INTRAKAT SIAKANDARIS – Construction of the new maneuvering area of Paros State Airport using MOBA Big-Sonic-Ski

MOBACT's technical proposal for the runway paving method:

• The existing layering subsoil (3A) must have accuracies of +/- 3 to 4 cm.

The Finisher will be equipped with the following electronic guidance systems:

1. MOBA-Matic (1 ultrasonic sensor + 1 controller) on one side
2. Big-Sonic-Ski 13m (3 ultrasonic sensors + 1 controller + metal support arms) on the other side

• 1st Asphalt Layer (5cm): For the first strip we need a reference level (seam) on one side, which the MOBA-Matic sensor will "read". On the other side, the Big-Sonic-Ski "reads" the 3A and at the same time smoothes the longitudinal irregularities (waves up to 13m long). In the second strip, the MOBA-Matic sensor reads the "smoothed" surface of the first strip and copies it. On the other side, the Big-Sonic-Ski smooths the undulations of the 3A, as in the first lane.
• 2nd & 3rd Asphalt Layer (5cm & 5cm): The next two layers of asphalt will be done by simply duplicating the 1st layer.

INTRAKAT – SIAKANDARIS ASPHALTICS

Using the above laying method, the final surface of the final asphalt layer will have accuracies of +/-3mm

The advantages of the described method are very important to achieve accuracies and delivery times, with the minimum possible cost for the manufacturer:

• No dowels or seam required (except the first strip for the first layer)
• No workers are required for suture placement
• The movement of trucks is facilitated
• Material saving

The use of a clinometer is not recommended for laying widths of more than 2 lanes. The altitudes on the side of the inclinometer include an error due to its operating principle, which in high-demand projects is not negligible. This error is copied and carried over to subsequent lanes.
