WHAT IS HOT MIX ASPHALT?
Also known as blacktop, asphalt pavement or hot mix pavement. Asphalt is an engineered mixture of aggregates : Crushed stone, Gravel, Sand and Liquid Asphalt.
WHAT IS THE DIFFERENCE BETWEEN BINDER AND TOP COAT?
Binder, or base coat, is known as the load bearing coarse and typically contains 3/4” stone. It is the foundation for the upper pavement structure. It must offer excellent bearing capacity, be capable of withstanding a broad range of different climatic conditions, and remain functional over several decades.The Top coat, or finish, typically contains 3/8″ stone and is known for the smoother finish which is applied over the binder coat.
HOW THICK DO YOU LAY THE ASPHALT?
Asphalt thickness is engineered at the time of your estimate. Asphalt Engineering uses a standard platform for residential paving of 1.5” base and 1.5” top coat after compaction. The thickness is ultimately engineered taking into consideration location, saturation, and what kind of stresses will be put on the pavement. Commercial projects tend to have a thicker base coat application as they often have regular heavy vehicle traffic.
WHAT IS PRE-COMPACTION, POST-COMPACTION, and VIBRATORY ROLLING?
Pre-compaction measurements are the inches of asphalt laid on your driveway prior to compaction. Post compaction is the measurement of the asphalt after being rolled with a vibratory roller. For example 2” of asphalt pre-compaction would be 1.5” after compaction.Vibration is the conventional method of dynamic compaction using vertical forces. It causes the surface to vibrate in rapid succession so that the aggregate particles re-arrange to a denser position. Without a vibratory roller proper compaction can not be obtained.
HOW SOON CAN I DRIVE ON MY DRIVEWAY?
You must stay off your driveway with vehicles and equipment for one week. After the first week you may use your new driveway to go in and out of the garage, but you should refrain from parking on your new driveway for 14-20 days. Parking in different areas of the driveway for the first 6-12 months will help prevent depressions in your driveway.
DOES YOUR ESTIMATE SHOW TONNAGE, INCHES OF ASPHALT POST-COMPACTION, and PITCH NOTATIONS?
Water can be the number one cause of driveway failure if flow and run off is not properly designed and managed. Asphalt Engineering performs all of their estimates using a transit compass to determine proper pitch “heights/elevations” and water run off points which are noted on your diagram. On projects with drainage issues the installation of pvc pipes from downspouts, catch basins, french drains, and dry wells may also be recommended. Asphalt Engineering believes in full disclosure by including on your estimate the tonnage and inches of asphalt to be used. Photos of your property are kept on file to ensure clear communication between the estimator, office staff, and paving crew.
DO YOU HAVE FULL LIABILITY AND WORKERS’ COMPENSATION INSURANCE
As a homeowner you can be held personally liable if an injury or accident were to occur on your property and the contractor is not properlyinsured. Asphalt Engineering carries full liability insurance and our employees are covered under workers’ compensation insurance. Copies of these policies are available to the customer upon request.
IS ASPHALT ENGINEERING IN GOOD STANDING WITH THE BETTER BUSINESS BUREAU?
Absolutely, YES! In this industry there are a lot of “fly by night” companies that will promise the world and in the end not deliver. It is important as an educated consumer to check local review sites to see what the contractor’s past customers have to say.
