Asphalt sealcoating involves applying a protective layer of coal tar or asphalt emulsion to paved surfaces, which includes thorough cleaning and crack filling. This process significantly extends the lifespan of your asphalt driveway or parking lot by preventing oxidation and water penetration.
Choosing Diamond Asphalt for your Longmont property means partnering with a contractor who understands the local conditions. We're not just working near Longmont; we're actively engaged in the community, whether it's paving a new driveway near McIntosh Lake or repairing a parking lot in the Prospect New Town neighborhood. Our proximity allows for quick response times and efficient project management, because we spend less time commuting and more time working on your site.
Our process involves more than just laying down asphalt. We begin with a thorough subgrade evaluation, because a stable foundation is critical for preventing premature cracking and settling. We use high-quality, locally sourced aggregates and binders, which means the asphalt mix is optimized for Colorado's climate fluctuations. For new installations, we typically specify a minimum of 2-3 inches of compacted hot-mix asphalt over a properly prepared base, ensuring structural integrity and longevity. We also pay close attention to proper drainage, designing slopes and grades to prevent water pooling, which is a common cause of asphalt deterioration.
When you work with Diamond Asphalt, you can expect clear communication about each phase of your project. We provide detailed proposals outlining material specifications, compaction requirements, and project timelines. Our crew arrives on schedule, works efficiently, and maintains a clean work site. We perform a final walk-through with you, ensuring every aspect of the asphalt application meets our stringent standards and your expectations for a durable, functional surface.
A newly installed asphalt driveway in Longmont, CO, typically lasts 15-20 years with proper maintenance. This longevity depends heavily on the quality of the initial installation, including adequate subgrade preparation and compaction, and the thickness of the asphalt layers. Regular sealcoating every 2-3 years and prompt repair of small cracks can significantly extend this lifespan by protecting the surface from UV radiation and water penetration, which are major contributors to asphalt degradation.
A new asphalt driveway in Longmont typically takes 2-3 days to cure sufficiently for light vehicle traffic, and about 6-12 months for a full cure. While you can usually drive on it after 48-72 hours, it's crucial to avoid heavy vehicles, sharp turns, or parking in the same spot for extended periods during the first week. The asphalt continues to harden and strengthen over several months as the oils oxidize and the material fully compacts, which means being gentle with it initially will prevent ruts and indentations.
The best time of year for asphalt paving or major repair in Longmont, CO, is typically from late spring through early fall, specifically from May to October. This period offers consistently warmer temperatures, ideally above 50°F (10°C), which are crucial for the hot-mix asphalt to remain pliable during placement and to achieve proper compaction. Paving in colder temperatures can lead to premature cracking and reduced durability because the asphalt cools too quickly, preventing adequate bonding and compaction.
