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.

You might wonder: “Is a document from 2000 still valid in 2024/2025?” The answer is While newer guidelines and addenda have been issued (e.g., for asphalt concrete design, environmental mitigation), the 2000 edition remains the master reference for contractual disputes, baseline testing, and unit rate billing. No subsequent document has fully replaced it. Instead, projects often issue “Supplementary Specifications” that modify specific clauses of the 2000 document.
The specification outlines the following requirements for road design: standard specification for roadworks 2000 tanzania pdf
Adds erosion control, borrow pit rehabilitation, and dust suppression requirements not detailed in the 2000 version.
Details specifications for prime coats, tack coats, and surface dressings (chipseals). Governs the production and laying of Asphalt Concrete (AC).
This section governs the concrete and steel works required for minor and major structures. It outlines concrete mix designs, characteristic strengths (e.g., Class 20, Class 30 concrete), reinforcement steel placement, and formwork removal timelines. 3.

For all paving and roadworks in Tanzania, the SSRW 2000 is the mandatory standard. All tender documents and contracts explicitly reference it as the governing standard for work execution. The document is also the primary reference for resolving technical disputes during procurement and construction, as seen in multiple TANROADS tender clarifications.
Standard Specification for Road Works (2000) is the primary technical guideline for road construction and maintenance in Tanzania, published by the Ministry of Works in collaboration with the Norwegian Public Roads Administration. Accessing the Full Document (PDF)

In the realm of civil engineering and public works, a specification is more than just a document—it is the legal and technical blueprint that dictates durability, safety, and cost-effectiveness. For Tanzania, that blueprint is the .
