Interlayers in asphalt pavements are potential structural damage initiators. In order to better understand the quantitative role of interlayer parameters, such as surface roughness, binder type, content and loading type on shear strength, this paper focuses effects particle interlock contact conditions strength through experimental numerical modelling. Experimentally, box tests a model material...

Abstract
 
 Bonding conditions between layers that are not ideal in a pavement structure will produce optimal performance, because the does behave as monolithic structure. The use of tack coat is very important to support ability road pavement, thereby improving performance. This study was conducted analyze shear strength at interface AC-WC layer and AC-BC due rubber tire powder varia...

Compared to typical asphalt mixtures, poroelastic mixtures are characterised by high porosity and flexibility, which desirable for traffic noise reduction. However, the same properties increase risk of debonding from lower layer, is a significant source premature damage. The study investigates factors – tack coat agent, type texture layer have greatest impact on interlayer bonding quality. From...

Asphalt concrete pavement is gradually being adopted in cement repair and paving due to its short construction period low vibration aircraft. However, the performance of interlayer binder critical factor affecting effect. For preparation high-performance emulsified asphalt suitable for airport pavement, type dosage modifier emulsifier were taken as factors levels orthogonal test. Combined with ...

The syntheses, structures, and characterization of four 3d-4f butterfly clusters are described. With different polyhydroxy Schiff-base ligands 2-(((2-hydroxy-3-methoxyphenyl)methylene)amino)-2-(hydroxymethyl)-1,3-propanediol (H4L1) and 2-(2,3-dihydroxpropyliminomethyl)-6-methoxyphenol (H3L2), three heterotetranuclear NiLn complexes (NiDy-L1 (1), NiTb-L2 (2), NiDy-L2 (3)) and one heterohexanucle...

The performance and lifetime of the flexible asphalt pavement are mainly dependent on interfacial bond strength between layer courses. To enhance layers, adhesive materials, such as tack coats, used. coat itself is a bituminous material, which applied an existing relatively non-absorbent surface to ensure strong old newly paved layer. primary objective this study was evaluate effects various ty...

BACKGROUND Guided bone regeneration (GBR) is an established and predictable procedure used to obtain adequate alveolar bone for the placement of dental implants. Anatomical challenges, such as the proximity of the maxillary sinus, may lead to complications during a GBR procedure. The purpose of this report is to present a unique and hitherto unreported complication of a GBR procedure, i.e., the...

The repair of incisional and ventral hernias by the laparoscopic method is finding its place in the general surgical field. The use of tacks and transfascial sutures is commonplace. A new hernia has been identified. Two hernias have been seen following the successful repair of incisional hernias. These did not appear to be recurrent hernias as definite findings of fascial defects were present r...
