Abstract
This paper analysed the unique climatic characteristics of Qinghai-Tibet plateau and the durability requirements of airfield pavement concrete, improved the frost resistance, impermeability and abrasion resistance of pavement concrete by mixing air-entraining and water-reducing admixtures. The relations of content of the air-entraining admixture, strength and frost resistance of concrete were tested systematically in laboratory, the appropriate air content was put forward. The tests shown that the frost resistance, impermeability and abrasion resistance fulfilled the requirements of the plateau airfield pavement. In the field of Yushu Airfield in Qinghai, it studied the raw materials selecting, control of air content and construction technics, ensured the durability of the pavement concrete and gained well effect.
