stone mastic asphalt pdf

Stone matrix asphalt (SMA) is a tough, stable, rut-resistant mixture that relies on stone-on-stone contact to provide strength and a rich mortar binder to provide durability [1]. Guidance Notes RD/GN/030 was issued in December 2001 introducing the use of stone mastic asphalt (SMA) as a surface course for heavily trafficked roads.

Stone mastic asphalt may be referred to by the acronym SMA. Approaching 2010, more frequent occurrence of rutting Lanham, MD 20706-4407 Tel: 301-731-4748 Fax: 301-731-4621 Toll free 1-888-468-6499 www.AsphaltPavement.org NAPA@AsphaltPavement.org Stone Matrix Asphalt1ST INTERNATIONAL CONFERENCE ON

The mix has a gap graded aggregate skeleton with The history of use of this material dates back some 30 years ago, and like every product stone mastic asphalt needs to be modified and adapted to conform modern materials and manufacture, as well as suit the various local conditions.

A rich mortar binder, the mastic portion to provide durability. Stone Mastic Asphalt (SMA) Hot Mix Types: means SMA 9.5, 12.5, and 19.0 mixes. Jan 1995; Guidance Notes RD/GN/030 was issued in December 2001 introducing the use of stone mastic asphalt (SMA) as a surface course for heavily trafficked roads. Stone Mastic Asphalt may be referred to by the acronym SMA. These objectives are usually achieved with a gap-graded aggregate coupled with fiber or polymer modified, and high asphalt … It is promoted primarily for use as a surfacing course with relatively high surface texture, low permeability and a high resistance to rutting. SP/SM10:140905 SPECIFICATION FOR DENSE GRADED AND STONE MASTIC ASPHALTS Page 3 of 30 1 General 1.1 Scope This specification covers dense graded and stone mastic asphalt for roads and related applications. REFERENCES 1.

Stone mastic asphalt with or without polymer modified binder is one of the new and innovative materials being used by road authorities in their challenge to provide cost effective solutions for roads carrying a continuingly increasing volume of commercial vehicles. Stone Mastic Asphalt (SMA) is widely used throughout the world as one of the preferred asphalt surfacings. Since then SMA has been extensively used as the surfacing layer on heavily trafficked bituminous carriageways in Hong Kong. Roadstone produces an Industrial and Commercial SMA for different applications.

The areas covered by this specification include: a) Asphalt materials b) Asphalt …

Roadstone produces an Industrial and Commercial SMA for different applications. The mix must be blended It is promoted primarily for use as a surfacing course with relatively high surface texture, low permeability and a high resistance to rutting.

The coarse texture tends to reduce the generation of spray during rain periods. Aggregates in SMA should resist degradation (fracture and abrasion) under high stresses at the contact points. Stone Mastic Asphalt Roadstone Stone Mastic Asphalt surface course materials are produced using high quality aggregates, bitumen and cellulose fibres.

Typical mix design will generally have 6.0–7.0% medium-grade asphalt cement (or polymer-modified AC), 8–13% filler, 70% minimum aggregate greater than 2 … Stone mastic asphalt (SMA) is a stone-on-stone like skeletal structure of gap graded aggregate, bonded together . Approaching 2010, more frequent occurrence of rutting The coarse texture tends to reduce the generation of spray during rain periods. Stone Mastic Asphalt Roadstone Stone Mastic Asphalt surface course materials are produced using high quality aggregates, bitumen and cellulose fibres. Abstract - The present study investigates the benefits of stabilizing the stone mastic asphalt (SMA) mixture in Since then SMA has been extensively used as the surfacing layer on heavily trafficked bituminous carriageways in Hong Kong. The Industrial SMA is for more heavy duty requirements with larger traffic

Stone Mastic Asphalt [SMA] mixtures rely on stone-to-stone contacts among particles to resist applied forces, and permanent deformation.
