AN EXAMINATION OF APPLICATION OF CONCRETE BLOCK PAVEMENT TO HEAVY-ROAD FIELDS

Abstract

The purpose of the series of our study, including this paper, is to clarify the base structure and the functions of the sand layer and jointing sand in the concrete block pavement and the conditions required of them, and to use the obtained results as the basic data for the design method to apply the concrete block pavement to heavy-load fields. In this paper, the structures of the jointing sand and various bases under moving loads are examined by using a load simulater which can evaluate the pavement under conditions similar to the actual running cars.
