Details on paving operation utilizing mechanized equipment

There is some mechanized equipment which utilizes paving operation given below:

Asphalt paver: It spreads the mixture in a uniform layer of desired thickness and shape, finishes the layer to the desired elevation and cross section. Now a day’s pavers are supported on crawlers and wheels. Its working speed is generally ranges from ten to fifteen feet per minute.

The roller operation: The roller starts as soon as the material is spread. It consists of three phases, initial rolling, and intermediate rolling, finish rolling. Initial rolling compacts the material beyond that imparted by the paver, to obtain practically all of the density it needs. They are to be in good mechanical condition to perform a tight rolling. The rolling has two important areas of rolling, transverse joints are perpendicular to the center line of the pavement and longitudinal joints are parallel to the center line.
