我国高原地区机场水泥混凝土道面普遍存在冻融病害,大部分高原机场在投入运行很短时间内就大面积出现冻融病害。冻融病害由于缺乏经济有效的处置方法,其对机场维护带来很大压力,后期道面表层混凝土会出现剥落进而产生FOD,成为机场运行重要危险源,严重影响飞机起降安全。 Freezing-thawing diseases are common to cement concrete pavements in airport plateau in our country. Most of the plateau airports are exposed to freeze-thaw disease in a very short period of time. Freezing and thawing diseases due to the lack of cost-effective disposal methods, which bring great pressure on the maintenance of the airport, the latter part of the surface layer concrete spalling will produce FOD, become an important airport operation risk source, seriously affecting the aircraft taking off and landing safety.
