SCHEDULING OF WORKS
SCHEDULING OF WORKS
Objective
Work planning enables infrastructure network managers to determine the required interventions over a given period, including their type (light, medium, or major maintenance) and their distribution across the entire surveyed network, in order to maintain it in a condition suited to its use (freight or passenger transport).
This service also provides a global estimate of the budget needed for maintaining the network.
Ainsi, cette prestation permet de définir de façon globale le budget des gestionnaires pour l’entretien de leur réseau
How?
To deliver this service, we rely on an audit of the infrastructure network.
This involves collecting data on the network (primarily a survey of pavement defects). These data provide insight into the network’s condition and allow it to be rated according to the manager’s scale (e.g., very good, good, poor, very poor).
Based on this rating, maintenance needs are defined (e.g., light, medium, major) and tailored to each manager’s requirements.
WORKS PRIORIZATION
PRIORISATION DE TRAVAUX
Objective
Once work planning is complete, it may be necessary to establish a priority order for the works over a given time frame (typically between 5 and 10 years). This process is known as work prioritization.
How?
To prioritize works, we base our decisions on the work plan and determine the order and type of interventions over several years. To achieve this, we establish a priority scale (defined in collaboration with the infrastructure network manager), typically based on pavement condition, traffic levels (including the presence of heavy vehicles), and the chosen maintenance strategy for the network. We present the advantages and disadvantages of each approach so that the project owner can make an informed decision. The two most common strategies are:
Curative strategy: Prioritize the treatment of the most deteriorated roads, with the risk that less deteriorated roads may continue to degrade.
Preventive strategy: Focus on moderately deteriorated pavements, while delaying treatment of the most degraded ones.
Effective communication between the infrastructure manager and our team is key to ensuring that prioritization aligns with the network’s needs.
PAVEMENT STRENGHTHENING STUDIES
PAVEMENT STRENGTHENING STUDIES
PAVEMENT STRENGTHENING STUDIES
Objective
At the scale of a highway section, in addition to a pavement condition survey, further in-situ investigations (coring, curvature radius, deflection measurements, radar, etc.) and laboratory testing (material testing to assess mechanical properties) enable us to gather as much information as possible to determine the condition and behavior of the pavement.
PAVEMENT DESIGN
PAVEMENT DESIGN
Objective
At the scale of a highway section, following a strengthening study that provides an optimized diagnosis and identifies the causes of pavement distress, we determine, verify, and optimize construction solutions through a calculation and modeling phase: pavement design. To achieve this, we rely on the recommendations of the NF P 98-086 standard (Structural Design of Pavements), as well as the strengthening guidelines published by Cerema and IDRRIM.
RECOMMENDATIONS FOR ADDITIONAL TESTING AND DATA ANALYSIS
RECOMMENDATIONS FOR ADDITIONAL TESTING AND DATA ANALYSIS
Objective
As part of a diagnostic service, whether for a strengthening study or for work recommendations, we may recommend additional testing and/or data analysis to reduce assumptions and refine our conclusions.
