The Standards Advisory Group has been established to assist CIHT to co-ordinate and promote the activities of the Institution in relation to standards advice for materials and pavement design for highways, airfields and industrial purposes. Members of the group sit on a number of British Standards Institution (BSI) Committees developing standards for the industry.
CIHT are seeking to establish a core group of members who are interested in receiving alerts and/or assisting the Institution in our relationship with BSI and developing standards. If you would like to be involved please contact email@example.com
BSI has also recently launched a public online system where new work proposals are accessible for wider view and comment. This is designed to increase awareness of the Standards Development Portfolio. CIHT members may wish to put forward comments through the CIHT and its representatives or simply as a member of the public.

CIHT member wins Wolfson prize
Well done to CIHT graduate member, Gergely Raccuja, who works for Amey as a transport planner, on winning the £250,000 Wolfson Economics Prize. Gergely beat four other finalists in the competition to find ways of paying for better, safer and more reliable roads. Read more here.
CIHT Foundation prize awarded
Congratulations to Max Harwood, recent winner of Newcastle University’s CIHT Foundation Prize. Max received the prize as the top undergraduate Transport Option Engineering student at the university this year. Max was presented with the prize at his graduation ceremony last week by North East & Cumbria Chair Darran Kitchener. If you would like more information about the CIHT Foundation click here.
Have your management skills recognised
CIHT has partnered with the Chartered Management Institute (CMI) to offer a streamlined route to qualify as a Chartered Manager (CMgr). The partnership means that CIHT members who hold CEng, IEng, or TPP registration with five years or more of management experience are eligible for CMI’s qualified route to becoming a Chartered Manager. Eligible CIHT members receive a 50% discount on the CMI membership fee. To find out more information click here.
Interim registration is available to those who have obtained the academic base for either IEng or CEng, but do not yet possess the relevant practical experience to meet the competency requirements for full registration. Having interim registration will demonstrate to employers your enthusiasm, drive and commitment to both your career and the profession. For more information, click here.

Background to M11 Asphalt Reinforcement Trials
The results show the 20-year predicted traffic loading in lane 1 and lane 2 to be 83msa and 19msa respectively.
Contractor and design life
The successful contractor was La Farge. The design life requirements for the trial section are 20 years.
Programme of works for trial area
GridSeal® trials of 210linear metres (936sq.m.) were installed between chainages 2990 and 3110 on the M11 Southbound Junctions 10 to 9 in the early morning of Thursday 8th November 2007. The installation commenced at 12.00am and finished at 12.31am.
Present during laying by Asphalt Reinforcement Services were Howard Cooke and Ian Walker of ARS and Chris Sullivan of Material Edge Ltd. Also in attendance were TRL representatives.
Treatment in the Hard shoulder was not part of the trial. The surface was planed down 60mm and 25mm of regulating was put back followed by 40mm surface course.
Treatment in Lanes 1 and 2 GridSeal® trials
The weather throughout laying was dry and cool (about 5°C), the surface was swept clean using wet and dry vacuum road sweepers.
Plane off 110-115mm of existing asphalt leaving about 30mm over the CBM and sweep clean. Replaced with:
During laying the chipping lorry damaged a small 1m x 2m section of the GridSeal® resulting in an area of pad coat and GridSeal being removed and replaced by hand. This was located in the centre of lane 2 at Chainage 2990. The repair was installed to the satisfaction of those supervising.
Otherwise there were no observed difficulties in installation over subsequent overlaying of the GridSeal® system.

The use of asphalt to generate solar heated water to defrost roads is an excellent subject for NCE to bring to the attention of your readers. In addition to the TRL trials using soil as the medium of storage (Trials begin on salt free road de icing system NCE last week) there is already a commercially available system being used in The Netherlands which utilises ground water in aquifers for storage of hot and cold water.
The first 2 Road Energy System® projects (as the Dutch process is called) in the UK are now imminently being constructed in Scotland by a soon to be signed UK licensee. A national surfacing contractor has also expressed interest in the system which utilises low temperature polymer modified asphalts to avoid melting the European patented plastic pipes and retaining grid system.
Undoubtedly interest will continue to grow when people fully realise the scope for generating heat and cold from asphalt pavements.
The Road Energy System® was developed jointly by a multi discipline engineering team comprising Ooms Avenhorn Holding (contractor), Tipspit and Vloerverwarming as a method for heating and cooling buildings. Following this process the ‘waste’ warm and cold water still has sufficient energy to defrost in winter roads, car parks, ramps, flyovers, aircraft standing and taxiways etc as well as cooling them during summer, thus prolonging the life of the pavement into the bargain. The system has successfully passed through extensive trials and developments over the last 8 years to reach major scheme status. The largest project to date at 10,000sq.m. is a flyover into Rotherdam docks where defrosting of the elevated structure is key to ensuring year round access.
Now that authorities and clients are looking to new housing, airport and industrial developments to be carbon neutral in terms of environmental impact the Road Energy System® provides a viable proven solution to low energy heating and cooling of buildings. Forward looking councils like Dundee have already identified schemes where the system maybe used in future. Airport authorities have also expressed interest with acres of black surfacing to utilise for collecting energy, which also require defrosting in winter, and large terminal buildings to heat and cool.
With NCE’s talent to reach the masses we would be delighted to show your readers real European cooperation involving multi disciplined engineering teams on UK based working projects in the near future.
