NEW METHOD OF SIMULATING LAYERED SYSTEMS OF UNBOUND GRANULAR MATERIAL

The stress-strain analysis of multilayered pavements is becoming more precise--commencing with elastic solutions and developing through the more complex finite element analysis. The mechanolattice has been reasonably successful in predicting pavement performance because it takes relative plastic behavior into account. Recently, an option was developed that enables the mechanolattice to simulate any unbound granular layers in pavement. The principles of operation of the unbound simulation are described and its effects demonstrated using Sections 2 and 9 of the Pennsylvania State Test Track. The effects predicted with the "all bound" assumption are contrasted with those in which unbound layers are simulated as unbound. It is pointed out that the differences are functions of modulus ratios and the magnitude of relative plastic behavior. Many of the effects are not dependent on the absence of creep or relaxation.
