1 YHAUC RECYCLE GROUP UPDATE 22/02/2008

2 Advice Note No. 2007/01 – HAUC UK Recommendations:  Interim measure until new SROH.  Names approved Foamed Bitumen Mixes & properties.  Series 800 Hydraulic Mixtures (HBMs) approved without the need for a trial. No suppliers in Yorkshire at the moment.  Guidance on the testing regimes for ARM’s.

3 YHAUC RECYCLE GROUP UPDATE 22/02/2008 Advice Note No. 2007/01 - Moving Forward:  YJUG and YJAG reviewed this document.  YHAUC approval is now required to adopt the advice note for use across Yorkshire.  If agreement reached today, this procedure will be used as the model to enable material approval after successful appendix A9 trials in the Yorkshire area, without the need for additional trials. 2 sites have completed a two year trial & passed. 1. EDS in Sheffield. 2. CBEM3 in Leeds.

4 YHAUC RECYCLE GROUP UPDATE 22/02/2008 Group Discussion

5 YHAUC RECYCLE GROUP UPDATE 22/02/2008 EDS material approval update:  Frequency of testing agreed with S.Y. Lab.  Lab CBR tests satisfactory.  Water soluble sulphate content - Pass.  Oxidisable sulphides content - Pass.  Soundness – Pass.  Frost susceptibility – Pass.  LA Coefficient – Pass.

6 YHAUC RECYCLE GROUP UPDATE 22/02/2008 Inconclusive Results due to insufficient data: Insitu plate CBR testing, not enough sites. 90 day cube strengths insufficient results. Reasons Why: 1.Number of reinstatements available for testing. 2.Insufficient material demand. 3.Asbestos testing regime at S.Y. Lab. 4.Insufficient material demand to allow an acceptable testing frequency. Only National Grid (Gas) using plant so far.

7 YHAUC RECYCLE GROUP UPDATE 22/02/2008 S.Y. Lab advice to Recycle Group :  Cannot give full approval at present. i.e. Only narrow trenches & <2 sq m openings in type 3 & 4 roads & footways allowed for SMR machine mix material.  With a more proactive approach a full report in 3 months.

9 Buy Recycled Event at Leeds Yorkshire Playhouse. Event Overview: Eco Depot – Wood burning to fuel a ‘bio–mass boiler’ CBEM. Compost manufacture to BS 3882:2007 topsoil using green waste. Recycled Plastic kerbs and Bollards. Barnsley - Recycled type 1 sub-base & footway base. Highway Authorities should communicate the results of their recycled materials trials to other Highway Authorities & Utilities. Good ideas must be embraced.

10 YHAUC RECYCLE GROUP UPDATE 22/02/2008  YHAUC visit to EDS recycling plant at Sheffield.  2 visits proposed for late March, dates to be confirmed shortly.

11 YHAUC RECYCLE GROUP UPDATE 22/02/2008 The Future:  HA’s and Utilities must be aiming for the same environmental goals.  Organisations need a policy on environmental issues with an achievable implementation plan. A Suggested Way Forward: YHAUC members to adopt an Environmental Management System – N.G. Gas use ISO
