Surface Modification of Steel Slag Aggregate for Engineering Application in Asphalt Mixture

The proper disposal of steel slag has always been a great challenge for the metallurgical industry in China and around the world. In this work, the steel slag aggregate (SSA) was surface pretreated (PSSA) and applied into asphalt mixture. The adhesive behavior between the bitumen and five different types of aggregates (i.e., limestone, diorite,...

Adhesion of aggregate-binder systems

Adhesion is a difficult, but important phenomenon which needs to be addressed in the field of pavement engineering. A strong adhesion between the constituents of pavement and between the layers of the pavement is an indication of its durability. Many modern materials like rubber, fibre, epoxy binder, adhesion promoter etc., are used as a...
