(Test Method)Standard Test Method for Sweep Test of Bituminous Emulsion Surface Treatment Samples
Standard Test Method for Sweep Test of Bituminous Emulsion Surface Treatment Samples
SIGNIFICANCE AND USE
This test method is useful for classifying rapid-setting bituminous emulsions and is applicable to surface treatments that require a quick return to traffic. It has the capability to predict surface treatment performance in the formative stage using construction components. This performance test is intended to evaluate the potential curing characteristics of a binder-aggregate combination to ensure that the surface treatment is sufficiently cured before allowing traffic onto the seal.
SCOPE
1.1 This test method measures the curing performance characteristics of bituminous emulsion and aggregates by simulating the brooming of a surface treatment in the laboratory.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The sweep test is effective for defining the film formation stage of bituminous emulsions. A brush (designed to closely
replicate the sweeping action of a broom) exerts a force on the aggregate used on surface treatments. Bituminous emulsion is
applied to an asphalt felt disk.Aggregate is applied and embedded into the bituminous emulsion. The sample is then conditioned
at a prescribed temperature and time period before testing. A mixer abrades the surface of the sample using a nylon brush. After
one minute of abrasion, the test is stopped, any loose aggregate is removed, and the percent mass loss is calculated.
