The road test used large road user panels to establish the present serviceability rating (PSR) for each test section. Since panel ratings are expensive, a substitute key parameter present serviceability index (PSI) was established. The PSI is based on data on the road's longitudinal roughness, patchwork, rutting, and cracking. Later studies ...

The test reports loss of mass to abrasion and impact, expressed as a percentage of initial sample mass. [7] Maximum acceptable loss for the base course of the road is 45%; the more demanding surface course must be 35% or less. [1] The test was developed by the city engineers of Los Angeles in the 1920s. [8]
