Why Consult Top Class Asphalt Paving Los Angeles Contractors

By Linda Ruiz


The ground, sub base, pavement layer, and blacktop are the most important parts of asphaltic paving surface. A strong pavement should be laid on a stable ground that has been excavated properly. In preparing your pavement installation, asphalt paving Los Angeles contractors will excavate the ground and remove any loose material and organic matter. With well-compacted and firm sub base, there comes the pavement layer.

It is also relatively cheaper to install compared to other materials like concretes. Contractors prefer using asphalt material because it last for long, and offers good performance. The hot mixture used to install asphaltic pavements is carefully engineered and it offers durable surfaces that can support heavy weight.

In laying down the blacktop, you should use a thickness of about 2 inches consisting of hot mix asphaltic material. The compacted thickness layer of aggregates should ideally be about three times the thickness of the hot asphaltic mix. Before you settle on the right contractor to handle your project, ensure a quotation of thickness of both aggregate and blacktop is provided.

Different contractors may use different thicknesses, and this is one aspect you should be keen on. Since the contractors want to save on cost, they might want to install thicknesses that do not meet the required standards or weight of loads. The cost of installing your driveways should mainly be derived from the thickness of sub base aggregate material and pavement.

To eliminate confusion and possibility of disputes, emphasize on getting quotation of the compacted thickness as well as the blacktop thickness. To ensure you have a durable parking lot and driveway, you can use a 2-inch hot mixture of asphaltic base course, which is then followed by about one and a half surface course. Another important thing is the drainage pitch. Because water will run on pavements, it is good that it is kept away from the surfaces and buildings.

If you allow water to remain on pavements, it may seep down and create problems. The pavements need to have a crown to edge sloping layout, which is about a quarter of an inch for every foot. The slope will ensure any water collecting on driveways is drained to the sides where it is again directed to drainage systems. For every 100 feet of driveways, it is recommended that you have an 18-inch fall.

The material, which you use, will determine the quality of pavements you get. While for the untrained eye, it may see all asphaltic pavements looking alike, the fact is that there are different materials of hot mix asphalt, which can be used. In driveways where no much strength is needed, Class 1 mix may be used and it works well for the base course.

The water collecting on blacktop is drained to edges of pavements where it is further directed to drainage channels to avert water damage. With a contractor who cares about the clients, you are able to lay down a pavement structure will can endure for decades. The contractors will use the right materials, equipments, skill, and practice. They also repair the driveways whenever defects occur.
