BIOREPAVATION: Innovation on bio-recycling of old asphalt pavement
  • Funder: INFRAVATION RESEARCH PROGRAMME 2014.
  • Total value: €1.500,000, €200k at UNOTT
  • Start to end date: 2015 - 2018

Summary: 

The overall goal is to provide the opportunity for road authorities, or more generally for countries with mature networks, to be self-sufficient in materials via “  BioRePavation” using bio-products locally produced and used along with asphalt pavement recycling. The main scientific and technical objective is to prove that alternative binders can be used to recycle asphaltic pavement with the same level of performance in comparison to conventional solutions with petroleum bitumen. To do so, the research team proposes to build a demonstration where three innovative pavement solutions using bio-materials will be tested using an accelerated pavement testing facility.

CRABforOERE - Cold Recycled Asphalt Bases for Optimised Energy & Resource Efficient Pavements
  • Funder: CEDR TRANSNATIONAL ROAD RESEARCH PROGRAMME under the call 2017
  • Total value: EUR 647.894
  • Start to end date: Sep 2018 – Sep 2020

Summary:

As an alternative for hot recycling, the use of reclaimed asphalt (RA) in cold recycling materials (CRM) is applied internationally with success. Also, in Europe (especially Italy and the UK) significant proportions of incurred RA are already cold recycled by application of foamed bitumen, bitumen emulsion and/or mineral binders. Good experience regarding mechanical properties and durability was further made with CRM for recycling of tar-contaminated pavements, for example in Germany. Generally, RA contents 75 % are reached within CRM. In France, annually ~1,5 mil. tons of cold asphalt mixtures based on natural aggregates and bitumen emulsion are applied since decades in base layers. Due to the mix preparation at ambient temperature, CRM demand for comparably less energy. Therefore, Cold recycled asphalt bases (CRAB) can be considered as pavement of optimal energy and resource efficiency (OERE).

Within CRABforOERE project, the experienced long-term performance of CRAB structures is assessed for various climatic conditions via Europe. From the results, mix and pavement design procedures are validated. Further the RA will be assessed as the aggregate part of the CRAB materials by concentrating on the relevant properties rather than for its application in hot asphalt. The CRAB structures will be assessed in terms of sustainability. Finally, the construction of three test pavements will be scientifically accompanied. On these structures, short-term curing performance will be assessed by monitoring the water content. Further, these structures will allow for follow-up assessment of long-term performance.

MORPHINE (Re-designing the coast: The Morphodynamics of Large Bodies of Sediment in a Macro-tidal Environment)  

Funder: EPSRC

Dates: April 2016-April 2020.

Value: £395,333

Partners: University of Swansea.

Summary:

We are developing a mathematical description of morphodynamics as it pertains to a macro-tidal environment (coastal region with large tidal range, like that in the UK), so as to understand the movement of large deposits of sand on our beaches and shorefaces (shorefaces are, loosely, the regions in between the beach and the continental shelf floor). 

This theory will allow us to formulate a new mathematical modelling approach. These models will allow us to develop a new approach to designing sea defences, in which large quantities of sand ("nourishments") are deposited at strategic locations at and / or near to the coastline. These nourishments will provide a source of sediment for beaches that are eroding, but, importantly, they will also alter local wave and current conditions, which will transform previously eroding beaches into more stable configurations, and so form naturalistic coastal defences. 

Theory and models, coupled with a new, realistic statistical model of sea conditions, will make it possible for us to predict the behaviour of these nourishments to a reasonable degree of accuracy under different conditions, and with good efficiency. This will support the design sea defences that do not have to rely on invasive, expensive and reactive traditional sea defences. 

The work addresses UK conditions in particular, in which a very large tidal range combines with a wide variety of wave conditions to produce a particularly challenging environment. We are therefore proposing to undertake fundamental work on coastal morphodynamics so as to develop tools that will let us re-think our coastal defence strategy.

