Training Services on the Use of the DCP Pavement Design Method for Low Volume Sealed Roads in Kenya. Training Report - Final, with Annexes

Abstract

Training in the DCP Design Method for Low Volume Sealed Roads was carried out successfully in the period 22 January to 7 February, 2014 for a total of 65 participants from various roads agencies and other organisations in Kenya as well as 3 engineers from Tanzania who had been invited by AFCAP.

The training entailed three days of field training in the use of the DCP equipment for data collection and three classroom courses for Senior Management, Designers / Practitioners and Technicians in the design principles for Low Volume Sealed Roads (LVSRs) and the use of the DCP software for data analysis and design.

The DCP-DN design method differs in a number of respects form the more traditional CBR based pavement design methods and provides the scope for attaining more economical designs of LVSRs. This is achieved by ensuring that the design is carried out in an “environmentally optimized manner” whereby optimum is made of the local materials and the pavement design is matched to the road environment at a local level. When judiciously applied, the DCP-DN design method will produce LVSRs that are “fit for purpose” and facilitate access provision in the most economical manner. These design concepts were discussed at length during the training so as to engender a thorough understanding by the trainees.

The trainees that attended the courses have reached an intermediate competency level. More training is needed for them to reach advance level when they will be able to undertake with confidence a full scale design on their own. It is recommended that advanced training courses should be planned for the near future in order to build and sustain the momentum created by the training intermediate level courses.

Four trial projects designed by the DCP Method are currently being constructed in Central Province. It is recommended that more demonstration sections be constructed adjacent to sections designed by traditional methods for monitoring and confidence building before it is applied full scale and adopted in national standards.as an alternative method of design.

The main report summarises preparation and execution of training and evaluates the training programme. The Annexes include powerpoints of the training modules, attendance details and activity summary.
