- Asphalt is a sticky, black
and highly viscous liquid or semi-solid that is present in most
crude petroleums and in some natural deposits. It is most
commonly modeled as a colloid, with asphaltenes as the dispersed
phase and maltenes as the continuous phase (though there is some
disagreement amongst chemists regarding its structure). In U.S.
terminology, asphalt (or asphalt cement) is the carefully
refined residue from the distillation process of selected crude
oils. Outside North America, the product is called bitumen.
- Asphalt rubber has been
proven over the years to be one of several asphalt options for
noise reduction. Making asphalt rubber is different from making
conventional asphalt. Instead of mixing asphalt cement directly
with aggregates, the process first mixes crumb rubber with the
asphalt cement.
- Asphaltic cement shall be
paid for separately by the gallon. Total pay gallons will be
based on actual AC content when the actual AC content
is within 0.2% points of the AC content specified by the
Engineer. Surface treatment of Asphalt operations will be
permitted only during daylight hours, when conditions are dry
and when wind does not adversely affect the spraying operation.
- Asphalt emulsion is of
considerably lower viscosity than asphalt itself (100–4,000
Poise), allowing it to be used at lower temperature.
Lowtemperature techniques for construction and maintenance
reduce emissions, reduce energy consumption, avoid oxidation of
the asphalt, and are less hazardous than techniques using hot
asphalt.
- A research project was
undertaken to evaluate the performance of cold in-place recycled
(CIR) asphalt projects in the state of Iowa. A sample
of eighteen roads was selected. It involves milling and crushing
the existing asphalt pavement, rejuvenating the existing asphalt
cement, and finally placing and compacting the material to a
specified thickness.
- Cracking is one of the two
main concerns considered in the pavement design process (the
other being rutting); it is the primary mode of deterioration in
asphalt cement pavement. Crack repair consists of crack sealing
and crack filling. Usually, crack sealing refers to routing
cracks and placing material on the routed channel. Crack
filling, on the other hand, refers to the placement of material
in/on an uncut crack.
- Stripping in hot mix
asphalt (HMA) Project refers to the loss of adhesion between the
asphalt cement and the aggregate surface primarily caused by the
action of moisture and moisture vapor. The objective of this
project was to develop an asphalt pavement survey protocol using
nondestructive techniques to efficiently detect asphalt
stripping in in-place pavement sections.
- Construction and
maintenance costs for the U.S. roadway infrastructure are
approximately $100 billion/year, about 1 percent of the U.S.
gross domestic product. Asphalt paving is the largest component
of this cost, representing about 20 percent of the total. About
95 percent of the paved roads in the United States are surfaced
with asphalt, and most are produced using hot-mix construction.
- Fortunately for the US and
Canadian asphalt market, the Venezuelan strike has come at a
time of the year when paving demand is at its lowest. Asphalt
demand in southeast Asia remained weak. Marketers reported that
the crude price strength and tightness in the wholesale asphalt
market has put pressure on quotes. One supplier reported its new
Midwest quotes to be in the $165- 180 fob range, depending on
the area.
- Asphalt is a refining
byproduct Approximately 3% of a barrel of oil is asphalt, Paving
represents 74% of all asphalt sold, OC Trumbull® is the market
leader in processed asphalts. Products include coatings for
shingles, bulk and packaged asphalt for commercial roofs, and
industrial and specialty asphalts.
- Global demand for
asphalt in roofing applications is expected to approach
12million metric tons. Growth in the Asia/Pacific region, the
Africa/Mid east region and Eastern Europe will help offset a
deceleration of demand in the large US market. Building
construction activity in developing countries will generate
opportunities for asphaltic membrane roofing