Pavement LCM - A complete package for life cycle management of green asphalts
  • Funder: CEDR TRANSNATIONAL ROAD RESEARCH PROGRAMME under the call 2017
  • Total value: EUR 562.689
  • Start to end date: 2018 – 2020

Summary:Life Cycle Assessment (LCA), Life cycle costing (LCC) and Social Cost Benefits Analysis (SCBA) are becoming popular techniques aimed at helping the different stakeholders in the process. However, the lack of a standard framework to perform Life Cycle Management (LCM) of road infrastructures means decisions are very much dependent on the analyst‘s work and assumptions, which can lead to considerable differences amongst methodologies and finally makes results incomparable from one case to another. PavementLCM is a 2 year international project which will be carried out by a multi-sectoral consortium to deliver a complete package to allow NRAs to carry out harmonised LCM exercises and durability assessment for Green Asphalt, as well as providing training and user-friendly guidelines to support their widespread use.

Resilience of a Himalayan Road Network

Funder: EPSRC – Global Challenges Research Fund

Total value: £12,000

Start to end date: 2017 - 2018

Summary:  Due to its orography and recent history, Bhutan’s transportation network is extremely limited. Most road links don’t have alternatives. Almost all are very lengthy, tortuous and, consequentially, operate at low speeds (c25 km/hr on average). These roads are exposed to severe and frequent landslides and floods, caused both by extreme rain and earthquakes leading to frequent community isolation. The non-availability of a reliable and resilient road network is strongly implicated as a contributory cause of Bhutan’s low Human Development Index score. Therefore a small-scale scoping study was performed to describe the problems more specifically and to define candidate procedures capable of keeping roads open and achievable, to a basic performance level, by non-skilled local communities.

Summary:  The mixing performance of complex fluids are compared against those obtained with a standard impeller spindle, to establish which geometry allowed reaching the best level of homogenisation and the more realistic viscosity measurements. The HRI is calibrated and then used for testing several materials in the field of pavement engineering. The whole experimental programme is simulated by means of CFD analyses. At last a comparison between CFD particles volume fraction and experimental tests will be carried out to validate CFD simulations and to asses whether CFD modelling could represent a valid support to optimise design and manufacturing efforts of non-standard equipment for rheometry of complex fluids.

VEDAT (Value Enhancement for Data from Assets & Transactions)
  • Funder: Innovate UK
  • Total value: £359 000
  • Start to end date: Sep 2014 – Nov 2016

Summary: Transport Management Systems provider Microlise has partnered with the University of Nottingham to get a wider range of valuable information from data routinely collected by road vehicles. The objective of the “Value Enhancement for Data from Assets & Transactions” (VEDAT) project is to achieve customer and market value from the high volumes of complex data (Big Data) generated in real-time through telematics technology. Innovative tools and solutions that result in significant cost savings and create new value propositions within the transport and logistics sector have been created as a result of the project.

The backdrop to VEDAT is the millions of miles worth of event data generated through Microlise telematics solutions each day. This data is used at a local level by customers to understand driver behaviour, vehicle usage and customer service levels. However, taken as a whole, the data captured around driving style, risk areas and vehicle flow rates represents a whole additional dimension for Microlise to provide further innovative solutions.

The VEDAT project takes advantage of Microlise technology and market experience, as well as the expertise in hardware products of the company’s research & development team, and will utilise the OEM relationship between Microlise and a global vehicle manufacturer also involved in the project. The University of Nottingham provides the extensive skills available through its’ Automated Scheduling, Optimisation and Planning (ASAP), Advanced Data Analysis Centre (ADAC) and Nottingham Transportation Engineering Centre (NTEC) teams.

Whole-life Cost Assessment of Novel Material Railway Drainage Systems
  • Funder: EPSRC, Rail Standards & Strategy Board, UK Dept. for Transport
  • Total value: £591,597
  • Start to end date: 2015 - 2019

Summary:

Water plays a significant role in the degradation of railway infrastructure with high associated maintenance and repair costs. Climate change is predicted to result in more extreme weather and flash flood events. The railway drainage systems will therefore be put under severe strain. Much of the UK railway drainage infrastructure is old and in need of repair or replacement while traffic growth reduces the opportunities available to carry out maintenance. In light of these issues, this project focuses on providing novel and easily installed railway drainage solutions which make use of lightweight and cost-effective 'new materials'. Their use is investigated by full-scale, physical centrifuge and numerical modelling and some in-situ monitoring.
