An independent study was conducted to determine how the physical and chemical properties of Gilsonite® uintaite performed compared to Trinidad Lake Asphalt (TLA). The study compared a typical mastic asphalt bitumen modified with 24.4% TLA and formulations of bitumen modified with Gilsonite® at significantly lower concentrations of 5%.
Gilsonite provides clear performance advantages over TLA
Compared to the TLA mixture, the samples modified with Gilsonite® uintaite provided greater resistance to rutting, cracking and deformation while also providing the ability to withstand colder temperatures without breaking.

Improved Fatigue Resistance
Gilsonitc® enhances viscosity and reduces fatigue and cracking
Improved Rutting Resistance
Gilsonite® increases softening point to resist rutting and moisture
Less material = less energy required and significantly lower costs
A formulation with 24.4% TLA uses five times the additive as a mixture using 5% Gilsonite®. This reduction in additives can result in a 13% or more decrease in materials costs. When combined with lower energy costs required for blending, Gilsonite® provides significant savings.
The findings clearly demonstrate that Gilsonite®-modified binders make stronger, longer lasting roads, and that Gilsonite® uintaite is a superior alternative to the industry’s current mastic asphalt standard.
