Binhuai Expressway
Study on Intelligent Compaction of Soft Soil Subgrade
The expressway from Binhai to Huai'an is the planning of the expressway network in Jiangsu Province.（2017-2035）New line in，The starting point is located in the coastal port area of Yancheng City.，The terminal point is in Lianshui County, Huai'an City.。
In the near futureResearch Group, School of Transportation Engineering, Tongji UniversityCarried out on“Binhuai ExpresswayBHIntelligent Compaction Test Section of Soft Soil Subgrade of Bid 5”Research on the subject。
Relying on Binhuai Expressway，ExploreInfluence Factors and Optimum Compaction Technology of Soft Soil Subgrade Compaction。Through the data analysis of the test results, the influence degree of each factor on the subgrade compaction effect is obtained.，And an intelligent compaction index is obtained by fitting the test data.、Function model of rolling moisture content and rolling times，At the same time, an optimal construction compaction process is determined.，ThusGuide the subgrade compaction construction of non-test section。
Reasons for choosing BMW
Practice is the basis of theory.，It is well known，Subgrade compaction is an important part of highway construction.，In the expressway, because of the high roadbed height,，Large demand for filling、The source is unstable，Therefore, there are higher requirements in the compaction process.。
The use of intelligent compaction machinery can accurately study the compaction effect of different soils.，Strive to optimize the construction process，Purpose of cost savings。
Domestic companies started late in intelligent compaction technology.，Lack of complete data support，After many investigations，The research group finally locked its eyes on BMW.。Hardware：Baomag equipment has comprehensive functions.，Close to the current construction requirements and the equipment can change a variety of parameter gear，It is helpful to carry out research；Software aspects，BaomagHave decades of data accumulation，Based on this, a model is established.，Used to analyze smart compaction data，Establishment of intelligent compaction index，Be able to give precise guidance during construction。

Baomag——Pioneer of Intelligent Compaction Technology
As the field of compactionGlobal market leader，BMW has set the standard and example for the whole industry.，Developed a large number of technologies，System for measuring and recording compaction。
ECONOMIZER
Soil compaction quality can be measured continuously throughout the compaction process。The system can identify areas that have been compacted and locations where compaction is weak。The current compaction progress can be viewed at any time by the roller driver or the plate tamper operator，So you know exactly when, where and what to do.。Know exactly where compaction is required。Maximum number of compactionCan be reduced by 25%。The amount of work required for soil compaction is greatly reduced。The production efficiency of the whole construction site is not affected at all.。
TERRAMETER
Real-time surface inspection,In earthworks，The stiffness of the material is typically measured using a pressure plate as a reference。However，The pressure plate can only measure certain points，And it's expensive。TERRAMETER The technology can do more.。The measuring system enables the BMG single drum roller to be a rolling platen.：Covered compaction surface in real times。
BOMAP
Use BOMAPReal-time monitoring of compaction results of soil and asphalt，Machines from different manufacturers can be connected。With the aid of an auxiliary system，The degree of compaction at the construction site can be easily checked and recorded.。The roller driver can immediately see that the ground floor has been compacted to the optimum degree，Or if further compaction is required。
The system operates without any additional special hardware。BOMAP Use the built-in for mobile devices GPS To detect the location of construction machinery at earthwork or asphalt construction sites。The system is plug and play。BOMAP Compaction results may be recorded from any manufacturer's roller，The driver does not need to make any additional settings。
From a system for measuring and recording compactionECONOMIZER 、 TERRAMETERTo techniques for managing an entire group of machinesBOMAP，Decades of experience、Expertise and focus on product quality，Guaranteed BOMAG Technology consistently responds to any challenge。
