BACKGROUND The aim of the present work was to investigate the relative importance of socio-demographic and physical health status factors for subjective functioning, as well as to examine the role of social support. METHODS A cross-sectional health survey was carried out in a Greek municipality. 1356 adults of the general population were included in the study. Personal interviews were conduct...

Incorporating fibers into asphalt mixtures as additives and stabilizers can significantly enhance the performance of pavements. This study aimed to analyze impact using basalt bamboo modifiers on properties mastics. The effects different types rutting resistance, fatigue elastic recovery, low-temperature cracking were tested frequency scanning, linear amplitude scanning (LAS), multiple stress c...

Rubberized asphaltic materials have been frequently combined with warm-mix asphalt technologies to tackle the issues of high energy consumptions and emissions during construction. Effective accurate characterization binder properties is conducive improvement long-term pavement performance. The current study aims quantify effects rubber content additives on rutting thermal cracking performance c...

The chemical–physical hybrid cross-linked double network gel poly (acrylamide-co-acrylic acid)/Sodium alginate/Fe3+ (P(AM-co-AA)/SA/Fe3+, simplified as P-gel) was synthesised by free radical polymerisation combined with hydrogen bonding and ion coordination, which in turn compounded styrene–butadiene-styrene (SBS) to prepare P-gel gel/SBS modified asphalt. FT-IR, UV, XRD SEM analyses confirmed ...

one of the most practical routine tests for convergence of a positive series makes use of the ratio test. if this test fails, we can use rabbe's test. when rabbe's test fails the next sharper criteria which may sometimes be used is the bertrand's test. if this test fails, we can use a generalization of bertrand's test and such tests can be continued innitely. for simplicity...
