Learning Outcomes
Upon successful completion, the student will be able to:
Module 1 - Introduction: Potential Impact of Forest Roads on the Environment
- Describe the importance of forest roads.
- Describe differences between types of forest roads.
- Describe the general dynamics of landslides and surface erosion.
- Describe the potential impact of forest road construction on:
- Water quality.
- Fisheries.
- Wildlife.
Module 2 - Project Management
- Describe the steps involved in the road development part of Integrated Resource Planning.
- Describe other types of forest land occupation that will require pre-approval for a development plan.
- Describe three methods of project scheduling.
- Describe the components of a cost estimate.
- Describe the various forms of construction contract.
- Identify sources of equipment performance data.
Module 3 - Clearing, Grubbing and Stripping
- Describe falling techniques and the methods and equipment used to carry out clearing, grubbing and stripping operations.
- Discuss the use of woody material for corduroying.
- Describe and discuss the methods and equipment used to carry out log decking and removal, slash and debris disposal and the factors affecting the choice(s) between:
- Burning,
- Burying,
- Spreading within the right-of-way.
- Mark the appropriate minimum clearing width boundaries employing the Ministry of Forests typical roadway cross-section.
- Calculate the right-of-way width to be stripped to contain the road prism.
- Identify the site-specific conditions that can make 'overlanding' an appropriate construction technique.
- Describe the method(s) of 'overlanding.'
- Describe the equipment used in 'overlanding.'
Module 4 - Construction Survey
- Describe methods to establish sufficient ground control for construction accuracy, efficient, and cost effectiveness.
- Describe the different levels of ground control appropriate for site-specific conditions.
- Identify the components of road construction plans and profiles.
Module 5 - Subgrade Construction
- Describe the steps in forest road subgrade construction including appropriate techniques and equipment to minimize impact on the environment within given constraints imposed by terrain, geology and microclimate.
- Define the types and engineering characteristics of soil and rock materials.
- Describe road benching techniques and the criteria that call for each including:
- Balanced benching with stable side cast fill slopes;
- Full benching/end hauling;
- Full benching/dispersed or scattered fills on downslope side; and
- Full benching/stable side cast fill slopes.
- Describe why over-steepened sidecast may create problems.
- Describe field conditions that call for different rock work techniques and the appropriate equipment to use (i.e., rippers, rock breakers).
- Describe drill and blast techniques.
- Describe criteria used in selection of borrow pits and quarries.
- Describe excavation waste and the criteria used in disposal (storage sites).
- Define the natural angle of repose of various construction materials.
- Describe the requirements for rip-rap.
- Describe commonly used rip-rapping techniques.
- Describe the need for compaction.
- Describe the methods and equipment appropriate for compaction using different classes of material.
- Identify where compaction techniques would be appropriate during primary and secondary operations.
- Describe methods of fill placement for non-compacted fills.
- Identify problems with sidecast slopes and fills.
