POLYCOM STABILISING AID
Build stronger road pavement by adding PolyCom to the existing materials.
PolyCom Stabilising Aid is a high-performing road stabilisation product with applications for sealed or unsealed road construction and maintenance, mining haul road maintenance, transport hardstands, embankment stabilisation and earthworks in general.
PolyCom has a pronounced effect on the behaviour of the pavement such that maintenance is dramatically reduced which of course reduces life cycle costs.
The use of polymeric-based additives for stabilising pavement materials has increased rapidly in recent years. Advantages typically include a reduction in permeability, an increase in durability, a non-time dependent mixing phase, and the provision of flexibility. PolyCom Stabilising Aid a Polyacrylamide (PAM) is one such additive that has demonstrated such advantages.
POLYCOM STABILISING AID IS USED TO CREATE EFFICIENT & SUSTAINABLE ROADS.
POLYCOM APPLICATION IS SIMPLE & COST EFFECTIVE
PolyCom Stabilising Aid is supplied in 2kg packs and is applied at 0.002% by mass ratio which treats 100 tonne or 50m3 solid of material.
PolyCom Stabilising Aid eliminates expensive intermediate bulk container transportation, handling and application costs.
HOW DOES IT WORK?
PAM stabiliser plays an important role by providing electrostatic attraction among soil particles rather than introducing a chemical reaction to stabilise soil. The effective interaction of soil particle takes place when polymers are adsorbed onto the soil particles, and the adsorption process is significantly affected by the type of polymer charge and polymer molecular configuration. Adsorption of anionic PAM onto the clay particles and interaction occur by cation bridging, through which the polyvalent cations bridge the negative charged groups of clay particles and polymers together.
HOW IS POLYCOM APPLIED?
Simply apply PolyCom Stabilising Aid with our custom made dry spreader and work the ground as you normally would during your road construction or maintenance works. PolyCom comes in granular form. It mixes easily with difficult to mix materials and you can get optimum results with Grader mixing.
POLYCOM STABILISING AID
The comparatively small amounts of PolyCom dramatically increase the strength and running surface of your road and there are huge water savings during the road construction or maintenance process. Your pavements will be stronger and longer lasting, more water resistant and less dusty than stabilising with the usual methods because you'll have a tighter and better bound running surface that lasts.
PolyCom has impeccable environmental and OHS credentials. Speak to your local distributor to learn more.
PolyCom Stabilising Aid introduces water resistance, improved workability and increased strength, delivering a stronger, more resilient and environmentally sustainable platform for your project. Strengthened sub-grades deliver huge cost advantages by allowing more economic pavement designs and drainage options. Sub-grade capping substantially reduces, and can even eliminate, re-work from weather or traffic damage in cut to fill operations, again reducing project costs.
Adopting a PolyCom Stabilisation treatment with subgrade formation will increase the pavement Subgrade CBR which can be adopted for a rationalised pavement design. The ARRB mechanistic pavement design table for standard pavements suggest with a subgrade CBR of 9 a pavement thickness of minimum 200mm is required. The blue line indicates the PolyCom treated subgrade with an adopted CBR of 30 can adopt a minimum 100mm pavement. A minimum 50% material saving.
Treating pavements with PolyCom Stabilising Aid delivers comparable results to traditional stabilising methods with regard to strength, but also imparts a high degree of water resistance and all important flexibility. It is significantly more cost effective, there are no cure-time constraints and the pavement is re-workable at anytime. All ground improvement work with PolyCom Stabilising Aid can be achieved using standard construction plant or stabilising machines
UNSEALED PAVEMENT STABILISATION
Applying PolyCom Stabilisation Aid to your unsealed road network will free up plant, resources and funds to better manage your asset. PolyCom will create a more efficient asset management practice by eliminating reactive work practices.
Stabilising with PolyCom will extend the maintenance period 4 to 6 times longer.
Stabilising shoulders with PolyCom Stabilisation Aid minimise risk due to reduced construction time and eliminating the unsafe excavation drop off associated with conventional construction process.
Further benefits of incorporating PolyCom for Shoulder Stabilisation is:
√ Improved road user safety
√ Effective pavement widening
√ Improves water resistance (water is shed further from the road pavement)
√ Reduces maintenance grading and the need to replace material
√ Stabilised shoulders provide much better lateral support for the road pavement
POLYCOM REQUIRES NO LARGE SPECIALISED EQUIPMENT
Simple, Easy & Cost Effective
PolyCom can either be spread dry with purpose-built spreading units or wet with an eductor and will not disrupt normal construction practices. Once spread, the standard road construction equipment are required, grader, rollers and a water truck.
The versatile PolyCom Dry Spreader allows for total control over spread rates in a wide variety of applications.
The Eductor is a simple device designed for the purpose of applying PolyCom
Stabilising Aid to any water cart. This device ensures thorough mixing of water & PolyCom preventing jellying.
