INTRODUCING NEW ASPHALT PAVER

HA90C-2 is equipped with new screed – the JPAVER2875. This new screed was developed by A new asphalt paver – the HA90C-2 – was introduced at the Shanghai BAUMA 2014. This is a fully restyled model for the world markets and is based on the HA90C which had a JPaver3075 screed. >

ly-awaited dial-style steering system is available. Combinedwith lever operation, it enables fine tuning in the pavement for curved or narrow roads. The operating compartment and both sides of screed have colour moni- tors to display more information than ever including machine status and maintenance intervals. In order to minimise time, workload, cost of preparation and clean up, the screw has been changed to a quick-re- lease type that covers up to 7,5 m pave- ment while the retaining plate has been changed to optimise this new screw. Currently, the total length of high- ways has exceeded 100 000 km in China and road repair and maintenance proj- ects are expected to play an increasingly important role due to the increase of traffic and the aging road infrastructures. The newly launched HA90C-2 is developed based on the study of the paving operation in repair projects and is in line with the requirements of new road building projects. As such it achieves maximum usability.

reinforcing the rigidity of the existing JPAVER3075. The modifications has so far achieved high pavement precision and usability. Additionally, its transportation width has been improved to 2,8 m, meeting the target of less than a 3 m transpor- tation width. This screed has a variable extension system from 2,8 m to 7,5 m and can be further extended up to 9 m by adding two sets of 0,75 m extension screed on both ends. The board operation is now hydrau- lic-driven, leading to easier operation and further improvement of pavement precision. As for heating method, an electric heating system is available in addition to an LPG heating system. The hopper length has been extended by 200 mm to adjust to the big-sized damp track commonly used in China. The height of the hopper front is lowered to 550 mm and the eager-
