⚠️ Khanh Le Pass "Ripped Apart": Comprehensive Solution For The Bloodline Road From OKASAN LIVIC VIETNAM

The serious landslide and subsidence incident at Khanh Le Pass (National Highway 27C), the vital route connecting Nha Trang and Da Lat, once again confirms the urgent need to apply sustainable construction and repair solutions that can prevent natural disaster risks.

1. 🚨 Consequences of Weak Roadbed and Technical Challenges

The damage situation at Khanh Le Pass is very complex, including:

* Subsidence and Road Surface Fractures: More than 40 damaged points, with deep cracks and fractures, show that the weak soil underneath has lost its load-bearing capacity or has been structurally broken due to water seepage. This requires a drastic reduction of the load on the foundation.

* Landslides and Slope Erosion: Thousands of cubic meters of rock and soil have slid from the slope, and the erosion of the negative slope has caused the risk of losing the entire roadbed. This requires a permanent reinforcement and effective anti-erosion solution.

2. 🛠️ Applying Japanese Technology Solutions From OKASAN LIVIC VIETNAM

To simultaneously solve the above two core problems, Okasan Livic Vietnam introduces two advanced material solutions: EPS lightweight material and Takino Filter Vegetation Mat.

A. Roadbed Stabilization and Anti-Subsidence Solution: EPS (EDO-EPS)

This is a solution that focuses on solving the problem of weak ground causing subsidence:

* Product: EPS Lightweight Material (EDO-EPS) In Road and Bridge Construction

* Principle: EPS has a super light volumetric weight (only 1% ~ 2% compared to conventional fill).

* Effectiveness: When using EPS to replace the traditional roadbed at subsidence points, the load on the weak ground is significantly reduced (reduced by up to 98%). This eliminates the main cause of subsidence and helps stabilize the roadbed in a sustainable way.

B. Slope Reinforcement and Landslide Prevention Solution: Takino Filter Vegetation

Here is a bioengineering solution to protect vulnerable slope areas:

Product: Takino Filter Vegetation Mat
Principle: It is a highly porous non-woven filter mat that allows water to drain easily but prevents the loss of soil and seeds.
Effective:
- Anti-erosion: Effectively prevents surface erosion caused by rain and floods.
- Bio-reinforcement: The mat creates an ideal environment for rapid root growth, forming a strong root network through the soil layer. This vegetation cover forms a biological armor, helping to stabilize the slope in the long term, preventing landslides from recurring.

Okasan Livic Vietnam is committed to providing high-quality solutions and materials to build and maintain a solid, sustainable and safe Vietnamese transport infrastructure system against complex natural disasters.
