Automated Spray Pothole Patching Truck, Purdue Ect Team
Automated Spray Pothole Patching Truck, Purdue Ect Team
ECT Fact Sheets
The RA-300 patcher, manufactured by Rosco Manufacturing, Madison, S.D., is a fully automated spray patching road maintenance vehicle, which fills potholes and cracks on the road. A operator can control all patching functions with the control panel and joystick from the safety and comfort of the truck cab.

Digital Hardhat System, Purdue Ect Team
ECT Fact Sheets
The Digital Hardhat (DHH) is a pen-based personal computer (PC) running a Windows operating system, which is used to collect multimedia information such as text, sound, video, and images. This pen-based computer can also be used to communicate between the construction site and other locations using various connection methods including a wireless network connection, which enables a personnel to roam around the site and video teleconference live with others to solve problems collaboratively.

Stay-In-Place (Sip) Formwork, Purdue Ect Team
ECT Fact Sheets
With the recent development of composite materials, SIP system are offering architects and engineers numerous advantages over competitive systems such as maximum flexibility, cost saving, and efficient time control in the various construction field; residential, commercial, industrial building and bridge as well. SIP systems have been applied to various type of project providing various panels composed of synthetic materials such as polyvinyl chloride (PVC), galvanized coiled sheet steel, fabricated steel, carbon/epoxy thin shell and so on for the specific requirement of each project.
Paslode - Cordless Finish Nailer, Purdue Ect Team
Paslode - Cordless Finish Nailer, Purdue Ect Team
ECT Fact Sheets
The short length (11.75"), better balance and textured super-grip handles of cordless nailer allow a user to be able to work comfortably in cramped overhead and other hard-to-reach places. The Paslode Impulse IM250 II features patented linear combustion engine that is powered by Impulse fuel cells and rechargeable batteries.
Bladepro: 3d Automatic Grade Control System, Purdue Ect Team
Bladepro: 3d Automatic Grade Control System, Purdue Ect Team
ECT Fact Sheets
Currently most of the methods to control grading equipment to achieve the required production accuracy are based on conventional surveying, such as grade stakes and stringlines. BladePro System, developed by Spectra Precision in 1998, is a dual automatic blade control system that uses advance computer technology and user friendly operator controls. This system provides contractors a three dimensional machine control system for roads, railway beds and airport runway construction.
Ar2000 Super Recycler, Purdue Ect Team
Ar2000 Super Recycler, Purdue Ect Team
ECT Fact Sheets
Hot in-place recycling (HIR) is a process for rehabilitating deteriorated asphalt pavements. HIR recycling enables repaving to be 25-30% cheaper than traditional asphalt resurfacing systems and minimizes the disruption of traffic. Martec's AR2000 Super Recycler is a self-propelled equipment train, consisting of two identical Preheaters, a Heater-Miller and a Heater-Mixer as the main units totaling 210 feet (64 m) in length, with a conventional paver, a rubber-tired roller and a vibratory roller added to handle laydown and compaction. This train recycles asphalt pavement in five separate stages: preheating, hot milling, heat and stir, pugmill mixing, and laydown and compaction.
Asphalt Paver Engineering Control Systems, Purdue Ect Team
Asphalt Paver Engineering Control Systems, Purdue Ect Team
ECT Fact Sheets
At present, there are approximately 300,000 asphalt paving workers who are routinely exposed to asphalt fume. Presently, limited data exists concerning the level of exposure and subsequent health effects for paving workers. The engineering control method developed for highway class pavers includes ventilation systems, baffles, and enclosures to capture the generated contaminant within the paver's auger area and to exhaust it before it enters the workers' working environment.
3d-Mc Three Dimensional Machine Control, Purdue Ect Team
3d-Mc Three Dimensional Machine Control, Purdue Ect Team
ECT Fact Sheets
Construction equipment using laser control technology cannot perform curves on a road construction project. The guiding of road construction equipment in curving contours requires references such as hubs, staking, or elevated string lines. The 3D MC system uses three modules to control the piece of equipment: a total station, receiver and control system device. The main benefit of the 3D MC system is the obvious gain of productivity generated by this innovation.
Shaking Table System For Geotechnical Centrifuge, Purdue Ect Team
Shaking Table System For Geotechnical Centrifuge, Purdue Ect Team
ECT Fact Sheets
The shaking table system for geotechnical centrifuge, which can simulate sinusoidal and real seismic waves under a centrifugal force of 50 times earth gravity, is capable of providing significant data for the seismic design of structures. The shaking table can accommodate test specimens up to 250kg under 50G condition, so it can be used to perform various types of ground shaking tests.
Soft Trencher, Purdue Ect Team
Soft Trencher, Purdue Ect Team
ECT Fact Sheets
Excavation near existing electrical lines, gas lines and other underground utilities can be dangerous and time consuming. A self propelled trencher called the Soft Trencher developed by Battelle Memorial Institute, Columbus, Ohio uses supersonic air to loosen dirt which is then vacuumed up into a truck or piled into a windrow for later removal of backfill. The supersonic air used to break up the soil is harmless to underground utilities and cables. Unlike traditional excavation methods there is no downward force that can be exerted on the underground utilities.
