Airfield Paving
These are two types of paving for which we acquired the necessary knowledge and skills. These are uniquely different from pouring slabs for residential and commercial building slabs and driveways.

In the case of airfield paving, (left) extremely low-slump concrete is used. When properly placed, it is thicker, stronger and more abrasion-wear resistant. In the installation of an access ramp to a highway (right), it could be a new ramp to an existing highway, or a replacement ramp. In the latter case two things must be accommodated. First is, whenever possible, recycle the old concrete by means of pulverizing it into a small aggregate that is used for the base of the new pavement. Second, work within time constraints. This may include accelerating the initial hardening process. Since the ramp can only be closed for a limited time work must choreographed into a tight schedule. This access ramp job was done in less than one week.

Airfield paving requires the right skills and equipment to have a successful project. The base must be properly prepared and compacted. Reinforcing members must be accurately placed and tied. Proper form structures must be assembled and be accurately set to the correct level using a laser transit. Concrete is roughly leveled by means of the chute from the ready-mix trucks, and spread with a tool called a come-along. Following this a vibrator is inserted into the fresh concrete every square foot to settle it and release any pockets or entrapped air. It is then dressed and finished with a piece of equipment called a vibrating roller screen. (below)
