TECHNICAL:

 

Gravelock Technology reduces gravel consumption on gravel surfaced roads:

  • Save gravel

  • Improve Strength            

  • Reduce maintenance

  • Preserve clay cap

  • Reduced dust - improve safety

  • Reduces spring thaw effects

  • Reduces moisture susceptibility

  • Saves maintenance ‘budgets” and “money”

  • Reduces clay soil plasticity

Gravelock Technology locks in gravel into the road base and so reduces gravel loss, or reduces the need for gravel during initial construction by

enabling the use of local soils.

 

Gravelock improves road trafficability in wet weather and also helps to reduce dust in dry weather and reduces gravel loss.
 

Permanently Stable – Water Repellent Road Surfaces

 

Water is the number one enemy of roads, as it makes the roads soft.  Keeping the water out of the roads improves performance.

 

Construction can be integrated with road owner crews and equipment to help reduce outsourced costs.  Some Alberta MD’s have found that the payback from reduced maintenance costs is less than 18 months.

 

GRAVELOCK Technology uses a unique compound,  which forms protective, oily layers on the surfaces of soil and clay particles. It reduces ion mobility and ion exchange and simultaneously makes the clay material hydrophobic by eliminating the adsorption of water.

 

Technical Support

 

The expertise of one of the world’s oldest manufacturers of soil modifiers, together with the expertise of Pavement Scientific International Inc., one of Canada’s leading road construction technology companies and their modern high tech soils laboratory, combine their expertise to bring to you this cost saving technology. Pavement Scientific International Inc. after extensive research, both in their laboratory and in the field, have developed unique new laboratory procedures for their mechanistic and climatic design process for roads. for roads.  The performance of such treated soils is further enhanced during construction through the use of:

  • Unique, specially designed compaction equipment for  this type of construction provides significant deep kneading compaction.

  • Custom-built high pressure distributor trucks that improve the accuracy of the dosage and ensure uniform delivery into the soil.

  • High pressure injection application also ensures thorough mixing and distribution throughout the soil.

The result is a soil material in the road base that is much less sensitive to moisture, more workable during construction and can be compacted to a better particle-interlock state by equipment and traffic forces. GRAVELOCK Technology is  designed to increase the osmotic and matrix suction of typical clay based soils and it is this behavior that increases the strength and stiffness of typical clay based sub-grade soils. At the same time it locks in the gravel to minimize gravel loss.

  • Better particle-interlock means higher internal friction, improved strength and stiffness

  • Results in gravel preservation

  • Reduces clay cap loss or preserves clay cap of roads

  • It also causes soils to compact to greater density and less penetration of water.

  • The effect of GRAVELOCK on clay materials is permanent.

GRAVELOCK Technology is designed to improve the performance of local soils to reduce the amount of gravel required during construction and is suitable for a wide spec rum of materials ranging from clays and silty clays to  ravel. The soils must display some cohesive properties (i.e. contain clays).
