Ground tires are one of the main sources urban solid waste. Rubber powder-modified asphalt provides an effective method to solve problem, and it presents good high- low-temperature performance in sustainable pavement construction. However, storage properties rubber asphalts prepared from traditional shear mixing unstable, which restricts their application. In this study, four test methods (the ...

In this paper, we present the results of dispersion thermodynamically immiscible polypropylene (PP) and ethylene-propylene triple synthetic rubber (EPTSR) polymer blends using Solution-Enhanced Dispersion by Supercritical Fluid (SEDS) technique at operation conditions in pressure range (8 to 25) MPa temperatures t = 40 °C 60 °C. The kinetics crystallization phase transformation obtained convent...

The objective of this study was to evaluate the opinions and attitudes of dentists toward the use of rubber dam during various restorative procedures in their dental practices. A structured questionnaire was designed, and distributed to 300 dentists and those that were fully completed were collected for analysis. The collected informations about the opinions and attitudes of dentists toward the...

Consecutive extraction of latex and natural rubber from the roots of rubber-bearing plants such as Taraxacum kok-saghyz (TKS), Scorzonera tau-saghyz (STS), and Scorzonera Uzbekistanica (SU) were carried out. Latex extraction was carried via two methods: Blender method and Flow method. The results of latex extraction were compared. Cultivated rubber-bearing plants contained slightly higher latex...

To improve the blast resistance of a wall system, it is necessary to enhance its energy absorption capabilities and/or increase its mass. Much research has been performed on improving the ductility, and thus the resistance, of a wall system using elastic materials externally attached to the tension side of a wall. This project investigated the static resistance of wall systems with elastic mate...

In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves ...

This study investigates basin-scale hydrologic implications of the replacement of forest-dominated land cover by rubber plantations in Montane Mainland Southeast Asia. The paper presents a new method for estimating the water demand of rubber and consequently water losses to the atmosphere through rubber evapotranspiration (ET). In this paper we argue that rubber ET is energy-limited during the ...
