“…However, Miura et al [14] found that pavement performance was influenced more by the block shape and laying pattern than the block thickness by using rutting depth as an indicator. 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].…”

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.

“…The FEM is a kind of approximate calculation method, the essence of this method is to segment a solid continuum split into several finite discrete units, and combine into the collective. In each unit, assuming the displacement field and stress field, apply the variation principle to establish edalgebraic equations, and using the generalized displacement node or generalized stress to solve the unknown quantity [4,5]. This passage applies FEM to analyze the hexagon cement block.…”

The growth rates of stress in the hexagon , square and octagon cement blocks under different vehicle loads were analyzed using the finite element method (FEM). The growth rate of bottom layer stress of the hexagon is the smallest among them when vehicle loads increase. Under the 400kN loads, the growth rate of bottom layer stress of the hexagon significantly reduced as the thickness increase. When its thickness is up to 28cm,the bottom layer stress is the smallest among the three kinds of shapes. The results show that the hexagon cement block is the most suitable for overload vehicles obviously when compared to the square and octagon cement block. Therefore, hexagon cement block is the most suitable for the roads which are always under heavy and overload vehicles .

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.
