Black Rock Bitumen supplies polymer modified bitumen — including PMB, plastomeric (Grade P), elastomeric (Grade E), and crumb rubber modified binders — enhanced with SBS, EVA, and recycled rubber for superior elasticity, rutting resistance, and fatigue life. Sourced from Dubai, UAE and shipped worldwide, our PMB grades are built to extend pavement service life on heavy-traffic roads and infrastructure projects across variable climates.
What Is Polymer Modified Bitumen?
Polymer modified bitumen (PMB) is conventional bitumen enhanced with polymers such as SBS or APP to improve its elastic and thermal properties. This modification upgrades the binder’s resistance to deformation, cracking, and temperature-related stress compared to standard grades.
The polymer network improves the bitumen’s elasticity, allowing it to stretch under load and recover its shape rather than crack or rut. This makes PMB especially effective for roads facing heavy traffic loads, temperature extremes, or repeated stress cycles.
PMB grades — such as PMB 40, PMB 70, and PMB 120 — are specified by softening point, elastic recovery, and penetration values for project needs. Governed by standards like IS 15462 and ASTM D6114, this classification helps engineers select the right binder for durable, high-performance pavements.
