The laying temperature of PQC is typically between 120-140 degrees Celsius.
PQC stands for Pavement Quality Concrete.
The laying temperature is important for ensuring proper compaction and curing of the concrete.
The temperature range may vary depending on factors such as the type of cement used and the ambient temperature.
If the temperature is too low, the concrete may not set properly, while if it is too high, it may le...
The laying temperature of BC is typically between 120-150°C.
BC stands for Bituminous Concrete.
The laying temperature may vary depending on the type of BC being used.
The temperature should be maintained to ensure proper compaction and adhesion.
Excessive heat can cause the BC to become brittle and crack, while insufficient heat can result in poor bonding.
The laying temperature can be monitored using infrared thermometers

Methods of leakage arresting include pressure grouting, chemical injection, and waterproofing membranes.
Pressure grouting involves injecting a cementitious or chemical grout into the cracks or voids to seal them.
Chemical injection uses specialized chemicals to fill and seal cracks in concrete structures.
Waterproofing membranes are applied to surfaces to prevent water penetration and leakage.
Other methods include epoxy
