Selected papers from the International Airfield and Highway Pavements Conference 2019, held in Chicago, Illinois, July 21–24, 2019. Sponsored by the Transportation & Development Institute of ASCE. This collection contains 44 peer-reviewed papers on the design, construction, evaluation, and management of airfield and highway pavements.
In 2019 Caltrans Pavement Program developed improved pavement smoothness specifications which provide incentives and disincentives for achieving pavement smoothness. Below are the spreadsheets used to determine applicable payment adjustments for both concrete and hot mix asphalt pavements.
Concrete Pavement Construction Basics Placing dowel baskets Dowel bars transfer heavy loads across joints in the pavement, preventing faulting at the joint that can lead to pavement damage. Practices vary from state to state, but dowel bars are typi-cally required in eight-inch or thicker pavements.

Flexible pavements are those pavements which reflect the deformation of subgrade and the subsequent layers to the surface. Flexible, usually asphalt, is laid with no reinforcement or with a specialized fabric reinforcement that permits limited flow or re positioning of the roadbed under ground changes. The design of flexible pavement is based on load

Arrows show required or permitted movements at intersections. A row of solid triangles indicates that the road user must yield. Pavement markings are also used to alert users to potentially hazardous conditions ahead. A letter X with a letter R on each side indicates a highway-rail grade crossing ahead. A hollow triangle indicates a yield ahead.
