PAVE-FLEX 140
PAVE-FLEX 140 is a polymeric asphalt modifier used to modify 60/70 penetration-grade asphalt so that the resulting asphalt binder delivers higher-performance paving. The modifier is engineered to improve the asphalt-binder performance envelope supporting rutting resistance, cracking resistance, shoving resistance, stripping resistance, improved adhesion and improved load performance.

PMA Comparison Report (PaveFlex 140 versus SBS) — MSCR study
Laboratory comparison study: PAVE-FLEX 140 versus locally sourced SBS polymer, prepared by Sabr Engineering Consultancy for Delmon Group of Companies, testing PAVE-FLEX 140 at 7.5% and 8.0% against SBS at 4.0% and 4.5% using Ras Tanura and Riyadh refinery 60/70 penetration bitumen, reported against AASHTO T 350 (MSCR), AASHTO M 332, AASHTO T316 and AASHTO T315 criteria. An objective comparison study: it is not an approval, and the study's own summary reports lower Jnr for SBS under standard traffic conditions in some cases.

King Saud University research thesis — rheological properties of local polymers
Cited external research: a 2016 King Saud University thesis by Ali Babalghaith tested six locally used polymers including PAVE-FLEX 140 and reported higher penetration and softening points and a higher G-star over sin-delta versus SBS KTR 401, indicating higher rutting resistance. Cited from our own report; the original thesis is not held in our documentation set. This is external, cited research — it is not an approval of any Delmon product.
