What is RoadPacker Plus ?

RoadPacker Plus requires only standard design, drainage features and construction methods.

Benefits of RoadPacker Plus:

RoadPacker Plus Saves Money

RoadPacker Plus by increasing densities, strength and C.B.R. values, significantly gives the user the ability to reduce base depths by more than 50%, saving on quantity of gravel, handling and other associated costs.

RoadPacker Plus can increase strengths in local or insitu materials usually considered unsuitable for road construction. Laboratory testing is recommended to confirm suitability.

RoadPacker Plus when used in unpaved roads greatly reduces maintenance by minimizing the damaging effects of water and traffic.

AIM:

To blend the required amount of RoadPacker Plus with water through the top 150mm of soil then evenly mix and physically compact into place.

Desirable Construction Equipment:

A Road Grader equipped with scarifiers.
Water Bowser - with known volume.
Rotovator/Disc Harrow/Pulvey Mixer - desirable but not essential if a road
grader is available.
Vibratory Compactor/Sheeps Foot/ Steel Drum (12-15 tonne )
Wobbly Wheel/Pneumatic Rollers - for thorough compaction..

Required Equipment:

Drum pump, Measured bucket, Safety Glasses and Gloves.

To calculate the amount of RoadPacker Plus required,

( Length x Width x 0.03 Litres )

Water: The amount of water required varies depending on the moisture content of the soil at the time of application. Enough water is to be added to bring the moisture content to 1 - 2% above the optimum

N.B. It may be desirable, from a construction point of view, to dry the insitu material prior to calculating the amount of water required, i.e. it is more accurate to apply 2ltrs. per/sq.m than 0.5ltrs per/sq.m.

Important: Once the quantity of RoadPacker Plus required has been calculated, judge approximately how many water trucks will be required to bring the moisture content up to the recommended level. For example: If four water trucks and 80 Litres of RoadPacker Plus are required to treat the road, then add 20 Litres of RoadPacker Plus to each load of water. If after two loads of treated water you only require one additional load, then add the remaining 40 Litres of RoadPacker Plus to the final load of water, this method will ensure the diluted RoadPacker Plus is spread evenly over the area treated and the water content is correct.

Standard Method of Construction

1. Grade and contour road to finished levels and cross fall. Use the grader blade to cut and form drainage channels on both sides of the road to ensure good drainage. Standard road building methods apply.
   
2. Rip the road with grader's rippers to a depth of 150 mm. Accurate depth is important for calculating product concentrate required. Break up lumps with roller and windrow.
   
3. Apply diluted RoadPacker Plus with water truck and windrow while applying to ensure product is mixed evenly. Bring moisture content to 1 - 2% above optimum using more water if necessary. Note: All concentrate must be applied at this time.
   
4. Re-grade and contour road.
   
5. Compact road using a 15 ton Pads Foot vibrating compactor , followed by the same sized steel drum vibratory compactor. If a rubber wheeled roller is available use it to obtain a final finish.

NB: A fine layer of crusher dust or gravel may be applied to the finished surface of a completed road showing slippery characteristics.

To cure road, apply RoadPacker Plus at a rate of 1:1000 for 2 - 3 days.

Manufacturers Recommendations For Use Of RoadPacker Plus

Suitability Criteria:

RoadPacker Plus Dosage:

The dosage of undiluted RoadPacker Plus is a constant for all materials recommended for use, i.e. 200 millilitres per cubic metre of RoadPacker Plus material which, at a base depth of 150 mm, equates to 30 millilitres per square metre of surface area to be treated. One litre of RoadPacker Plus is sufficient to treat 33.3 square metres (150mm base depth).

DOSAGE IS CONSTANT
