How gritting works

The University of Kent’s Landscape Management team are always up early and working hard to keep the campus safe and serviceable for all. During icy weather, they grit the campus roads and footpaths to reduce the risk of accidents to staff, students, and visitors.

What many people do not realise is, there is a fine art to gritting. Timing is everything. If you go too early, you waste the grit, because it lands on a dry road and is blown away by the displaced air as vehicles drive past. If it is raining heavily then it just washes away. Ideally the grit goes down on a damp surface and starts to stick, but if you are too late the surface is already frozen and the salt has to work harder to be effective but it will prevent big sheets of ice forming.

The salt is hygroscopic which means that it attracts moisture from the air and it only becomes activated when it is ‘trafficked’. When the grit is driven over the salt grinds down and mixes with the moisture it attracts and becomes the ideal brine, a salty water, which is when it is most effective.

Similar to how local authorities manage gritting, the Estates department will grit all University of Kent roads and main footpaths before starting on other areas across the campuses. For more information see the University’s Snow and Ice Policy.

Campus Car Parks and Road Updates (26 November – 10 December)

The Transport Team want to make finding a place to park on campus as efficient as possible. To do this, we endeavour to keep staff and students updated on any known car park changes within this newsletter.

At all other times, you can visit our Traffic Management Events Calendar and our Twitter page (@unikent_travel), which are updated regularly.

This section of the newsletter also includes ‘Other Traffic Management News’, to highlight any information that may be of importance to drivers.

Other Traffic Management News

The University Landscape & Grounds Management team have already been out gritting the campus roads and car parks during last week’s frost, and will continue to do so throughout the winter months. Despite their best efforts, car parks, paths, and roads may still be slippery around campus, so please take care when commuting.

 

 

Understanding snow clearing

Snow ploughs only work effectively when snow is more than 5cm (2inches) deep. If snow fall reaches this level, Grounds Maintenance will use a combination of snow ploughs and other methods to clear the snow as snow ploughs cannot go over road humps or similar traffic calming measures.

Grit does not melt snow and therefore grit cannot be applied on top of deep snow. Refer to understanding gritting for more information on how gritting works.

Similar to how local authorities manage snow clearance, the Estates department will aim to clear all University of Kent roads and main footpaths before starting on other areas across the campuses. Please refer to the University’s Snow and Ice Policy for more information.

Adverse weather- plan your journey

As the weather starts to get colder, please ensure you are familiar with the University’s ‘Pay during periods of severe weather conditions/ major transport disruption’ policy and procedure to understand what to do during adverse weather. Remember that weather can change at any time. Be prepared for this before you start your journey.

Where possible the Transport Team will tweet from @unikent_travel with travel information.

Driving
Ensure that you and your vehicle are prepared for driving in adverse weather conditions. Read some top tips to prepare for driving during the winter and don’t forget to plan your journey before you leave so you are aware of any disruptions.

Public transport, cycling and walking

  • Plan your journey, check if there are problems on public transport or local roads
  • Delay your journey, if possible, to allow temperatures to rise and ice or snow to melt
  • Avoid footways in the shade. It takes longer for ice or snow to melt in the shade
  • Always wear appropriate footwear and reflective/bright clothing
  • Ensure that you have a torch or lights so motorists and others can see you when walking or cycling
  • Plan your journey and be prepared for times of adverse weather.

Understanding Gritting

Timing is everything. If you go too early, you waste it, because it lands on a dry road and is blown away by the displaced air as vehicles drive past. If it is raining heavily (like yesterday afternoon) then it just washes away. Ideally it goes down on a damp surface and starts to stick, but if you are too late the surface is already frozen and the salt has to work harder to be effective but will prevent big sheets of ice forming.

The salt is hygroscopic which means that it attracts moisture from the air and it only becomes activated when it’s ‘trafficked’. So when it’s driven over the salt grinds down and mixes with the moisture it attracts and becomes the ideal brine, a salty water, which is when it is most effective.

Estates staff have all been working hard to ensure that the University can continue to operate during these adverse weather conditions. Please be aware that Canterbury campus is over 300 acres and has many walkways, steps, roads, car parks, accessible ramps and cycle routes. Similar to how local authorities manage gritting, we grit these areas according to their priority as not all areas can be covered at all times.

We would like to thank Grounds Maintenance at Canterbury campus and FM team at Medway campus for being on site last night and the early hours of this morning to make sure the priority roads and footpaths are gritted.

Snow and ice- Canterbury and Medway campuses

At Canterbury campus Grounds Maintenance, Estates, have gritted priority roads, pathways and car parks throughout the night and this morning.

At Medway campus gritting contractors and the Estates FM team have gritted priority roads, pathways and car parks this morning. Access roads to Dockyard buildings are clear as Chatham Historic Dockyard Trust have gritted the roads onsite overnight and the Estates FM team have gritted the entrance to the buildings this morning.

Please drive carefully and take extra precautions when walking to and from your vehicle and around campus as some areas may still be slippery.

We recommend you check traffic news or your transport provider for travel updates during this adverse weather. Visit www.kent.ac.uk/transport/planning  for useful links to transport (and road) twitter accounts and service updates webpages.

We are also trying to tweet some travel updates from our @unikent_travel twitter account, which can also be viewed online at www.kent.ac.uk/transport/news
