Pavement Design and Testing

ParklandGEO usually undertakes pavement design as part of municipal infrastructure or industrial/ residential land development projects; and provides designs based on pavement assessments for reconstruction/ upgrade projects on existing roadways. We have provided designs for flexible asphalt concrete pavements (ACP), rigid Portland cement concrete (PCC) pavements, roller compacted concrete (RCC) pavements, interlocking paver block/ slab pavements and granular pavements including pads and resource roads on muskeg.  

 

 

ParklandGEO has considerable experience undertaking pavement assessment and failure investigations on industrial, urban road and highway project sites.  In Western Canada most hard surface roads are constructed with ACP.  We are very familiar with Pavement Management System evaluations for ACP, including structural assessments based on deflection testing, visual condition assessments, ride comfort indexes, etc.  While we subcontract major deflection testing projects (i.e. FWD or Dynaflect), we have the ability to undertake localized pavement deflection testing for smaller projects using Benkelman Beam equipment.  We have experience using a number of subgrade, base and pavement reinforcement options including: geotextiles, geo-grids, geo-cells, cement stabilized subgrade, cement stabilized base (soil cement), Full Depth Reclamation (foamed asphalt base), Deep Asphalt Base Replacement, ACP layers with Polymer Modified Performance Grade Asphalt Cement and composite pavements including PCC pavement layers. Our innovative knowledge in pavement technology helps us to provide our rehabilitation project clients with optimized pavement designs and reduced life cycle costs.  

 

 

Construction testing on pavement projects overlaps with our materials testing services.  However, pavement testing requires specialized training and experience to help prevent future problems that include premature cracking, rutting, and or pavement breakup due to poor subgrade/ base support, poor mix materials or design and/or construction issues.  There are a number of things to take into account when considering pavement design and construction in Western Canada, such as which materials to use; what type of pavement option and design will best suit your project; and how our harsh winters will affect your pavement, since freezing and thawing contribute to pavement damage, potholes and cracking over time. ParklandGEO engineering and testing personnel have many years of years dealing with these issues on pavement projects.  We can provide material acceptance testing, mix design reviews, mix performance testing, sample collection and testing of field materials, along with the documentation of those field test results so that our projects run smoothly and remain on schedule.

 

ParklandGEO is pre-qualified by Alberta Transportation for mix designs and asphalt testing.  We have labs and personnel that are CCIL certified for testing of hot mix asphalt and concrete aggregates, asphalt concrete pavement and Portland cement concrete for PCC and RCC pavements.  We can provide testing services for both Marshall Mix and SuperPave pavement designs; and we have several mobile field labs for testing both aggregates at gravel crusher sites and ACP on remote road and highway sites.
