On Monday July 27, 2020, Enoch Group Data teamed with Pro Pavers Houston to evaluate the interlocking pavement driveway for Heritage Grand Community Center in Katy, Texas and provided a Pavement Condition Index (PCI).
Will Enoch, a 32 year veteran within the segmental pavements field, headed the project along with Pro Pavers Houston President, Travis Pavelka. A distress survey was performed which determined the interlocking PCI using an Interlocking Concrete Pavement Institute (ICPI) and Applied Research Associates’ (ARA) program.
The program is based upon ASTM 2840 and inputs pavement distress data including type of distress, severity level of distress and quantity of distress. These distresses include damaged pavers, depressions, edge restraints, excessive joint width, faulting, heaves, horizontal creep, sand joint loss/pumping, missing pavers, patching and rutting. One of the actual field survey sheets is shown below:
Each interlocking pavement section starts at a condition level of 100%, meaning excellent. The distresses along with their severity level and quantity receive a deduct value that reduces the entire pavement section’s value, rendering the entire interlocking pavement section a score from excellent to failed. Below is the ICPI PCI chart:
Enoch Group Data processed the interlocking pavement distress data from the field survey and produce interlocking pavement condition indices throughout the interlocking pavement sections. In the case of the Heritage Grand project, the four sections were averaged to provide a PCI for the entire branch on the property. In addition, there also were 900 square feet of discolored pavers that negatively affected the aesthetics of the pavement but not the structural integrity of the interlocking pavement system.
An evaluation report was produce for the client which contained the PCI, contributing factors leading to distress, recommendations to remedy the distresses and included an enhancement proposal, as well as future maintenance. An every three year evaluation was part of the recommendations.
This interlocking pavement evaluation is a benchmark for Heritage Grand. When layered over future evaluations, a deterioration rate may be established. This crucial data can be used to determine whether the interlocking pavement may be repaired or replaced.
Pro Pavers provided the rehabilitation service to correct the distressed areas we surveyed for Heritage Grand.
Enoch Group Data is currently networking with interlocking pavement contractors to provide evaluations and proposals to enhance the beauty and structural integrity of interlocking pavements.
