Asphalt Paving Materials 2-5 ASPHALT CONCRETE Asphalt Concrete is known by many differ-ent names: hot mix asphalt, plant mix, bituminous mix, bituminous concrete, and many others. It is a combination of two primary ingredients - aggregates and asphalt cement. The aggr egates total 90 to 95 per cent of the total mixture by weight. They are mixed


used to predict long-term susceptibility to stripping of an asphalt concrete. To combat the effects of water damage, an anti-stripping additive is used in all asphalt mixes. The Contractor, in most cases is required to use 1.0 percent hydrated lime in the mixture.


Asphalt concrete is a mixture mainly composed of mineral aggregates, asphalt binder, and additive, and has been widely applied in pavement construction. As an adhesive material, asphalt binder is considered to have predominant effects and contributions on whole asphalt pavement performance. However, being susceptible to temperature, asphalt ...

Pavement Rehabilitation

Asphalt pavements are also rehabilitated using a conventional concrete overlay or the newer technique of ultrathin whitetopping (UTW). The UTW technique is of recent origin and long-term performance data are not yet available. Concrete Pavement Rehabilitation Concrete pavement rehabilitation may involve use of concrete pavement restoration (CPR)

What is the Difference Between Asphalt and Concrete?


Bituminous concrete is also known as asphalt. Bituminous concrete is a type of construction material used for paving roads, driveways, and parking lots. It's made from a blend of stone and other forms of aggregate materials joined together by a binding agent. This binding agent is called "bitumen" and is a by-product of petroleum refining.


Asphalt concrete, also known as bituminous concrete, is a mixture of crushed stone or crushed gravel, stone chips or sand, mineral powder, etc. with a certain proportion of road asphalt materials, mixed under strict control. Asphalt concrete is usually used for runway, highway, airport, garden road, traffic navigation and many other types of ...


At one time it was thought that a prime coat was an essential element of good pavement construction. However, in recent years some engineers have eliminated the use of a prime, especially when asphalt layer(s) (surface and/or base) is 4 inches or more in thickness.
