NH-11 of Bharatpur Mahua section is subjected to heavy traffic & heavy monsoon rains. As a result, existing pavement was cracking.
Due to the heavy traffic load on NH 11, the existing pavement was frequently subjected to Fatigue and cracking. During monsoon season, water use to penetrate inside and deteriorate the pavement, which further propagated the cracks. The depth of the crack was around 5mm and was continuous, which lead to regular maintenance, incurring large amount of direct and indirect cost.
Considering the magnitude and frequent maintenance happening of this stretch of NH, decided to find a long term solution. The issue here is not only water infiltration, but it also needs stress absorption. Suggested product, Techglass AIC will provide dual functions, one is moisture barrier and another is SAMI (Stress Absorbing Membrane Interlayer). The solution suggested was laying of Techglass AIC, as the depth of crack, which were developed was around 5mm. This would work as a reinforcing effect of the low strain glass fiber strands to the asphalt system in combination with the moisture barrier. Basic care has been taken by providing crack sealant with leveling course wherever required, before placement of AIC. AIC was placed in taut condition with tack coat to bond with the overlay.
This stretch of NH-11 was subjected to heavy traffic loads and intense monsoon rains, leading to frequent pavement cracking. Water infiltration worsened the damage, causing fatigue cracks and requiring repeated maintenance, which increased costs.
Continuous fatigue cracking under heavy traffic.
Water penetration during monsoon deteriorating pavement layers.
Cracks of around 5 mm depth propagating across the surface.
High maintenance frequency and associated costs.
TechFab India proposed TechGlass AIC (Asphalt Interlayer Composite):
Acts as a moisture barrier to prevent water infiltration.
Functions as a Stress Absorbing Membrane Interlayer (SAMI) to absorb stresses and delay crack propagation.
Reinforces asphalt with low-strain glass fiber strands.
Installed with tack coat in taut condition, after sealing cracks and leveling where required.
Prevents reflective cracking by absorbing stresses.
Provides reinforcement to asphalt layers.
Enhances durability and service life of pavement.
Reduces maintenance frequency and costs.
Ensures smoother and safer driving conditions.
Successful installation of TechGlass AIC across the cracked pavement sections.
Improved long-term performance of the highway.
Reduced need for frequent maintenance.
Client satisfaction with durability, cost-effectiveness, and technical performance.
