Powderly Texas Road Rehabilitation
The Powderly, Texas road rehabilitation project uses Presto's GEOWEB® Geocell system to stabilize and protect against cracking and rutting as a durable, cost-effective solution for low-traffic rural roads
Project Overview
The roadway project in Powderly, Texas focused on rehabilitating a significantly distressed farm-to-market asphalt road. Due to the road’s visible cracking and rutting, a complete reconstruction was necessary. In addition, the road’s remote location and low traffic conditions encouraged the client to seek an economical solution to constructing a durable and long-lasting repair.
Challenge
The primary issue identified was the severe pavement distress, characterized by cracking and rutting. This distress indicated underlying problems with the subgrade stability. As a result, the compromised road surface could not be simply patched or overlaid. Furthermore, its remote location further complicated the situation, making material access and transportation challenging.
Several project constraints were identified during the planning phase.
- Due to budgetary constraints, a significantly cost-effective solution was required.
- Improving subgrade stability was vital in order to prevent future cracking and rutting.
- As a result of the logistical challenges posed by the remote location, traditional cement treatment methods were deemed unsuitable.
How did Ferguson Waterworks improve the subgrade stability and navigate the project's constraints?
To address these challenges TxDOT, in collaboration with UTEP, Presto Geosystems, and Ferguson Waterworks, opted for an innovative geosynthetic solution using Presto’s GEOWEB Geocell technology. The final design featured a 4” depth GEOWEB system filled with an aggregate base material over a prepared and compacted subgrade. The aggregate base course was 6 inches thick, with 2 inches left unbound, providing a strong sublayer before applying the asphalt wear course.
Road Rehabilitation Optimization Highlights
The project’s highlights include the successful application of GEOWEB technology, which provided an economical and efficient solution to the subgrade stability issue. The construction process was completed on time and within budget, demonstrating the effectiveness of the chosen method. The use of ATRA® keys for securing the GEOWEB panels and temporary stakes to maintain material position during infill were notable techniques that ensured the integrity of the installation. Overall, the project resulted in a durable and resilient roadway capable of handling future traffic demands.
