An Update on Performance Grade Binder Implementation Welcome to our first event 0f 2022. We all know why the Performance Grade Binder specification came into being in 2016. The adoption of a specification framework for bituminous binders based on engineering properties helps the industry to ensure optimal performance of flexible pavements, especially in the higher

Over the past 3 decades the use thereof has extended to southern Africa, including Namibia where
read moreAbstract EME are used for pavements which require a high stiffness modulus, high resistance to rutting, good fatigue resistance and good durability. This technical solution has been already used with great success in South Africa and more projects are currently being developed. But EME quality is also dependent on its key components. One of the

read moreAbstract Plastic strain causes non-recoverable, permanent deformation in pavement layers. The effect of plastic strain is generally referred to as rutting. Rutting may occur throughout the pavement structure in granular, stabilised and asphalt layers. Granular materials exhibit plastic deformation when loading occurs outside the elastic limits. The fatigue life evaluation of granular layers during design

As a people we have understood for example that we have to be more respectful to our surroundings, to become more environmentally aware, be less wasteful. And well, if
