Full title and description

ASTM D3910-24 — Standard Practices for Design, Testing, and Construction of Slurry Seal. This practice provides guidance for formulating, testing, and placing slurry seal mixtures used as a surface treatment for pavement preservation and corrective maintenance.

Abstract

ASTM D3910-24 is a concise practice (8 pages) that describes recommended procedures for designing slurry seal mixes (emulsified asphalt with fine-graded aggregate and mineral filler), laboratory and field checks (set/cure and abrasion resistance), and construction/application considerations (mixing, application rates, and equipment). The document is written as a guide and emphasizes adaptation to job-specific end-use specifications.

General information

• Status: Active standard (current edition D3910-24).
• Publication date: October 1, 2024 (edition D3910-24 published 2024).
• Publisher: ASTM International.
• ICS / categories: Road construction / Pavement surface treatments (ICS code commonly cited as 93.080.10).
• Edition / version: D3910-24 (current revision).
• Number of pages: 8 pages.

Scope

The standard covers recommended practices for the design, testing, and construction of slurry seals used as thin surface treatments on pavements. It describes mix components and proportions (emulsified asphalt, fine-graded aggregate, and fillers), laboratory trial mix procedures, performance checks (such as wet-track abrasion and set/cure evaluation), and notes that values are presented in SI units with non-SI units allowed for clarification. The practice is explicitly written as a guide and is not intended to replace job-specific end-use specifications.

Key topics and requirements

• Mix design guidance for slurry seals: recommended emulsion-to-aggregate ratios and trial mix procedures.
• Aggregate grading types (Type I/II/III) and sieve requirements for fine-graded aggregate used in slurry mixtures.
• Performance and laboratory tests: wet-track abrasion (WTAT), set and cure development (cohesion tester), and related acceptance checks.
• Recommended equipment and application procedures: specialized mixing equipment, application rates, and continuous quality-control during placement.
• Guidance on units, safety notes, and the need to adapt the practice to local job and user requirements.

Typical use and users

Primary users include state and local highway agencies, municipal public works departments, pavement contractors, materials laboratories, and consulting pavement engineers. Typical applications are pavement preservation, fog-seal replacements, minor surface rehabilitation, and protective surface coatings on low- to medium-traffic roads. The practice is used to develop trial mixes, establish field acceptance tests, and set equipment/application procedures.

Related standards

Commonly referenced and complementary standards include ASTM test methods and practices for emulsified asphalts and slurry testing — for example, ASTM D6372 (wet track abrasion of slurry surfaces / referenced in slurry testing), ASTM D6934 (residue by evaporation of emulsified asphalt) and related AASHTO tests (T59 family and other binder/residue procedures). Agencies often pair D3910 guidance with ISSA TB specifications and local specification documents for contract use.
