10 Advantages of Concrete as Construction Material | Why - Asphalt - Its 4 [Types, Uses, & Manufacturing Process]

Unlike asphalt, concrete pavement has expansion joints. These joints are areas designed to allow the concrete to shift, in order to relieve any stresses on the surface in a stable way. It's important to note that, even with reinforcing measures, if you pave asphalt over concrete, the asphalt is likely to eventually crack at the joint areas.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.

In addition to its use in asphalt mixtures, they identified unbound base and subbase as "proven" applications for RAP, with grading identified as the limiting factor for use. Although 49 states indicated they used RAP, the primary use was in asphalt concrete.The use of cold mix asphalt concrete for permanent resurfacing reduces inconvenience to the driving public by eliminating the usual secondary step of removing temporary resurfacing and applying hot mix asphalt concrete. It also considerably reduces construction spoil that must be landfilled or recycled.

Although both concrete and asphalt are composed of aggregates, the ingredients used in these mixtures are vastly different and therefore offer different performance levels. The aggregate used in concrete is composed of crushed rock and sand, which is then mixed with cement (the binding agent) and water.concrete (also end-product specifications) are used. The 416 specification is currently used most frequently while 417 is expected to gain more in popularity in the next few years. Specification 408 and 413 are recycled and asphalt-rubber binder pavements respectively. The 409 specification is used for much smaller projects or areas

As a result, warm mix asphalt takes less energy to manufacture and releases fewer fumes, making it a popular choice in areas with poor air circulation. Like hot mix asphalt, warm mix asphalt is flexible, resilient, and often used to pave asphalt roads, driveways, and other types of commercial and residential asphalt pavement.Asphalt concrete is used in the construction of roadways. Cold mix asphalt is primarily used as a patch for road surfaces. Mixed with soap and water, the asphaltic bitumen is emulsified and mixed with the aggregate. As the water evaporates from the mixture, the asphalt hardens and takes on the characteristics of hot mix asphalt concrete.
