Heavily used Haul Road Dust Suppression over the summer season.
The customer’s requirements was to minimise the use of water carts on this very large, 28km, site. The haul road was preloaded with sand 3-20m deep and due to the difficult material needing to be treated (fine sands), the Gravel Lock program included more frequent applications using less product.
Tara Iti Golf Course is an exclusive privately owned golf course in Mangawhai, New Zealand. The brief was to instantly reduce/eliminate dust for clients and staff driving around the cart roads and internal roads.
The pavement conditions prior to treatment was very dusty, the aggregate was in a fair condition with an existing depth of around 50mm. The mine has two types of material, a fine clay material on the Haul Road and gravel on the Service Road.
Spains Road in Kaitaia, Northland is built over a peat subgrade. Peat is characterized by large porosity and low density with a large water and organic matter content causing issues such as dust, potholes, corrugations, heaving and gravel loss.
This extremely busy carpark was very dusty and the aggregate had worn out.
The scope of works was to initially stabilize the insitu aggregate and leave it unpaved. However, after 2 years the contractor chip sealed the pavement without any further maintenance works and which is still in excellent condition to date.
To build a road using Gravel Lock’s HSC to equal the budget of existing construction method. This forest road had a very weak subgrade – brown rock over burden quarry run – which was failing under the logging traffic. Per kilometre the standard construction on this road was using 1200 cubic metres of 100-150 aggregate in the sub-base and was overlaid with 900 cubic metres of gap 65.

Improve the performance of the Failing Flexing Peat Subgrade.
Purpose: Stabilization/Dust Suppressant.
Prior to treatment aggregate consumption on this haul road was very heavy. Using the insitu material on site for this installation, imported aggregates were reduced to nil.

Marsden Point is not only the main port for Northland but it houses New Zealand’s only Oil Refinery. The Marsden Point Highway is the main arterial route for trucks to and from the hub. The pavement had begun to unravel and large potholes had formed.
REMEDIATION OF A FAILING PAVEMENT
The client needed to stabilize a very difficult access road to the main port through the town. A high organic black cotton soil was causing issues such as potholes, corrugations, heaving etc. The black soil was removed from the site and backfill was imported so construction of the site could begin.
The GCC countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates) depend heavily on the outside world for the supply of most of their aggregates due to lack of resources. Being able to stabilize insitu granular sand is a major breakthrough for these countries. Flexi-C-Ment was used in Dubai to stabilize a pull off lane (shoulder) in an industrial roadway and also a loading construction bay used for the sale of aggregate.
New Zealand's first-ever American-style private golf club with members handpicked to ensure the club maintained a laid-back, intimate vibe. Located on the Te Arai coast on an enormous sand dune, the developers brief was to build roads that looked like sand.
PROJECT – November 2015
Gravel Lock was approached to stabilize a newly formed road in Dharampur, Gujarat, one of the most sacred states in India. The college/temple had been constructed over a failing undeveloped clay haul road that constantly required expensive maintenance works. A 200mm gap 40/60 was laid down over the top of the existing roadway and the grader methodology was applied to this installation.

This public use runway is on Jaluit Atoll, a coral formation in the Ralik (western) chain of the Republic of the Marshall Islands, situated in the west-central Pacific Ocean. The Runway consists of crushed coral which had deteriorated over time resulting in loss of fines which in turn caused the pavement to deform and create potholes from poor drainage.
Urban Surf Wave Park is a project designed to be a world-class tourism destination. It’s Australia’s first facility to offer a wave park for recreation, sports, emergency services training, school programs and youth development. Gravel Lock is proud to provide the solution to this Company using recycled concrete over expansive silty clays with CBR’s of less than 1.5.
This 28km long 4 lane wide highway was one of the largest projects being constructed in New Zealand at the time. The highway was constructed over weak subgrades so it needed to be preloaded with millions of tons of sand and soil requiring strict environmental controls. Gravel Lock was proud to be a key supplier of CSC dust capping and erosion control in the Tauranga Eastern Link project.
This rest area is situated just off a very busy highway and experiences extreme amounts of through traffic on a daily basis. The Give Way area is prone to unravelling and potholing which causes road users to experience a negative experience when leaving this complex. Gravel Lock put down a trial of PHF Coldmix Pothole Fill, in the middle of winter, next to traditional fill for the owner to assess the viability and longevity of the product. The PHF is still strong and well bound after 2 years!
This busy entrance/exit way of a shopping complex was experiencing reoccurring potholes. Traditional pothole fill was not lasting and falling out within weeks of being installed. Gravel Lock undertook works with the Owner of Big Tomato Complex to install PHF to the existing potholes in the entrance way. This busy shopping centre experiences hundreds of car movements each day pulling in from an arterial thoroughfare which was becoming dangerous for the customers.
