Abstract Construction and demolition wastes (CDW) are a concern in urban areas, addition, it is well understood that soft soils inappropriate for paving designs. Therefore, this paper presents an alternative solution combining CDW silty soil, aiming to overcome the soil drawbacks by repeated loadings. For purpose, laboratory study was developed, comprising both resilient modulus (M R ) unconfin...

از آن جهت که مواد کامپوزیتی به خصوص کامپوزیت‌ها با زمینه پلیمری ساختارهای آسیب‌پذیری نسبت به صدمات ایجاد شده در فرم ترک و شکستگی هستند. در سال‌های اخیر تلاش‌های علمی جدید در جهت ایجاد یک واحد کنترل داخلی صورت گرفته است، تا بتواند به صورت خودمختار در ترمیم کامپوزیت‌ها عمل کند. نام این نظریه خودترمیمی است. نظریه خودترمیمی ناشی از همسان‌سازی بیولوژییکی، نشان می‌دهد؛ همان‌گونه که عمیق‌ترین زخم‌ها و...

The use of slate waste can help to reduce the impacts caused environment due decrease appropriate disposal areas and disordered consumption raw material. This article presents an analysis Resilient Modulus (RM) California Bearing Ratio (CBR) this in mixtures with clayey soil. To analyze variations RM CBR increase content, tests were carried out on reference (REF) containing (SLT). for granular ...

The unbound granule material (UGM) is widely applied as the base/subbase layer in pavement engineering. poor quality of UGMs mainly result differential settlement and fatigue failure UGMs. This paper presents a laboratory investigation on influence maximum particle size (MPS) aggregates resilient modulus (MR) repeated load triaxial tests were performed under different stress levels. Three nonli...

Purpose: This study aimed to analyze the fracture resistance of denture base resins relined with either a conventional rigid resin or a new resilient resin. Materials and Methods: Two types of test plates were fabricated by relining the base resin (Acron) with a conventional rigid resin (Tokuso Rebase, TR) or a newly developed relining resin (Tokuyama Rebase II, RII). The specimens were divided...

This paper uses the kinematic mapping into the image space of spherical displacements to design a cooperating spherical robot system for workpiece orientating. The kinematic chain formed b y the cooperating robots grasping the workpiece forms a multi degree of freedom closed chain which is also known as a robotic mechanism. The spherical robots considered are spherical RPR open chains and they ...
