What is the difference between hot asphalt and cold asphalt?
Hot mix asphalt is is heated for application, which thins the material. Remember those steaming metal buckets you used to see on industrial rooftops? Cold asphalt is liquified with something else besides heat. There are two kinds: Emulsified asphalt is mixed with water and an emulsifying agent. Think of it like salad dressing that does not separate in the bottle. The other kind is called Cutback asphalt and is mixed with a petroleum solvent such as naptha, gasoline, or kerosene. They both are liquids at ambient temperature when applied; then the solvent or water evaporates, leaving the asphalt behind. Look up at asphaltinstitute.org
What two methods for filling the crater on an airfield are used today?
Today, two common methods for filling craters on an airfield are cold patching and hot mix asphalt repair. Cold patching involves using a pre-mixed asphalt material that can be applied directly to the damaged area without heating, making it a quick and convenient solution. In contrast, hot mix asphalt repair requires heating the asphalt before application, providing a more durable and long-lasting fix. Both methods aim to restore the surface integrity and safety of the airfield.
Can you lay asphalt over concrete?
Yes, you can lay asphalt over concrete, but it's important to prepare the concrete surface properly. The concrete should be clean, free of debris, and in good condition without major cracks or damage. A bonding agent may also be applied to enhance adhesion between the two surfaces. Additionally, proper drainage should be ensured to prevent water from pooling, which can lead to issues with the asphalt layer.

How many layers did the plaster of mosaics have?
The plaster used in mosaics typically consists of two main layers. The first layer, known as the bedding or base layer, serves as a foundation for the mosaic pieces. The second layer is the finishing layer, which is applied to create a smooth surface for the tiles. In some cases, additional layers may be added for further detailing or reinforcement, but the primary structure usually involves these two layers.

What is the difference between type 1 and type 2 asphalt?
Type 1 asphalt is typically used for surface layers and has a higher binder content, providing better durability and resistance to deformation, making it suitable for high-traffic areas. Type 2 asphalt, on the other hand, is used for base layers and has a lower binder content, which makes it more cost-effective for applications requiring less strength. The choice between the two types depends on the specific requirements of the paving project, including load-bearing capacity and environmental conditions.
