Sripath Participates in AfPA’s High-RAP Rejuvenator Trial

ReLIXER®, an Asphalt Recycling Agent or Rejuvenator, by Sripath Technologies®, was selected for a High-RAP Rejuvenation trial organized by AfPA & Fulton Hogan in City of Gold Coast, Queensland, Australia. In November 2021, the Australian Flexible Pavement Association (AfPA) organized a TechTalk Webinar on ‘High RAP Asphalt Mixes & the Role of Rejuvenators’, also sponsored by [...]

PGXpand Improves Highway Rutting in India

PGXpand®, a unique polymer specially engineered by Sripath Technologies, was successfully used by PATH India Ltd to improve rutting performance on a 4-lane km stretch of Agra-Gwalior Highway in India. PGXpand enhances the high temperature properties of bitumen without impacting low temperature properties. A mix based on PGXpand® Modified Bitumen delivers outstanding rutting resistance, fatigue properties, long-term durability, [...]

Creating a Stronger Base with Emulsion Stabilization

Base stabilization increases the bearing capacity and strength of the roadway. Cement Treated Base (CTB) or Cement Treated Sub-Base (CTSB) have been common and popular methods to stabilize the soil and aggregate layers in paving applications. However, another method is gaining wider use. An Emulsion Treated Base (ETB) is an aggregate stabilized with emulsion and cement. Adding an [...]

Why Specially Engineered Polymers Are the Right Choice

Polymer Modified Membranes have a long history in the roofing and building materials industries. In addition to improving high temperature properties, they provide superior crack resistance, particularly in cold conditions, where they have a high strain capability to cope with thermal shrinkage stresses. Additionally, they offer superior fatigue resistance and durability over standard bitumen. More recently, polymers have [...]
