The wearing course, also known as a friction course or surface course, is the upper layer in roadway, airfield, and dockyard construction. The term 'surface course' is sometimes used slightly different, to describe very thin surface layers such as chip seal. In rigid pavements the upper layer is a portland cement concrete slab.
This book covers the functional design of roads and highways including such things as the layout of intersections, horizontal curves, and vertical curves.

A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...
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] The California Highway Commission found the new methodology superior to the established Deval abrasion test, and adopted the LA test in 1927. [8]

The measurement of IRI is required for data provided to the United States Federal Highway Administration, [1] [9] and is covered in several standards from ASTM International: ASTM E1926 - 08, [10] ASTM E1364 - 95(2005), [11] and others. IRI is also used to evaluate new pavement construction, to determine penalties or bonus payments based on ...
