The 2000 edition is likely outdated for new projects. TANROADS has issued later revisions (e.g., 2010, 2015, 2022). For current work, try to obtain the latest "Standard Specification for Road and Bridge Works" from TANROADS directly.
If you need the 2000 version specifically for historical reference or contract compliance, contacting TANROADS head office in Dar es Salaam by phone or email is your best option.

The Standard Specifications for Road Works (2000) is the cornerstone technical document published by the Tanzania Ministry of Works to govern the construction and maintenance of the national road network. Developed in collaboration with the Norwegian Public Roads Administration (NPRA), this manual provides uniform guidelines to ensure structural integrity, safety, and longevity for Tanzania's infrastructure. Core Structure of the 2000 Specifications
The document is organized into seven primary "Series," each covering a critical phase of road and highway engineering:
Series 1000: General – Covers definitions, contractual requirements, environmental protection, and traffic accommodation during construction.
Series 2000: Drainage – Specifies standards for culverts, concrete lining, and subsoil drainage systems essential for tropical climates.
Series 3000: Earthworks and Pavement Layers – Outlines the handling of borrow materials, compaction of gravel, and crushed stone layers.
Series 4000: Bituminous Layers and Seals – Defines technical requirements for prime coats, asphalt concrete surfacing, and seal materials.
Series 5000: Ancillary Roadworks – Includes erosion protection, gabions, and road furniture like signs and markings.
Series 6000: Structures – Detailed standards for bridge foundations, formwork, steel reinforcement, and concrete finishes.
Series 7000: Tolerances and Quality Control – Establishesthe testing protocols and allowable deviations for all construction materials and workmanship. Regulatory Context & Modern Application
While the 2000 manual remains a primary reference, it is part of a larger technical framework managed by agencies like TANROADS (for trunk and regional roads) and TARURA (for rural and urban roads).
Complementary Manuals: It works alongside the Pavement and Materials Design Manual (1999) and the Low Volume Roads Manual (2016), which specifically addresses roads carrying fewer than 300 vehicles per day.
Legal Standing: Compliance with these standards is mandatory for all road projects in Tanzania unless a contractor submits an alternative international standard (such as British Standards) for prior approval by the Ministry of Works.
Accessibility: Official copies are typically managed by the Tanzania Bureau of Standards (TBS), though technical summaries and project-specific excerpts are often available through TANROADS procurement portals for bidding contractors. Tanzania Standard Road Works 2000 | PDF - Scribd
The Standard Specification for Road Works (2000) is the cornerstone technical document for the highway engineering sector in the United Republic of Tanzania. Published by the Ministry of Works (MoW) in June 2000, it provides a uniform set of technical guidelines and contractual requirements essential for the design, construction, and quality control of road projects across the country. 1. Background and Development
The specifications were developed through a collaborative institutional framework involving the Ministry of Works (MoW), the Central Materials Laboratory (CML), and the Norwegian Public Roads Administration (NPRA). This project was jointly financed by the Government of Tanzania and the Norwegian Agency for International Development (NORAD). It was designed to complement other core manuals, including the Pavement and Materials Design Manual (1999) and the Laboratory Testing Manual (2000). 2. Core Structure and Series

The Standard Specification for Road Works 2000 (SSRW 2000) is the foundational technical document published by the Ministry of Works in Tanzania. Developed in collaboration with the Norwegian Public Roads Administration (NPRA), it provides uniform technical guidelines and contractual requirements for all national road projects. Purpose and Scope
The primary goal of the SSRW 2000 is to ensure consistency, safety, and durability across Tanzania’s road network. It serves as a standard reference for:
Contractors and Engineers: Defining acceptable workmanship and materials.
Quality Control: Establishing rigorous testing protocols and tolerances.
Procurement: Providing a structured basis for pay items and bidding. Core Series and Structure
The document is organized into seven technical series, each covering a specific stage or element of road construction:
Series 1000: GeneralCovers over 1,150 technical definitions, site administration, and general requirements like site facilities and traffic management.
Series 2000: DrainageOutlines specifications for culverts, side drains, and water management systems to protect the road prism.
Series 3000: Earthworks and Pavement LayersSpecifies standards for the roadbed, subbase, and base courses using gravel or crushed stone. It includes requirements for materials like G25 natural gravel (CBR ≥ 25) and G45 (CBR ≥ 45).
Series 4000: Bituminous Layers and SealsDetailing the application of asphalt concrete (e.g., AC20, AC14) and various bituminous seals used for surfacing.
Series 5000: Ancillary RoadworksCovers "road furniture" such as markings, signs, guardrails, and lighting.
Series 6000: StructuresProvides detailed requirements for foundations, concrete finishes, steel reinforcement, and structural steelwork for bridges and major culverts.
Series 7000: Tolerances, Testing and Quality ControlSets the benchmarks for construction precision and the frequency of material testing. Key Technical Standards and Definitions
The SSRW 2000 integrates specific engineering parameters essential for Tanzanian geography:
Approval: Explicitly requires written confirmation from the Engineer for any deviations or completions.
Material Grading: Uses the Grading Modulus (GM) as a primary measure for aggregate suitability.
Concrete Classes: Defines strength grades (e.g., C50/20) that align with international standards while catering to local bridge and drainage designs. Practical Application in Tanzania Road Works Specifications 2000 Tanzania | PDF - Scribd
