Asphalt pavement is a mixture of graded stone aggregate and asphalt. The asphalt is the binder or glue that holds the pavement together. If left unprotected, asphalt is subject to degradation from oxidation and water penetration. The primary characteristic of all asphalt pavers is a floating screed. The machine must be able to place a consistently smooth, even finish at the proper depth and provide initial compaction. They are capable of placing the concrete at the specified depth with the appropriate reinforcing steel and providing compaction and an initial finish.
Asphalt paver finisher is a mechanically propelled paver provided with heated, fully floating, hydraulically operated vibrating screed with mechanical control for adjustments of height and camber. Paving width ranges from 2.5 to 4.0 mtr and paving thickness up to 205 mm.
Asphalt paving mixtures & blocks are made of asphalt mixed with various other materials. These are mainly used in the construction of roads, parking lots, walkways, and other paved surfaces. Asphalt is a blackish-brown material with a consistency ranging from a viscous liquid to a glassy solid. The primary advantages of asphalt over concrete are flexibility, and durability, because it softens when heated and is comparatively elastic.
