Description

Asphalt is a material composed of granular materials such as sand or crushed stone. and bitumen, a petroleum-derived binder that gives asphalt its waterproof properties. When bitumen and aggregate are mixed together at high temperatures, the result is asphalt. Asphalt has been used by civilizations for thousands of years. originally asphalt was used for waterproofing and as an adhesive. Today, it is most commonly used in road construction. When properly installed and maintained asphalt surfaces can last up to 15 years.

Import Quantities to the Port of Baltimore

Asphalt plays a vital role in construction and infrastructure development across the United States. Efficient distribution hubs such as the Port of Baltimore are essential to meet this national demand. The Port of Baltimore is currently the largest importer of asphalt among U.S. ports. According to ImportInfo data, in 2024 the Port received approximately 159039.016 tons of asphalt, primarily from Canada, with additional shipments from Greece, Italy, and other countries. In 2023, imports were estimated at about 4,000 barrels per day. Although imports temporarily declined following the 2024 collapse of the Francis Scott Key Bridge, shipments remained substantial, underscoring Baltimore’s key role in U.S. asphalt distribution.

Uses

Asphalt’s versatility allows it to be used for a wide range of applications, including roadways, highways, parking lots, and roofing. It is cost-effective, low-maintenance, and durable, making it an ideal surface material. There are two main types of asphalt mixes: hot mix and cold mix. Hot mix asphalt, heated to between 300–500 degrees Fahrenheit, is used for large-scale projects such as highways and parking lots. Cold mix asphalt is primarily used for smaller repairs, such as filling cracks and potholes, and though less durable than hot mix, it is more affordable.

How It Works

The process of asphalt paving generally includes six key steps: site preparation, base installation, mix production, transportation, placement, and compaction. Proper site preparation, including debris removal and grading, ensures stability and effective water drainage. The asphalt mix—composed of aggregate, binder, and filler—is typically produced at an asphalt plant and transported while hot to the work site. Once placed, it is spread evenly and compacted to achieve a smooth, durable surface. The final step, surface finishing, provides a uniform texture and enhanced durability.

When properly installed, asphalt pavements produce smooth, resilient surfaces ideal for vehicular travel. They offer strong weather resistance and can withstand heat, rain, and freezing conditions. Asphalt is also among the most recycled construction materials—old asphalt can be reheated, reprocessed, and reused in new projects. Its affordability, fast installation time, and noise-reducing qualities make it a preferred material in road construction. Additionally, the dark, polished finish of freshly installed asphalt contributes to a clean, professional appearance on roadways and parking lots
