The National Asphalt Plant Association Promote sustainable development

The National Asphalt Plant Association(NAPA) has announced that asphalt plants earning its Commendation now have an option to pursue a Star Achievement Sustainable Commendation.

The expanded commendation requires asphalt plant operators to understand the use of recycled materials, to quantify and control energy use and emissions, and to articulate a corporate sustainability plan. NAPA says these steps are part of the process of assessing “the social, economic and environmental efforts of an asphalt production facility to gauge how well it puts the principles of sustainability and community engagement into action.”
NAPA’s Star Achievement program was created in 1999 to recognize asphalt plants that met or exceeded national best practices for operations, environmental practices, safety, permitting and regulatory compliance and community relations.
“The Commendation program encourages continuous improvement,” says Bill Ensor, NAPA chairman. “It is a way for asphalt plants to benchmark their operations, and it provides a blueprint for how to improve them. With the Star Achievement Sustainable Commendation, plants that are already good, conscientious operations will have new guidelines to make their facility an even better neighbor.”
In addition to recycling, emissions and energy, the new commendation also covers issues ranging from noise and light pollution to volunteer programs. Plants must first qualify for a Star Achievement Commendation before seeking the new commendation.
The 2014 Dayu Asphalt plant Commendation will begin accepting applications, including its new Achievement Sustainable Commendation, on April 1, 2014.

DEC found a host of stormwater after asphalt plant at Stewart International Airport

The state Department of Environmental Conservation found a host of stormwater, housekeeping and record keeping violations last month at the temporary asphalt mixing plant(www.asphalt-plant.cn/mobile-asphalt-mixing-plant.html) at Stewart International Airport.
Jointa Lime, the upstate New York company that runs the plant, had to immediately respond to some of the violations, removing asphalt sediment from a tributary of Beaverdam Lake and Moodna Creek, according to a copy of the letter the DEC sent the company.
The company addressed other problems at the site by conducting employee training and moving stockpiled materials off site, according to a letter it sent the DEC.
Jointa Lime officials did not return calls seeking comment.
Before the discovery of the violations, the asphalt mixing plant had already drawn the ire of the Stewart Park and Reserve Coalition, an environmental group concerned about pollution, traffic and noise from the plant. SPARC, led by President Sandra Kissam, claimed in a lawsuit against the Town of New Windsor and Jointa Lime that the town allowed the temporary plant to be built without proper site plan and environmental review.
The plant, located on Town of New Windsor property, began running in July, and will likely continue for another year-and-a-half. The asphalt made at the plant is used to repave the runways at Stewart.
The Town of New Windsor made a motion to dismiss the SPARC lawsuit last month, said Steve Gaba, an attorney working on the matter.
"It's without merit," he said.
Gaba said that municipalities can judge whether or not projects to be built on their land need site plan review. He said in this case, New Windsor made the appropriate decision. The town did perform an environmental review under the State Environmental Quality Review Act.
New Windsor Town Attorney Michael Blythe said he knew of the violations at the plant, and said that the town told Jointa Lime it anticipated the company would immediately correct the issues.
SPARC made the initial complaint about a violation at the asphalt plant, Kissam said. She and Jay Westerveld, an Orange County environmental activist, observed the plant from the road, and noticed that there was some material breaching a silt fence.
"He said, 'That's definitely a violation, Sandra,'" Kissam said.
The pair snapped a picture and sent it to the DEC, which later followed up with an unannounced site visit.
Kissam said the violations prove that the plant needed a more thorough review than what it originally got from New Windsor.
"They were irresponsible to pass the asphalt-plant on without the necessary review," she said.

Asphalt Mixing Plant Try Mixing

Asphalt Mixing Plant(www.asphalt-plant.cn/mobile-asphalt-mixing-plant.html) try mixing is a process through mixing determined production mix, mixing time, and mixing quality inspection.
Determination of the production mix: the laboratory design mix is determined through the aggregate sampling , drying, sieving, but the device only two layer and four kinds of specifications of the screen, can not install the lab so multi-layered screen, therefore , after determined the theoretical mixture, the case should be combined with screening devices determine the production mix. After drying the required aggregate screening , into four hot silo , then material sampled for the four aggregate bin. First a certain amount of material to be sampled into the mixing tank , let go after mixing , discharged into the waste aggregate bin , and then take about 200g or so of the material input mixing tank , into unloading car , unloaded mixing into the hand car wiht manually way, If overflow material from small trolley should removed feed cap portion, so as not to affect the test results of material segregation . according to the taken four kind of hot aggregate screening results to determine the percentage of various mesh intervals , then determine the production mix .

Asphalt mixing plant mixing time determination : after determined the production mix , began mixing asphalt mixture, and determined mixing time , mixing asphalt materials , not even with the naked eye observation of mixing is uniform , there should be laboratory quality test indicators to determine. The beginning , mixing time may be longer, by continuous sampling , the stability of each sample and the flow of the discrete values of other indicators should be more than 5% , and then adjust the time to maintain the quality.
