To solve the problem of rutting and fatigue damage to asphalt pavement, rutting and fatigue performances of Qingchuan rock asphalt modified asphalt were studied, based on the dynamic shear rheometer test, the dynamic creep test, the rutting test, the indirect tensile fatigue test, the small-sized acceleration loading test, the compressive resilient modulus test, the BISAR3.0 Program and the rut...

We investigated the possibility that tendons that normally experience relatively high stresses and function as springs during locomotion, such as digital flexors, might develop different mechanical properties from those that experience only relatively low stresses, such as digital extensors. At birth the digital flexor and extensor tendons of pigs have identical mechanical properties, exhibitin...

This paper discusses the laboratory design of continuously graded asphaltic concrete mixtures containing styrene butadiene styrene (SBS). The purpose of this study is to evaluate mechanical properties of control and SBS modified asphalt mixtures. Furthermore rheological properties of conventional and modified asphalt in different SBS content were studied. AC-10 was used as binder in the study. ...

a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...

this paper is a state-of-the-art in sulphur-asphalt (sa) design technology based on a comprehensive analysis of current practice and technical literature, in order to investigate the possible use of sa pavements in iran. in this paper, the major aspects(material, technology, properties, production, placement, quality assurance, design, and field varification) of sa pavements are considered. fer...

The use of reclaimed asphalt pavement (RAP) to create recycled mixture is attracting great interest because landfill space decrease and natural resources saving. Also, incorporating rejuvenators an effective method promote the utilization RAP materials in hot mix (HMA) production. main goal this study was evaluate effect Cyclogen vacuum bottom (VB) on performance mixtures against moisture sensi...

This research intends to evaluate the effects of waste polyethylene terephthalate (PET), antistripping agents (ASA), and ground tire rubber (GTR) on performance properties stone matrix asphalt (SMA) mix binder/water damage resistance. Liquid agents, added 85/100 penetration grade binder ASA effects, were A (M500), B (EvothermM1), C (LOF-6500). Tests conducted study modified bitumen’s rheologica...

In Pakistan, mostly flexible pavements are constructed which have a higher susceptibility to rutting, moisture damage and stripping. Under current economic conditions, one such solution overcome this is the addition of economical locally available additives in bitumen being produced by our refineries. This study investigates effects bakelite as an additive on various mechanical properties. Bake...
