CONTROL OF DESIGN OF PAVEMENTS THROUGH ELASTIC LAYERS METHOD USING REAL DYNAMIC MODULES VALUES

The paper describes the first experiences made in Argentina properties of road materials and the use of actual modulus values so determined to the control of flexible pavements through Elastic Layers Method. The first part of the paper describes the technique and Instrumentation developed to make in situ measurements of elastic properties of the different layers by the Surface Wave Method and laboratory test on cores by non-destructive Resonance and Pulse methods. The second part of the paper refers to the control of several flexible pavement designs by Elastic Layers Method using real dynamic modulus values obtained by the Surface Wave Method. The flat terrain of Santa Fe, the unfavorable soil profile and the lack of coarse granular materials in the zone, makes a difficult situation for an economical pavement design. The used procedure has permitted to clarify the properties of very peculiar structures of pavements as "Sand-Soil asphalt Emulsion Stabilization" which was quite a pioneer process to make stable Sub-Base and Base layers with fine local materials. /Author/
