What’s the Difference Between Asphalt and

2017-7-18  Between the two, asphalt pavement is the flexible variety. Essentially, asphalt consists of a fairly thin wearing surface built over base and subbase courses. These courses are usually stone or gravel, and they rest upon compacted subgrade (which is compacted soil). Conversely, rigid pavements are constructed with Portland cement concrete.
