广西Zhuang自治区位于中部中南部，与越南共享边界。广西与东南亚有悠久的贸易历史，东盟国家是广西的主要贸易伙伴。广西由中国中央政府推广，作为东盟市场的开门，并通过高速道路，铁路，港口和机场与东南亚建立联系，并且在广西各地都建造了高速公路，以促进该地区的经济发展。

Nanning and Liuzhou are two major cities in Guangxi. Nanning is an important transport and logistic hub for China’s south-western markets with an inland river port, hub for road and railway networks and an airport that connects to regional and international destinations. The193公里高速公路在这两个主要城市之间，将在2016年期间从四个车道重建并从四个车道延伸到2018年。将两个城市之间的旅行时间降低到2.5小时。

第一次在中国使用Leica Pavesmart 3D

Liuzhou和Nanning之间的双向八车道高速公路。

广西路和桥梁工程集团，道路，桥梁，隧道，子分级和市政工程建筑服务的提供商，已使用了两个Leica PaveSmart 3D solutions和四个iCON robot 61在这个项目。这是第一次that the company uses 3D paving solutions, and it has completely changed the construction process.

“There is no need for manual setting and controlling of stringlines. Using the Leica Robot 61 total station to guide the precise digital construction work ensures that the paving construction is performed strictly according to the design and guarantees the smoothness and flatness of the spread,”广西路和桥梁工程集团产品经理Wei Jingguang。

两家第一个Leica Pavesmart 3D Solutions出售给了中国市场。

The specifications in Guangxi Road and Bridge Engineering Group’s contract were awidth of 42 metres, 4 per cent cement stabilised macadam base with a thickness of 20 centimetres and 5 per cent cement stabilised macadam base with a thickness of 38 cm. The design data are imported into the 3D solution, and the construction process system is automatically controlled,without the need to measure the sample and the reference line。这降低了人为因素对建筑质量的影响，并确保easier logistics on the job site。

“没有过多的建筑人员和建筑辅助人员工作，大大降低了劳动力。干净有序的建筑工地可确保人员和机械设备的安全性，”says Wei.

工作24/7

The construction work is implemented without traffic interruptions, and is being performed 24 hours a day.

“与传统的建设过程相比，莉卡·帕维斯马特3D解决方案的使用是中国铺路行业的真正改变游戏规则。我们估计，我们节省了大量项目时间，并通过向3D技术引入3D技术来确保铺平质量。中国市场，”总结说，Leica Geosystems机器控制业务部中国地区销售经理Xing Lu。
