The Standard Specification for Roadworks 2000 (often abbreviated as SSRW 2000) is a unified code of practice issued by the Tanzanian Ministry of Works. It was developed to replace older, fragmented colonial-era specifications and to harmonize road construction standards across the country.
Published in the year 2000, its primary goal was to set uniform technical requirements for materials, equipment, workmanship, and testing procedures for all road construction and maintenance projects funded by the Tanzanian government and its development partners (including the World Bank, AfDB, and JICA).
The 2000 edition moved Tanzania towards a performance-based specification.
Projects funded by the World Bank or AfDB frequently host the SSRW 2000 as part of tender documentation. Search for “TANROADS tender documents Tanzania” – the specification is usually appended as Section A of the Works Contract.
The 2000 specification is a snapshot of priorities: durability over short-term cost savings, clarity in measurement to reduce disputes, and prescriptive tests intended to fend off local variations in practice. It also hints at constraints—limited laboratory capacity in some regions, the reality of rainy and dry seasons that define construction windows, and the economic imperative to favor locally sourced materials.
You can imagine sections that are deliberately conservative—higher compaction requirements, repeated testing—because enforcement in the field can be uneven. Conversely, some clauses likely allow the engineer discretion, a necessary flexibility when a rural site throws up an unexpected aquifer or a communal grave.
A: As of 2025, no complete replacement has been issued. TANROADS has published “Pavement and Materials Design Manual” (2019) and “Bridge Design Manual” (2021) as complementary, not replacing, the 2000 spec.
