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
Is asphalt the same as blacktop?
Yes. These are two different names for the same thing.
What kind of material can be used for driveway paving?
Cement is a material that can be used for driveway paving. Two more, very diverse options for paving ones driveway are asphalt and pea gravel. Asphalt and cement are the two of the three most commonly used options.
What is the difference between tack coat and prime coat?
There is a substantial amount of misinformation concerning the function and proper use of prime. Prime is not glue-causing the base to adhere to the pavement is not its purpose. Prime's purpose is to protect the base from rain and light traffic, when the paving will be delayed.A prime coat is an application of an asphalt cutback or emulsified asphalt to a prepared base. The base can be either a sub grade or a base rock. Prime functions as a protector from rain for both types of bases. A primecoat should not be confused with a tack coat. Tack is an a adhesive for gluing two asphalt layers together.
Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?
True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.
How many layers of shingles can be put on your roof?
Usually not more than two.

What does it mean to have medium layers?
Short layers is when the shortest cut of your layers are high on your head. Long layers is when the shortest cut of you layers are within a few inches of the longest length of hair. Medium layers is somewhere in between the two, usually when your layers start at ear or chin level.
How many years do you have to go to college to be a Associate in Applied Arts?
An Associate in Applied Arts is usually two years. You won't be an Associate in Applied Arts though, you will have one.
What fields do metal honeycomb board usually be applied in?
Aerospace and defense are the two biggest customers for this product.
Can DVDs be recorded on two layers?
There are such things as Dual Layer DVD's, DVD-R9. They have two data layers and a capacity of around 8.5GB, and require a special burner to write to them, though can usually be read by most normal readers.
How many layer on the intensifying screen?
Intensifying screens typically consist of two layers: a base layer that supports the screen and a phosphor layer that converts X-ray energy into visible light. The phosphor layer is usually applied on both sides of the base layer to maximize efficiency.
What is the difference between monolithic ceramic and mutilayer ceramic capacitors?
Ceramic Multilayer vs Monolithic CapacitorBoth multilayer and monolithic capacitors have multiple layers. The main difference between the two is the manufacturing process. Monolithic capacitors have a paste of ceramic material applied between the conductive layers. After this paste is applied the capacitors are then baked. Multilayer capacitors have the ceramic material sprayed onto the conductive layers. This generally means that monolithic capacitors can't go as high in capacitance because the amount of layers is limited due to their manufacturing process.
What are the two physical layers of earth?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What two layers of the earth are densest?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What is asphalt sidewalk made of?
Asphalt usually means one of two things: 1) asphalt cement or 2) asphalt pavement. Asphalt cement, also called bitumen, is a viscous black liquid refined from crude petroleum or mined from natural deposits. When asphalt cement is heated and mixed with aggregate, it can be used to create asphalt pavements, also sometimes called tarmac or blacktop. The exact composition of a pavement depends upon the project specifications and intended use, but they generally contain a mix of fine and course aggregates (rocks and sand) of differing sizes. About 5% of a typical asphalt pavement is made of asphalt cement, which acts as a binder to hold the aggregate together.
Is asphalt the same as blacktop?
Yes. These are two different names for the same thing.
