Permeability and capillary rise assessment:
Testing found that the combination of 3% GP cement and 5% Polyave C produced the lowest permeability, capillary rise and water absorption of the three pavement conditions tested. NTRO concluded that he addition of Polypave C and cement significantly increased resistance to water absorption
Stellenbosch University Research - South Africa, 2025
A 2025 Stellenbosch University study by the Department of Civil Engineering - Study Lead Prof. Kim Jenkins. The study investigated G5 natural gravel stabilised using several treatments, including untreated, flyash, slag, cement and cement with Polypave C.
The cement + Polypave C combination achieved the highest dry indirect tensile strength, unconfined compressive strength and monotonic triaxial results of the stabilised materials tested. The study found that adding Polypave C to cement enhanced the mechanical properties of the G5 pavement material.
Polypave pavement performance review 2005 - 2025 Pacific Highway, NSW Australia
Pavement sections originally constructed between approximately 2003 and 2007 were progressively reviewed, with 12 accessible sections reinspected by Polypave International in November 2025.
The assessment considered visible pavement condition, cracking and deformation, maintenance history and performance following many years of traffic and major weather and flood events
This is a long-term field assessment undertaken by Polypave International and is presented as observational evidence, seperate from the independent laboratory and university research.
Shark Creek - delivered approx. 2006 - withstood repeated flooding and heavy traffic with no structural failure
Uganda Ministry of Works & Transport
The Uganda Ministry of of Works & Transport, through Central Materials Laboratory, evaluated locally sourced gravel materials stabilised with different cement contents and varying concentrations of Polypave C.
The laboratory testing found that UCS strength increased as Polypave concentration increased, with the greatest proportional benefits occurring at lower cement contents.
