Development of High Durable Grout for Airport Prestressed Concrete Pavement
Many airports in Japan are constructed on the reclaimed lands with dredged soft soil. Ground settlement is anticipated when designing concrete pavement in such airports, so it is recognized as suitable to apply a pavement structure consisted of Prestressed Concrete (PC) slabs and grout underneath. The grout has been injected several times underneath the slabs to compensate the ground settlement, and there have been studies aimed at improving the grout and structure of the PC pavements. However, there are some cases where the grout is pulverized by repeated aircraft loadings. The aim of this study is to improve the grout’s resistance to the pulverization by the addition of aramid fibers to a conventional grout. The authors first investigated the workability of improved fiber-mixed grouts in laboratory test. They then confirmed the workability with a full-scale model and the durability of the grouts by repeated loading.
