Analysis and Design of Pavement and Pavement Structures

Analysis and Design of Pavement and Pavement Structures

CRA's expertise program in pavement and pavement structure design is aimed at municipalities, property managers (properties include large parking lots), and contractors involved in paving and pavement structure construction.

This program allows us to obtain a pertinent and detailed evaluation of your pavement structure, and prepare re-construction and rehabilitation programs adapted to your specific requirements.  The program allows for rigorous follow-up during the implementation of the chosen solutions and helps to respect budgets allotted for the works.

The recommended approach is aimed at offering optimal solutions, focusing on the particularities of your project to maintain or improve the quality of the pavement structures (i.e., traffic lanes, parking lots, etc.) for which you are responsible.

Briefly, our services cover the following areas:

1. Analysis of pavement and pavement structures
   a. Qualitative statement (visual evaluation, general condition of the surface)
   b. Quantitative statement (rate and severity of deterioration, rutting, International Roughness Index [IRI])
   c. Statement on the mechanical characteristics (residual mechanical properties of the pavement structure and infrastructure: CBR Module, constraints, and allowable deformations)
   
   
2. Diagnosis
   a. Origin and cause of deteriorations by section and sector
   b. Priority of interventions
   
   
3. Presentation of the deteriorations on a plan with geodetic references
   
   
4. Solutions adapted and optimized according to existing structural characteristics
   a. Reconstruction using recycled materials
   b. Rehabilitation
    - Surface treatment -> stabilized foundation -> structural reinforcement
   c. Thin and structural re-surfacing
    - System to reduce cracking
   
   
5. Technical analysis and economical solutions
   a. Empirical and mechanically determined conception approach
   b. Rehabilitation program amortized over time
   
   
6. Quality control of procedures
   a. Laboratory analysis
   b. Quality control on site
    - Quality control of evenness -> Standard quality control of materials
   
   
7. Evolving with the times (retrieving results, supervision, and assessment)
