Abstract

The strength and durability of road pavement structures are directly influenced by the way in which asphalt layers are bonded. An insufficient bond between pavement layers leads to wearing, tearing, pavement deterioration, and cracking, and the pavement life span is reduced. The quality of bond between pavement layers was determined by direct shear test, using the so called Leutner method, without normal stress in specimen. Test samples were taken at various locations along the Lithuanian road network, from pavements characterized by standard asphalt structure, and reinforced asphalt structure in which geosynthetic materials are used in interlayers.
