Thin Overlays

Types of Thin HMA Surfacings • Dense-graded mixes - Continuously graded, Superpave - High Performance Thin Overlay (HPTO) • Open-graded mixes - 15-22% voids, fibers and polymer or crumb rubber - Used to reduce splash and spray, improve high speed friction and reduce tire noise • Gap-graded systems - SMA and SMAR mixes (95mm & 125mm) - Ultra-Thin systems (Novachip).

Street Improvement Project

This project includes mill and overlay, Ultra-thin Bonded Asphalt Surface (UBAS) and various concrete repairs Mill and Overlay A mill and overlay removes the top two to three inches of the asphalt street Crews then overlay new asphalt Milling removes the old surface and helps to.

Design and Construction of Ultra Thin Overlays as an

Thin and ultra thin overlays are asphalt mixtures that are placed over existing pavement structures to as a preventive maintenance treatment used to extend the pavement’s service life, protect the pavement structure and restore its skid resistance In the context of this.

HMA Ultra-Thin

But a thin overlay of hot-mix asphalt - such as HMA Ultra-Thin - not only provides a new pavement surface for a fraction of the cost of starting over, it's the only preventive maintenance technique that adds structural value to the roadway, while helping to extend a pavement's service life.

Asphalt Paving

Ultra-Thin Overlay At ASI, we want your roadway or parking lot always looking good If your asphalt is starting to crack or has small puddles, an ultra- thin overlay may get the job done This process involves removing one inch of the existing asphalt and repaving a new 1” wearing course It brings a nice finish to the existing parking lot.

Thin Asphalt Overlays

IS - 135 Thin Asphalt Overlays for Pavement Preservation Thin asphalt overlays are popular approaches to pavement preservation because of their ability to provide improved ride quality, reduce pavement distresses, maintain surface geometrics, reduce noise levels, reduce life cycle costs and provide long-lasting service.

Asphalt vs Concrete: Which Is Best?

The main types of concrete overlays include: White topping; Ultra-thin white topping; Bonded overlay; Unbonded overlay Disadvantages of Concrete Roads Typically, the paving cost for concrete is a little higher than the paving cost for asphalt.

4133 Ultrathin Bonded Asphalt Wearing Surface

An ultra-thin (< 1”) bonded asphalt wearing surface (UBAWS) is a hot mix asphalt (HMA) overlay placed over a heavy asphalt emulsion layer or membrane The thickness ranges from 1/2 in to 3/4 inch The table below lists the minimum lift thickness for each UBAWS type based on the nominal maximum aggregate size allowed for the mixture.

Ultra Thin Bonded Asphalt Overlay

This work consists of constructing an ultrathin bonded asphalt concrete wearing surface The ultrathin bonded asphalt concrete consists of application of a warm polymer modified asphalt emulsion followed immediately with a 5/8 inch (16mm) minimum hot asphalt concrete overlay 87402 Materials Conform to the following requirements:.

Tech Brief: The Use of Thin Asphalt Overlays for Pavement

A thin asphalt overlay will improve smoothness more than a chip seal and the small macrotexture of the thin asphalt overlay surface will generate less tire-pavement interface noise than the chip seal These benefits are a part of the value of using a thin asphalt overlay.
