Kinematic Viscosity
A measure of the viscosity of asphalt, measured in centistokes, conducted at a temperature of 135°C (275°F).
Lane Joint Cracks Longitudinal separations along the seam between two paving lanes.
Lift A layer or course of paving material applied to a base or a previous layer.
Lime Treated Subgrade A subgrade preparation technique in which the subgrade soil and added lime are mechanically mixed and compacted to produce a higher modulus base material than the in-situ material.
Lime-Fly Ash Base A road base material consisting of a blend of mineral aggregate, lime, fly ash, and water, which when combined in proper proportions and compacted produces a dense mass of increased strength.
Load Equivalency Factor (LEF) The number of 80-kN (18,000-lb.) single-axle load applications (ESAL) contributed by one passage of an axle.
Longitudinal Crack A vertical crack in the pavement that follows a course approximately parallel to the centerline.
