Identify a typical temperature range for asphalt placement.

For asphalt placement, the typical temperature range is critical for ensuring proper compaction and performance of the final pavement. The correct choice, which indicates a range of 250°F to 300°F, reflects the necessary heat to keep the asphalt workable and allow it to bond effectively during installation.

At temperatures within this range, asphalt maintains its flow characteristics, allowing for good compaction under the rollers. This ensures that the asphalt mix achieves the desired density and strength, as well as reduces the likelihood of issues like segregation or premature cooling that can compromise the performance of the paving.

If the temperature is too low, the asphalt may cool too quickly, leading to difficulty in compaction and lower durability. Conversely, higher temperatures can degrade the asphalt binder, potentially leading to problems like raveling or stripping, which affects the lifespan of the pavement. Thus, maintaining the specified temperature range is essential for achieving high-quality asphalt pavement.
