Abstract: Expansive subgrade soil possesses a dual nature of swelling and shrinkage, resulting in a premature failure on pavement surfaces. In the present investigation, an effort has been made to compare the field performance of ...

Abstract: This study emphasized binder aging of bituminous mixtures in the field and compared it with newly developed field-simulating laboratory aging procedures. Monthly field cores from a pavement section were collected for this ...

Abstract: Stone matrix asphalt (SMA) is a highly rut-resistant gap-graded asphalt mixture. The inclusion of supplementary materials such as fiber, filler, and polymer-modified bitumen (PMB) makes the layer more expensive to construct. ...

Abstract: Open-graded friction course (OGFC), which consists of an open gradation mostly of coarse size aggregate with little fines, is a special purpose mixture that is increasingly used in pavement surfacing around the world. The ...
