Pavement construction is one of the major uses of multi-layered surfaces that include roads, footpaths, and corridors of transportation. Pavements play a critical role in serving structural purposes to carry immense weights while ensuring smooth movement through adverse environmental conditions.
Pavement construction requires the layering of different building materials. Pavement construction is an important aspect of building as it enhances the strength and longevity of the building. This section encompasses the development of different material layers with carefully designed pavement structure.
It is important for distributing vehicle load and maintaining pavement integrity. With the right pavement design and surface dressing supported by well-formulated successive layers of materials holding different physical properties, smooth and safer pavement with a long service life can be built.
Public infrastructure projects require process-wide domain knowledge and precision-led planning. Pavement construction, being one of the key infrastructure development projects that is built for seamless connectivity, road safety, and commuting value, needs specialized experts from the field with road engineering expertise and proven industry experience.
Pavement construction is one of the major segments of large public infrastructure development. A well-constructed road pavement is found to play a significant role in safe commuting. It also aids in the achievement of the greater goals of sustainable infrastructural development.
Here are the core practices and major drivers of pavement construction:
Subgrade refers to the natural earth that comes first as the base of pavement structure. In the process of subgrade preparation, compacting and stabilizing of the soil are integral parts that aim to strengthen the surface to meet structural requirements.
These layers are added to the pavement for even traffic load distribution and improved drainage. Here, strengthening materials like crushed stone and gravel are used to enhance the stability and integrity of the construction and prevent deformation and damage in due course.
The surface layer that is found at the top may have either a rigid component, like concrete, or a flexible material, like the material used on the surface of roads, which is called asphalt. This will provide a smooth surface that is also not slippery, thus allowing safe and convenient movement while protecting the surfaces underneath it.
By following proper drainage and quality control measures, water damage can be controlled. This involves regular quality checks and damage prevention practices at routine intervals. This allows pavements to meet design standards and retain their shape and structure.

Pavements are largely classified into two broad industrial categories - rigid pavements and flexible pavements - mainly driven by the collective influence of factors like composition, formation, and application. Let's explore these in detail:
On top of it, the main difference is created based on the elemental composition and structure. Rigid pavements are made of cement concrete and do not bend under the pressure of traffic and movement. Rigid pavements have high flexural strength, which allows them to distribute traffic loads across a large area. Rigid pavements are less susceptible to permanent stains from oil and grease compared to what happens in the case of flexible pavements. The lifespan of rigid pavements can be from 30 to 40 years. This timespan largely depends on the the maintenance practices and environmental factors.
Flexible pavements, on the other hand, are built with asphalt that can deflect to adjust to traffic or wheel load. This makes them less prone to deformation and damage. Asphalt pavements generally require less investment initially at the time of development, but require frequent reworks and upkeep, which adds to the cost of maintenance. Flexible pavements using asphalt layers are generally employed in heavy infrastructure projects such as highways, airport runways, and car parking areas. The usual lifespan of flexible pavements ranges between 10 and 15 years. However, the lifespan of such pavements can be extended up to 5 more years with regular maintenance.
Let's discover different issues and challenges faced in the process of pavement construction before diving deep into BIM's role:
Design fragmentation is one of the major challenges in pavement construction. It may hit because of disarrayed drawings, scattered information, and siloed workflows.
Inaccurate quantity estimates may result in material mismanagement and supply shortages in the process. This may lead to unstable and inefficient workflows.
Poor coordination can be the reason for clashes between functions and resources. This may adversely affect the process compliance and deliverability at all levels.
Project overheads can increase owing to hefty reworks, frequent change orders, interdisciplinary conflicts, and disorganized processes.
Construction delays can be caused by mismanaged resources. This may further be aggravated with faulty process frameworks and environmental disruption.
Improper performance monitoring may restrict project managers from tracking performance gaps and incompetencies and making informed decisions on maintenance and resurrection.
BIM or Building Information Modeling has a far-reaching role to play in restricting and overcoming challenges related to pavement construction. This is attributed to different facets of BIM-enabled construction practices that are supported by evolved digital capabilities and hyper-integrated technology processes powering pavement construction.
One of the prime advantages offered by BIM in overcoming challenges in pavement construction is precise construction design and workflow planning. By using BIM, it is possible to design 3D models of pavement structures, which can be applicable to various surface layers and courses, thus facilitating the implementation of the pavement geometry aligned with the needs of the particular pavement. BIM allows teams to identify design inconsistencies early in the process by conducting visual analysis and validation. Also, through BIM-enabled hyper-integrated tools, road construction and pavement engineering changes can be updated dynamically across all views and documents.
