The Interlock Concrete Pavement Institute (ICPI) released two new Tech Specs this month. The additions increase the series to 21 technical bulletins on design, construction and maintenance of interlocking concrete pavement systems and specialty applications.

All 21 Tech Specs are available for free on the ICPI Website (http://www.icpi.org). Printed versions can be purchased in sets of 10 through the online store (http://www.icpi.org/shop).

Tech Spec 20: Construction of Bituminous-Sand Set Interlocking Concrete Pavement
This bulletin provides information on the materials and methods used to construct a bituminous-sand set interlocking concrete pavement system. Details of the construction process starts with a rigid concrete base followed by an emulsified asphalt tack coat, the layer of bituminous sand, neoprene modified asphalt adhesive and interlocking concrete pavers on the surface. Guidance on materials selection and required tools is also included.

Tech Spec 21: Capping and Compression Strength Testing Procedures for Concrete Pavers
This bulletin provides guidance for concrete paver manufacturers, testing labs and specifiers on ASTM compressive strength test methods. Recent changes to these methods now adjust for different compressive strengths due to various paver thicknesses. The publication explains how to cut test specimen coupons from paving units, cap them, and test them for strength with detailed instructions and flow charts. Testing labs following this guidance should see more consistent test results.

In addition, ICPI has launched a complete new version of Tech Spec 16: Achieving LEED Credits with Segmental Concrete Pavements to be compliant with LEED version 4. Since its release late last year, LEED version 4 introduces new credit and existing ones that can be supported by segmental concrete paving products and systems. This 20-page publication explains changes to the from the previous LEED versions and how the updated LEED Sustainable Sites, Water Efficiency, and Materials & Resources credit categories can take advantage of features of interlocking and permeable interlocking pavements, concrete grid pavements and paving slab systems. Special attention is given to credits on rainwater management, urban heat island reduction and to environmental product declarations.

About ICPI
The Interlocking Concrete Pavement Institute (ICPI) represents producers, suppliers, contractors, design professionals and consultants and supports its members in assuring segmental concrete pavement systems are the preferred choice for sustainable and environmentally friendly pavements in North America. ICPI aims to increase awareness, use and acceptance of segmental concrete pavement systems in North America through the development of marketing and technical resources for design professionals, contractors and homeowners.
