The design of road structures in Senegal is based on the assumption of linear elastic behavior of the materials making up the various pavement layers. However, studies have shown that the experimental behavior of granular materials is rather nonlinear elastoplastic and is characterized by the reversible modulus M r which depends on the state of stress. In this article, the study of nonlinearity was investigated with a view to its possible consideration in the design of flexible pavement structures. The results showed that the strains and stresses found are higher in the nonlinear case than in the linear case. Compared with the results obtained with the nonlinear model integrated into Alizé LCPC, the k-Ө model tends to overestimate vertical stresses and strains in sub-base layers. For subgrade layers, however, Alizé LCPC seems to overestimate them. These variations could be explained by discontinuities at layer interfaces and variations in the stiffness of materials in the pavement. However, the validation of nonlinear calculations with a view to improving road design in Senegal remains to be verified, in particular by experimental data.

Refraction is always a major problem for the near-ground geodetic measurements. Thus far, there have been numerous studies showing the influences of atmosphere on the refracted ray leading to the variation in the distance and direction measurements. The refraction is projected into two non-correlated components on horizontal and vertical planes called horizontal and vertical refraction, respectively. Both impact the measurements in their corresponding directions. It is noted that, in terms of magnitude, the refracted zenith angle, in vertical plane, has always been assumed to be far larger than refracted horizontal angles (i.e., refracted horizontal angle is imagined to be minor or negligible). There are considerable productive understandings of vertical refraction influencing the vertical/zenith direction in the literatures. However, the limitation in determination of the horizontal (side or lateral) refraction is still a debatable issue. The research aimed to reveal the broader comprehension of the horizontally refracted ray affecting horizontal angle measurements. The presented model embraces the relationship between the zenith angle and refracted horizontal angle, which could be the desirable technique to computation of refracted horizontal angle at each zenith angle (i.e., ideally, it can be employed in the case of terrestrial laser scanning due to the change of zenith angle for every individual measured point). Thus, the dependency between vertical and horizontal refraction will be obvious.
