In order to investigate the reasonable pavement structure for rapid construction of airstrip, the performance of fiber grid cement soil runway base has been researched through a large number of inside geotechnical experiments and full scale tests. Inside geotechnical experiments results are shown to be as follows: the 7d dry unconfined compression strength of 10% and 12%(by mass) cement soil reach around 3MPa, while saturated unconfined compression strength reach up to 2MPa, and the water stability coefficient reach to 70%. It shows that, the strength characteristic and water stability of cement soil can satisfy the construct demand of airstrip. Full scale test results show that: glass fiber grid improves the holistic elastic modulus of pavement; significantly reduces the drying shrinkage crack and effectively controls the crack development. Holistic elastic modulus runs up to 1906843508MPa at different periods, the increase margin up to 175%, and the rebound deflections less than 1mm under ten thousands traffic times. Contrast test shows that glass fiber grid cement soil base can meet the construction and operation requirements of airstrip with strong bearing capacity, good deformation resistance, and high integrity.
