Recently, at the paving site of the repair and maintenance project on Provincial Highway Pingqingyue Line (S252) in Tangshan, Hebei Province, Vögele 3D paving technology was successfully applied, achieving millimeter-level control of paving. Click to watch the intelligent paving site.

Project Overview

As an important component of the Beijing-Tianjin-Hebei transportation network, Provincial Highway Pingqingyue Line has faced increasingly severe traffic pressure in recent years. Problems such as aging road infrastructure, severely damaged pavement, and outdated traffic safety facilities have become increasingly prominent, making it difficult to match the growing traffic load demand under the background of Beijing-Tianjin-Hebei coordinated development.

If the traditional balance beam leveling process were adopted, the pavement smoothness problem could not be fundamentally solved. To solve this problem, the contractor actively explored the use of an entirely new technology, namely Vögele 3D automated paving technology, which ideally solved the difficulty in actual construction.

Location: Tangshan, Hebei Province

Models used: SUPER 1880 L, SUPER 1900-3 L

Paving width: 10.5 m

Paving thickness: 4-5 cm

Paving speed: 2.5 m/min

Construction highlights: The Vögele SUPER 1800 L/SUPER 1900-3 L are both equipped with the 3D intelligent paving package and 360° active prisms, adopting high-precision robotic intelligent total station technology. On-site operators only need to input the required three-dimensional data such as pavement coordinates, elevation, width, and steering into the system in advance, and the paver can automatically control its travel and paving according to the parameters.

Vögele's 3D intelligent paving technology came into full play. The Navitronic Plus 3D automatic control system can fully automatically control the screed width, the paver's travel and steering, with no need to set guide lines; through the laser total station, it can travel fully automatically along the specified route.

Moreover, 3D paving also overcomes the problems of traditional paving, which relies on manual measurement of reference stakes and is susceptible to environmental interference leading to uneven thickness and fluctuations in smoothness. The construction process is carried out according to design parameters and standards, ensuring that key indicators such as smoothness, elevation, compaction degree, and transverse and longitudinal slopes meet requirements, greatly improving paving quality.

In addition to high-quality construction results, Vögele 3D intelligent paving technology can also minimize waste of raw materials and large time and labor costs, achieving both economic and environmental benefits through intelligence and technological innovation, helping customers reduce costs and increase efficiency.

In the subsequent compaction stage, the high excitation force of the HAMM HD 128 and HD 138 tandem rollers can ensure uniform and efficient compaction of thick layers from top to bottom, and form excellent compaction smoothness by virtue of high static linear pressure and strong excitation force, ensuring compaction and smoothness.

Millimeter-level precision control

• Full automatic control of paving thickness, width, and slope based on three-dimensional spatial coordinates, with precise control of elevation error and smoothness.

Process innovation advantages

• Elimination of traditional setting-out, stake driving, and line hanging procedures, reducing manual operations; work efficiency greatly improved and construction period shortened.

Intelligent construction management

• Real-time dynamic monitoring of 12 core parameters such as paving thickness, temperature, and speed;

• Data automatically uploaded to the cloud, enabling traceable management of construction quality.

The successful application and smooth demonstration of Vögele 3D paving technology this time not only verified the technology's remarkable effect in improving pavement smoothness, but also set a new benchmark for the efficiency and quality of pavement maintenance projects. More than 80 people, including members of the Party Leadership Group of the Hebei Provincial Department of Transportation, the Provincial Highway Development Center, and technical supervisors from municipal and district transportation bureaus, observed on site and jointly witnessed the new breakthrough in digital construction.
