Evaluation of Binding Properties of Bituminous Pavement Layers
Interlayer bonding in modern multi-layer pavement systems plays a key role in achieving long-term performance of flexible pavements. Poor bonding between bituminous pavement layers has been observed to contribute to major pavement failures such as premature fatigue, top-down cracks, potholes and surface spalling. One of the most common stresses due to poor bonding between bituminous layers is slip failure, which typically occurs when a heavy vehicle accelerates, decelerates, or turns frequently. An adhesive layer is sprayed between the bitumen road layers to improve the adhesion between the layers. A bond coat is the application of a bitumen emulsion or bitumen binder between an existing bitumen/concrete surface and a newly constructed bitumen overlay. Hot bitumen binder, cut bitumen, or bitumen emulsion are commonly used as adhesives. The purpose of this study is to evaluate the adhesive strength at the interface between pavement layers by conducting laboratory tests. To achieve this goal, we used it on a Marshall load frame to evaluate the performance of a bond coat applied to the interface between layers of bituminous concrete (BC) and dense bituminous macadam (DBM) in the laboratory. Three specific attachments are manufactured for In this study, 100 mm and 150 mm diameter samples were applied from 0.20 kg/m2 to 0.25 kg using two commonly used emulsions, CMS-2 and CRS-1, as bond coats. Results were obtained for samples prepared in volume. /m2 and 0.30 kg/m2 are produced at a temperature of 250 °C.
