is sometimes used beneath the surface layer; ODOT refers to it as #448-Type 2. It has some larger stones in it, which results in some extra strength. 'Base' Asphalt has even larger stones than #448-Type 2, so it provides even more strength as an underlayment; it is known as ODOT #301.

What are the 3 types of asphalt?

There are three main types of asphalt: Hot Asphalt, MC Cold Mix, and UPM. There are also different varieties of these asphalts for summer and winter use. Below is a brief overview of each type of asphalt.

What are grades of asphalt?

The Asphalt Institute specifies four penetration grades: 60-70, 85-100, 120-150, and 200-300. The 60-70 grade is usually used only in pavements where traffic is very heavy such as principle city streets and very heavily trafficked rural highways.

What are the grades of hot mix asphalt?

Hot mix pavements are classified mainly as dense-graded mixes, stone matrix mixes, and open-graded hot mix asphalt.

What are the different sizes of asphalt?

Standard Superpave aggregate rock sizes range from 2 inches to minus #200 fines. Standard Superpave sieve sizes to measure aggregates range from 2 inch (50 mm) to #200 (. 075 mm). Superpave base courses typically use 1.5-inch or 1-inch rock.

What are the numbers in asphalt?

For example, in "PG 64-22," the "64" represents the maximum pavement temperature, in degrees Celsius, for which this binder can be used with low traffic levels. The second number, "-22," signifies the minimum temperature, in degrees Celsius, for which the binder can be used without the likelihood of failure.

What is the difference between Type 3 and Type 4 asphalt?

Type III, is considered to be “steep” asphalt but is limited to slopes up to 2 in 12, and Type IV is “special steep”. The drawback is, the longer it is processed, the shorter the life.
