Study on Asphalt Pavement Surface Texture Degradation Using 3 ...

Surface texture is a very important factor affecting the anti-skid performance of pavements. In this paper, entropy theory is introduced to study the decay behavior of the three-dimensional macrotexture and microtexture of road surfaces in service based on the field test data collected over more than 2 years.

Types of Bitumen Mixes for Pavements -Applications in Road

To facilitate medium and low traffic, a bituminous concrete grade of nominal maximum aggregate size 9.5 mm was necessary to considered for the construction of smooth and impermeable pavement in urban areas. To facilitate thin asphalt lifts, bituminous concrete grading-3 is more suitable than grade-2.

Differences Between Concrete and Asphalt Pavement

Differences Between Concrete and Asphalt Pavement. Historically, pavements have been divided into two broad categories, rigid and flexible. These classical definitions, in some cases, are an over-simplification. However, the terms rigid and flexible provide a good description of how the pavements react to loads and the environment.

What are Different Layers in a Bituminous Pavement?

3. Bituminous Concrete Layer. Bituminous concrete layer is a mixture of aggregates continuously graded from maximum size to minimum sizes (typically less than 25mm to 0.075mm aggregates). Sufficient bitumen is added to the mix so that the compacted concrete mix effectively impervious and has acceptable dissipative and elastic properties.
