Pavement Engineering

The key services provided by Pavement Engineering Section include:

Pavement Structural Design and Analysis

  • Developing pavement construction strategies and structural designs for new pavements.
  • Assessing existing pavement condition, determining feasible treatments, developing construction strategies and providing structural designs for rehabilitation or reconstruction, as appropriate.
  • Performing life cycle economic analysis of alternative pavement surfacing options.
  • Reviewing quality management system (QMS) drawings and tenders for highway construction projects.
  • Performing structural analysis for the remaining life at the current loading and due to a proposed special hauls.  
  • Determining structural enhancement requirements for upgrade to highway loading classification.
  • Performing pavement structural and material analysis for construction deficiencies and providing recommendations for remedial or resolution.  
  • Conducting overweight axle impact assessment and establishing the pavement damage fees for surfaced and gravel roads.
  • Reviewing pavement design and construction drawings for access from provincial highways to roadside developments.

Pavement Research and Assessment  

  • Assessing pavement for structural capacity and establishing the allowable seasonal load limits.
  • Developing and monitoring field/laboratory pavement and materials research projects to assess and implement new methods, materials, technologies and procedures.
  • Collaborating with national and international stakeholders in pavement and materials research/initiatives.
  • Representing Manitoba on different local, national and international committees related to pavement and materials. 

Vehicle Weights and Dimensions    

  • Assessing special vehicles permit requests.
  • Providing pavement damage fees for special vehicle configurations.
  • Evaluating and recommending the allowable axle and gross weights for different vehicles, tires and axle configurations including their seasonal limitations.
  • Participating in the development/update of vehicle weights and dimensions standards, policies, regulations and maps.

Management of Seasonal Weights Programs   

  • Updating the list of spring weight restricted highway sections and maps on an annual basis.
  • Monitoring thermistors and weather data, and assessing the pavement surface condition, and freezing and thawing trends.
  • Determining the start and end dates for the highway winter seasonal weights and spring road restrictions programs.
  • Preparing ministerial orders, and managing website, print media and social media updates.
  • Developing/updating the relevant polices and procedures.

Data Collection and Pavement Management   

  • Managing pavement strength and surface condition (distresses) data collection programs including scheduling, routing and quality assurance.
  • Processing pavement strength and surface condition data, and managing the databases.
  • Maintaining pavement management system including the development of condition/performance curves, determination of treatment effectiveness and forecasting network and sub-network conditions.
  • Determining the service life of different treatments to establish the optimum timing of application.
  • Selecting projects for preservation and rehabilitation programs for different sub-networks.
  • Reporting network level pavement condition including map development.

Construction, Specifications and Standards    

  • Designing/reviewing materials and mixes for pavements and bridges.
  • Developing design/analysis standards and guidelines through the evaluation of in-service pavements, materials and new developments.
  • Developing specifications for various materials/products and their construction.
  • Developing materials sampling and laboratory/field testing standards, and providing guidance to different stakeholders including regions, internal/external laboratories, suppliers, consultants and contractors.
