Beijing will start building the first of the "sky train" low noise and speed of 60 km

Beijing's first monorail line (sky train) - Yuquan route is expected to start this year, opened to traffic in 2015.Yesterday, the railway Academy website carried out the EIA publicity about Yuquan route and published along 21 site name. 
Low noise, through the town without disturbing
"The Beijing authorities are organizational learning advanced operating experience and experience in building traffic ohter cities in the world, to begin studies in urban areas, especially in the city center connected to the region, set up a similar "sky train" the monorail, slove the subway construction restricted problem in some areas". In two sessions this year in Beijing, The Chairman of the board of the Beijing Railway Construction and Management Co., Ltd., Wu Hong Jian said.
The Beijing track Yuquan route just is a contact line southwest of the city center in the line network, which is positioned as the volume level of the line. Line starting at the Shijingshan longevity Ridge, ending the fengtai and stepping, along the series a large living and features area such as Zhongguancun,Shijingshan Park, Badachu, Yuquan Road and residential areas along Xiaotun Road, Fengtai Science Park, service in the center of the city periphery, play a role that modulate the central city passenger rail network balancing.
"Subway construction in the city, the noise problem is a big problem, all along is the built-up area, not by the EIA. Compared with the sound of when through the city's light rail vehicles in the present, the monorail line with the rubber tires, the noise is very low.", Wu Hong Jian believes that.
Line intends this year to start operation next year
According to the China Academy of Railway Sciences website about the Yuquan route project EIA publicity, which is the city's first launch of the monorail. The line from the YongYinQu North Road intersection with the northeastern side of the JinDeng North Street on the north side, located along 21 stations.
Currently, Yuquan route passenger flow forecast by the experts. For the Beginning, recent and long-term the passenger-scale, full-day and morning and evening peak hour traffic section, each site traffic flow, and along the route of stations passenger flow were predicted.
"the project started in 2014, was opened to traffic in 2015, the total duration of 2 years.",According to EIA publicity revealed.

Kokomo repaire the pothole use a application but not as good as hot mix asphalt

Kokomo will have to stick with cold-weather pothole repairs for now, as the city’s asphalt supplier, E&B Paving, has no plans to open early.
Kokomo Mayor Greg Goodnight, who once worked on a road patch crew himself, thinks it’s possible Indianapolis, a city of 835,000 residents, found a way to make it financially worthwhile for one of the Indy-area asphalt plants to open up.
They use a hot application, which helps, but Dayu company pointed out that it’s not as good as hot mix plant.
For the time being, asked the city street department to work two shifts on pothole duty, until some of the damage from the brutal winter can be repaired.
The city’s method of heating cold patch material and the warm-weather use of hot mix both have their advantages, depending on current weather conditions, according to city officials and E&B Kokomo sales manager Kip Chandler.
The brief mid-week warm-up may have offered a small window to apply hot mix down in Indy, but freezing temperatures are predicted for the weekend.
Applying hot mix when the cycle of freezing and thawing is still going on can be counterproductive.
They have to have the right weather conditions to prep the pothole for a hot mix patch, so it doesn’t pop out in the middle of the winter.
E&B typically opens its asphalt plant around the first part of April, because that’s when the hot mix it produces can be effectively used, both by city crews and by E&B’s own workers.

To prep a pothole for hot mix, crews typically use an air compressor to blow any debris completely out of the hole, and then put down “tack” — a binder — then the hot mix, and then use a roller to compress it.
If the temperature of the road surface is too low, the hot mix won’t compress properly, and if it snows, there’s a likelihood the snowplows will pry the patch out.
The staff also pointed out that the hole itself needs to be dry and stay dry while the hot mix cures.
Obviously, with the snow melt, it’s not going to be dry anytime in the near future.
That’s why city crews use cold patch material, either cold or heated, during the depth of the winter.
People ask us about this all the time, but there’s a lot of factors which go into the decision. The guys with the city do a great job in determining which materials they use. They work together very well.
Interestingly, under some conditions, the repairs made with heated up cold patch material can end up being more or less permanent, as the material compresses into place.
But larger potholes, the kind of yawning chasms which flatten tires and knock tire rims and alignments out of whack, eventually require hot mix repairs.
You haven’t seen anything around here that looks like it can’t be addressed with cold mix. “It’s Indiana. We deal with these conditions every year.”

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.
