"As a result you

When to Use What Grade of Asphalt and Why

work, as may RC5. When used for this purpose, cover aggregate should follow the asphalt spread as closely as possible. RC4 and RC5 are both well adapted to stationary or travelplant mixing where complete coating and spreading are accomplished with little manipulation on the road. Usually the lighter grade is applied to finergraded materials.

What are Different Types of Asphalt? (with pictures)

Different types are distinguished according to the process used to bind the aggregate with the asphalt. The semisolid form of asphalt, or rolled asphalt, is favored for paving roads in the US. Hot mix asphalt concrete (HMAC) is produced at 320°F (160°C). This high temperature serves to decrease viscosity and moisture during the manufacturing process, resulting in a very durable material

Classification of Aggregates Based on Size and .

When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths, and 20mm size is used for high strength concrete. the size range of various coarse aggregates .

Abrasion of aggregate relate to resistance to abrasion. Both values are important indicators in the provision of hard, sound and durable materials for use in asphalt roadworks. High abrasion resistance of aggregate is of less importance in concrete roadworks, as it does not seem to be an indicator of good abrasion resistance of the concrete.
