The American Society of Civil Engineers (ASCE) is forming a standards committee to develop a national consensus standard guideline (non-mandatory standard) governing the design and installation of permeable interlocking concrete pavements (PICPs) for municipal street and parking lot traffic applications. The committee will be based within the Transportation and Development Institute.

Users of the standard guideline will be engineers, architects, landscape architects, agency engineering staff members at the municipal, state, and federal levels, material producers, and installation contractors all using pavers in sustainable and “green” street applications.

The scope of the standard guideline will address use of PICP in road applications with loading conditions not to exceed 80,000 pounds. The standard guideline will not specifically address design requirements for the subgrade support of PICP. Instead, the standard will specify the performance requirements for the subgrade to be addressed by a geotechnical engineer.
