Preserving Pavement Where It Matters Most
Nearly six months ago, Mayor Peter Carlisle joined the Department of Facility Maintenance and the Hawaii Asphalt Pavement Industry to demonstrate several pavement preservation methods the city will evaluate as part of its effort to improve road/parking lot conditions.
The goal of pavement preservation is to treat a road/parking lot that is in good condition to extend the life of the asphalt pavement.
As Mayor Carlisle put it, he would like to “protect our roadways to help stop potholes and other problems before they even start.”
Since then, the city has been using these methods to better Hawaii’s asphalt.
Alakona continues to slurry in the Mililani Mauka area
A slurry seal is a mixture of aggregate, emulsified asphalt (cationic quick set emulsion, CQS-1h), fillers and additives. This surface treatment can be used on newer or older pavements. It will fill the surface cracks, stop raveling and improve skid resistance. Additionally, it will waterproof the surface and reduce oxidation deterioration. This product becomes the wearing surface and “slave” to vehicular traffic.
The Department of Parks and Recreation has started using pavement maintenance including two projects at Hanauma Bay. It applied hot crack filler and two coats of OptiPave Plus sealer. The upper parking lot was applied by Alakona and the lower parking lot by Walker-Moody Asphalt Maintenance.
Crack filling is the most basic of pavement treatments. Once moisture penetrates the asphalt, it will deteriorate the underlying layers, eventually causing failure. SealMaster Hawaii provides coldand hot-pour materials that can be used as a first defense against pavement deterioration by stopping moisture.
A seal coat is an application of asphalt emulsion — often mixed with coarse angular sand — to an existing asphalt surface. In addition to providing a protective barrier to stop water penetration, MasterSeal Ready-To-Use or OptiPave Plus sealers will also protect against oxidation, oils and gases, and it will beautify your asphalt by providing a uniform black color to the surface.
The Department of Education (DOE) also started maintaining pavement recently at Pauoa Elementary School. The application of a seal coat on this project will prolong the investment lifetime. The project also involved applying hot crackfiller and two coats of MasterSeal Ready-to-Use sealer.
All products used in the demonstration and by the city, District Performance Review and the DOE are available at SealMaster Hawaii. These pavement maintenance techniques have been used in the private sector for a number of years and SealMaster is happy to provide its products to the city, county and state.
For more than 40 years, quality-driven contractors have relied on SealMaster, the most recognizable name in pavement maintenance in the world. With everything under one roof, contractors save valuable time and money on products, tools and equipment needed to do the job right.
