Chapter 4: Local Road Surface Treatment Options 129 6. Standard Technical Specifications for Local Road Projects Work items for local road projects such as road rehabilitation, maintenance, new construction, upgrading and improvement are recommended to follow the Standard Specifications for Public Works and Highways issued by DPWH (last updated in 2013). There are however special work items that are not identified in the said DPWH Standard Technical Specifications. As an example, standard surface course materials are not available locally. Importing such materials increases the cost of delivery and installation. For this case, local engineering offices may use available local materials provided that it complies with the technical specifications for similar items. For such instances, the local engineering offices should adopt DPWH Revised work items code issued last January 2017 for road projects; Local materials not passing similar technical specifications may mean that the LGU will have to allocate more maintenance works for the subject road where such local materials were used.
