The installation of a new driveway can be one of your largest home improvement projects, so you should expect the best quality from your contractor. Utilizing proper construction methods, a common driveway in New England should last up to 35 years, with proper maintenance and care. There are several steps involved in the removal and replacing of a pavement structure, and each step is crucial to the long term success of the asphalt. If any procedure during the installation process is done short of just what is required by industry standard practice, it will greatly decrease the durability and life expectancy of the driveway. As one of the most experienced residential asphalt paving companies in Rhode Island ( RI ) and nearby Massachusetts ( MA ), here is what you will receive when contracting with Nu-Look Asphalt.
Step #1: Excavation of existing material.
An asphalt structure is only as good as what's underneath it. Paving over soft ground or on top of damaged asphalt will surely cause the new pavement to crack and fail. It is in the preparation stage that the future success is set. As we state in all of our estimates, all existing asphalt or unusable current driveway material will be dug out and removed from the job site. In many cases, we need to dig down several inches if we are removing a severely failed surface, with buried rocks or soft material. We will always contact DigSafe as required by law, to indicate the location of underground utilities, even though we seldom need to excavate as deep as these structures usually lie.
Also, in most cases, paving over your existing full depth driveway is not a good idea as it doesn't allow us to correct sub base concerns. If there is significant cracking, they will likely reflect upward into and through the new asphalt within a short time period. Concrete can never be paved over with asphalt. We are well equipped with excavation equipment, skid steers, and dump trucks to haul away this material. It is always best to remove and dispose of it all.
Step #2: Installation of base gravel and grading of surface.
The proper installation of the base of material beneath the asphalt driveway provides the foundation for the strength, pitch and durability of the overall structure. We use an average of 4" of recycled asphalt product (R.A.P.) when preparing most residential driveways. This product, most often spread by a skid steer then rolled, is engineered specifically to be laid beneath asphalt, compacts very well, and is set at the proper grade to allow for sufficient water drainage. Grading the gravel base correctly allows for easier asphalt laying to occur later. When necessary, we will use a laser level or transit to ensure pitch, so that water is channeled in the most appropriate direction when the driveway has little slope. The gravel is then rolled with a vibratory roller, and next it is gone over once again with a hand compactor. The surface is now ready to be paved. Our goal is to achieve a pitch of 1.5%, or 1.5 inches over a ten foot span. At this angle, water will flow slowly in the desired direction and ultimately off the surface. If your driveway is very flat or pitches downhill toward the garage or house foundation, we may suggest that you install a drain to prevent water from flowing toward your structure. This can usually be avoided with proper grading of the gravel, but in some cases, it can be necessary. Feel free to ask your estimator about this possibility.
Step #3: Purchase and laying of hot mix asphalt.
Once the surface is properly prepared, Nu-Look sends its fleet of dump trucks to the nearest asphalt mixing plant to purchase the freshly batched hot pavement mix. Having the proper trucking capacity allows us to remain operative and productive, and minimizes material cooling and down time. Our driveway paving crew typically includes 5 to 6 experienced men on the job, including the company owner. In most cases, the asphalt is laid in two levels, or lifts. The first lift is called a binder course, and consists of a larger stone with greater strength. The second lift, or top coat, has a finer stone and provides a clean finished look. Nu-Look uses state of the art paving equipment in order to provide the highest quality finish.
Step #4: Compaction and the finished product.
A most important and final step in the paving of your driveway is the compacting process. Without proper compaction, the asphalt structure will not hold together and endure season after season. Upon the laying of each lift of asphalt, as with the base gravel, the surface is rolled with a 3 to 5 ton vibratory drum roller, and then further compacted with a plate compactor. Our edges are hand tamped to provide a 45° angle, providing the necessary strength to support vehicle weight. When your driveway abuts an asphalt street, the joint is always sawcut out so the two surfaces meet flush underground, providing the full depth of asphalt in all areas. A sure way to break off the edge of a pavement structure is to "skim coat" it to a thin layer over the neighboring surface. This results in asphalt that is too thin to support sufficient weight, as well as allowing snowplows to lift it up. Once the process is completed, your Nu-Look installed driveway will be durable, attractive, and will improve your property's value. Again, as one of the top rated residential asphalt paving companies in Rhode Island ( RI ) and nearby Massachusetts ( MA ), when contracting with Nu-Look, you can expect the best.
