The Evolving Road Landscape and PMS


Overview of Existing PMS Systems


Emerging in the 1970s, Pavement Management Systems provided a structured framework for optimising budget allocation for road upkeep. These systems empowered network managers to prioritise road maintenance, analyse the balance between budgetary constraints and network health and devise both short-term and long-term action plans.


A few notable contributions of PMS include:

  • Transitioning from sporadic maintenance planning to structured budgeting and systematic programs.

  • Establishing standardised assessment methods for consistent road condition evaluations.

  • Cultivating performance prediction models and formulating treatment selection benchmarks.

  • Championing the philosophy of "Sustainability through Preservation".

However, while PMS introduced game-changing improvements, they are not without their drawbacks:

  • They often rely on limited manual inspection road data, leading to patchy network coverage.

  • The quality of inspection can vary with individual inspectors or individual contractors, leading to data inconsistencies.

  • Treatment recommendations do not account for real-time changes or near-current pavement health states.

  • Performance prediction models necessitate regular updates which is not always available from infrequently collected field data.

Given the dynamic nature of roadways infrastructure today, an enhanced strategy is a pressing need.


Challenges in Contemporary Maintenance


Adverse effects of climate change, such as flooding, wildfires and extreme weather conditions, have significant repercussions on road infrastructure, causing issues like erosion and heat-induced damage. Road safety research indicates the need for smarter, technology-driven solutions to predict and proactively address these impacts.


Big vehicles are also no longer the preserve of the few. The trending preference for bigger cars like SUVs and the subsequent increase in electric vehicles (EVs) is another sphere of concern. These vehicles exert more pressure on road surfaces, thereby degrading them at a faster pace. It is imperative to consider also that EVs are typically heavier than conventional cars due to the weight of their batteries. This escalated vehicular weight coupled with the increased volume of these vehicles results in more rapid wear and tear of a road’s surface, hence, necessitating more frequent maintenance and potentially, reconstruction.


Moreover, while the need for road maintenance is on the rise, agencies often face budgetary and manpower constraints. The essence of the challenge lies in achieving more with less, enhancing maintenance ROI, and minimising unplanned repairs. Relying solely on manual inspections is not feasible due to time, financial and safety implications. Furthermore, the limitations of sparse LiDAR-based inspection methods often leave knowledge gaps about the true health of roads, let alone the issues relating to the significant costs of their use.


This current landscape underscores the importance of blending human expertise with technological innovations to usher in an era of smart, automated and proactive road upkeep – which is possible with the opportunities afforded by automated road condition assessments.


The Merits of Embedding Maintain-AI into the PMS Framework


The Genesis of Maintain-AI


Maintain-AI was birthed with a vision to maximise the utility of every maintenance dollar spent through AI-powered road asset management. Drawing from years of experience in engineering and digital innovation, the founders identified several gaps:

  • Existing systems struggled with scalability, often failing to provide comprehensive network coverage.

  • The quality of objectivity of inspections varied widely, affecting data legitimacy.

  • Limited budgets often resulted in deferred maintenance, escalating lifecycle costs, reducing.

  • Although recently developed LiDAR-based systems are accurate, their high cost, complexity and infrequent use limit their potential to make timely data-driven decisions.

To address these issues, Maintain-AI harnessed advanced AI and computer vision methodologies to devise an automated pavement condition survey system. This system, characterised by its frequent, unbiased and actionable data, signals a shift from reactive to proactive road asset management strategies.

Recent advancements like LiDAR-based systems are undeniably accurate, but their considerable expense and limited use gives rise to infrequent data collection and hinders their transformative impact on decision-making processes. Real progress in improving road maintenance resides in consistently assessing a road's current condition state to apply the most cost-effective treatments at the most opportune times. This strategic approach will revolutionise future road maintenance, resulting in major performance improvements and more efficient use of funding. This is why Maintain-AI was conceived.

As per our company's ethos, Maintain-AI is committed to delivering a near fully automated pavement assessment process to ensure consistent, objective and scalable data collection and analysis. This aligns seamlessly with our mission of maximising the value of every dollar invested in road infrastructure and why good roads should cost less.


The Technological Backbone


At its core, Maintain-AI employs an AI-based automated road inspection system that utilises high-resolution imaging from mobile phones, mounted to a vehicle’s windscreen, to survey road conditions. Key features of the automated road survey system include:

  • An easy to use App that captures video data of the pavement surface, even at highway speeds.

  • Proprietary AI algorithms, rooted in deep learning and machine vision techniques, that detect pavement defects like cracks and potholes.

  • A cloud-based data provision pipeline for deriving actionable insights.

This revolutionary approach allows for rapid data collection at a fraction of the cost of manual or LiDAR based surveys, with a level of objectivity more consistent than human inspectors. The platform autonomously generates reports detailing defect types and condition scores and other insights from the captured data set.


By transforming raw pavement data into actionable insights, Maintain-AI equips road authorities with the tools to make more informed decisions. Some of the standout benefits include:

  • Covering significantly more area of manual inspections at reduced costs.

  • Conducting surveys as frequently as users request and need, enabling early detection of potential defects.

  • Achieving consistent surface defect detection observations, that continues to improve with further adoption and analysis.

  • Providing unbiased data that is not influenced by human error.

  • Offering customisable maintenance planning information that can support available budgets.

Complementing PMS with Maintain-AI


Despite the evident limitations of existing PMS systems, many road agencies are hesitant to discard them completely. This is where Maintain-AI excels – it is designed to enhance and complement existing frameworks, ensuring a seamless integration.

For instance, condition data from Maintain-AI can be incorporated into PMS performance prediction models, refining the recency of available road condition data. Moreover, Maintain-AI's detailed defect analytics can be utilised by treatment selection modules to provide more consistent and frequent maintenance recommendations.


In line with FAIR principles, Maintain-AI ensures that this critical condition data is Findable, Accessible, Interoperable and Reusable, thereby adding another layer of robustness to your existing PMS systems.
