The presence of excess asphalt binder on the pavement surface is known as Bleeding. Although bleeding can occur anywhere on the pavement surface, it is of most concern in the wheel-paths as it can impact driver safety.
Surfaces with Bleeding are visibly darker and texture is reduced as the severity of Bleeding increases. High-severity Bleeding can completely obscure the aggregate leading to very low texture.
PavemetricsTM Laser Crack Measurement System (LCMSTM-2) Bleeding algorithm analyzes wheel-path pavement and reports Bleeding according to three user-customizable severity levels: Light, Medium and Severe. Percentage of each wheel-path falling into the Severe category is also reported in order to help flag the most critical locations.