The road pavement is largely dependent on the topography, soil conditions, and drainage system. BIM facilitates the integration of geotechnical information as well as survey inputs from the actual location of the site to be analyzed for appropriate inspection planning for the pavement construction. With this, the existing ground condition can be visualized in the production model, allowing engineers to read and evaluate the subgrade behavior and material requirements accurately. BIM allows project authorities and functional teams to deep-dive into the site conditions and work on drainage systems to prevent water-related challenges and failures. Also, any potential risk zones and erosion issues across several layers can be identified and resolved early.
There are multiple disciplines and various functions involved in pavement construction. A project for pavement construction may include roadway design, drainage, utilities, lighting, and traffic systems coming together to serve the project plan and purpose. If the functions and workflows are not tuned in well and are not coordinated properly, different types of production clashes and process conflicts can arise. This may cause functional disarrays, process delays, and costly reworks. BIM allows project teams across functions to come together in close tandem to establish coordination between processes and components. This allows early detection of functional gaps and system conflicts and provides a cohesive framework for early issue resolution.
For pavement design projects, it is difficult to do material projection and estimation due to the varying land conditions, layer thickness, slopes, and alignments. BIM provides a collaborative, data-integrated design environment that allows teams to extract information on quantity to be applied across functions and phases, directly accessing quantity takeoff data from the model. With the precise calculation of asphalt, concrete, gravel, stiff plate, crushed aggregate, and earthwork volumes, the project operations get the right quality and adequate supply of material without hindering the workflow. This further restricts the chances of manual errors and provides reliable cost estimations during preconstruction.
BIM can be considered a potent tool in the simulation and analysis of construction processes. BIM can be considered an extremely immersive medium to project actual scenarios by portraying the processes of road pavement construction. This helps project teams to predict process challenges, navigating through diverse logistical and operational scenarios. These simulations can assess different factors of performance and compliance, including particle-to-particle contact, load distribution, drainage system, and constructability. With the help of BIM, project teams can work on design alternatives to optimize pavement quality and performance. Further, construction sequencing can be planned, ensuring any possible process lags and delays can be evaded before entering the construction phase.
Construction delays adversely affect project operations, leading to major system dysfunction and process halts. These delays are mainly caused by weak planning and unforeseen site conditions. BIM aligns the time dimension with 3D models to deliver 4D simulations for construction workflows. With the time-integrated functional models, project professionals are able to depict the construction plan and visualize processes in clear and objective sequences. This allows teams to standardize the delivery system and perceptively allocate resources to optimize output. Production schedules and timelines are clearly communicated and established throughout the system to avoid any gaps or conflicts.
Large infrastructure projects that are built for public transportation need to be designed to withstand pressure service situations and heavy traffic loads. This requires continuous quality correction and maintenance planning. In case of urban areas, which have to cater to an ever-increasing population base, centrally managed project lifecycle management across phases of implementation, upgradation, and expansion becomes highly crucial. BIM allows project development authorities and construction planning teams to create centralized digital asset repository for continuous maintenance and rehabilitation planning. This helps in efficient data inspection and condition assessment and allows professionals to plan maintenance proactively optimizing lifecycle costs.
Pavement construction is one of the major segments of road infrastructure development. Pavement construction involves complex material sourcing and layering. The process needs to be supported by multiple resources and needs to be served by structured planning and detailed visualization. BIM comes into great importance so that teams can collaborate to create a plan seamlessly. BIM also helps in making accurate quantity estimates and comes handy in integrating cutting-edge technology to ensure accuracy of design and functional compliance. In addition to this, the importance of BIM lies in ensuring performance analysis and maintenance. This helps teams overcome different challenges posed by pavement construction projects.
Flexible pavement includes several layers of road construction material like hot mix asphalt, concrete, unbound granular layers, and a base course, which provide deflection and smoothness of movement. However, in the case of rigid pavement, the construction mostly aims at flexural strength that relies on the stiffness of concrete slabs.
Some of the major challenges commonly faced in the process of pavement construction include managing high traffic loads, providing for high axle loads and repeated loading, controlling deep rutting, managing maintenance costs, and ensuring a long design life for different road surfaces.
BIM allows a pavement engineer designing road construction projects to create models for multiple layers. Engineers can combine various materials to be precisely applied to different pavement sections. This distributes load across the pavement structure to offer the highest level of functional efficiency.
By using BIM, it is possible to automate the inspection and finalization of the material based on pavement construction needs that have been evaluated in detail using the tools for visualization and implementation. Using BIM, it is possible to assess the efficiency of different materials such as road asphalt, cement concrete, textured granular material, expansion joints, and angular particles for better efficiency and cost savings.
BIM can help engineers design pavement sections of multiple layers by considering the physical properties of base course materials and their application, upper layer materials and their application, unbound granular materials and their application, and so on.
