Premix carpeting is a mixture of aggregate and gravel spread and rolled to a total thickness of 6 to 8mm.
Premix carpeting is a type of road surface that is commonly used for low-traffic roads and driveways.
It is made by mixing together aggregate and gravel, which are then spread and rolled to create a smooth surface.
The total thickness of the premix carpeting is typically between 6 and 8mm.
This type of road surface is ...
Bitumen and aggregate are laid at high temperatures for better bonding and compaction.
High temperature improves the workability of bitumen and aggregate.
It helps in achieving better bonding and compaction.
Rolling at lower temperature ensures that the mixture is not damaged.
The temperature range may vary depending on the type of bitumen and aggregate used.

Using a soil compactor on GSB & WMM layers with a deadload of 12 tons or above can lead to excessive compaction and potential damage to the layers.
Excessive compaction can result in reduced permeability of the layers, affecting drainage.
The excessive force from the compactor can cause cracking or deformation in the layers.
It may also lead to uneven settlement and structural instability in the pavement.

SMA layer is used in high speed expressways for its superior durability, rut resistance, and fatigue resistance.
SMA (Stone Matrix Asphalt) layer provides superior durability compared to traditional asphalt mixes.
SMA layer has excellent rut resistance, maintaining a smooth surface for high speed traffic.
The high binder content in SMA enhances fatigue resistance, reducing cracking and extending pavement life.

Bridges consist of several components that work together to support the weight of the structure and the traffic it carries.
Foundation: supports the weight of the bridge and transfers it to the ground
Substructure: includes piers, abutments, and other supporting elements
Superstructure: includes the deck, girders, and other components that support the roadway
Deck: the surface on which vehicles travel
Parapets: walls or bar...
