Enhanced Binder for Longer Lasting Road
Crumb rubber doesn’t just help solve a waste problem — it upgrades the performance of bitumen binders.
When integrated into bitumen, crumb rubber particles swell and interact with the binder matrix, increasing its elastic recovery and flexibility. This improved elasticity allows the binder to absorb and dissipate stress more effectively, especially under heavy traffic loads and thermal cycling.
The result is a more resilient pavement that is:
-
Less prone to bottom-up cracking, one of the most common and costly failure modes in asphalt
-
Better able to resist reflective cracking in rehabilitated pavements
-
Suitable for high-stress areas, such as intersections, bus routes, and rural highways with wide temperature swings
OLEXOCRUMB Product Range
OLEXOCRUMB Sealing Grades
The Olexocrumb spray sealing range combines performance-proven binder technology with recycled crumb rubber from end-of-life tyres — supporting a more circular economy while delivering longer-lasting road surfaces.
All three products in the range are designed for spray sealing applications and provide varying levels of performance to suit different road stress environments and network needs:
🔹 S5R – Rubber-Modified Entry Binder
Based on conventional paving-grade bitumen, S5R introduces crumb rubber to enhance elasticity and flexibility over unmodified binders.
-
Ideal for low-stress environments and reseal programs as an C170 alternative
🔸 S9R – Crumb Rubber PMB
S9R strikes a balance between performance and ease of handling, offering enhanced resistance to thermal cracking and deformation.
-
Suitable for most local roads and moderate traffic loads
🔶 S15R – Performance Rubber Binder
S15R is a premium crumb rubber PMB tailored for moderate stress sites, including SAM treatments. It features a higher rubber content for improved elasticity and deformation resistance.
-
Suitable for local and regional roads with moderate traffic loads
-
Helps reduce reflective and fatigue cracking
