Web26 sep. 2024 · The mixtures with PG 58-34 binder tended to have lower ITS than those with PG 67-22 binder. It may be because the foamed asphalt using higher PG binder was more viscous and provided more stiffness in the asphalt-RAP bonding. Tensile strength ratio was relatively consistent above 0.8 except for two mixes. WebThe tensile strength is calculated using the following equation: English units: St = 2P π t D where: St = tensile strength, psi P = maximum load, lbs t = specimen thickness, in. D = …
Moisture damage is the result of moisture interaction with the asphalt binder-aggregate adhesion within a HMA mixture. This interaction can cause a reduction of adhesion between the asphalt binder and aggregate … Meer weergeven The following description is a brief summary of the test. It is not a complete procedure and should not be used to perform the test. The complete test procedure … Meer weergeven Webthe air–void ratio increases after fatigue damage at different test temperatures. Therefore, the rising temperature is harmful to the fatigue performance over low temperature range from -10°C to 10°C. As has been seen, the indirect tensile strength test is the primary test carried out to characterize the stiffness of a bituminous mixture.
WebThe purpose of this paper is to present a simple method for evaluating the rut resistance of asphalt concrete mixtures using indirect tensile (IDT) strength alone or in combination with unconfined compressive strength. Research has shown surprisingly strong correlations between these test data and the rut resistance of asphalt concrete mixtures as observed … Webtensile strength ratio as well as the size of the specimen. ...
