Understanding Pavement Degradation

All pavements, whether asphalt or concrete, are subject to degradation over time due to weather, traffic, and environmental factors. Understanding the causes of this degradation is the first step in developing an effective maintenance strategy. Identifying issues early will greatly assist in your pavement management efforts. The goal is to prevent costly repairs from occurring by catching and fixing minor problems before they escalate.

Common Causes of Pavement Deterioration

Water Penetration: Water seeps into cracks and joints, weakening the underlying base and sub-base. Freeze-thaw cycles exacerbate this damage, leading to potholes and pavement failure.
Traffic Load: Heavy vehicles and constant traffic put stress on the pavement, causing rutting, cracking, and deformation. Consistent use will wear the asphalt over time. Especially in areas with a high volume of trucks and large vehicles.
UV Exposure: Ultraviolet (UV) radiation from the sun causes the asphalt binder to oxidize, making the pavement brittle and prone to cracking. A yearly seal coat can combat this issue.
Chemical Exposure: Spills of oil, gasoline, and other chemicals can dissolve the asphalt binder, leading to surface deterioration.
Poor Drainage: Inadequate drainage systems allow water to pond on the pavement surface, accelerating deterioration and creating safety hazards.

By understanding these factors, you can proactively address potential problems and implement preventive maintenance measures to extend the life of your pavement. Regular inspections are crucial to identify early signs of deterioration and take corrective action before the damage becomes severe. Implementing a computerized maintenance management system (CMMS) can streamline this process.

Developing a Comprehensive Maintenance Plan

A well-defined parking lot maintenance plan is essential for preserving your pavement investment and minimizing long-term costs. This plan should outline routine maintenance tasks, inspection schedules, and repair strategies. A CMMS makes it easier to track maintenance requests and plan preventative maintenance.

Key Components of a Maintenance Plan

Routine Inspections: Schedule regular inspections (at least twice a year) to identify cracks, potholes, drainage issues, and other signs of deterioration. Document your findings and track the condition of your pavement over time.
Preventive Maintenance: Implement preventive maintenance measures, such as crack sealing, sealcoating, and line striping, to protect the pavement from damage and extend its lifespan. The frequency depends on traffic and environmental conditions.
Repair Strategies: Develop repair strategies for addressing various types of pavement damage, including pothole patching, asphalt overlays, and concrete repairs. Ensure you have a budget allocated for these repairs.
Budgeting and Resource Allocation: Allocate sufficient funds and resources for maintenance activities. Prioritize tasks based on their impact on safety, pavement condition, and cost-effectiveness.
Documentation and Record Keeping: Maintain detailed records of all maintenance activities, including dates, costs, materials used, and contractor information. This information will be valuable for future planning and budgeting.

Example: Imagine a facility manager noticing hairline cracks during a routine inspection. By promptly sealing these cracks, they prevent water from seeping into the sub-base, potentially saving thousands of dollars in future repairs. Ignoring these cracks could lead to significant pothole formation and costly reconstruction. A CMMS can help schedule and track these inspections.

Essential Maintenance Procedures

Various maintenance procedures can help preserve your parking lot's integrity and appearance. Prioritizing these procedures based on the extent of damage present in your pavement management is essential. Regular cleaning can also prevent drainage issues and ensure proper operation of your facility.

Crack Sealing and Filling

Crack sealing prevents water from entering the pavement structure through cracks. Use a hot-applied sealant for best results. Clean the cracks thoroughly before applying the sealant.
Crack filling involves filling larger cracks with a flexible filler material. This prevents further cracking and extends the pavement's lifespan.

Sealcoating

Sealcoating protects the asphalt surface from UV radiation, water penetration, and chemical spills. Apply a sealcoat every 2-3 years to maintain a protective barrier.

Pothole Patching

Potholes should be repaired promptly to prevent further damage and ensure safety. Use a cold-mix asphalt patch for temporary repairs and a hot-mix asphalt patch for permanent repairs. Proper compaction is crucial for a durable patch.

Line Striping and Marking

Line striping and pavement markings are essential for safety and traffic flow. Restripe lines and markings as needed to maintain visibility. Use durable, reflective paint that meets local regulations.

Drainage Maintenance

Drainage systems should be cleaned and inspected regularly to ensure proper water flow. Remove debris and sediment from catch basins and drainage channels to prevent clogs and standing water. Addressing drainage problems promptly helps prevent pavement deterioration.

By performing these essential maintenance procedures, you can extend the life of your parking lot, improve safety, and enhance its appearance. This should be an on-going part of your preventative maintenance program. Also be sure to adhere to all regulatory compliance requirements while performing these procedures.

Best Practices and Common Mistakes
