Bituminous laying temperature is 130-150°C and rolling temperature is 80-100°C.
Bituminous laying requires higher temperature than rolling.
Temperature range ensures proper compaction and adhesion.
Temperature can vary based on the type of bitumen and aggregate used.
Proper temperature control is crucial for quality bituminous pavement.
Material suitability criteria for aggregate in construction projects.
Aggregate size should be 26.5 mm or less.
Water absorption should not exceed 2%.
Soundness test should show Naso4 not more than 12% and Mgso4 not more than 18%.
Angle of abrasion should be less than 35% with max FI & EI less than 35%.
Equivalent weight of sand should not be less than 50%.
Aggregate should not be alkaline reactive.
MDD & MCC should be as per
The design procedure for DLC mix includes using M15 grade concrete, minimum cement content of 150 kg/cum, and achieving a compressive strength of at least 10 MPA after 7 days of curing.
Use M15 grade concrete with aggregate and cement ratio of 12:1
Minimum cement content of 150 kg/cum, or 120 kg/cum if fly ash content is over 20%
Achieve a compressive strength of at least 10 MPA after 7 days of curing
DLC mix should be hom...
The question is about the suitability of aggregate size and water absorption for PQC with a total thickness of 300mm and tolerance of +/-6mm.
Aggregate size of 31.5mm is suitable for PQC with a total thickness of 300mm and tolerance of +/-6mm.
Water absorption to GSB DLC being the same for PQC is also suitable.
The suitability of the material is important for the successful completion of the project.
The design procedure for cement concrete includes minimum cement content, strength requirements, dowel bar and tie bar specifications, and surface preparation and curing techniques.
Minimum cement content of 360 kg/cum if fly ash is more than 20%, and 310 kg/cum otherwise
Flexural strength of cement concrete after 28-day curing should be 4.5 MPa, and compressive strength should be 40 MPa
Dowel bar size of 32mm dia and 300...

Moisture content is the amount of water present in a material, expressed as a percentage of the total weight of the material.
Moisture content is a crucial factor in construction materials such as soil, concrete, and wood.
It is determined by comparing the weight of the material before and after drying it to remove all moisture.
Moisture content affects the strength, durability, and workability of materials.
High moisture ...
GSB work refers to Granular Sub Base work in civil engineering, which involves laying a layer of compacted granular material as a base for roads or pavements.
GSB work is a crucial step in road construction to provide a stable foundation for the pavement layers above.
It involves spreading and compacting layers of granular material like crushed stone, gravel, or sand.
Proper compaction is essential to ensure the stability...

43 and 53 grade cement differ in their compressive strength and suitability for different types of construction.
43 grade cement has a compressive strength of 43 MPa while 53 grade cement has a compressive strength of 53 MPa.
53 grade cement is more suitable for construction of high-rise buildings and structures that require high strength concrete.
43 grade cement is suitable for construction of low to medium rise buildin...
The size of the pier arm of concourse level depends on the load it needs to support and the design specifications.
The size of the pier arm is determined by the load it needs to support, which is calculated based on the weight of the structure it supports and the live loads it will experience.
The design specifications also play a role in determining the size of the pier arm, including factors such as the height of the s...
