Answer (1 of 2): In the Superpave system of pavement design, asphalt cements are graded according to the extreme high and low temperatures at which a pavement is expected to perform. This system is referred to as performance grading and asphalt cements are typically specified in terms of a PG gra...


Asphalt is composed of the heavier, longer hydrocarbon chains from crude oil. At US Oil and Refining Company, the most common grade of PG binder, PG 64-22, comes straight from the vacuum tower. Other PG binders can be made with simple alterations to the formula as previously noted.


Associated Asphalt supplies PG liquid asphalts in several grades ranging from low temperatures of -28 degrees Celsius to high temperatures exceeding 88 degrees Celsius. Each grade is numbered to indicate the range of ideal temperature for the setting and extended use of each asphalt.

Asphalt. Liquid asphalt is a crude product that has several uses. It makes several products we use every day more convenient and safe. Today, it's refined, and it's classified as a pitch. Its origin is from petroleum crude oil. We use this for road paving. Asphalt occurs as a natural resource in several parts of the world.


The base grade is generally used in corn stabilizing level. The I-5 or top is commonly used for homeowners and businesses. I-4 or Commercial top consist of a mixture of ¾ inches of stone and is used when added stability ans strength is needed for the asphalt.

Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Asphalt occurs naturally in a few places in the world, such as in a lake on the island of Trinidad and in the LaBrea "tar pits" in downtown Los Angeles.

Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.


Asphalt cement and finer aggregate portions provide the mastic that holds the stone in close contact. Typical mix design will generally have 6.0–7.0% medium-grade asphalt cement (or polymer-modified AC), 8–13% filler, 70% minimum aggregate greater than 2 mm (No 10) sieve, and 0.3–1.5% fibers by weight of mix. Fibers are generally used to ...

asphalt cement. Liquid asphalts, either cutbacks or emulsions, are simply modifications of asphalt cements to permit use under conditions not suitable for the basic cement. For many applications, however, more than one type or grade may be used, and in some cases choice of the proper material or materials makes the problem confusing.

Well, the traditional superpave grade is on the order of PG ##-##, this means, for example. A grade of asphalt, say, PG 70-40 is a mix where the 70 stands for the asphalt temp max over the next seven days after layment of 70 degrees and the min experienced temp the grade should encounter is 40 degrees. This means, that this PG 70-40, is where the 70 degrees is the layment …
