12 Profile Arthur Hannah Editorial 14 Education & TRAINING SPECIAL Education – The need to develop This is my last edition as editor before I hand over the baton to Pippa Birch. I have Training in the Irish Branch enjoyed my time as editor and Chairman of the Publications Committee and have Continuing Professional Development (CPD) seen numerous changes in that time. When I took on the roles we were running a ‘You can go and sit in the soils cupboard!’ 2 colour Asphalt Professional, which was 1 step forward from the News Letter and the Yearbook. One of the early decisions was to make Asphalt Professional the 25 Diary ‘flagship’ publication and to go to full colour on high quality paper. In order to achieve Events this we discontinued the Yearbook and published the first really professional looking journal in March 2006. This was very well received and we continued in this format 26 Institute News until January 2010 when we changed to an on-line publication. This decision was not Scottish Branch News taken lightly and was not the most popular decision but at that time it was the only 28 Conference Report choice, on financial grounds, if we were to continue with any publication at all. The Many and Varied Uses of Asphalt We did however restore the Yearbook in 2011 so that the membership received at least 1 publication a year. 32 Publications New Texture Depth and PSV requirements As you will already know this is now the second edition back in print as well as bought in by the Highways Agency as available on-line and with the Institute on a firmer financial footing we hope that this will continue for many years to come. I am pleased that I have been able to finish my Interim Advice Notes stewardship of the Publications Committee on a positive note and give my successor 33 Jean Lefebvre (UK) Limited something to build on.
Pippa has been the Assistant Editor for a number of years now and has slowly 34 The Social Whirl become more involved over that time. I know she is full of good ideas about how she would like to see Asphalt Professional progress and I wish her all the best in moving it onto the next level. 35 Institute Update Publishing Asphalt professional has always been a team effort so it is important for Pippa that she can get some help now that she is editor. We have had some offers of help but it is a case of never having too much. So if you feel you can help with proof reading or acquiring technical or then article then please let her know, it will all be gratefully received.

February 2013
The first 2013 technical meeting of the branch took place at the regular venue near Frome of the Fox and Hounds, Tytherington on 13 February 2013, where about 27 people gathered to hear from Joy Jones, HM Principal Inspector from the Construction Division of Health & Safety Executive (HSE) on the subject of corporate manslaughter. However, there was uncertainty about whether the talk would Joy explained that everybody (directors, managers, actually go ahead because Joy only arrived at employees and the self-employed) have a duty to the time that it was due to start, having got lost anyone affected by their work, including themselves, leaving Bristol where she had been visiting her son for Health and Safety.

A Landmark in Training EMISSION REDUCING CO2 SAVINGS In celebrating its 40th consecutive year, the MPA / Newcastle University Asphalt Materials WITH IN-SITU and Flexible Pavements Course clearly demonstrates that it remains at the forefront of RECYCLING training and education in the sector. In that time, literally thousands of delegates have attended, participated and we believe enjoyed, the unique opportunity to learn about a broad range of topics and issues relating to highways construction and maintenance design, materials, processes and innovation. Based on delegate feedback, the content and speakers are reviewed every year in order to meet the changing needs of the sector and by doing so keep it fresh and relevant. The friendly atmosphere and opportunity to meet with other delegates from a wide range of highways-related activity and expertise also provide a special networking opportunity for delegates and contribute to the ongoing success of the Course. Past delegates include representatives from across industry and the client sector, many of who now hold significant and high profile positions in their organisations and remain their own best advert. The need for well trained and competent personnel in the sector has never been higher, so take this landmark opportunity to inform and educate yourself and / or your staff. Clearly budgetary pressures are also higher than ever in all businesses but the Course remains excellent value which the acquired knowledge can pay back many times over.

Education and training special
The Institute of Asphalt Technology was founded in 1966 as a Learned Society by a group of far-sighted practitioners in the belief that there was a need for sharing technical information, educating new people into and within the Industry and for setting and protecting standards across the Industry. This belief has not changed in the last 47 years and the Institute prides itself on offering comprehensive training programmes, CPD, technical articles and technical events for it’s members. In this issue of Asphalt Professional, we explore the current educational offerings for our members, find out about some of the initiatives taken by our branches and look to the future.

The branch realised that this shortfall in training The course was developed by an IAT working group could be made good by tapping the knowledge of following detailed discussions with both the private experienced members, practitioners and specialists and public sectors on the perceived training needs from home and from overseas. The training was of technicians and inexperienced engineers. The carried out as lectures and through workshops, result was a Training Course on Road Materials, seminars and conferences. The branch engaged Maintenance and Construction Techniques. with engineers and technicians from non IAT Through the good offices of the NRA, we joined members in construction firms, material suppliers, forces with a local authority regional training centre with consultants, academics and especially with in Co.

Grip Tester Mk 2 The measuring axle is linked to the recording wheel by gears which causes a braking effect on the measuring axle which can then be measured as a “Grip Number” . Values of Grip are then factored to produce an equivalent SCRIM value. SCRIM values are referred to in the Design Manual for Roads and Bridges. The test wheel in the SCRIM apparatus is set at 20o to forward travel. This wheel configuration creates a pressure on the wheel related to the skid resistance of the surface and measurements are taken at 50Km/hour. Grip Tester Calibration procedures are carried out before every test, consistency checks are recommended to be carried out on a well characterised pavement every Stuart reported that tests carried out on 6 year 4-6 weeks.

He showed how controlling surface water run John Cook provided a presentation which explained off at source through the use of pervious surfacing some of the key functional requirements and materials such as porous asphalt can help to mitigate technical issues in airfield pavement engineering flood risk and improve water quality. Porous asphalts, and the current construction practises for asphalt such as Bardon DrainAsphalt, have been developed surfaces on MoD airfields. In order to meet various specifically for use in SUDS applications to provide a airfield specific challenges, Mr Cook described the draining surface layer. These materials are produced key initiatives and recent developments that are using a polymer modified bitumen combined with being undertaken by the MoD.

Each location had specific requirements and delegates were introduced to each The presentation given by Tim Freeman introduced bespoke material that was designed and produced delegates to the use of asphalt in sports construction for those locations. – where it is used, how it is installed and tested and future developments. The development of artificial surfaces over grass offer many positive attributes, sometimes allowing higher standards of performance by players – it has become the only option for some sports, such as hockey. Mr Freeman explained about installation methods for asphalt surfaces, which generally have limitations on the use of large items of equipment. He described the properties Rockingham Racetrack - UK required for an asphalt surface, such the friction, energy restitution and topography, as well as the City streets (an alternative aesthetic asphalt) tests required. Sports surfaces are usually specified Chris Marchesi, Aggregate Industries on a performance basis rather than to BS or BS EN In the final presentation of the day, Chris Marchesi standards. introduced us to a product used as an alternative to coloured asphalts, clear asphalts, high friction surfaces (HFS) and granite setts. This material consists of a stone rich mix that uses aggregate selected for its visual appearance as well as its engineering properties. Once the material is laid using conventional techniques, the bitumen is removed from the surface by shot blasting thereby exposing the colourful aggregate within the asphalt.
