asphalt mixture design for porous ultra thin overlay

Thin Overlays - State

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 (9.5mm & 12.5mm) – Ultra-Thin systems (Novachip)

Thin Asphalt Overlays for Pavement Preservation

vation by thin asphalt overlays, materials selection and mix design, construction practices including quality control, and the performance history of thin asphalt overlays. Thin asphalt overlays as used in this guide are surface mixes of 1.5 inches or less placed on a …

Ultra Thin Asphalt Overlays | West Contracting

Ultra Thin Asphalt is a hot mix asphalt installed with a specialized asphalt paving machine. This machine is called a Bondtekk Paving Machine, a technology developed by Road Science. This paving machine installs "bonded pavements" which allow for superior asphalt strength of pavements and longer life spans in thinner asphalt layers (lifts).

Determination of Construction Parameters of Porous Ultra ...

To address the severe distresses of asphalt pavement, a new type of pavement maintenance treatment, porous ultra-thin overlay (PUTO) with small particle size was proposed. The PUTO has a thickness of 1.5–2.5 cm and a large void ratio of 18–25%. As a newly asphalt mixture, the structure characteristics differ from poor traditional pavement.

In this study, a kind of small particle porous ultra-thin overlay (PUTO) is proposed, which has a thickness of 1.5~2.5 cm and a large void ratio of 18~25%.[4], and combines the functions of the ultra-thin overlay and the porous drainage asphalt mixture. After the construction of PUTO,

Thin Overlay Guidelines

There are three "flavors" of thin overlays, each having unique qualities and applications (TABLE 1). These have a small nominal maximum aggregate size between the #4 and 3/8 inch sieves, and have a minimum asphalt content of 6.0 or 6.5 percent. The most popular of these is the thin overlay mix …

Asphalt mixture design for porous ultra-thin overlay ...

In this study, a porous ultra-thin overlay (PUTO) is proposed as a sustainable and environmentally-friendly asphalt pavement maintenance technology. In order to design the PUTO asphalt mixture, two high-viscosity modifiers and two blended asphalts were used to prepare the high-viscosity asphalt. Dynamic shear rheology (DSR) tests, 60 °C ...
