Book Description
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.

Book Description
A design method for secondary roads (based on AASHO Road Test results and experience in Virginia) is described which consists of two parts: 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 planning actions. The References are classified under of the required thickness index of the pavement and the selection of the materials and layer thicknesses to meet the design thickness index. Figures illustrate soil support values and soil resilience factors. The thickness equivalency values for materials used in secondary roads are tabulated as well as slab and bare thickness for different traffic categories. A nomograph correlating the soil support value, traffic and thickness index is presented.

Book Description
The design of secondary and subdivision roads in Virginia is based on the design charts recommended by the Highway Department. In view of recently gained knowledge of materials and design techniques, the Pavement Research Advisory Committee requested that a new design procedure for these roads be developed. In the proposed design developed, the soil support value of the subgrade has been evaluated in terms of soil resiliency and CBR values. Soil resiliency values for any part of Virginia are given in the report or could be easily determined. The design is based on average daily traffic with 0 to 5 percent trucks. Provision has been made in the design for increased truck traffic. The proposed design method is based on the AASHO Road Test Results (1962) now being used in many states, including Virginia. This design was arrived at after personal interviews with the district materials engineers and the evaluation of the designs recommended by them during the last twelve months. In essence, the same pavement designs could be obtained by using the proposed method or the present design charts. However, this method provides the designer more choices in the uses of materials and thus may lead to economies.
