PGXpand Archives

PMB mixes have been popular for decades and are designed to maintain the integrity of the roadway while enhancing functional performance characteristics. Most virgin bitumen lacks the complete properties needed in quality to build high-performing roadways. Adding polymers to create a PMB can help strengthen and toughen the roadway surface. PGXpand®, a bitumen-friendly polymer additive, is uniquely designed to allow polymer modified bitumen (PMB) producers to boost the high temperature performance of the binder while maintaining low temperature properties. It minimizes SBS content, improves viscosity, supports higher filler loading, and provides better stability.

Video: 6 Ways to Cut Carbon Emissions in Asphalt Paving

TRANSCRIPT: Reducing carbon emissions in asphalt paving is an essential component of roadway infrastructure development and planning. Government agencies and municipalities, contractors, and producers are all exploring measurable ways to shrink the carbon footprint of roadway projects. Here are six of current trends in asphalt paving technology that aid sustainability goals. Lower Mix and Production Temperatures Using [...]

What is Polymer Modified Bitumen (PMB)?

Bitumen is relied on as the primary binder in asphalt mixes developed for roadway paving, with nearly 90% of the world’s road paved using the material. Despite its widespread use, bitumen as a sole source of binder in a mix has inherent shortcomings. On its own, bitumen can be susceptible to deformations as temperatures change including cracking in extreme [...]

Achieving More Durable Roadway Surfaces with Asphalt Paving Solutions

Roadway durability has always been a key consideration for departments of transportation and municipalities initiating development or revitalization projects. However, existing road conditions continue to miss the mark as surfaces deteriorate over time. In the United States, 39% of major roads are considered to be in poor to mediocre condition, leading to costs for both DOTs and consumers [...]

Overcoming Bitumen Quality Issues for Roadway Paving

Increasing demand for roadway construction and repair to support infrastructure in a more connected global economy is directly impacting the bitumen industry. The market is projected to grow at 4% CAGR by 2031, a rate tied to urbanization and increased availability of more sustainable practices for producing roadways that use the binder. However, those tasked with working with the [...]
