A RESEARCH ON THE DE-ICING FLUID TO THE DURABILITY EFFECT OF THE AIRPORT CEMENT CONCRETE PAVEMENT AND THE MEASURES OF PREVENTION

摘要

In recent years, the durability destruction in the cement concrete pavement appears to different degrees in a lot of the airports that locate in the northeast of China, the northwest of China and the north China. It is typically showed in that the pavement surface peels and the depth of destruction reaches more than 10cm in some parts. It does have some harmful effects in the regular use of airports and the appearance of the pavement. A lot of airports have to spend much money on mending it. In order to find out the real reason of the durability destruction and take efficient measures directed against it to clear up or to reduce the concealed damage, the research group began the research on it in 1998. By means of on-the-spot investigation and research as well as the experiment research that lasted for half a year, they have obtained a large amount of the first-hand information and clarified the reason of the pavement destruction on the whole, and then they came up with the main measures of prevention.
