These guys are good! We asked to resurface our 70' driveway and to redo the drainage. It was all accomplished in one day at an acceptable price. Derek has our unqualified endorsement.

Frequently Asked Questions About Mainline Paving & Masonry
What is the best surface for a driveway?
The most durable driveway surfaces include asphalt, concrete, and pavers. While many paving companies specialize in a single type of surface, Mainline Paving & Masonry offers expertise in all three and more. For personalized advice on the best surface for your specific needs, we encourage you to contact one of our experts. As trusted driveway contractors in Gaithersburg, MD, we're committed to providing you with the best solution.
How thick should driveway paving be?
The thickness of driveway paving varies based on several factors. For asphalt driveways, the National Asphalt Pavement Association recommends a combination of approximately 95% stone, sand, or gravel bound with asphalt cement. Residential driveways typically require two to three inches of asphalt, with three inches necessary for driveways that will bear large trucks or heavy equipment. A proper foundation is crucial, with six to eight inches of granular base aggregate underneath the asphalt. At Mainline Paving & Masonry, we ensure that every driveway we construct has the appropriate thickness and foundation for long-lasting durability.
Is it fine to pave over an existing driveway?
Paving over an existing driveway is possible, but it depends on the structural integrity of the current surface. At Mainline Paving & Masonry, we carefully assess each driveway to determine if an asphalt overlay is a suitable solution. When appropriate, our contractors apply a tack coat to the existing asphalt surface to ensure proper adhesion of the new layer. For more information about this process or to discuss your specific driveway needs, we invite you to contact us.
How long should you stay off the driveway after paving?
Generally, a newly paved driveway requires 24 hours before it can be used. However, during periods of very warm weather, we recommend waiting 48 hours as the asphalt surface cools more slowly. For more detailed information about our paving services and aftercare instructions, please don't hesitate to contact Mainline Paving & Masonry.
How does the weather affect the asphalt curing process?
Weather conditions significantly impact the asphalt curing process. Extreme cold can prevent proper binding of the asphalt, while extreme heat may cause new asphalt to melt, slough, or bruise, impeding proper curing. Many driveway and parking lot issues can be traced back to problems during the curing process. At Mainline Paving & Masonry, we carefully consider weather conditions to ensure optimal asphalt installation and curing.
