- In areas of pavement where automobiles are frequently parked, a fuel resistant fog seal may be desirable to prevent fuel leaks from dissolving the top layer of asphalt binder. Consult a paving contractor about the use of any sealant.
- If unsure of subgrade condition, the design for "poor subgrade" should be used lessen the risk of premature failure.
- State Mix V can be used for driveways and thin driveway overlays.
- For steep driveways, consider using State Mix IV so that the driveway can be compacted without shoving.
- Design driveways with a minimum cross-slope of 2 percent (0.25 inches per foot). Slopes less than this are difficult to construct and may not prevent pooling of water during wet weather.
HAPI Pavement Note on Driveways |
The State and Counties all have requirements for working within their right-of-ways. If any driveway construction occurs within State or County right-of-way (which it often does) these requirements must be met. |
- Driveways should be compacted to a minimum of 90 percent TMD (Rice density). Lower levels of compaction may result in driveways that will significantly compact under a parked car load or scuff as a result of turning an automobile's wheels while it remains parked.
- Driveways should be constructed with HMA and not cold mix asphalt. Cold mix asphalt is typically used for emergency repairs and will often not stand up to even light automobile loads on hot days. Turning an automobile's wheels while it remains parked can considerably scuff cold mix asphalt.
- Where there is the possibility of recurrent vegetation growth, a quality commercial grade herbicide should be used.
HAPI Pavement Note on Driveway Paving Contractors |
A driveway paving project should be treated like any other major home improvement project. The State of Hawai'i Department of Commerce and Consumer affairs has some information on contractors, licensure and selection (http://www.hawaii.gov/dcca/pvl/areas_contractor.html). If you would like additional advice on hiring a driveway paving contractor HAPI members are glad to provide you with a quote or contact information for a known reputable contractor. |
