About this file
This document describes requirements for a Superpave Gyratory Compactor solicitation. The U.S. Army Engineer Research and Development Center requires a gyratory compactor to perform asphalt compaction testing in accordance with ASTM and AASHTO standards. The compactor must have specific dimensions and weight, apply pressures from 600 to 700 kPa, include data acquisition and output capabilities, and be able to compact specimens from 100 to 150 mm in diameter. Additionally, four 150 mm mold assemblies and two 100 mm mold assemblies are required. Freight, installation, and training services should be included in pricing. The related federal contract opportunity is solicitation number W912HZ23Q9478 for a Superpave Gyratory Compactor for the ERDC Geotechnical and Structures Laboratory, issued by the Department of the Army Corps of Engineers Engineer Research and Development Center. Delivery is required by November 30, 2023 to the ERDC facility in Vicksburg, Mississippi.

DESCRIPTION OF REQUIREMENT
Superpave Gyratory Compactor
Purpose and Scope
The Geotechnical and Structures Laboratory (GSL) of the U.S. Army Engineer Research and
Development Center (ERDC), Vicksburg, MS, frequently performs laboratory testing and analysis of asphalt mixtures to characterize their engineering properties. Asphalt mixture specimens must be compacted using a Superpave gyratory compactor (SGC). APB requires an
SGC that can perform asphalt compaction in accordance with ASTM D6925, “Standard Test
Method for Preparation and Determination of the Relative Density of Asphalt Mix Specimens by
Means of the Superpave Gyratory Compactor,” and be capable of providing height versus gyration data.
Description of Requirements
1. Superpave Gyratory Compactor that meets the following requirements:
a. Compliant with AASHTO T312 and ASTM D6925
b. Dimensions: maximum of 36 in. wide by 36 in. deep by 56 in. tall
c. Weight: minimum of 750 lb, maximum of 1,000 lb
d. Electrical: 115 VAC, 60 Hz, 1 ph
e. Applied pressure range: 600 ± 100 kPa at a minimum
f. Gyration angle range: 0.00° to 1.50°
g. Gyration speed: 30 gyrations per minute
h. Compaction modes: (1) to number of gyrations, (2) to specified height, (3) to locking point
i. Data acquisition parameters: number of gyrations, height
j. Data output: USB at a minimum
k. Specimen extrusion: built-in
l. Specimen size range: 100 to 150 mm diameter
m. Include conversion kit for compaction of 100 mm diameter specimens in addition to 150 mm diameter specimens
2. Gyratory Molds
a. Quantity (4) 150-mm mold assemblies
b. Quantity (2) 100-mm mold assemblies
3. Freight, installation, and training should be included in pricing as necessary.
Delivery
By November 30, 2023
ERDC
3909 Halls Ferry Road
Vicksburg, MS 39180
