It is very much pertinent to consider the properties of bituminous binders and the bitumen content in a mix while attempting for enhancing the performance characteristics of bituminous mixes. The construction sector is interested in using a right type of bitumen for obtaining durable pavements with longevity of 1015 years especially for BOT (build, operate, and transfer) type projects.

Fine Aggregate Angularity – Pavement Interactive

Fine Aggregate Angularity – Pavement Interactive

Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test. The FAA test estimates fine aggregate angularity by measuring the loose uncompacted void content of a fine aggregate sample. On a sample of known gradation, the ...
