Structural Behavior of Cast In Situ Concrete Block Pavement

Structural assessment of plastic cell-filled concrete block pavement (PCCBP): an experimental study

“…It can be seen that there is no significant variation in sub-base elastic modulus (, 90 MPa) for all the different thicknesses considered. The result obtained is in good agreement with that obtained by Ryntathiang et al (2005), this may be related to similar thicknesses of WBM (, 100 mm) considered. On the other hand, Roy et al…”

“…The higher elastic moduli values of Roy et al (2009) may be related to the lower deflections as presented in Section 5.1. In the case of Ryntathiang et al (2005), the deflection is higher than that of this study and correspondingly the elastic moduli are also lower than those of this study. The variations in sub-base and sub-grade elastic moduli with PCCBP thickness are shown in Figures 19 and 20, respectively.…”

“…Roy et al (2009) and Ryntathiang et al (2005), is presented in Figure 15. It can be seen that this study showed higher peak deflection than obtained by Roy et al (2009) and almost agrees with that obtained by Ryntathiang et al (2005).…”

“…Roy et al (2009) and Ryntathiang et al (2005), is presented in Figure 15. It can be seen that this study showed higher peak deflection than obtained by Roy et al (2009) and almost agrees with that obtained by Ryntathiang et al (2005). The lower value of deflection obtained by Roy et al (2009) Zone II of IS 383 (1970) and with a higher soaked CBR of , 8%] in a brick wall confined pit of size 3 £ 2 m, which may have resulted in lower deflection.…”

“…In India, studies of this PCCBP technology have been reported by Ryntathiang et al (2005), Pandey (2006), Sahoo et al (2006) and Roy et al (2009) on the costeffectiveness and feasibility of rural roads. Albeit their studies were confined to selected (, 100 mm) PCCBP thicknesses, it was observed that PCCBP can provide sufficiently high elastic modulus with low initial and maintenance cost.…”
