Permeable Pavement Testing

Brick Paver Repair Houston, provides Permeable Interlocking Concrete Pavement (PICP) infiltration rate testing throughout the state of Texas. All field evaluations, data collection, calculations, and reporting are performed in-house to ensure accuracy and consistency. Testing is conducted in accordance with ASTM C1781 standards.

How We
Test

PICP Infiltration Rate Testing

We measure the rainfall rate (inches per hour) that a permeable interlocking concrete pavement system can absorb. This data helps determine whether the pavement is functioning as designed for stormwater management.

Field Data Collection

A weighed amount of water is poured through the test ring, and the time is recorded from the start of the pour until water is no longer visible on the pavement surface. This ensures consistent, repeatable testing methodology.

Multiple Test Locations

Depending on pavement section size, multiple tests are conducted within a given area. This approach ensures representative results across the full permeable pavement system.

ASTM C1781 Field Procedure

Testing is performed in accordance with ASTM C1781 using a specified diameter ring placed atop the permeable pavers. A measured volume of water is introduced while maintaining the required pour level.

Infiltration Rate Calculation

A standardized formula is applied to calculate the pavement’s infiltration rate in inches per hour. The resulting data provides a quantifiable measure of system performance.

Benchmarking & Long-Term Monitoring

We recommend establishing baseline infiltration rates immediately after installation. Future testing can then be compared against benchmark data to evaluate performance trends and determine when maintenance may be required.

Brick Paver Repair Houston’s testing of PICP stormwater runoff performance and interlocking pavement distress survey data were featured in the May 11, 2018 issue of Erosion Control / Stormwater Magazine (article by Carol Brzozowski). This publication highlights our ongoing work to help permeable pavement systems function as designed.
