Question

Compared to asphalt, portiand cement concrete is characterized by higher contents and better interlocking of the aggregates O True O False Save Question 18 (2 points) Asphalt concretes are particulate composite materials which consist of a continuous binder phase and about 95% of discontinuous particulate (aggregates) phase. True False Save Question 19 (2 points) Hirsch's model which is a combination of the parallel and series modets can be used to describe the behavior of particulate composite materials True O False Save
