Setting Industry Standards through Research and Development Standards Development ICPI staff participates on ASTM and CSA committees governing paving product standards and liaisons with the American Society of Civil Engineers (ASCE), U.S. and Canadian Green Building Councils, Transportation Asso- ciation of Canada (TAC) and the Canadian Society of Civil Engineers (CSCE) to represent industry best interests. ICPI’s participation on ASTM and CSA committees has led to improvements in existing paver standards and test methods. ICPI Technical Bulletin Revisions In 2011, ICPI updated several of its key Tech Specs. Updated design procedures and referenced stan- dards have been included in each of these Tech Specs: Tech Spec 2—Construction of Inter- locking Concrete Pavements Tech Spec 3—Edge Restraints for Interlocking Concrete Pavements Tech Spec 4—Structural Design of Interlocking Concrete Pavement for Roads and Parking Lots Tech Spec 6—Reinstatement of Interlocking Concrete Pavements Tech Spec 16—Achieving LEED ® Credits with Segmental Concrete Pavement ASTM E2840 Practice for Surveying the Condition of Interlocking Concrete Roads and Parking Lots In December 2011, the American Society for Testing and Materials (ASTM) International approved a new standard practice for rating the condition of interlocking concrete pavements. ASTM E2840-11 Standard Practice for Pave- ment Condition Index Surveys for Interlocking Concrete Roads and Parking Lots provides guidance on conducting 8 visual surveys to assess roads and parking lots surfaced with interlocking concrete pavers. ASTM E2840 provides municipalities and private project owners substantial guidance on when maintenance is required by surveying interlocking concrete pavement for a range of conditions or surface distresses. The condition index also enables users to compare results to that from conventional asphalt and concrete. ASTM E2840 provides a familiar structure for inventorying and assessing the condition of interlocking concrete pavements for the purposes of asset management. The standard includes a list of interlocking concrete pavement distress types divided into three levels of severity: high, medium and low. This methodology considers the interactive effect of several distresses on the PCI value and can be used to compare performance of conventional asphalt and concrete pave- ments. ICPI Life Cycle Assessment Scoping Workshop Life Cycle Assessment (LCA) is a decades-old process for evaluating the environmental impacts of manufactur- ing and building. LCA is rapidly emerging in LEED and other evaluation methods as a means to assess lifetime sustainability of construction materials, assemblies and systems. The timing was right for the concrete paver industry to develop an LCA for ICP and PICP as a com- petitive tool against conventional pavement systems and to impact LCA in LEED. Towards this end, The ICPI Technical Committee hosted an LCA scoping workshop in August 2011. The one-day workshop was conducted by PE International and aimed to establish parameters for a full LCA study. Caltrans Institutionalization of segmental concrete pavement via adoption of specifications by state transportation agencies represents a key strategy for the industry. With financial support from California paver producer mem- bers, ICPI staff participated on a Caltrans Pervious Pave- ments Committee to produce a draft specification on permeable interlocking concrete pavements (PICP). This committee also consisted of Caltrans staff and represen- tatives from the California cement industry and pervious concrete contractors who provided input on a pervious ICPI Annual Report 2011
