Asphalt Slurry Seal, Micro-Surfacing, Slurry Coat — DRYCO

Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives, and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway. Slurry seal is very economical and extends the life of pavement up to 7 years.

HMA Mix Types | Washington Asphalt Pavement Association

Stone matrix asphalt (SMA), sometimes called stone mastic asphalt, is a gap-graded HMA originally developed in Europe to maximize rutting resistance and durability (Figure 2 and 3). The mix goal is to create stone-on-stone contact. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly reduces

How much does density matter? | Asphalt magazine

The normal target in-place density on a "dense" hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result. These may be in the form of premature oxidation

Studded Tire Information - Pavement Interactive

The typical studded tire (see Figure 1) is a winter tire with between 60 and 120 inserted small metal studs. These studs are usually made of tungsten carbide (an extremely hard metal), weigh 1.7 - 1.9 grams each and protrude about 1.2 - 1.5 mm from the tire surface. Studs are made by embedding a small metal "jacket" into the tire then

Asphalt Durability - Pavement Interactive

Asphalt durability is a measure of how asphalt binder physical properties change with age (sometimes called age hardening). In general, as an asphalt binder ages, its viscosity increases and it becomes more stiff and brittle. Age hardening is a result of a number of factors, the principal ones being (Vallerga, Monismith and Grahthem, 1957 [1
