Characterization of oxidative aging in asphalt concrete pavements

Asphalt concrete mixtures with different levels of oxidative aging, prepared by oven-aging the mixture at 135 oC for different amounts of time, were used to study the effects of oxidative aging upon the ultrasonic phase velocities and attenuation measurements. It was a observed that both the dilatational

Oxidative age hardening of bitumen results in increasing fatigue susceptibility of bituminous mixtures, thus reducing the service life of asphalt pavements. Polymer additives to bitumen have been shown to improve its viscoelastic properties and, in some cases, reduce the level of bitumen hardening.

Concrete Operational Stage of Cognitive Development Explained

The concrete operational stage is the third stage in Piaget's theory of cognitive development. This period spans the time of middle childhood—it begins around age 7 and continues until approximately age 11—and is characterized by the development of logical thought. 1. Thinking still tends to be very concrete, but children become much more
