Determination of groove and mechanical properties of underside shaped concrete paver

This paper presents an innovative paver with groove beneath the normal rectangular paver,named as the underside shaped concrete paver (uscp). a known fact,there is less friction between surface at beneath of paver and bedding sand. therefore,uscp provide their own grip to bedding sand especially during compaction process. the process of groove determination was first performed before the uscp were tested for compression and flexural strength. the groove was determined based on the theory of bending stress. combined with several factors,the basic groove shapes chosen were rectangular and triangular. results indicated that some groove shapes are better in compression,but have weak flexural strength and vice versa. in fact,the relationship between mechanical properties and groove shape is indisputable. it is hoped that the outcomes can be considered in the future to design desirable paver. © 2016 penerbit utm press. all rights reserved.
