  • What is Asphalt Concrete? (with pictures)

    26/05/2020· Asphalt concrete, commonly called asphalt, tarmac, pavement or black top, is a composite material used in the construction of roadways and parking lots. This composite is a mixture of a petroleum byproduct, asphaltic bitumen and aggregate materials.

  • Differences Between Concrete and Asphalt Pavement

    The flexible pavement is an asphalt pavement. It generally consists of a relatively thin wearing surface of asphalt built over a base course and subbase course. Base and subbase courses are usually gravel or stone. These layers rest upon a compacted subgrade (compacted soil). In contrast, rigid pavements are made up of portland cement concrete and may or may not have a base course between theОнлайн-запрос
