In this work, cohesion-less asphalt geo-material supported with multi-facets of geo-support as jute filaments have been contemplated. The current work is completed on the unreinforced soil and jute fiber supported soil to research the strength and firmness limit of asphalt geo-materials utilizing California bearing ratio (CBR) test. The quantity of layers, ideal profundity and arrangement of the geo-support in geo-material are researched. The implant profundity of jute fiber, i.e., D/2, D/3 and D/4 in single, twofold, and significantly increase layers has been upgraded utilizing CBR values. A clever idea of firmness limit alongside entrance factor is acquainted with assess the strength of the unreinforced and jute-supported geo-material. The experimental outcomes exhibit that remembering jute fiber for single, twofold and triple layer builds the solidness limit of the dirt at the ideal profundity of D/4. The liquid limit at shifted input boundary fluctuates from 0.378 to 0.682 at most extreme entrance factor which shown an 80.42 % upgrade of solidarity in asphalt geo-material. The result of the current review gives a savvy answer for the strength improvement in cohesion-less soils for dike, subgrade, and asphalt development advances.

“…The piezocone penetration test (CPTU) has gained popularity for site investigations due to its cost-effective, rapid, continuous, and reliable measurements [1,2]. From CPTU results, the soil profile, undrained shear strength, in situ hydraulic conductivity, overconsolidation ratio and constrained modulus can be estimated [3,4].…”

Studies of the effect of clay structure on piezocone penetration test (CPTU) results are beneficial for interpreting CPTU data in naturally or artificially cemented structured clays. The structured Cam clay (SCC) model was implemented into Abaqus, and the validity of the user-defined material (UMAT) subroutine of SCC was verified by predicting the experimental data for the laboratory oedometer test and drained and undrained triaxial shear tests of structured clays. A numerical model of piezocone penetration into structured clay was established, and numerical simulations showed that, compared with those for unstructured clay, the values of the mean effective stress near the cone tip were smaller, and the values of the excess pore water pressure (u) were larger for structured clay due to the additional destruction-associated plastic volumetric strain. The maximum deviator stress did not appear near the cone tip but appeared at a certain distance below and to the right of the cone tip, which manifested the strain softening characteristic of structured clays. The cone resistance (q c ) values increased linearly with increasing structural strength (S σ ). The larger the value of S σ was, the higher the value of u, but S σ did not influence the patterns in dissipation curves of u. The value of the empirical cone factor (N kt ) decreased with increasing S σ , since the clay structure caused a smaller increase in q c than in the undrained shear strength, and a formula for estimating the N kt of structured clays was proposed. Compared with those for overconsolidated clay, the values of mean effective stress and deviator stress around the cone tip were smaller for the structured clay due to structural damage occurring at large strain, which resulted in a smaller value of q c , and the "nonstandard" dissipation phenomenon was less pronounced for the structured clay due to the shear-induced relatively large positive u.
