PMB PG 76-10

POLYMER MODIFIED BITUMEN BINDER: PMB PG 76-10 (Elastomeric)

AASHTO M320 Compliant Performance Graded Polymer Modified Bitumen binder

DESCRIPTION

Petro Coast Polymer Modified Bitumen (PMB) Grade 76-10 (Elastomeric) is a performance grade bituminous binder used in pavement construction in order to meet the requirements of hot temperature climate and the heavy traffic loads.

SPECIFICATION COMPLIANCE

Petro Coast PMB PG 76.10 (Elastomeric) Grade binder fully meets the requirements of AASHTO M 320 Standard specification for performance Graded Bitumen Binder for use in pavement construction.

PRODUCT CHARACTERISTICS

The modification process of base bitumen is conducted using specialty Styrene Butadiene Styrene co-polymer, an Elastomer, in a purpose designed manufacturing plant using high shear rotor stator mill and is quality controlled to the target specifications. It exhibits exceptional storage stability under the standard conditions of hot storage as demonstrated by ASTM and NCHRP 459 protocols.

Petro coast PMB PG 76-10 grade binder is homogenous, free from water and does not foam when heated to 175®C.It meets following specification requirements:
