Abstract: This paper presents the outcomes of an experimental investigation which focused on the fatigue behavior of bituminous binder for paving applications prepared by combining a single reference neat bitumen with different types of crumb rubber products derived from the processing of end-of-life tires. In the laboratory preparation of the blends, crumb rubber dosage was conveniently limited in order to obtain binders characterized by viscosity values compatible with standard operating conditions normally adopted in the production and compaction of bituminous mixtures. Results obtained from time sweep tests carried out in equi-stiffness conditions showed that fatigue performance is enhanced by the use of the considered crumb rubber modifiers with a dosage-dependent improvement of both fatigue life and crack propagation amplitude. Given that the considered crumb rubber products were quite similar, no significant effects were associated to changes of crumb rubber type.

Abstract: The main target of this research work is to show the differences of the National Structural Codes of the Philippines (NSCP) Seismic provisions of the 2 codes-- NSCP 1992 and the new one, NSCP 2010. In order to work out for the main differences of the Design Base Shear (V), the Linear Static Analysis (LSA), which is considered as the Static Lateral Force Procedure and the Response Spectrum Analysis (RSA), another method specified in the NSCP codes under the Dynamic Lateral Force Procedure were carried out to analyze a Three Storey Reinforced Concrete Public School Building. In the Dynamic Analysis, the maximum ground motion intensity, such as the peak ground acceleration (Amax) of the earthquake is considered. The outcome of this research work is an indispensable tool for Structural Designers who will assess the seismic hazard of existing buildings designed under the NSCP 1992 in terms of their structural integrity. While the structural designers’ liability is not limited to design flaw
