Council budgets are being blown away on unsealed roads*
PolyCom Case Study:
The following data has been compiled from field reports during 2017 in Victoria and New South Wales.
Ravel test results show material loss comparisons from 14 different unsealed roads of different material types and locations including sandy clays, pit gravel to manufactured crushed rock.
All data was verified to ensure accuracy.
Due to location variables such as weather, material and traffic loading this study represents strong proof of PolyCom product efficacy.
What is a ravel test?
A ravel test consists of placing a one square metre frame on the road, within the wheel path section and sweeping up all the loose fines available within the one square metre. These fines are then bagged, weighed and recorded. This process is repeated for treated and untreated sections of road up to four times per kilometre to aid in accuracy.
Results of PolyCom Treated vs Un-treated:
Sandy clay – treated = 93.7% less material loss
Pit gravel or ridge gravel non crushed – treated = 74.7% less material loss
Clay with some gravel (ready for re-sheet) – treated = 94.2% less material loss
a) PolyCom Treated roads yielded on average 329 grams per sq m
b) Untreated roads yielded on average 1,695 grams per sq m
Data averages show PolyCom treated roads lost 84% less road material than untreated roads.
The results confirm that PolyCom is very effective in lowering maintenance costs and making for a safer more sustainable unsealed road network that requires four to six times less maintenance grading.
Benefits of PolyCom:
- financially sustainable
- environmentally compliant
- reduced purchase of re sheet materials
- less trucking by using in-situ material
- considerable reduction in fuel use
- occupational health and safety compliant
- less repeat work
- reduced sediment run off from roads
- reduced mud and dust
- use existing crew and machinery and
- treated roads are less slippery when wet.
