Bituminous Road Construction Steps and Procedure : 1. Bituminous Penetration Macadam Road : In this type of bituminous road the aggregates are bound together by grouting bitumen into the voids of the compacted aggregates. This type of bituminous road is generally adopted for the thickness of 50 and 75 mm.
What is The Paving Process? Asphalt paving means paving road surface with asphalt aggregate. Asphalt provides quite, smooth, resilient surface and is one of the most versatile pavement materials used in modern construction. Its Pavement structures are designed to handle any load from passenger cars to heavy lorry.
Figure 6: Standard bituminous patch in porous asphalt parking lot. This lot was constructed with an unmodified porous mix (i.e. no polymer modification) and had rutted in the center of the aisle due to construction traffic. 5
The layer between Asphalt Base Course (ABC) and Asphalt Wearing Course (AWC) is called Tack Coat. Tack Coat is also applied between the concrete deck slab of bridges and AWC laid over it, or concrete slab of Rigid Pavement on which AWC is to be laid. The purpose of Tack Coat is to form a bond between AWC and ABC (or concrete slab).

Note paragraph 3.1 from the standard reads: 3.1 Samples obtained in accordance with the procedure given in this practice may be used to measure pavement thickness, density, resilient or dynamic modulus, tensile strength, Marshall or Hveem stability, or for extraction testing, to determine asphalt content, asphalt properties and mix gradation.
8. Choose an asphalt size and thickness. The size of the aggregate used to create asphalt pavement ranges from 1/2 inch to 3/4 inch (1.27 cm to 1.9 cm). Smaller aggregate is usually used for residential driveways because it gives a smoother appearance. If the aggregate is larger, however, the pavement is stronger.
