Application of Newly Developed Prestressed Concrete Pavement Technology in Japanese Airports

Paper by SATO HTWHIYD LNUKAI from ISCR 7th 1994 Vienna Austria

Many researches on prestressed concrete (PC) pavements have been conducted. The applicability of a class Ill PC slab, in which cracking at the bottom of the slab is permitted, was confirmed for airport pavements. A new type of PC precast slab pavement with new jointing systems was developed. A new lift-tip method was developed for adjusting the unevenness of PC pavements when they have unacceptable settlement and differential settelment. These kinds of new PC pavement technology have been recently often applied in many Japanese airports. This paper describes the procedure of developing the new PC pavement technology and its applications Lu airports.
