TESTING THE UNBOUND LAYERS OF PAVEMENTS FROM RECYCLED ASPHALT MIXTURES.

The asphalt pavement materials which are after the Life cycle can be used in the production of new asphalt mixtures. If its quality of material is not suitable for the production of asphalt mixtures (inhomogeneity of material, soil content, etc.), the material can be used in unbound layers of pavements. The Road materials (new or recycled) are exposed during the operation to the effects of traffic loads and climatic influences, in particular changes in air and humidity temperatures, which are reflected by cyclical changes in pavement and subsoil. Strain of material and substance are generally characterized by deformation characteristics that are an important input for the calculation of stresses and deformation of the pavement construction. The deformation characteristics of un-stabilized course road materials, which are usually protective or underlying layers of the gravel (graded aggregate) or other uncontaminated materials is crucial affected by the load subgrade of the pavements . This contribution deals with the interpretation of the results of the static load test of used in unbound layers of pavements from recycled asphalt mixtures. [ABSTRACT FROM AUTHOR]
