This proposal from Loughborough University outlines the case to renew the funding for the Industrial Doctorate Centre for Innovative and Collaborative Construction Engineering (CICE) as part of the Industrial Doctorate Centres call aginst the Towards Better Exploitation element of the EPSRC Delivery Plan. In partnership with an established industry base, CICE is delivering a high quality research and training programme that: meets the core technical and business needs of the construction industry; enhances its knowledge base; and produces high calibre doctoral graduates that can drive innovation. The Centre addresses a wide range of research issues that concern the UK construction industry including: Innovative Construction Technologies; Construction Business Processes; Advanced Information and Communication Technologies; Sustainable Design and Construction; and Transport and Infrastructure. Many of these areas have been highlighted in various reviews of the industry including the Latham Report, the Technology Foresight Report, the Egan Task Force Report, and more recently the National Technology Platform's research priorities. It also contributes to the EPSRC Delivery Plan as part of the knowledge transfer research and training activities. The research areas of the Centre align with the Engineering and Science for Sustainability research theme, as outlined in the EPSRC's Research Priorities and Opportunities, and fall under the 'Construction and the Built Environment' and 'Transport' sub-themes. Within the Construction and Built Environment, the Centre builds on existing strengths in the Department of Civil and Building Engineering established as part of the Engineering Doctorate Centre and other related industry based research to address some of the EPSRC research priorities to improve efficiency across the supply chain, including: encouraging the uptake of ICT to promote efficiency; improving building performance to minimise impacts on the environment ; and the analysis and design of civil engineering structures . Within the Transport area Sustainability and Innovation are key themes of the research that centres on transport operation and management, transport telematics, and minimising energy use and environmental impact . The Engineering Doctorate Centre (CICE) was established in 1999 and has subsequently recruited a total of 94 research engineers sponsored by a total of 63 large, medium and small companies. Loughborough University is a research intensive institution, which integrates its research and teaching activity at every opportunity to provide a top quality research led learning experience for all its students. The Department of Civil and Building Engineering has consistently achieved high research rating in the RAE assessments and the last RAE results were 5* in Built Environment. The Engineering Doctorate is part of Loughborough University's excellent doctoral research training programme, which in addition to supporting the pursuit of a particular project aims to provide a basic professional training to support the research and offer personal development opportunities. The training programme integrates taught and research elements tailored to suit the needs of the research engineer, project, and the sponsoring company while maintaining the expected quality of the academic standards required for a doctoral study. The Centre is managed by the Director, Prof. Dino Bouchlaghem supported by a Deputy Director, a Centre Manager and an Administrator. A Centre Management Board consisting of the Director, Deputy Director, and Industrial Representatives meets twice a year and is chaired by a senior industrialist from one of the sponsoring companies, oversees the work of the Centre and provides direction and guidance on strategic matters. This proposal has the full support of the University and has been subject to an internal review process to ensure synergy with the University's Research Strategy.

The project aims to create a prototype multi-sensor device, and undertake fundamental enabling research, for the location of underground utilities by combining novel ground penetrating radar, acoustics and low frequency active and passive electromagnetic field (termed quasi-static field) approaches. The multi-sensor device is to employ simultaneously surface-down and in-pipe capabilities in an attempt to achieve the heretofore impossible aim of detecting every utility without local proving excavations. For example, in the case of ground penetrating radar (GPR), which has a severely limited penetration depth in saturated clay soils when deployed traditionally from the surface, locating the GPR transmitter within a deeply-buried pipe (e.g. a sewer) while the receiver is deployed on the surface has the advantage that the signal only needs to travel through the soil one way, thereby overcoming the severe signal attenuation and depth estimation problems of the traditional surface-down technique (which relies on two-way travel through complex surface structures as well as the soil). The quasi-static field solutions employ both the 50Hz leakage current from high voltage cables as well as the earth's electromagnetic field to illuminate the underground infrastructure. The MTU feasibility study showed that these technologies have considerable potential, especially in detecting difficult-to-find pot-ended cables, optical fibre cables, service connections and other shallow, small diameter services. The third essential technology in the multi-sensor device is acoustics, which works best in saturated clays where GPR is traditionally problematic. Acoustic technology can be deployed to locate services that have traditionally been difficult to discern (such as plastic pipes) by feeding a weak acoustic signal into the pipe wall or its contents from a remote location. The combination of these technologies, together with intelligent data fusion that optimises the combined output, in a multi-sensor device is entirely novel and aims to achieve a 100% location success rate without disturbing the ground (heretofore an impossible task and the 'holy grail' internationally).The above technologies are augmented by detailed research into models of signal transmission and attenuation in soils to enable the technologies to be intelligently attuned to different ground conditions, thereby producing a step-change improvement in the results. These findings will be combined with existing shallow surface soil and made ground 3D maps via collaboration with the British Geological Society (BGS) to prove the concept of creating UK-wide geophysical property maps for the different technologies. This would allow the users of the device to make educated choices of the most suitable operating parameters for the specific ground conditions in any location, as well as providing essential parameters for interpretation of the resulting data and removing uncertainties inherent in the locating accuracy of such technologies. Finally, we will also explore knowledge-guided interpretation, using information obtained from integrated utility databases being generated in the DTI(BERR)-funded project VISTA.

This experimental project will address the problem of wheel track rutting that develops in asphalt road pavements under repeated traffic loading. A new torsional Hollow Cylinder Apparatus will be developed to reproduce, more accurately than hitherto, the field loading regime in the laboratory, so that high quality measurements can be made of the permanent strain that accumates under cyclic loading. Collaboration with the University of California at Berkeley and at Davis will allow use to be made of their established but less accurate asphalt shear testing equipment using identical material. Pilot scale wheel tracking tests will be conducted in the Nottingham Pavement Test Facility to generate rutting performance data and use will be made of full scale test data from the Californian team. The outcome of the project is aimed at improving prediction methods for rut development in asphalt pavements and to assess the reliabilty of a simple practical test for use by industry to estimate the rut resistance of asphalts.
