“…Various types of tests have been performed by researchers on fiber reinforced soils such as triaxial tests, unconfined compression tests, CBR tests, direct shear tests, and tensile and flexural strength tests [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The incorporation of randomly distributed fibers offers the prime advantage of overcoming the weak potential planes which usually develop parallel to the oriented reinforcement [7].…”

This paper presents the experimental results obtained from tests conducted on clayey soil specimen stabilized with pond ash (PA) and cement and reinforced with randomly distributed fibers. The amount of PA and cement were varied from 0-50 and 0-6 % respectively by dry weight of the soil. In order to understand the influence of admixture on the strength properties of clay, compaction tests, unconfined compression tests (UCS), split tensile strength (STS) tests and California bearing ratio tests (CBR) were conducted. In addition scanning electron microscopy and X-ray diffraction tests were carried out on certain samples in order to study the surface morphological characteristics and hydraulic compounds, which were formed. The specimens were tested for their strength behaviour at different curing periods. The obtained results have shown that addition of mixtures leads to a decrease in the maximum dry density and increase in optimum moisture content. The results also indicate that the proposed method is very effective to improve the strength of the clayey soil in terms of UCS, STS and CBR tests.

“…The stabilized layer may also be subjected to tensile stress due to differential ground movement caused by seasonal variations and temperature gradients. The split tensile strength of flowable high volume fly ash cement composite, lightly cemented sand and compacted soil fly ash carbide lime mixtures was reported by [18][19][20]. Generally a recycled construction material should satisfy the requirements of strength [21].…”

“…The numerical simulations make it possible to assess the influence of material parameters on limit bearing pressures, q u2% , the loading required to produce 2% relative settlement. More formal assessment of the influence of each of the material constitutive parameters was carried out with multiple regression analysis (MRA) (Consoli et al 2002). Box and Draper (1987) and Myers and Montgomery (1995) gave more detailed information on MRA and the use of standardized regression coefficients.…”

This work proposes a method for predicting the behavior of shallow footings bearing on an upper layer of processed cemented soil that overlies a lower layer of weakly bonded residual soil with a high void ratio. The paper describes the results of a series of field plate tests and numerical simulations. The results lead to a semi-empirical method for designing shallow foundations on a double-layer system. The method has been validated by comparison of predicted values with results from a separate series of plate-loading tests. For engineering practice, the proposed method provides acceptable predictions of bearing capacities and load-settlement curves.Key words: footings, cemented layer, layered system, weakly bonded, high void ratio.Résumé : Ce travail propose une méthode pour prédire le comportement de semelles superficielles portant sur une couche supérieure de sol-ciment fabriqué qui repose sur une couche inférieure de sol résiduel faiblement cohérent avec un rapport de vides élevé. Cet article décrit les résultats d'une série d'essais de plaque sur le terrain et de simulations numériques. Les résultats conduisent à une méthode semi-empirique pour la conception de fondations superficielles sur un système à double couche. La méthode a été validée en comparant les valeurs prédites avec les résultats d'une série séparée d'essais de chargement de plaques. Pour la pratique de l'Ingénieur, la méthode proposée fournit des prédictions acceptables des capacités portantes et des courbes charge-tassement.
