Recently, scrap tire rubber-modified asphalt binders and pavements have been the preferred choice of state DOTs parties involved due to desirable engineering, as well economic environmental impacts. Rheological mechanical properties rubber modifications main focus researchers for last couple decades. This paper investigates rutting potential, fatigue cracking resistance, continuous performance ...

Significance Magnetic soft continuum robots (MSCRs) capable of magnetic field–controllable steering offer great promise for the endovascular treatment cardiovascular diseases. However, existing MSCRs are often limited to small workspaces because lack efficient design and optimization tools. In this work, we introduce an evolutionary strategy by integrating theoretical modeling genetic algorithm...

In this study, halloysite and sepiolite nanoclays were used to reinforce SBS modified bitumens. The are different from the materials in literature have properties such as easy find, economical available local sources. mixing parameters determined before production process. polymer additive was added into base bitumen at 3% 5%, nanoclay additives 2% 4% ratios. morphological structures investigat...

High content SBS polymer modified asphalt (HCPMA) can serve as pavements under heavy traffic and a wide range of temperatures. However, the applicability validity standard rheological evaluation methods to characterize HCPMA are still unclear. In this study, influence on conventional properties behavior was analyzed. A higher improve performance grade binder PG100-34. The slope Jnr-σ linear cur...

The complete genome of methanol-utilizing Amycolatopsis methanolica strain 239T was generated, revealing a single 7,237,391 nucleotide circular chromosome with 7074 annotated protein-coding sequences (CDSs). Comparative analyses against the complete genome sequences of Amycolatopsis japonica strain MG417-CF17T, Amycolatopsis mediterranei strain U32 and Amycolatopsis orientalis strain HCCB10007 ...

Abstract The polyurea elastomer (PUA) powder modifier was prepared by the method of spraying–initial crushing–fine grinding, and then, PUA-modified asphalt produced. typical functional structure PUA identified characterized. apparent viscosity tested at different temperatures. impact particle size content on creep recovery properties high temperature investigated through multiple stress test. m...

To analyze the effect of polyol on polyurethane (PU)-modified asphalt, three different soft segments were synthesized, and we utilized reaction MDI (diphenylmethane diisocyanate) with PU650, PU1000, PU1400. With respect to molecular weight, performance modified asphalt was analyzed, by using polyurethanes. PU samples, Fourier transform infrared spectroscopy (FTIR) tests gel permeation chromatog...

This paper conveys the laboratory investigation of storage stability CRM binder as a basic study. The was produced through wet process in laboratory. percentages crumb rubber used for rubberized were 5%, 10%, 15% and 20%. samples prepared according to ASTM D7173. In order evaluate properties each part binders, tests carried out rotational viscosity viscoelasticity, separation index assessed wit...
