Before applying  ECOROADS® , make sure that structural materials which are planned for use in construction of the road base have a gradation mix (size distribution) that will result in good load bearing values and contain approx. 15% to 30% non-granular fines (-200 mesh size and cohesive in nature). Prior to construction, field testing was necessary to determine suitability, and upon completion of testing, excellent results were obtained.  Some clays and “fines” are silty in nature and are not useful for road construction.  Also, excessive fines can cause problems as a result of high plasticity and/or low load bearing value.

ECOROADS® can be used effectively over a wide range of  geological areas and soil gradation mixes (aggregate sizes). To achieve effective stabilization, materials containing approximately 20% cohesive fines (non granular) have been found to be a satisfactory target. However, excellent results have been achieved outside this range. Additionally the soil should contain a wide range of material sizes to provide shear strength and internal friction which increases load bearing values.

ECOROADS® has proven useful over a wide range of soil types. This range continues to expand  as ECOROADS® is used in more diverse locations throughout the world.

STEP 1

                                                                                 

Rip the surface by using  grader , rippers or soil mixer to a minimum depth of 7-8 inches and then windrow the loose material.  If the road requires greater depth, work the material in the lifts.  Check the overall gradation of the material to insure it is within the design limits.  

                           

Dilute ECOROADS® with water in a water tank. For each 25m3 of the road base material add one litter of ECOROADS® to the amount of water that should be calculated to obtain optimum moisture. Spray both the bladed surface and the windrow to obtain optimum moisture.

STEP 2

STEP 3

                                                                             

Mix the ECOROADS® treated material in a windrow using a grader blade or soil mixer, working the soil mix back and forth to blend in the applied ECOROADS® from water tank.  If the material is too wet, blade longer to make it dryer.  If too dry, add water without ECOROADS® to bring the material up to optimum moisture.  After thoroughly mixing spread the material to grade.  Depending of the weather conditions, treated soil mix can be left in windrow over night to allow complete moisture absorption.  This will result in better compaction with less effort.Blade treated soil mix to create road level and crown surface.  If your soil mix dries too quickly, spray surface again with diluted ECOROADS®.

  

Preferably use heavy compactors (12-18 tons) with pneumatic roller or vibrating plate compactor. Vibratory rollers may be used for the first and second passes, however further compaction should be done without vibrator action to avoid cracking and obtain maximum density.

STEP 4

After 72 hours of drying with normal dry weather, the road is ready for use or for application of any desired topping, such as asphalt or other surface coating. To achieve better bonding with applied topping materials, it is necessary to moisten the surface by spraying diluted ECOROADS® with a dilution rate at one to ten thousand (1:10,000).
