Once again a group of intrepid swimmers met at the RAC Club, Epsom to raise money in the Inter Livery Swimathon together with 17 other Liveries. Each team of five had to swim 5000 metres. We were slightly oversubscribed so Paul Dunkley found himself swimming in the Chartered Surveyors’ Team. (As he said, it was the first and he hoped, only time, he has been called a surveyor!) The Pavior’s Team was made up of Elaine Cordingley, Jan Steward, Miles Ashley, ace swimmer Keith Lambert with Tom Barton. The team completed the challenge and for a change were not the last in the water so there was time for a well earned drink before Dinner. This year we have raised circa £10,500 in sponsorship and the money is to be split between the Lord Mayor’s Charity, The Treloar Trust and the Tom ap Rhys Pryce Memorial Trust. Our thanks go not only to the swimmers and their supporters but more importantly to the many very generous people who supported us. Tom Barton |

Philip Boothroyd of the University of Nottingham has been in receipt of a Paviors’ Bursary since he arrived to study at the Nottingham Centre for Pavement Engineering (NCPE) in 2004 following graduation from the University of Bristol. His interest in pavement engineering was developed while studying at the Universitá di Perugia in Italy and he is now carrying out a project looking at the assessment of industrial by-products with respect to their potential for groundwater contamination. Under current practice, the system of assessment is based on that used for of landfill sites. A series of standardised leaching tests are carried out on the relevant materials in accordance with established EU or UK test procedures. Limiting values are imposed on the concentrations at which contaminants are released during these tests and the total amounts of each contaminant which are released. If these limits are exceeded, the material is deemed unacceptable. This method of assessment is being questioned, however, as it only considers the material itself and not the other environmental factors or the purposes for which it is being used. In reality, there are already contaminants in the highway environment and the capacity of the material to adsorb these may be a more significant measure of their impact on ground water quality. The reaction between pavement materials and contaminated run-off is being assessed using modified leaching tests in which the solvent is replaced with a pseudo-runoff. Subsequent analysis of the results should help to identify whether there is likely to be a net adsorption or release of contaminants by the materials if they are used in the construction of a pavement. The Paviors’ Bursary is assisting in this project by contributing to the Philip’s stipend and the cost of test materials and equipment. Stephen Brown |
