and road-related structures, ensuring uniformity and quality across the Emirate's transportation network Overview of Part 3: Pavement
Specific material thresholds, approved manufacturing lists, and performance rules.
A. Mock-ups: Before full-scale execution, the Contractor shall construct mock-ups for architectural finishes, façades, and paving for approval by the Engineer. Approved mock-ups shall serve as the benchmark for quality. B. Method Statements: No work shall commence until a detailed Method Statement has been submitted to and approved by the Consultant/Engineer.
Welders must be certified to AWS D1.1 or structural Eurocodes, with mandatory ultrasonic or radiographic NDT on critical joints.
The geographical landscape of Abu Dhabi features high ambient temperatures, aggressive soils containing sulfates and chlorides, and high humidity along the coast. Concrete in this region is highly susceptible to reinforcement corrosion and chemical attack. Part 3 addresses these vulnerabilities with rigid material mandates. Cementitious Materials and Blends
Ground improvement techniques such as vibro-compaction, dynamic compaction, or soil replacement.
Integrated at 5% to 10% for high-strength, low-permeability applications like high-rise columns or marine structures. Aggregate and Water Quality
Requirements for adjusting moisture content to within a narrow percentage of the Optimum Moisture Content (OMC). Subgrade Preparation
Sampling frequencies, testing methodologies, and compliance documentation. 2. High-Performance Concrete Requirements
