“…The effect of groove depth and groove volume on the USCP' compressive strength, as indicated by the results, was highly influenced by the groove shape [16]. TG-T category had the highest compressive strength and this was attributed to the existence of a stiffening web.…”

“…Therefore, it was assumed that some of the sand would fill into the gaps between joints during compaction. Additionally, Lilley [10,11] also stated that blocks laid on loose sand would have its joints filled up 15 mm to 30 mm during compaction. According to BS 6717 [5], the length of the USCP divided by its effective thickness, he, should not exceed 5.…”

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.

“…Variants of pavement made of concrete paving blocks with a modified geometric shape of the underside surface with pyramidal elements [9] and with a base of trench groove-triangular (TG-ThG) were previously proposed [10]. Experimental studies indicate an improvement in the quality characteristics of such pavements.…”

Improving the reliability and durability of sidewalks, footways, car parks and areas for various purposes, made of concrete paving blocks (CPBs), is an important task of construction. In order to improve the quality characteristics, new pavements consisting of concrete paving blocks with a ribbed underside surface are proposed. Hypotheses about the advantages of the developed structural solutions of pavements relative to traditional pavements of blocks with a flat underside surface were formulated. To confirm the hypotheses, studies of one of the developed pavement variants of in laboratory conditions were performed. The article describes the plan and methodology for implementation two series of experiments. In the first series of the experiment, a section of a traditional pavement of concrete blocks with a flat underside surface was investigated, in the second, a section from a pavement of concrete paving blocks with a ribbed underside surface consisting of three prismatic elements. Qualitative characteristics of the pavement are determined by various indexes. As a result of laboratory tests, the dynamics of settlement of experimental CPBs under the influence of vertically applied load was studied, and density index of a sand structural layer located under the tested CPBs was also obtained. The settlement indexes of the tested CPBs were investigated for three days. A comparative analysis of the experimental results confirmed the hypothesis about the advantages of pavements of concrete paving blocks with a ribbed underside surface. For the further implementation of the developed pavement variant in the construction industry, additional research is required. Further research directions of pavements of concrete paving blocks with a modified geometric shape of the underside surface are determined.
