High strength, high bearing capacity and high resistance to stress.
Grating structure with the good drainage function, do not accumulate rain, snow, dust and debris.
Ventilation, lighting and heat dissipation.
Explosion protection, also can add anti-skid serrations to improve anti-skid ability, especially in rain and snow weather to protect people's safety.
Anti-corrosion, anti-rust, durable.
Simple and beautiful appearance.
Light weight, easy to install and remove.
1. reinforces old asphalt concrete road surface and asphalt layer,and prevents damage.
2. rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction
3. road expansion and imnprovement project anby foud crack caused by old and new combination position and uneven
sedimentation.
4. soft soil base reinforcement treatment,which is favorable for soft soil water separation and concretion,restrains
sedimentation effectively,distributes stress uniformly an improve overall strength of road base.
5.preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack
caused by foundation crack reflection
