Studies on the applicability of a class III prestressed concrete (PC) slab, in which cracking at the bottom of the slab is permitted, and the development of a new type of PC precast slab with a new jointing system (horn-joint) for airport pavements have been carried out. From the results of theoretical analysis and a series of full scale loading tests on class III PC pavements, it has become clear that a class III PC slab can be satisfactorily used for airport pavements. This type of pavement may be a more rationalized one for heavy aircraft. In addition, the results of a series of full scale loading tests on the PC precast slab pavement connected with horn-joints have shown that this new type of pavement has a sufficient load carrying capacity and can be applied even to pavements subjected to heavy aircraft. Since an allowance for the curing time on in-situ concrete is not necessary in this type of pavement, the construction time is so fast that it may be ideal for the rapid repairs of existing pavements.
