The use of structural backfill and newly developed aesthetic facing systems can be used to create gravity wall structures. Installation details, the proper construction sequence, and specifications are also addressed.

This program will provide an overview of Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS), a bridge design concept being promoted by the Federal Highway Administration to accelerate construction time and offer significant cost savings for the construction of local, county and state bridges. Segmental Retaining Wall (SRW) facing elements, along with geosynthetic reinforcement material, is proving to be a viable solution for a majority of the bridges known to be structurally deficient and in need of replacement across our nation. The presentation addresses the design concept, key materials, specifications and important construction details. A case study example illustrating the construction sequence is also provided.

This presentation covers best practices for designing, specifying and building segmental retaining walls (SRWs) as developed by industry since its start. The purpose of this session is to promote a zero wall failure initiative by educating the designers and specifiers in best practices related to segmental retaining walls.

This program will provide an overview of how interlocking concrete pavement systems can be applied to commercial projects to enhance the value, performance and pavement life cycle costs. The presentation addresses how pavers can aid in defining themes, character and space through creative patterns, and explains how paver systems work. Site conditions that impact paver performance are highlighted, including issues related to access, safety, specifications, and construction details. Finally, the program concludes with a discussion on sustainability and attributes that pavers offer commercial installations.

This presentation provides an introduction to permeable interlocking concrete pavement (PICP) systems. An overview of the problem with impervious surfaces and the advantages of Low Impact Development, specifically stormwater infiltration practices through pavement surfaces. The presentation addresses designing for hydrological and structural requirements, and reviews required details. The design approach discussed is based on the Interlocking Concrete Pavement Institute’s PICP design manual. Specifications and maintenance requirements are reviewed along with information on winter performance. Several project case studies illustrate the construction process.

This program provides a brief overview of Permeable Interlocking Concrete Pavement (PICP) systems and then focuses on the long-term surface infiltration performance of these effective stormwater control measures. Mechanisms for sedimentation and clogging of PICP joints is discussed along with a review of ASTM C 1781 testing procedures. Total Suspended Solids (TSS) removal efficiencies and current research on variables that contribute to hydraulic performance of PICPs are discussed. The presentation concludes with information on surface infiltration maintenance and restoration methods including a review of available cleaning machines. PICP maintenance costs and inspection checklists are also reviewed.

One of the most exciting developments in outdoor living is the arrival of ¾” thick porcelain outdoor pavers. The concept began to spark interest in 2012 and is continuing to grow in popularity. Outdoor porcelain pavers have the same benefits as regular porcelain –being frost-resistant, skid-resistant, durable and easy to clean – combined with incredibly high breakage loads (up to 2,000 pounds) creates the perfect solution for gardens, terraces and high traffic outdoor areas. Outdoor porcelain pavers can be dry laid onto grass, gravel, dirt and sand – or onto terraces and roofs using raised supports – without grout, adhesives or specialized workers, making installation incredibly easy.

This presentation will describe how PICP systems are designed and constructed. Examples will illustrate the keys to properly constructing and maintaining these effective stormwater management systems. An update on the Southeast Atlanta Green Infrastructure Project will be provided highlighting how Atlanta converted six miles of impervious roadway to PICP to reduce flooding and combined sewer overflows. The presentation will conclude with lessons learned related to utilities, roadway slopes, and maintenance.

This program begins with a brief summary of the evolution of stormwater management beginning with conveyance and transitioning to water quantity management, and most recently stormwater treatment. Stormwater Control Measures using Low Impact Development and Green Infrastructure design that can accomplish all of these objectives are now desired in many municipalities that deal with flooding or have environmentally sensitive waterways. This presentation will compare surface-based BMPs to manufactured treatment system options, and highlight Permeable Interlocking Concrete Pavement (PICP) as a viable solution to address conveyance, water quantity and quality objectives. A summary of the academic and industry research to date on using PICP for water treatment will be presented, along with strategies for combining the benefits of PICP with manufactured treatment systems.

This presentation reviews public safety and accessibility design considerations when selecting unit concrete pavers for walkway surfaces. Current ADA criteria, slip resistance standards and test methods, and latest developments related to a new roughness index for wheelchair vibration will be addressed. Other paver safety topics covered include: chamfer widths and ease of transition, visibility and color contrast, truncated dome requirements, permeable pavement surface openings, snowplowing, use of deicing chemicals, and traffic calming benefits.

Roof top paver systems have become an integral part of commercial roofing that not only improves the energy efficiency but also increases the life expectancy of the overall roof system. Changes to codes and standards along with recent storm events have brought wind uplift to the forefront as a vital component to roof top paver systems. The industry has developed various methods for addressing wind uplift, many of which are covered in this course.

This presentation reviews ASCE 58-16 Structural Design of Interlocking Concrete Pavement for Municipal Streets and Roadways, which is the design standard published by the American Society of Civil Engineers updated in 2016. The topics covered include design parameters and limitations, structural design, construction details, and specifications of interlocking concrete paver systems.

Concrete grid pavement is widely used across North America for various applications including “green” pathways, parking lots, and basic erosion control. This presentation reviews  the various applications for concrete grid pavements and provides important design considerations, product specifications and construction recommendations. Environmental benefits such as reduced runoff and heat island mitigation are also highlighted. The program will conclude with several case studies.

Roof top paver systems have become an integral part of commercial roofing that not only improves the energy efficiency but also increases the life expectancy. Roof top pavers provide a durable surface protecting the roofing system from thermal shock, UV degradation and impact. In addition to these benefits, roof top pavers also add the ability to increase the useable square footage of a structure by providing a durable pedestrian surface on roof decks.

This presentation reviews ASCE 68-18 Permeable Interlocking Concrete Pavement, which is the design standard published by the American Society of Civil Engineers in late 2018.
