More frequent worldwide use of asphalt-rubber binders in road building has increased the need for rotational viscotesters, which are used to ensure proper quality control and assurance. While an appropriate standard for viscotesters does not currently exist, a proposed new ASTM standard will answer this need. The proposed standard, WK25108 , Test Method for Measurement of Apparent Viscosity of…

Test for Solubility of Asphalt Materials in n-Propyl Bromide A new ASTM International standard on solubility of asphalt will provide an alternative for a solvent that has been banned as an ozone depleter by the Kyoto Protocol, an international environmental treaty with the goal of stabilizing greenhouse gas concentrations that may help minimize global warming. The new standard, ASTM D7553 , Test…
