Polymer Modified Asphalt

Busphalt

Asphalt pavement for Bus lanes and bus stops

Contact

Overview

Fiber-reinforced asphalt pavement with improved rutting resistance, tensile strength, and shear strength using a hybrid fiber-reinforced pelletized high viscosity modifier with a special polymer blend technology.

Properties

01In the case of bus lanes and bus stops, plastic deformation and portholes occur a lot due to the stopping and acceleration/deceleration of buses.
02Asphalt pavement method exclusively for bus lanes that improves pavement performance by resisting high shear forces of bus lanes and bus stops
03Remarkably improved resistance to plastic deformation and cracking by applying high-strength epoxy resin and thermoplastic elastomer modifiers

Uses

01Bus lane olny
02Bus stop / BRT lane
