2007 – World Bank - The Otta Seal Surfacing An economic and practical alternative to traditional bituminous surface treatments

Prepared for the World Bank, this

publication has two main objectives:

 

• To summarise more than 25 years of experience with the global use of Otta seals and to provide technical evidence and economic justifications for its consideration for use

in all countries.

• to provide state-of-the-art information on the provision of the Otta seal surfacing as an economic and practical alternative to more traditional surface treatments.

 

The publication will provide the required guidance to a wide range of stakeholders including politicians, practitioners, consultants and contractors, as well as material suppliers, donors, road users and, importantly, Road Authority personnel - who may be considering the use of the Otta seal in their countries.

 

By promoting an innovative approach to the provision of bituminous surface treatments, this publication will undoubtedly lead to a more efficient use of available resources. This will result in direct benefits to many countries and will facilitate socio-economic growth and development and much needed poverty reduction. This publication also provides a useful list of references on the design, construction and maintenance of Otta seals.
