Physical and Mechanical Characteristics of Soil Within the Culvert Pipes Location of Roads

Abstract

The physical and mechanical characteristics of roadbed soil within the sections of one of the roads of Novosibirsk conglomeration in the culvert pipes locations were studied and analyzed in order to identify their impact on the pavement performance. The engineering and geological elements have been identified, for which correlation-regression analysis of the soils physical and mechanical characteristics were performed and their statistical parameters were determined. It has been established that there is pavement surfacing unevenness in 93% of cases, the root cause of which is the presence of loosen areas of the roadway. It is noticed that the soil physical and mechanical characteristics improve with a distance from the culvert pipes. The stages for assessment of soil physical and mechanical characteristics are proposed based on a sample experimental determination of the deformation modulus for typical engineering and geological elements by means of calculation of the main characteristics according to the correlation-regression equations, and designing the reconstructive measures.
