<h1 align="center"><b><span style="text-decoration: underline;">RENOLITH USE BY THE RTA AUSTRALIA</span></b></h1>
<h2 align="center">Summary of use of Renolith in NSW by:
The Roads &amp; Traffic Authority</h2>
<h1></h1>
<h1><b>                </b></h1>
<h1>In 2003 a3.5 km widening &amp; rehabilitation of the Pacific Highway was proposed under traffic:</h1>
<ul>
	<li>Initial scope was flexible pavement design using crushed low plasticity sandstone gravel with history of poor performance under traffic</li>
	<li>Traffic volumes very high with 30-40% heavy transport</li>
</ul>
Weather conditions wet at this time of year
<ul>
	<li>Trial Design involved the changing of the project scope from flexible to rigid build method - this resulted in reduction of overall project price based on unit rates by &gt;10% however substantial saving on the delivery of the works 8 weeks early due to higher production potential.</li>
	<li>Design was 300mm deep stabilization of 16kg/m2 of general purpose of cement, 1.6 L/m2 of Renolith</li>
	<li>General purpose cement plus Renolith gave early hydration benefits of assisting to hold unsealed pavement</li>
</ul>
Design still based on flexible performance due to the polymer therefore no AC surface treatment.

<h3 align="center"><b>Renolith build methodology adopted</b></h3>
&nbsp;

&nbsp;
<ul>
	<li><b>The process involves</b>:</li>
	<li>1 - preparation of pavement to -10+00mm design level</li>
	<li>2 - Spreading of GP cement by 28 ton spreader at 16kg/m2 (note generally dropped between 50 to 75 ton cement per day)</li>
	<li>3 - dosing of water tankers at approx. 1500 liters of Renolith solution to 14000 liters of water (product received in 1000 liter placons)</li>
	<li>4 - Connection of calibrated Wirtgen to dosed water tankers - it is noted that between 370 - 390 liters per 10 meters generally provides 1.54 - 1.68 L/m2 of Renolith application in ‘Base quality materials’ at 300mm depth.</li>
</ul>
&nbsp;
<h4><b>Renolith build methodology adopted</b></h4>
<ul>
	<li><b>The process involves:</b></li>
	<li>5 - the second stabilizer follows the principle machine to ensure mix quality and to maximize the time available at the end of the process for trimming for high standard ride.</li>
	<li>6 - the 2 pad foot rollers follow the second mixer to maximize rolling time - rollers walk out, grader reinstates surface, steel &amp; rubber rollers commence.</li>
	<li>7 - At completion of incorporation of product grader and finishing rolling continue until the end of the day</li>
</ul>
&nbsp;

&nbsp;

Renolith Production Potential

&nbsp;
<ul>
	<li>The process can produce 4000m2 a day and still meet the requirements as detailed in the Contract specifications such as R75 which relates to new works</li>
	<li>It is an advantage to place the cold joint of the day within a median or on a lane line.</li>
	<li>RTA has now successfully completed approx. 24 kms of such works and are currently delivering another 8 kms this financial year</li>
	<li>Production can be increase by additional establishments of stabilization teams</li>
</ul>
&nbsp;

Renolith Performance 2003 to 2006

&nbsp;
<ul>
	<li>The performance of works completed today has been very good with few problems noted.</li>
	<li>The traditional transverse cracking related to stabilization at 8 - 12 meters has been generally eliminated or reduced to minor standard reducing need for AC surface treatments</li>
	<li>Product is been successful with manufactured product; natural gravels need to be assessed on an individual basis</li>
	<li>Ride quality has been very good in accordance with specification</li>
</ul>

Renolith Potential Use

&nbsp;

&nbsp;
<ul>
	<li>The advantages of Renolith as a polymer include to OHS aspects such as using a solution rather than powder products that become airborne and create a OHS &amp; Environmental problem</li>
	<li>The proven performance of Renolith lends itself to be considered for additional usage including.</li>
	<li>* Incorporation into heavily bound select and sub base pavement layers on motorways to reduce the potential of reflective cracking</li>
	<li>* Cost effective reconstruction of major and secondary road networks</li>
	<li>* Incorporation with other produces where improve durability is required - with reduced risked of cracking such as capping or concrete</li>
</ul>
