“…11a, b show that the rate of change of both total and the repeated settlement of the loaded surface decreases as the number of cycles of load increases, and their response became almost stable after the first ten load cycles, especially for the geocell-reinforced sands. Suku et al [20] have also reported a similar trend of observation for both reinforced and unreinforced soils under repeated loading. Figure 11(a) also illustrates that the total settlement (s t ) under repeated loading reduces by 56% with inclusion of geocell reinforcement, which may be due to upsurge in stiffness of the reinforced sand bed compared to the unreinforced sand.…”

“…In spite of its beneficial effects, only a few studies have been conducted to investigate the behaviour of geocell-reinforced soil under repeated loading. Moreover, the studies reported earlier mainly focused on traffic loads or machine foundation loads [14][15][16][17][18][19][20]. However, structures such as petroleum tanks and shipyard have higher live loads, which vary with time, as compared to the self-weight of the structure.…”

This paper describes the behaviour of a square model footing resting on a geocell-reinforced sand bed subjected to static and repeated loads. The static load tests were conducted to investigate the performance improvement of reinforced soil in terms of bearing capacity and settlement. The repeated load tests were carried out with varying initial static pressures to simulate the structures wherein the live loads change slowly and repeatedly such as oil or water storage tanks do. The ultimate bearing capacity, effect of initial static pressure as well as the number of load cycles without and with the use of geocell reinforcement were the main parameters to be investigated in this study. The results showed that with the provision of geocell reinforcement, the bearing capacity of reinforced soil increased by 2.4 times as compared to unreinforced soil, and the settlement decreased by 68% at the measured settlement level, s/B = 10% (s = settlement of footing, B = width of footing). It has also been observed that the total settlement reduces by 56% in case of geocell-reinforced sand after the application of 20 load cycles. Further, the results show that the total settlement increases at a gradually decreasing rate with an increase in initial static pressure and the number of load cycles.

The work was carried out on the village roads where the traffic intensity is very low. The roads should be constructed as durable and with minimum construction cost without affecting the strength. Therefore the experiments were carried out on different types of roads. The experiments can be performed in the laboratory but that is not sufficient and therefore the tests should also be performed on the actual constructed pavement patches. The non destructive test is the best way to check the parameters responsible for the effectiveness of pavement. The non destructive testing machines like ground penetrating radar (GPR) and falling weight deflectometer is used to assess different parameters of pavements. The subgrade moduli is also compared with the help of these machines. The falling weight deflectometer (FWD) was carried out on the plastic cell filled concrete block pavement (PCCBP), Geocell filled concrete concrete block pavement (GCCBP) and grouted macadam (GM). The deflection, modulus of elasticity, strain, thickness calculation, area, RRS were calculated through this test by the back calculation. From this observation it is found that the geocell filled concrete block pavement performed well as compared to the other pavements in terms of the calculated parameter. The deflection was more in the grouted macadam when compared with the PCCBP and GCCBP.
