Grading & Pulverizing

Grading Tucson Asphalt understands that a long lasting structural pavement section is dependent on good line and grade, quality base materials and an overall design that will support the type of traffic it is intended to accommodate. Tucson Asphalt understands the importance of Grading and knows how to build pavement sections that last.

Subbase Typically local soils which vary greatly in their ability to support a load must determine the required thickness of the overlaying layers.

Compaction is usually accomplished through vibration and static weigh of rollers over newly placed asphalt to condense the mixture to a minimum practical volume, to mold it within form shapes and around embedded parts and reinforcement, and to eliminate voids other than design entrained air.

Pulverizing Asphalt Pulverizing is the process of breaking up the existing pavement and blending it in to the existing base. The new base is re-compacted, graded and made ready for paving. Pulverizing is a very cost effective way to reconstruct your existing pavement. This process eliminates excavation, haul off and landfill costs associated with removing your existing asphalt. Pulverizing adds larger aggregate and structure to the base, thereby giving you a stronger base than what had existed previously.
