“…As shown in Figure 13, the difference in rut depth depending on block shape was insignificant; rut depth was found to be affected more by the construction pattern than by block shape. These findings are similar to those from a field test [16]. It is inconclusive, however, that construction pattern is the only determinant in load distribution effect.…”

“…In order to avoid the loss of bedding sand, a geotextile was placed between the base and bedding sand. Three construction patterns considered in most of the CBP design guide (ASCE 2015) [7,21] were assessed: stretcher, basket weave, and herringbone bond, which were the same test variables in Mampearachchi and Senadeera's study [16]. The blocks used in this test were 200 mm × 100 mm × 80 mm rectangular blocks.…”

“…Based on the analysis results of finite-element model, Mampearachchi and Gunarathna [15] pointed that the performance of CBP was found to be affected more by the construction pattern. Then the viewpoint was demonstrated by the deflection basins data measured in the field test [16]. Variation of deflection among different laying patterns was significantly high compared with deflection variations of block shapes.…”

Concrete block pavement (CBP) is distinct from typical concrete or asphalt pavements. It is built by using individual blocks with unique construction patterns forming a discrete surface layer to bear traffic loadings. The surface structure of CBP varies depending on the block shapes and construction patterns, so it is hard to apply a general equivalent elastic modulus estimation method to define the surface structural strength. In this study, FEM analysis and dynamic loading test were carried out to develop a deflection prediction model for CBP considering the block shapes and construction patterns. Based on the analysis results, it was found that block shapes did not have much effect on load distribution, whereas construction patterns did. By applying the deflection prediction model to the rutting model for CBP proposed by Sun, the herringbone bond pattern showed the best performance comparing with stretcher bond or basket weave bond pattern. As the load repetition increased to 1.2 million, the rutting depth of CBP constructed by herringbone bond pattern was 2 mm smaller than those constructed by the other two patterns.

Paving stones are increasing, being used by corporate bodies and individual for its functionalities and aesthetic value, the production of pavers over the years have been specifically carried out using stone dust which is relatively expensive and not readily affordable to the common man. This study was carried out to determine comparative effect of grinded and un-grinded palm kernel shell on the strength of pavers. Stone dust, river sand, grinded palm kernel shell, un-grinded palm kernel shell and cement were combine in different ratio namely,T1(4,0,0,0,l), T2(0,2,2,0,l), T3 (1,2,0,1,1), T4(1,1,2,0,l), T5(1,1,0,2,l), T6(0,2,l ,l,1) respectively to form six treatment with two replicates. The pavers were tested for weight and strength properties, T3 has the highest value of the mean weight while T1 has the lowest value. T3 (stone dust (1),river sand (2), un-grinded palm kernel shell (1) and 25kg of cement (1)), T1(stone dust (4) and 25kg of cement (1)).Also, the compressive strength results show that T3 also has the highest value of 127Mpa(Mega pascal) whileT6 has the lowest value of 33Mpa (Mega pascal). The data collected was subjected to analysis of variance (ANOVA) to determine the difference in the strength of the pavers. The analysis of variance shows that there is no significant difference between the compressive strength of the treatments. The colour of the paver shows that the paver produced with river sand and un-grinded palm kernel shell is brighter and stronger than others, it is then recommended that T3 can be used in the production of pavers because it is strong and can also withstand environmental stress.

“…According to the previous literature, a homogeneous, well-filled joint 2-3 mm wide is required to achieve the optimal load distribution [13]. The rotation of the block due to an external load causes "arching thrust" and provides a high load-bearing capacity through additional rotation suppression of the constraint conditions [14].…”

Performance Evaluation of Bedding Sand and Load Transfer Characteristic of Concrete Block Pavements

Concrete block pavement is used as a modern pavement type owing to its economic benefits. The physical properties, mechanical properties, and functional characteristics of bedding sand and joint sand, the main components of concrete block pavements, should be accurately understood. Owing to the discontinuous structure of these pavements, load transfer efficiency (LTE) is the most important index from the perspective of performance. The factors that affect LTE are bedding sand (type, grading, and thickness), joint sand (type and grading), and concrete block (shape and pattern). Therefore, the optimal design for concrete block pavements can be achieved by analyzing each factor. In this study, three types of sand (river, quartz, and manufactured) were selected to examine the mechanical properties via direct transfer experiments. It was observed that the shear strength of river sand was the highest. It was also found that the difference between the shear strength and the internal friction angle (according to the content of 0.6 mm in the grading of bedding sand) was not large, and the shear strength and the friction angle increased as the content increased to 0.075 mm. In addition, the load transfer characteristics of the joint and rotational interlocking of the block were evaluated through a non-destructive test using the degree of joint filling, block shape, and construction pattern as variables. As a result, the degree of joint filling had the greatest effect on the load transfer characteristics of the joint and rotational interlocking of the block. The effect of the block shape was larger than that of the construction pattern. When a heavy load is applied, the LTE between blocks must be maintained at 50% or more, and the rotation of blocks at 0.6° or less, if 75% or more of the joint must be filled for preventing excessive vertical deformation.
