Interlocking Concrete Pavers on an Aggregate Base

Download DOC

This guide specification for concrete paver applications in the U.S. for concrete pavers and bedding sand over a compacted aggregate base for pedestrian and vehicular applications. The text must be edited to suit specific project requirements. This Section includes the term "Architect." Edit this term as necessary to identify the design professional in the General Conditions of the Contract.

Interlocking Concrete Pavement Overlay

Download DOC

This guide specification for the U.S. is for the construction of a new or rehabilitative overlay of concrete pavers and bedding sand over existing asphalt, concrete, or aggregate base. Applications include pedestrian and vehicular areas. The text must be edited to suit specific project requirements. This Section includes the term "Architect." Edit this term as necessary to identify the design professional in the General Conditions of the Contract.

Bitumen-set Concrete Pavers

Download DOC

This guide specification is for applications in the U.S. of concrete pavers adhered with a neoprene mastic to a bitumen-sand setting bed and tack coat over a concrete base. This construction assembly is for pedestrian and vehicular areas. The text must be edited to suit specific project requirements. This Section includes the term "Architect." Edit this term as necessary to identify the design professional in the General Conditions of the Contract. The terms concrete pavers, paving units, and units are used interchangeably. This specification does not apply to larger paving units that do not conform to the dimensional requirements of ASTM C936 such as precast concrete paving slabs.

Permeable Interlocking Concrete Pavement

Download DOC

This guide specification for U.S. applications describes construction of permeable interlocking concrete pavers on a permeable, open-graded crushed stone bedding layer (typically ASTM No. 8 stone). This 2 in. (50 mm) layer is placed over an open-graded base (typically No. 57 stone no greater than 4 in. or 100 mm thick) and a sub-base (typically No. 2 stone or similar sized material such as No. 3 or 4 stone). The pavers and bedding layer are placed over an open-graded crushed stone base with exfiltration to the soil subgrade. In low infiltration soils or installations with impermeable liners, some or all drainage is directed to an outlet via perforated drain pipes in the subbase. While this guide specification does not cover excavation, liners and drain pipes, notes are provided on these aspects.

Paving Slabs on an Aggregate Base

Download DOC

This guide specification for the U.S. is for paving slabs on a sand bed over a compacted aggregate base for residential pedestrian and driveway applications. Excavation and preparation of soil subgrade, subgrade drainage and the aggregate base are by others. Units no larger than 14 in. x 14 in. (350 mm x 350 mm) paving slabs are recommended for these applications. Slabs installed with these methods are not recommended for commercial or municipal applications, or areas subject to vehicular traffic. The text must be edited to suit specific project requirements for projects. This Section includes the term "Architect." Edit this term as necessary to identify the design professional in the General Conditions of the Contract.

Paving Slabs on Pedestals for Roof Plaza Decks

Download DOC

This guide specification for the U.S. is for paving slabs supported by pedestals for pedestrian roof plaza decks. Slabs installed with these methods are not recommended for areas subject to vehicular traffic. Paving slabs 12 in. x 12 in. (300 mm x 300 mm) in length and width or larger are typically pedestal set. The text must be edited to suit specific project requirements. This Section includes the term "Architect." Edit this term as necessary to identify the design professional in the General Conditions of the Contract.

Concrete Grid Pavements

Download DOC

This guide specification for U.S. applications is for concrete grid units placed on a sand bedding course over a compacted dense-graded aggregate base. The text allows an option of topsoil and grass in the grid openings over bedding sand or No. 8 open-graded aggregate in the grid openings and for the bedding course. This specification is for limited vehicular applications such as access roads and emergency fire lanes, as well as intermittently used overflow parking areas. This text must be edited to suit specific project requirements for projects. This Section includes the term “Architect.” Edit this term as necessary to identify the design professional in the General Conditions of the Contract.
