Efficient bridge abutment with a mechanically stabilized earth wall using MIRAFI
Overview
The NLEX-Ciudad de Victoria Interchange project aimed to improve mobility and accessibility in Bulacan, connecting Bocaue, Sta. Maria, Pandi, Norzagaray, Angat, and nearby towns. The bridge abutment construction had to be completed within a tight deadline of less than 10 months, and the challenge was that the abutment needed to be built on soft foundation soil.
Challenge
Design & Construction:
To meet these requirements, the chosen design for the project was a Mechanically Stabilized Earth Wall using MIRAFI® Polyfelt PEC Series composite geotextile. This system allowed the use of on-site soil backfill, as the composite geotextile had excellent drainage properties and could reinforce finer-grained soils. The installation process was straightforward, involving laying the geotextile horizontally on the prepared surface with slight tensioning, followed by placing and compacting the backfill soil.
Solution
The Mechanically Stabilized Earth Wall system proved to be the preferred choice for both designers and contractors. Its advantages included an easy and rapid construction technique, superior performance properties of the geocomposite, and cost-effectiveness.
Please note that imperial conversions for measurements were not provided in the original text, so no conversions are needed in this case.

Providing long term stabilization for drainage channel
PROPEX Armormax and PROPEX Pyramattress, an engineered mattress system that uses PROPEX Pyramat 75 HPTRM to construct a geosynthetic/soil/rock composite for protection of channels, slopes, and spillways.

Steep slope stabilization at SR-11 KYTC DISTRICT 10
The PROPEX Armormax system helped KYTC meet their goal of providing a safe, efficient, environmentally sound and fiscally responsible option to repair the slope while also ensuring access to the state park and economic growth in the surrounding area.

Providing levee resilience and durability
Full scale installation of the EEAS began in 2015 and has since been installed on over 100 miles of earthen levees in the New Orleans area. Since installation, multiple levees have experienced overtopping from major hurricanes, but have not breeched.
