At the end of April, SWIETELSKY successfully completed a challenging road construction project for the Traunstein State Building Authority: the rehabilitation of State Road 2357 between Gallersöd and Hochöster over a length of around six kilometres.
As part of the construction work, the section between the AÖ 10 and the B 20 was comprehensively renewed. To this end, the existing road surface was first milled off. This was followed by the installation of an eight-centimetre-thick base course reinforcement and a new four-centimetre-thick surface course.
In total, almost 11,000 tonnes of asphalt were laid. The asphalt mix used was produced at a reduced temperature with foamed bitumen at the SWIETELSKY mixing plant in Emmerting. This process allows the laying temperature to be reduced, contributing to more resource-efficient and lower-emission construction.
In addition to the asphalt works, the verges were also extensively renewed. Around 1,500 tonnes of binding gravel and approximately 500 tonnes of cold mix were used for this purpose. Furthermore, the road markings were renewed as part of the project.
A particular focus of the project was on digital process optimisation. In collaboration with mik-IT, the asphalt paving was planned digitally and monitored in real time. Quality assurance was carried out using, amongst other things, a thermal scanner on the paver and comprehensive compaction monitoring of the rollers.
The construction period specified by the client ran from 15 April to 15 May. Thanks to efficient planning, smooth site management and strong collaboration between all project stakeholders, the work was completed as early as 30 April – two weeks ahead of schedule.
SWIETELSKY would like to thank everyone involved for the successful completion of the project and the professional collaboration.
