Which characteristic can be evaluated through the Los Angeles Abrasion test?

The Los Angeles Abrasion test is specifically designed to assess the resistance to wear of aggregates. This test involves placing a sample of aggregates in a rotating drum with steel balls and then measuring the amount of material that is worn away after a predetermined number of revolutions. The results indicate how well the aggregates can withstand friction and impact, which is critical for ensuring durable pavement materials.

Understanding the wear resistance of aggregates is essential for highway construction since aggregates must maintain their structural integrity against traffic loads, weather conditions, and other environmental factors. Thus, a high resistance to wear signifies that the aggregates are suitable for use in pavement applications. The test provides valuable data that can help engineers and contractors make informed decisions about material selection for construction projects.

The other options do not directly relate to what the Los Angeles Abrasion test measures, which is why they are less relevant in this context. For example, density and moisture absorption are assessed through different standard tests, not the Los Angeles Abrasion test, and the integrity of asphalt pavements pertains more to other forms of evaluation or testing methods focused on flexibility and structural performance rather than aggregate wear.
