Effects of Aggregate Gradation on Resilient Modulus and CBR in Unbound Granular Materials
Resilient modulus and California Bearing Ratio (CBR) in unbound granular materials are the key technical characteristics of layers in a flexible pavement design. Among the factors affecting these two parameters, the aggregate gradation is the most important. Using particle size distribution curve developed by AASHTO, together with other considerations mentioned in the related regulations have y...
متن کاملNumerical simulation of granular materials behaviour for unbound base layers used in Algerian pavement structures
Structural analysis of flexible pavements has been and still is currently performed using a multi-layer elastic theory. However, for thinly surfaced pavements subjected to light to medium volumes of traffic, the importance of non-linear stress-strain behaviour of unbound granular materials (UGM’s) requires the use of more sophisticated numerical models for structural design and analysis of such...
متن کاملShakedown of unbound granular material
Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading. A particularly interesting question is whether a...

متن کاملModular ratios for unbound granular pavement layers
Unbound granular pavement layers show a characteristic increase in moduli from the subgrade to the surface. The ratio of moduli between successive layers provides a direct and effective measure of pavement quality that makes due allowance for site conditions and seasonal effects beyond a contractor’s control. The modular ratio is therefore an effective indicator for performance-based specificat...
