Design Professional turn to interlocking concrete pavements and permeable interlocking concrete pavements because they offer lower initial and life cycle costs and provide environmentally sustainable solutions. ICPI provides resources on ICP and PICP design, construction, and maintenance. These include technical bulletins, guide construction specifications, detail drawings, design manuals and software. Design professionals should specify contractors with ICPI certification in concrete paver installation.
INTERLOCKING CONCRETE PAVEMENT (ICP)
Concrete pavers are compacted into coarse bedding sand, the joints filled with sand and compacted again to interlock. The paving units and bedding sand are placed over an unbound or bound, compacted aggregate base. ICP can be designed to receive heavy traffic from major urban thoroughfares. Designers should follow the American Society of Civil Engineers national standard on ICP structural design (ASCE 58-10).
PERMEABLE INTERLOCKING CONCRETE PAVEMENT (PICP)
Intended for stormwater runoff reduction, solid concrete pavers are placed over a bedding course of highly permeable open-aggregate aggregate. The joints are filled with open-graded aggregate making
the surface 100% permeable. The pavers and bedding layer are placed over an open-graded base and subbase which create a reservoir for stormwater storage and infiltration. PICP’s ability to reduce or eliminate stormwater runoff, even in intense rain events, also reduces pollution. PICP is intended for parking lots and low volume streets.
Design Professionals choose concrete pavers for:
- Rapid construction using mechanical installation equipment
- Low maintenance costs
- Fast surface reinstatement after underground utility repairs
- Traffic calming and increased safety
- Upscale visual appeal
- Runoff and pollutant reduction with PICP
ICPI's technical and educational resources provide design professionals with the latest design insights and technical developments on interlocking concrete pavement and permeable interlocking concrete pavement.
