DURAMENT can be applied with traditional road building equipment.

Stage 1: Mixing of DURAMENT with water in a tanker.

Stage 2: Site Preparation

Stage 3: GP Cement layering

Stage 4: Thoroughly mix the DURAMENT water mixture with GP cement and soil

Stage 5: Compacting and watering

Stage 6: Final roll and ready to introduce traffic immediately

Installation Process...

Cement spreading equipment spreads general purpose Portland cement at a rate calibrated to allow the correct volume per metre of cement to be spread evenly on the road area to be stabilized.


The cement spreader ensures that the cement is spread evenly over the area across the full width of the pavement to be stabilized. Cement is applied directly to the ground comprising the proposed road or road to be rehabilitated.


A water-cart containing a proportioned mixture of DURAMENT and water are then engaged in-train to a rotary hoe to mix the laid Portland cement into the existing ground having just been sprayed with the DURAMENTt and water mixture. Mixing depth is according to the design specifications in each case.


Portland GP cement, DURAMENT and water in the proportions required as specified by the manufacturer are mixed on site. When mixing, the concentrated Durament liquid into the water-cart no special mixing site need be provided. 
 This procedure can be done at any convenient place on or adjacent to the project area where the tanker truck/water cart can be positioned conveniently beside the bulk DURAMENT supply. The tanker truck should be filled with water, leaving sufficient capacity for the DURAMENT to be added.


When DURAMENT is mixed with the in-situ material and Portland cement, an exothermic reaction occurs between the cement and DURAMENT which changes certain characteristics of the cement to create a high tensile strength mixture which binds the aggregates and fines in situ, eliminating voids between the aggregate components and fines.


In order to continue forward progress, it is recommended that a second rotary hoe be used to make a second mixing pass to ensure a complete mixing of the pavement material.


Initial compaction should immediately follow completion of the mixing process and is undertaken by not less than two passes of a 10 tonne pad foot roller.
Initial compaction and grading is followed by trimming to finish level and fall by grader. The grader completes the initial grade to bring the road back to the design levels and designed road shape as the polymer increases the volume of the mix. Any excess material may need to loaded out for use in other areas.


If a gravel wearing course is required by the specifications, a tipping dump truck with a tail gate can be used to add a top course of neutral 10mm gravel prior to final compaction. This top course will provide a wearing surface to the stabilized pavement.


Secondary compaction is then undertaken by non-vibrating flat drum roller – minimum of two passes by a ten tonne roller or equivalent. Final compaction is then performed by multi pneumatic tyre roller in a minimum of two passes.


The finally rolled, smooth finished pavement will have cured sufficiently after two hours, to allow monitored, slow traffic to access the pavement.
