Rehabilitating a national highway

Once the carriageway had been precisely milled off by a WIRTGEN W 195 large milling machine, it was time to pave the new surface course. A paving team from the contractor Hangzhou Hongde Engineering Machinery Co., Ltd. used their VÖGELE SUPER 1600 L paver to do the job. Like the prior milling operation, paving was carried out in several sections, each 3.75m wide, amid flowing traffic. Closing National Highway 104 completely was not an option, since the road is so heavily trafficked.

"In this project, it was important to minimize the disruption to traffic and to complete the asphalt paving work as quickly as possible," says General Manager Long Aibing. "The VÖGELE paver did an excellent job from the word go. The performance was spot on and the surface we achieved is absolutely even and of a superb quality.”

Hangzhou Hongde Engineering Machinery Co., Ltd. opted to use the Universal Class paver from VÖGELE because it perfectly matched the company’s range of applications. Indeed, the SUPER 1600 L is a true master of asphalt paving, in smaller and larger projects alike. The excellent experience the company has had with other VÖGELE machines such as the SUPER 1880 L, as well as other WIRTGEN GROUP machines, for instance the HAMM HD 128 tandem roller, added to VÖGELE's appeal.

Asphalt paving on National Highway 104 was completed not only rapidly, but also to a very high quality. The high quality of asphalt paving is crucially evident in the surface accuracy or truth to line and level of the traffic area produced. The SUPER 1600 L tracked paver hits the mark in this respect with its AB 480 TV Extending Screed. It combines great flexibility with high precision, because it is designed for high stability with its single-tube telescoping system. The 3-point suspension enables the pave width to be adjusted gently and quickly without jerking. The tamper and vibrator compacting systems are another key quality feature. The tamper is key here, since it packs the asphalt mix under the basic screed, achieving high degrees of precompaction, and it is this which assures the paving quality and evenness of the resultant pavement across the entire width. “This VÖGELE technology is a particularly great asset when we have to work to a tight schedule, as we did in Yuhang District,” reports Long Aibing.
