Nine asphalt plants received the 2013 Trillium Awards

There were nine asphalt plants that received the 2013 Trillium Awards recently, as well as four other plants that were recertified at this year’s Ontario Hot Mix Producers Association’s (OHMPA) annual Fall Asphalt Seminar on Dec. 11.
The award recognizes the best in asphalt production and requires recipients to meet a set of standards in seven categories: appearance, operations, environmental, safety, permitting and compliance, community relations and industry participation.
The nine awards went to Aecon Construction & Materials (Brampton, Goderich and Orangeville plants), G. Tackaberry & Sons Construction Co. (Tackaberry asphalt plant), and The Miller Group (Lavis Contracting Co. Holmesville asphalt plant, Mill-Am asphalt plant, The Murray Group Murphy and Bowman Pit plants and Smiths Construction, Turcotte Pit). The recertified plants were The Miller Group’s E.C. King, Sydenham asphalt plant and New Liskeard, Port Colborne, and Whitby asphalt plants.
“The asphalt industry works hard to make itself a good neighbour and a steward of the environment,” said OHMPA executive director Doug Duke.
“The award was created to recognize those plants that go beyond the ‘gold’ standard already required by industry regulations.”
There are total of 55 plants that have received the Trillium Award along with 35 recertified plants.
The Dr. Norman McLeod Award for Innovation in Road Building was also handed to Lye Moran, asphalt team leader for Imperial Oil’s Sarnia Research Centre.
Moran’s asphalt research has led to breakthrough’s recognized by 12 patents.
The first ‘Bleeds Black’ Awards, which highlights an individual’s commitment and passion toward the industry, were handed to University of Waterloo’s Centre for Pavement and Transportation Technology director Dr. Susan Tighe, Walker Aggregates Vineland Asphalt Plan foreman Mark Cosby and OHMPA technical director Sandy Brown.

a $10 million upgrade to DAYU asphalt plant

DOWNER Infrastructure took a significant step towards a greener future with the opening last month of a $10 million upgrade to DAYU asphalt plant(www.asphalt-plant.cn).
The integrated manufacturing facility will be the first on the Sunshine Coast to be able to produce warm mix asphalt.
Warm mix was produced at between 120 and 140 degrees, instead of the traditional hot mix temperature of 160 - 180 degrees.
That means there is less energy used to heat the asphalt and that means reduced carbon emissions.

"The other real positive is the benefit to the work crews and pedestrians, as it is safer."
The plant will conduct its first warm mix trial early next year, primarily for key clients in Main Roads and the Sunshine Coast Council.
This asphalt plant upgrade eventually is for all our asphalt to be warm mix and we can also recycle current roads out of this facility.
We take the profiles currently on the roads back to the plant. They then go through a process and we can reuse that material. We know the council is particularly driven towards an environmental and sustainability future, so we thought it was a great opportunity to pave the way for a greener future. and the upgrade would likely mean more jobs as the volume of work increased, promoted economic development.

What is the hot mix plant control system?

Programmable controller as the core of hot mix plant control system, to complete the boot of asphalt equipment, ingredients and various working during transport. whole equipment control system composed by feeding, ingredients and transportation each of these three parts independently of each other. Each section has two operating modes, manual and automatic. IPC and touch screen have the function, that complete the main process parameters, workflow display and alarm output of the equipment. IPC also has these function that production data automatic archiving, production statistics queries, improve of the report output. to meet the job requirements of asphalt mixing equipment, according to the requirements the system is configured automatic and manual intervention in two ways, for operators provides a convenient in the commissioning, production preparation and different ways of working, such as normal production.The manual type: through the console buttons the poerator complete manually production or troubleshooting emergency maintenance .

The automatic type: PLC as the core, avariety of sensor, limit switches, and each loop feedback signal as collected objects, through the PLC's digital output module control device startup,ingredients mixing transportation and other automated production process.
Oblique trolley adopt inverter control, use rotary encoder to variable speed and positioning control, make the trolleys run more smoothly. And has overrun limit switch, so that the trolleys running more secure.
baghouse dust collector adopt pulse cleaning dust, circuit board to control the pulse valve job to make bag cleaning. For the baghouse inlet temperature set a protection device and cold wind door, the opened size of cold wind door decided by the baghouse inlet temperature, to adjust the baghouse inlet temperature, and to ensure continuous production. another ,the baghouse dust collector set a baghouse over-temperature extinguish fire device, that can be set the high temperature limit value according to the baghouse use temperature, when the baghouse inlet temperature exceeds the high temperature limit value, the burner is automatically turned off to protect the bag.aggergate drying system adopted Liaoyuan group(www.lyroad.cn) burner, equipt liaoyuan group muffler, low noise, and improved fuel lines, automatic cycle circuit before ignition, automatic purge line after the cease-fire, the direct use of heavy firing, user-friendly. hot aggregate temperature control have manual and automatic two ways, when ignition use manual control, when the hot aggregate temperature stability switching to automatic control, in automatic mode, the temperature control precision high stability, without operator intervention, convenient operation.
At the top of the three reservoirs silo installed level meter, when the storage bin is full, then the audible alarm. on the powder silo wall installed vibrator warehouse wall, when detected powder stick stuck atop vibration vibrator can take it down.
Five hot silo and bunker adopted continuous level meter, so that the operator can more accurately understand the thermal material and power reserves, in order to adjust the feed rate.In the fine cold aggregate positions with a broken material detection switch, for cold aggregate timely detection alarm and timely processing. At the site has an cold aggregate emergency stop button. In the operating table, set the "emergency stop" button, the occurrence of unforeseen circumstances, can press this button, the entire equipment downtime.

Prep work for 'Fortify' asphalt plant to begin Monday

Prep work for 'Fortify' asphalt plant to begin Monday
RALEIGH, N.C. — Lane closures associated with the North Carolina Department of Transportation's Fortify project will continue next week on Interstate 440 East between the Sunnybrook Road underpass and the I-40/440/U.S. Highway 64 split. 

Crews will close the lanes between 9 p.m. and 5 a.m. Monday through Wednesday, with the start time of work remaining flexible based on traffic volume. Work could be delayed until as late as 11 p.m. on each night if traffic is heavy. 
The closures will allow crews to begin setting up barrier walls along both shoulders for the construction of an asphalt plant that will be used during the project.
The plant, which will be located in the median, is designed to increase efficiency and safety during the project and keep crews from needing to truck in materials from plants outside the work zone. The asphalt plant should be completed sometime in the next four to six weeks, officials said.
Daytime closures will begin in early December, and the 2.5-mile section of I-440 that is part of the rebuild will be complete by late 2014.
Crews will then move to I-40, with daytime lane closures beginning late in 2014. The entire project should be complete by the fall of 2016, DOT officials said.
