DOWNLOAD EBOOK →The design method for secondary roads is based on AASHO Road Test Results and Virginia's design experience. It is divided into two parts. (1) the evaluation of the soil support value of the subgrade, the thickness equivalencies of the paving materials, and the traffic in terms of vehicles per day; and (2) design considerations such as the determination of the required thickness index of the pavement and the selection of the materials and layer thicknesses to meet the design thickness index.

DOWNLOAD EBOOK →The design method for secondary roads and that for subdivision roads are based on AASHO Road Test Results and Virginia's design experience. For flexible pavements, the methods are divided into two parts: (1) the evaluation of the soil support value of the subgrade, the thickness equivalences of the paving materials, and the traffic in terms of vehicles per day; and (2) design considerations such as the determination of the required thickness index of the pavement and the selection of the materials and layer thicknesses to meet the design thickness index. For portland cement concrete pavements, they are based on traffic only.

DOWNLOAD EBOOK →The purpose of this investigation has been to study the design of flexible pavements in Minnesota with emphasis on how the finding and concepts of the AASHO Road test can be applied to the present Minnesota Flexible pavement Design Procedures. At the AASHO Road Test pavements of various thicknesses were built on one subgrade soil with one material for subbase, one material for base, and one material for the asphaltic concrete surfacing on the main factorial experiment. The base type was varied in a special study. Traffic consisted of about one million applications of ten levels of load. Each of the two lanes on the five test loops had constant weight and axle configuration trucks. Adequate thicknesses have been established, based on performance, which is related to the variation in Present Serviceability of a pavement section with traffic.
