REQUIREMENTS Product to be manufactured only by the Certificate Owner or Certificate Owner s authorised manufacturer certificated to the current BS EN ISO 9001, following training and receiving a certificate of approval from the Certificate Owner Product to be manufactured using only the raw materials authorized by the Certificate Owner: Reclaimed Asphalt classified to BS EN Aggregate to BS EN Paving Pellets covered by BSI Certificate Number FM , comprising controlled bituminous binder addition Product to be installed only by the Certificate Owner or Certificate Owner s authorised installer meeting the requirements of NHSS16 or NHSS BS EN ISO 9001 PLANNING PROCESS The objective was to plan and develop a Factory Production Controlled (FPC) process for manufacturing BS EN compliant Stone Mastic Asphalt using planings that are crushed, screened, analysed and then blended with aggregate and Paving Pellets in strict adherence to the Quality Management System (QMS). Following successful Type Testing conforming to BS EN , numerous field trials and additional laboratory trials were carried out over a 3-year period. As investment in machinery and access to high PSV surface course planings was required to move to commercial scale production, as an interim step, the Company started out producing the materials in line with the same process however using virgin aggregate. This product was granted certification by the BSI on 05 November 2015 with Certificate Number 0086-CPR Certificate of Conformity of the Factory Production Control in respect of EN :2006 Stone Mastic Asphalt. Further funds were raised from the Kent Lane Rental Fund that enabled the Company to invest in multiple additional performance trials to further verify the performance. The Company also raised funds to invest in covered storage, crushing, screening, blending and bagging equipment required to manufacture the product. Page 5 of 11
