Latex paints are suitable for surfaces like wood due to their flexibility and ability to withstand moisture.

Enamel paints, known for their durability and hardness, are ideal choices for concrete and masonry.

The lower the Gauge number of Galvanized Iron Sheets, the thicker the sheet.

The higher the Schedule number of Galvanized Iron Pipes, the thicker the pipe.

PCCP stands for Portland Cement Concrete Pavement, a type of road construction commonly used for roads and highways.

The minimum Free-Haul distance is the distance within which the contractor doesn't charge extra for hauling materials.

The maximum size aggregate for structural concrete should be less than 1/3 of the spacing between the reinforcing steel bars to ensure proper concrete consolidation and strength.

The water-cement ratio is a crucial factor influencing concrete strength. A lower ratio generally results in stronger concrete.

The standard unit weight per meter of 32mm steel bars is 6.314 kg/m.

The maximum tolerance on the mass of one piece of steel bar is +-5.0%.

The Abrasion Test, Grading Cat 500 revolutions, uses 9 spheres.

The maximum Loss of Ignition of cement is 3%.

The types of slump are True Slump, False Slump, and Shear Slump. Collapse Slump is not a recognized type of slump.

The test that determines the amount of asphalt or bitumen in the bituminous mixture is not explicitly mentioned in the provided text. However, it is likely a test such as the Asphalt Content Test.

The minimum depth for inserting a Dial and Armored Stem Thermometer into the mixture is 5 inches.

Bleeding is a common defect in asphalt pavement caused by an excess of bituminous binder.

The minimum weight of Gravity Hammers used in pile driving is 2,500 kg. This heavy equipment is used to drive piles into the ground, creating a solid foundation for various structures.

The unit of measure for Timber Structures in the specification is 'Each'. Each timber structure is considered as a separate entity for quantity estimation and billing.

The minimum pull-offs per system or span of Carbon Fiber Sheets is 2. These sheets are typically used for reinforcement and require a minimum of two anchor points per system to ensure proper installation and stability.

The minimum thickness of the bedding material beneath the pipe is 150mm. This ensures a stable base for the pipe, distributing its weight evenly and preventing sinking.

Stones weighing between 60kg and 100kg are classified as Class B. This classification helps in determining the suitability of the stone for various construction uses.

The dimension tolerance for Gabions is +/- 10.0%. This allows for slight variations in the size of Gabions, while maintaining their structural integrity.

The concrete class used for Concrete Slope Protection is Class C. This specific class of concrete is designed to withstand weathering and erosion, protecting slopes from damage.

The concrete class used for Mechanically Stabilized Earth (MSE) Retaining Walls is Class B. This concrete class is designed to provide the necessary strength and durability for supporting the wall.

The maximum size of sand particles allowed in the Field Density Test. Particles larger than this size won't pass through the sieve.

A benefit of compaction is that it reduces the soil's ability to be compressed under load.

The ability of asphalt pavement to bend without breaking, meaning it can adjust to changes in temperature and load.

A device that measures the relative hardness of asphalt by penetrating its surface.

To accurately assess asphalt thickness, you should take measurements at 8 points on the periphery of the core.

The minimum average compressive strength required for load-bearing concrete hollow blocks (CHBs).

A report that documents the quality control of concrete materials, ensuring their consistency and compliance with standards. It needs to be submitted on a daily basis.

A report that summarises all the tests and data collected on a specific material or project. It needs to be submitted on a weekly basis.

The CBR Value for Item 200 should be at least 25% to ensure the material's strength and load-bearing capacity.

The maximum allowable wear for Lime Stabilized Road Mix Base Course is 25%. This means that the road surface can lose up to 25% of its material due to wear and tear.

The amount of cement added to the soil aggregate for Item 204 should be between 3% and 12% of the dry soil's weight. This ensures proper bonding and strength.

Aggregate Surface Course should have a minimum Plasticity Index of 3. This indicates the soil's ability to deform without cracking, ensuring a resilient surface.

The minimum uniform density of crushed slag used for PCCP is 1,210 kg/m³. This ensures the material's structural integrity and load-bearing capacity.

The rate of application for Bituminous Tack Coat is 0.9-1.8 liters per square meter. This optimizes adhesion between asphalt layers.

The rate of application for Bituminous Prime Coat is 0.2-0.7 liters per square meter. This prepares the surface for asphalt by sealing it and improving adhesion.

The unit of measure for Item 307 Bituminous Plant-Mix Surface Course - General is cubic meters. This measures the volume of the asphalt mixture used.

The maximum acceptable value for the Plasticity Index (PI) of Crushed Aggregate Base Course (Item 202).

The minimum volume of each individual stone used in the construction of Hand-Laid Rock Embankment (Item 508).

A concrete mix that contains large aggregate stones, mainly used for structural stability.

The minimum time after hydroseeding that the area needs to be actively grown-in and maintained to ensure successful establishment.

The maximum allowable width at the top of pre-cast curb and gutter components.

The radius of the curved edges of sidewalks and transverse cuts, creating a smooth transition.

The maximum permissible length of bolts used for Guard Rails (Item 603) that extend beyond the nuts when tightened.

This item group includes various infrastructure markers used for guidance and navigation.
