Recycled glass may help fill potholes

Canada’s crazy climate can wreak havoc with road surfaces, leaving large holes which can damage vehicles and cause accidents. The problem is particularly acute in the province of Quebec where freeze-thaw cycles combine with questionable paving practices to make roads particularly rich in potholes.

Temporary repairs often open up again and there is an on-going search for more permanent solutions. Now, an engineering school with the Quebec University network is going to study using recycled glass in asphalt to try to fill the potholes.

Study to use half of all recycled glass

Researchers will use more than 100,000 tonnes of recycled glass in their study, reports Sarah Leavitt of CBC news. That is half of all the glass which is recycled every year in the province.

Most glass not recycled

This is good news given that people place old glass in recycle boxes but most of it ends up in landfill anyway because the province’s main recycling facility closed in 2013.

A researcher told Leavitt that crushed glass may be good insulating material to prevent frost from cracking asphalt.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.
  9. Radio Canada International publishes contents in five languages. The language used in the forums has to be the same as the contents we publish. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
  13. Posting any type of advertising or call to action, in any form, to Radio Canada International  forums is prohibited.

One comment on “Recycled glass may help fill potholes
  1. If we turned every recycling center in Canada into a Resource Recovery Centre, we can mine the discard stream before anything becomes waste. In Gibsons British Columbia Canada, we’ve been recycling glass for many many years, locally. “Waste as Resources”, the corner stone of how Zero Waste works, turning “lemons into lemonade”.
