About this file
This is a technical specification document from the Louisiana Department of Transportation and Development (DOTD) establishing standards for aggregate materials used in asphalt surface treatment applications, commonly known as chip seals. The specification details requirements for three sizes of aggregate (Size 1, Size 2, and Size 3) that must be sourced from the Approved Materials List and comply with Subsection 1003.01 of the 2016 Louisiana Standard Specifications for Roads and Bridges. Acceptable aggregate types include crushed gravel, crushed stone, or lightweight aggregate. Size 1 and Size 2 crushed gravel must have a minimum of 60 percent crushed material retained on the No. 4 (4.75 mm) sieve, while Size 3 must have 75 percent crushed material retained on the same sieve. The specification was approved for the Maintenance Division on July 13, 2023, and applies to Product IDs 11478, 11479, 11480, 11481, 11482, and 54750.
The document establishes precise gradation requirements for each aggregate size across multiple sieve sizes, ranging from 1½ inches down to No. 200 (75 micrometers), with specific percent passing ranges specified for slag or stone aggregate and crushed gravel or lightweight aggregate. Special provisions allow uncrushed gravel to be used for Size 1 aggregate if multiple applications of asphalt surface treatment are required. The percentage passing the No. 200 sieve may be 0-2 percent for crushed aggregates when finer materials consist of dust from crushing and handling that is essentially free of clay. Sampling procedures must comply with the Materials Sampling Manual, and percent crushed determination must follow DOTD TR 306 methodology.

SPECIFICATIONS
AGGREGATE FOR ASPHALT SURFACE TREATMENT
DESCRIPTION: This aggregate is for use in asphalt surface treatment applications, sometimes referred to as chip seals.
GENERAL REQUIREMENTS: Aggregate shall be crushed gravel, crushed stone, or lightweight aggregate from the Approved Materials List and comply with Subsection 1003.01 of the 2016 Louisiana Standard Specifications for Roads and Bridges.
SPECIFIC REQUIREMENTS: Crushed gravel Size 1 and Size 2 shall have 60 percent minimum crushed retained on the No. 4 (4.75 mm) sieve. Crushed gravel Size 3 shall have 75 percent crushed retained on the No. 4 (4.75 mm) sieve. Determine the percent crushed in accordance with DOTD
TR 306.

1 The percentage passing the No. 200 (75 μm) sieve shall be 0 - 2 percent for crushed aggregates when the materials finer than the No. 200 (75 μm) sieve consist of dust fraction from crushing and handling, essentially free of clay.
2 Uncrushed gravel may be used for Size 1 aggregate if more than one application of Asphaltic Surface Treatment is required.
SAMPLING: Sampling will be in accordance with the Materials Sampling Manual.
