New technologyImprove key road milling jobs

A project to renovate a four-mile stretch of highway and an evacuation line was undertaken by the Ajax Road Construction Company of Florida.，It needs to be doneFull-width Milling Refurbishment and Resurfacing，And some areas need to be redesigned.，During the milling work phase，Ajax Road Construction Company has chosenBlack technology in the field of renovation construction—SmoothRideVariable milling/Paving solutions。Adopt this technology，It can significantly reduce the demand for the technical level and number of construction site personnel.，While ensuring the quality of milling，Greatly improve the production level and overall construction efficiency。The milled surface reshaped by this black technology provides a very smooth foundation for subsequent asphalt paving.。

This project is namedSR-681 Venice Connection Project，Major work on the project included a total of 8 miles of milling and resurfacing，While ensuring flatness and ride comfort，Cross slope adjustment is required，As well as the rectification of guardrails and drainage systems.。To maximize security，On the way toSR-681I-Road surveillance camera equipment is installed on the 75 exit ramp.。

Ajax Roadbuilders is always open to new technologies.，To improve and optimize the construction process.、Smoother and more efficient construction proces。Representatives of Topcon's local distributor, Dixon Equipment Company, with revolutionary solutions in the field of construction SmoothRideVariable milling/Paving solutionsWhen approached by Ajax Road Construction，The company was receptive to this innovative renovation construction technique and decided to apply it.。

Ben, the site technical manager of Ajax Road Construction.·Mr Harlan said：“FromSmoothRideSince the advent of variable construction technology，We have been paying attention to and considering experiencing this black technology for ourselves.，AndSR-The 618 project seemed like the perfect opportunity to put it into official use.。

We like this construction technique very much.，That is, it aims toSimplify the construction process。Whether it's milling or paving，The height difference data provided by the precision positioning sensor andGNSSCombine to carry out 3DSpatial positioning，The perfect combination of the two can provide us with the ideal、High precision 3DDigital construction effect，It is no longer necessary to set up measuring robots or other similar products on site.。Of course，We are proud to be the first roadbuilder in Florida to have this technology.。”

At the beginning of the project，Ben·Harlan uses a pickup truck mountedTopconRD-M1 Pavement Laser Scanning System，ScannedSR-Four miles of north-south lanes.。It can easily and quickly obtain the required road status point cloud data.，Without the need for road closure collection on busy highways.。

“Actually，We split the scan into smaller segments.，So that it is easier to post-process the data later.；Even so，AdoptRD-MThe scanning mode is still much faster than surveyor's survey to obtain road data。With surveyors every 7.Comparison of the way of collecting the elevation of the road section at 5m，UseTopcon RD-M1 laser scanner approx. Per 15cmThe interval gets an exact 3.D（X、Y、Z）Point information，It's definitely faster for us.、More efficient and accurate。”

RD-M1 Realized full-width road surface scanning mode，It can also accurately reproduce the real ups and downs of the road surface.，Provide accurate decision-making and implementation basis for renovation milling design and construction。

Headquartered in FloridaTurtle Infrastructure Partners（TIP）YesLargoLed the implementation of the milling work，He supplied two Wirtgen milling machines for the Venice project.（OneW207FiAnd one equipped withRD-MCVariable milling systemW210-Fi）。Machinery Monitoring Specialist, Location Solutions, Dixon EquipmentBrian TruittExpress，TIPThe company is also Florida.SmoothRideAn indispensable and important participant in the application of technology。

He said：“TIPIn charge of Wittgen'sLevel ProLeveling system and foundation kit（Column、Antenna support, etc）Installed together inW210-FiMilling machine，To support the newRD-MCApplication of variable mil technology。It should also be pointed out that，Not only will AjaxRD-MCSolutions are applied to more projects，They can also specify in the tender contract，Any milling company will need to complete the milling construction in this manner，So that Ajax can successfully complete the paving work.。This ensures that the construction will be carried out in the best possible way，So it's a win for every company.。”

TIPWittgen of the companyW210-FiComes with a 7 foot wide milling drum andRD-MCMatching combination of variable milling solutions，It has helped Ajax achieve production and construction efficiency of nearly 1000 meters per day.，It was hard to imagine before that.，More may require overtime and more machinery and manpower to complete.。

HuntIntroduce：“UseRD-MCAfter variable milling technology，But also greatly simplifies the paving construction work after milling.。”This is mainly due toRD-MCThe variable milling system provides a very flat surface to be paved，This makes the asphalt paving process very easy to control，Make Paving Construction Work Easier。”

 

 

HuntSay：“UseSmoothRideTechnology can help us optimize and adjust the cross slope.，To ensure that we get the desired milling effect and paving thickness control。This is very important，Because when an incorrect cross slope is used for paving control，You may waste more material in the paving operation。Based onRD-MCSupport of variable milling system，It makes our paving process very smooth and confident.，And the reserve of surplus asphalt concrete material is almost eliminated.，This was hard to imagine before.。”

HuntFinally, I concluded：“In this project，We milled about 35500 tons of material.，About 31680 tons of bituminous material was laid on the new road surface.。The milled material will be recycled.，And used in new asphalt recycling and paving projects.。”Contribution : ICTIntelligent Construction Business Department YJ
