POLYFLEX <strong>65</strong><br />
POLYMER MODIFIED BITUMEN<br />
The <strong>Polyflex</strong> binder range consists of high polymer content sBs modified bitumens.<br />
PRINcIPaL aPPLIcaTION<br />
<strong>Polyflex</strong> <strong>65</strong> is mainly used in thin layer surface courses (thin layer asphalt). It is also used in stone<br />
mastic asphalt (SMA). The binder is also recommended for asphalt concrete or macadam base/<br />
binder courses where increased flexibility of the pavement layer is required.<br />
aDvaNTagEs OF POLYFLEX IN HOT MIXEs<br />
• Improved durability.<br />
• Better aggregate coating.<br />
• Increased resistance to rutting.<br />
• Improved ageing properties.<br />
• Increased resistance to fatigue.<br />
• Improved performance at extreme road temperatures.<br />

BENEFITs OF UsINg sBs POLYMER<br />
Styrene-Butadiene-Styrene (SBS) gives bitumen the following properties:<br />
• Enhanced storage stability.<br />
• Increase in viscosity/stiffness.<br />
• Increase in softening point.<br />
• Decrease in brittle point.<br />
• Increase in tensile strength.<br />
• Increase in ductility.<br />
The <strong>Polyflex</strong> range also includes <strong>Polyflex</strong> 75 and <strong>Polyflex</strong> 90.<br />
<strong>Polyflex</strong> 75 is recommended for use in Porous Asphalt.<br />
<strong>Polyflex</strong> 90 is recommended for surface course mixes which require additional<br />
binder film thickness to improve durability and rut resistance.<br />
