Design Manual for Low Volume Sealed Roads Using the DCP Design Method
Abstract
The main purpose of this Manual is to provide practitioners with a rational, appropriate and affordable approach to the design of LVSRs in Malawi. This is achieved by consolidating in one document the latest approaches to the provision of LVSRs including developments in pavement design and surfacing technology and use of road building techniques that allow maximum use to be made of local materials.
The Manual applies primarily to the upgrading of existing unsealed LVRs to a sealed standard using the existing alignment to the maximum extent possible. However, the method can also be used for the design of new roads albeit with a slightly different approach to the evaluation of the in situ conditions and to the construction techniques required. The design is based on the Dynamic Cone Penetrometer (DCP) and is aimed at achieving a balanced pavement design whilst optimizing the in situ material strength in the existing gravel road.
