:1.青藏公路多年冻土地区黑色路面的修筑技术:获国家科技进步一等奖。该项研究难度大,条件艰苦。青藏高原多年冻土地区气候恶劣,工程地质条件复杂,公路病害严重,修筑沥青路面强烈吸热、封水作用,对冻土路基中水,热条件影响极大,处置不当会造成路基、路面过早破坏。为此,交通部组织了七个单位成立青藏公路科研组,集中研究长达12年之久,解决了多年冻土地区修筑沥青路面的路基稳定和沥青路面合理结构设计及施工问题。高海拔、低纬度能在堪称世界屋脊的青藏高原多年冻土地区铺筑长达一千公里以上的沥青路实
The Highway Science Research Institute of the Ministry of Communications won two national and six ministerial scientific and technological achievements awards in 1987. These achievements are as follows: 1. Construction technology of black pavement on permafrost area of Qinghai-Tibet Highway: won the first prize of national science and technology progress. The study is difficult and difficult conditions. The permafrost region on the Qinghai-Tibet Plateau has bad climate, complex engineering geological conditions and serious road diseases. The construction of asphalt pavement is strongly endothermic and sealing water. It has a great impact on water and heat conditions in the subgrade of frozen soil. Improper disposal can cause roadbed and pavement over Early destruction. To this end, the Ministry of Communications organized seven units to set up a research group of Qinghai-Tibet Highway, focusing on research for as long as 12 years to solve the roadbed stability of asphalt pavement construction and rational structural design and construction of asphalt pavement in permafrost regions. High altitude and low latitude can pave the way for more than 1,000 kilometers of asphalt in permafrost areas on the roof of the world
